How To Automate Vulnerability Management

Automating vulnerability management is a process that eliminates repetitive tasks prone to human error and replaces them with data-driven vulnerability prioritization.

There are 5 best practices to keep in mind when automating your vulnerability program including:

  1. Document Data Classifications & Policies.
  2. Understand Your Business Units.
  3. Implement A Policy For Remediation Timelines.
  4. Have Complete Visibility Of Your Environments.
  5. Define Approval Gateways.

IT Security Policy Templates

Vulnerability management benefits cybersecurity by proactively identifying security vulnerabilities and remediating them promptly.

However, while building a vulnerability management program is a critical cybersecurity activity that guards the enterprise network against attackers, maintaining a vulnerability management program at scale is a challenging task for several reasons.

Enterprise IT infrastructure is complex and constantly changing, which makes vulnerability management activities equally complex.

Other factors that contribute to the challenge include an increasingly fast-paced and threatening cyber landscape, and a cyber security talent shortage.

How can enterprises supercharge their vulnerability management programs to overcome these challenges and maintain strong cyber risk assurances?

Automation to the rescue.

Vulnerability management automation offers productivity benefits that alleviate the burden on IT security teams and optimize the effectiveness of vulnerability management operations.

Automation also reduces the potential impact of human error and provides reliable, data-driven vulnerability prioritization.

Let’s examine what automated vulnerability management is, how to automate vulnerability management, and who can benefit from it.

What Is Automated Vulnerability Management?

Vulnerability management proactively scans IT infrastructure for vulnerabilities and remediates them, reducing an organization’s attack surface and the probability of a breach.

Automated vulnerability management automates the workflow of vulnerability management program tasks; particularly the identification, aggregation of associated information, vulnerability assessment reporting, and remediation of vulnerabilities.

Best Practices For Automating Vulnerability Management

1. Document Data Classifications & Policies

All systems and data need to be inventoried, documented, and classified according to their technical specifications and criticality to business operations.

Implement an inventory review process that includes decommissioning processes and timelines.

These key inventories, classifications, and policies allow the calculation of quantified risk scores and prioritization of vulnerabilities according to the real risk that they pose to an organization.

2. Understand Your Business Units

Risk is not distributed evenly throughout an organization.

Each organization has “hot spots” of critical systems and data.

Understanding how each department contributes to overall business operations allows the risk-based design of networks, policies, and controls to restrict access to critical systems and data by reducing the critical attack surface.

3. Implement A Policy For Remediation Timelines

Exposure time” refers to the period between scans when the publication of new vulnerabilities may allow attackers to exploit unpatched vulnerabilities.

Therefore, cyber security vulnerability management relies on scheduling continuous vulnerability scanning to reduce the average time to patch vulnerabilities.

Well-defined SLA/SLO policies help reduce exposure time to satisfy internal risk requirements, and external compliance and regulatory requirements.

4. Have Complete Visibility Of Your Environments

You can’t protect what you can’t see, so creating digital visibility is an important step in developing a vulnerability management program and reliably managing risk.

With a full inventory of systems and data, hardware and software, and a network topography in hand, ensure your scanning and other security tools have visibility of all critical assets in the environment.

5. Define Approval Gateways

Automation of a vulnerability management program still requires human oversight.

Clear communication channels, well-defined standard operating procedures (SOP) and a well-defined understanding of remediation workflows allow vulnerabilities to be patched faster, reducing exposure time and attack surface.

Why Invest In Automation?

Automation can increase the effectiveness and efficiency of vulnerability management activities by reducing the burden on human analysts and ensuring that vulnerabilities are accurately prioritized by aggregating cyber threat intelligence and leveraging the knowledge and skills of industry leading cyber security analysts.

Automated vulnerability management can turn complex processes into simple step-by-step workflows allowing more time to be spent on activities that actually improve network security.

Because cyber security is a high-stakes and fast-paced field with little room for error, it makes perfect sense to optimize cyber security programs with vulnerability management automation

Challenges With Traditional Vulnerability Management

Traditional vulnerability management is resource-intensive, costly, and prone to human error.

Qualified cyber security analysts are hard to find and retain, and the quickly evolving threat environment ensures IT security teams are constantly overwhelmed with threat intelligence data.

This makes the task of accurately prioritizing and remediating vulnerabilities impossible at scale and leads to exposing vulnerable assets to attack for longer than necessary.

Frees Up Resources

Organizations want their IT security team to spend less time trying to figure out what to do and more time doing it.

Automating the aggregation of vulnerability data, its analysis, and the calculation of security priorities supercharges a vulnerability management program.

Actionable information is delivered that can be immediately translated into time spent fixing problems.

Improves Average Time To Patch

In cybersecurity every second counts.

A patch management policy seeks to apply security patches before attackers identify the vulnerabilities and exploit them.

Automation provides immediate access to enriched vulnerability information as new vulnerabilities are disclosed and security updates are released, reducing the average time to patch a vulnerability.

Provided with the right information at the right time, organizations can reliably meet and exceed their compliance obligations, reduce their vulnerable attack surface, and achieve a greater return on security investment (ROSI) faster.

When Should You Consider Automation?

If you are unsure about your organization’s ability to manage a cyber attack or don’t have an in-house IT security team, automated vulnerability management is an opportunity to streamline security operations, strengthen operational resiliency, and gain strong cyber risk assurances.

Here are some telltale scenarios that indicate your organization will benefit from automated vulnerability management technologies:

  • You Don’t Have A Vulnerability Management Program
  • You Want Peace Of Mind
  • You Are A Rapidly Growing Organization
  • Evolve To The Next Generation Of Vulnerability Management

You Don’t Have A Vulnerability Management Program

The top priority for businesses is growth, but a successful cyber attack can be a huge financial setback and lead to a damaged public reputation.

SMEs and start-ups are not immune to cyber attacks either.

On the contrary, attackers consider them prime targets because they are less likely to have user-awareness training programs and well-developed cybersecurity programs.

For organizations of all sizes, new regulations, and compliance requirements are also pushing organizations to expand their cybersecurity programs.

In all of these cases, adding automation to a vulnerability management program provides improved efficiency and reliability.

You Want Peace Of Mind

Recent security statistics relay the increasing risk that cyber attacks pose to businesses.

How can leaders and decision-makers achieve peace of mind as digitization introduces new and complex risks?

The most effective way is to partner with qualified cybersecurity professionals to develop world-class cyber resilience supported by next-generation cybersecurity technologies.

Next-generation vulnerability management supports compliance requirements and provides on-demand risk visibility and vulnerability assessment reporting across the entire IT environment, allowing an organization to stay ahead of the bad guys.

You Are Rapidly Growing

Successful companies can grow in the blink of an eye.

However, growth comes with increased attack surface and risk.

As companies scale services they handle a larger amount of sensitive data and protect higher revenues.

Automating a vulnerability management program supercharges IT and Infosec staff, providing them with reliable the critical data they need to more quickly address a higher number of data-driven security priorities.

Personnel can spend more time remediating vulnerabilities and less time manually aggregating, researching, and analyzing vulnerability information.

Evolve To Next Generation Vulnerability Management

Traditional approaches to vulnerability and patch management rely on human analysts and their best judgment to prioritize vulnerabilities.

However, the “human factor” puts an organization at risk of arbitrary and ad-hoc prioritization.

Quantitative data-driven prioritization delivered by next-generation cyber security technologies is more reliable and actionable allowing more efficient and effective cyber security operations.

Automated vulnerability management is a next-generation technology that provides access to leading IT security professionals and delivers accurate quantitative analytics for data-driven prioritization and risk visibility

Common Challenges Of Implementing Automation

While automation can reduce the efficiencies of traditional vulnerability management, the automation of vulnerability management activities also includes unique challenges.

Let’s examine the biggest challenge to implementing more automated processes in a vulnerability management program:

  • Preparing To Automate A Vulnerability Management Program
  • Changing Your Processes
  • Network Challenges

Preparing To Automate A Vulnerability Management Program

Before an organization can automate vulnerability management activities, the best practices outlined above need to be in place.

However, these initial steps within themselves are no easy task. Enterprise IT infrastructure is a complex highly distributed architecture.

An organization’s entire business workflow and IT infrastructure must be carefully architected, inventoried, and classified before the vulnerability management automation process can begin.

Changing Your Processes

Change isn’t easy, but failure to stay up-to-date with IT security imposes huge risks.

A cyber security talent shortage, high staff turnover rate, and a fast-paced technological change impose burdens that smart businesses want to overcome.

The long-term benefits of a vulnerability management automation process far outweigh the initial burden of changing current practices and ensure that an organization’s cybersecurity efforts can keep pace with sustained technological change.

Network Challenges

It’s important to make sure your network is well architected and configured for an organization’s unique business operations and ongoing maintenance of good cyber hygiene is a must.

This includes mapping internal network topography including:

  • Wireless access points and SD-WAN.
  • Maintaining updated software inventories for accept and block lists of each asset.
  • Continuously monitor network and service configurations for unauthorized changes.

Wrapping Up

 

The modern cyber security landscape is complex and high costs are associated with even a single breach.

Many companies are not adequately protected, at a time when it’s more important than ever to retain access to leading IT security talent.

Automated vulnerability management reduces the burden on internal IT security team members, the potential for human error, and enables more efficient and effective data-driven prioritization of vulnerability remediation.

PurpleSec’s Cyber Risk Management Platform automates vulnerability program activities including scanning, data aggregation, and prioritization to deliver risk visibility, on-demand reporting, and remediation.

Our approach ensures that IT team members spend less time trying to figure out what to do and more time improving network security.

Reporting the results from vulnerability scanning without a set of clearly defined metrics is an issue many organizations face today.

Presenting vulnerability reports to senior management without key metrics will also limit your ability to effectively communicate the overall risk of your organization.

Learn More: Cybersecurity Metrics And KPIs CISOs Use To Prove Business Value

Faulty reporting of vulnerability metrics not only creates blind spots for your security and infrastructure team, but your executive leadership and stakeholders will not understand the true value of the vulnerability program and will question the return on this security investment.

In this article, we will help you identify and define the top key metrics that your organization can implement to track the progress and state of your vulnerability and patch management programs.

We will also discuss the differences in KPI’s and demonstrate how PurpleSec can help you measure and report on successes.

Let’s now take a look at why vulnerability metrics are critical to your program.

Why Vulnerability Metrics Are Critical To Program Success

Vulnerability metrics are critical to the successful measurement of your vulnerability management program.

They measure the status of your remediation strategy and patching effectiveness.

Without a consistent system of reporting the status of your program, the likelihood of exposure to a data breach increases as reported in recent breach statistics.

When considering which metrics to report, the approach should not be to simply gather statistics and charts, but it should focus on prioritizing remediation efforts on of your most critical systems and applications.

The steps to gather the right metrics for your organization will take care planning by your IT and security teams.

This can be accomplished by understanding the importance of gathering metrics.

Note the following four areas that can help you get started:

Risk Awareness

Metrics quantify the state of risk of your organization into a format your teams and stakeholders can understand.

The right metrics can also elevate risk awareness and understanding for your business leaders to support the vulnerability management program.

Planning

A consistent program for gathering metrics can help your organization plan for reducing risk each time a new application or system is introduced into the environment.

This approach can also evaluate if business objectives are met and if additional resources are required.

Audits

If metric reporting is already an established process of your vulnerability program, your internal or third-party audits will more than likely result in success.

NIST and CMCC compliance requirements can help you identify weaknesses in your vulnerability program.

Resource Allocation

Metrics can help pinpoint areas of risk within key business applications or at the development stage.

Once identified, your leadership teams can determine where and if additional resources are needed to reduce risk or close gaps within the system

Top 10 Vulnerability And Patch Management Metrics

Depending on the type of vulnerability scanner, a few of these metrics may already be pre-built into the reporting engine.

If you choose to customize your report, review the context of each metric and select as needed to fit your organization’s needs.

1. Average Time To Action

This important metric reveals how responsive your team reacts to the results of the reported vulnerabilities.

This metric should be consistently low since the security team is accountable for delivering the message and action plans for remediation to business owners.

2. Mean Time To Remediation

Mean time to remediation should be based on a documented SLA defined in your Vulnerability Management Policy.

The severity of the vulnerability should have a corresponding relative or an absolute period of time for planning and remediation.

3. Risk Score

This value is usually automatically calculated from the vulnerability report. This score illustrates the cumulative risk of your vulnerabilities per severity level, i.e. Critical, High, or Medium.

4. Accepted Risk Score

If your organizations decide not patch a specific or group of vulnerabilities within a specified time period, this is an acceptance of risk.

Acceptance of risk should be tracked, scored, and reported to help the organization understand the potential for exposure and the risk that has been accepted.

5. Average Vulnerability Age

The vulnerability age is the number of days since a vulnerability was publicly disclosed. Tracking this metric will help your organization create remediation plans that aligns with your SLA.

6. Internal Vs External Exposure

Your external internet facing applications inherently are at highest exposure to outside threats compared to internal. An organization should have separate scanners for each environment.

Although an external scan has high priority, internal scans should be prioritized as well due to the potential of a threat actor entering your network and exploiting a threat is always probable.

7. Rate Of Recurrence

A remediated vulnerability that returns on the same or different asset may indicate a problem with the baseline configuration or lack thereof.

Tracking this metric continuously will enable your infrastructure teams to closely review process errors or system configuration issues.

8. Total Risk Remediated

Total risk remediated is a key metric that illustrates the effectiveness of your vulnerability management program to your IT and executive management teams.

When your total risk remediation is trending upward continuously, this may demonstrate to your business stakeholders the effectiveness of your security investment.

9. Asset Inventory/Coverage

This metric identifies the number of assets that should be patched. The vulnerability management tool should have auto discovery functionality to detect new systems on the network.

Tracking this metric will help you identify how your environment is trending, or if new assets are added and serviced by a ticketing or inventory system.

10. Service Level Agreement (SLA)

The Service Level Agreement determines when a patch is expected to be remediated. This value should be documented within your vulnerability management policy.

This metric is the baseline tracker for remediation – i.e., Zero-day attacks may require immediate remediation, a Critical Severity finding may have a duration of 7 days.

SLA values may also be dependent on the priority of the asset as well, per your organization’s needs.

Less Important KPIs

The following metrics provide useful data on detection times, severity detail, and quantity of vulnerabilities.

They are considered less important due to their lack of direct impact on risk reduction.

Mean Time To Detect

Mean Time to Detect is the average amount of time between the beginning of a vulnerability and the discovery of the vulnerability by your IT or security team.

Although this is a useful metric, the most important takeaway from this vulnerability is the action to be performed after it’s detected.

In addition, when deploying a continuous vulnerability solution, your mean time to detect should be days or hours – not weeks or months.

Average CVSS Scores

Common Vulnerability Scoring System (CVSS) provides a numerical representation of the severity of a vulnerability to help incident responders prioritize remediation efforts.

Although CVSS scoring does not directly indicate risk, it can provide valuable insight into software or systems that may be at risk.

Open Vulnerabilities

Tracking open vulnerabilities is a useful metric that illustrates your current technical debt across all of your systems. The numerical value of open vulnerabilities is not a risk rating.

The value of the metric is realized when combined with other metrics to prioritize a vulnerability remediation process for critical systems.

How To Measure Successful Vulnerabilities Management Outcomes

So far, we’ve defined why metrics are important for reporting and identified top metrics that should be included in your reports.

In this section, the goal is to ensure you are capturing data from all sources within your network.

Once this data is consumed into your reports, you will be in a position to tell the story with your results.

Obtain Reports From All Sources

It is important to understand the type and whereabouts of all assets connected to your network. Assets not accounted for may result in unpatched systems and inaccurate reporting of your risk posture in network vulnerability reports.

Include reporting from your blue and red team tools to provide comprehensive insights into your vulnerability management lifecycle.

The outcome will result in better prioritization of remediation plans of your most critical systems through validation.

This inclusive reporting approach will enable your teams to identify targets for further testing.

Centralize Metrics With Dashboard Reporting

Multiple reporting dashboards for each tool can make demonstrating results difficult to manage.

Centralizing your reporting into a single pane makes it easier for your organization to observe the positive impact your vulnerability program, which leads to more success.

Present Metrics Based on The Story You Need to Tell

Present the most important KPIs first based on your organization’s needs.

Your stakeholders need to know what the risk impact is to the business. Present the metrics that focus on the priority of critical systems and risk that have been accepted.

Present metrics that match the SLA’s documented in your vulnerability management policy. This will demonstrate the timeliness of patching systems to reduce your overall risk profile.

Let’s now take a look at how PurpleSec can help improve your reporting capabilities with automation.

Let’s be honest, no business wants to expose itself to risk. Or, worse yet, be the headline story of the latest cyber attacks.

Recent research suggests that 60% of breaches involved unpatched vulnerabilities.

One way to mitigate this risk is by performing routine vulnerability assessments.

In this article, I’m going to break down each of these steps to show you exactly how to perform a vulnerability test for your organization.

By the end, you will have a better understanding of the complete vulnerability assessment process and what you need to do to lay the foundation for a successful cybersecurity program.

What Is A Vulnerability Assessment?

A vulnerability assessment is a process of identifying security vulnerabilities in systems, quantifying and analyzing them, and remediating those vulnerabilities based on predefined risks.

Assessments are an essential part of a holistic security program and are cited by many industry standards and compliance regulations.

The vulnerability assessment example below identifies and categorizes vulnerabilities found on a network.

Purplesec network vulnerability assessment report

A security expert conducts vulnerability analysis of the network scans to prioritize threats identified. From this, an action plan can be created with steps to remediate vulnerabilities.

For example, maintaining up-to-date patches and implementing a patch management procedure may be a valid recommendation.

Read MoreHow To Develop & Implement A Network Security Plan

Vulnerability Assessment Pricing & Frequency

Vulnerability assessment costs vary, but you can expect to pay between $2,000 – $4,000 per report.

The complexity of the network and the goals of the assessment often determine the cost of a scan.

Many security professionals consider it best practice to perform vulnerability assessments at least quarterly, however, there are several factors to consider including compliance, changes in infrastructure, and business needs.

With the growing threat landscape, it is not uncommon for organizations to adopt a continuous vulnerability management solution.

What Are The Steps In The Vulnerability Assessment Process?

Step 1: Conduct Risk Identification And Analysis

step 1 - conduct risk identification an analysisIdentifying risks for each asset and possible threats they face is a complex task. 

The most important thing is to structure the process well so that nothing important slips through the cracks. Companies can accomplish this by structuring their asset registers with added columns for threats and vulnerabilities.

This way, you will have a centralized document with all the necessary information needed. After you assign threats and vulnerabilities to your assets, you can begin the analysis phase where you assign risks to assets by determining the impact and likelihood of each threat materializing.

Once complete, you can finally focus on prioritizing assets that have the highest risk assigned and those most critically affected by known weaknesses or vulnerabilities.

Step 2: Vulnerability Scanning Policies and Procedures

step 2 - develop vulnerability scanning policiesTo have a structured and successful scanning methodology, policies and procedures must exist in order to have a pre-determined course of action needed to be taken. This includes all aspects of vulnerability scanning.

For starters, the policy or a procedure should have an official owner that is in responsible for everything that is written inside.

Free Download: Sample Vulnerability Assessment Policy

The policy should also be approved by upper management before taking effect. Defining the frequency of scanning is also important due to compliance adherence.

From a technical perspective, everything regarding the vulnerability scan configuration and functionality should be emphasized and written down. 

The document should also include steps to be taken after the scan is complete.

The most important factors are the types of scans that will be conducted, the ways the scans will be performed, software solutions used, which vulnerabilities take precedence over others, and steps that need to be taken after the scan is complete.

Step 3: Identify The Types Of Vulnerability Scans

step 3 - identify the type of scansVulnerability scanning is a process where vulnerability scanning software is used to identify security weaknesses in information systems.

Vulnerability scanning can be performed by network administrators, information security analysts and all technical IT staff that are trained and assigned the function of conducting a vulnerability scan.

Most malicious hackers attempt to map a network by scanning the system and trying to find possible vulnerabilities to gain unauthorized access to information systems. If malicious hackers you are trying to defend against use vulnerability scanning techniques, you have no choice but to employ them as well in order to stay ahead of their game.

Depending on the software that is running on the system you need to scan and secure, you need to determine the type of scan to be performed in order to get the most benefits.

The most common types of vulnerability scans include:

How Often Should You Perform A Network Vulnerability Scan

Network Vulnerability Scans

The most common type of vulnerability scan is a network-based scan.

This scan includes networks, their communication channels, and the networking equipment used in an environment.

Some of the major software and hardware devices that are in the scope of a network scan are hubs, switches, routers, firewalls, clusters, and servers.

A network scan will detect and classify all vulnerabilities that it finds on these devices.

Host Based Vulnerability Scans

Host-based scan is often misunderstood as being the same as a network scan.

Far from the truth, host-based scans address vulnerabilities related to hosts on the network including computers, laptops, and servers.

More specifically, this scan investigates:

  • The host configuration.
  • Its user directories.
  • File systems.
  • Memory settings.
  • Other information that can be found on a host.

This scan focuses more on the endpoints and their internal system setup and functionality.

The importance of a host-based scan is also often overlooked.

If neglected, misconfigurations and dormant vulnerabilities that lie in endpoints can mean disaster for your company if a malicious hacker manages to penetrate past your perimeter.

By neglecting host-based scans malicious actors can move laterally through the system with far more ease.

Web Application Penetration Testing - Types Of Penetration Testing

Application Based Vulnerability Scans

An application vulnerability scan is often forgotten and is in the shadows of an application penetration test.

Nevertheless, if you are not conducting an application penetration test, scanning your applications for vulnerabilities should be very high on your priority list.

By choosing from a variety of application vulnerability scanning tools, you can automate your security tasks and increase the security of your applications.

There is a variety of tools that you can use, both open-source and commercial to conduct a true application vulnerability scan.

Wireless Penetration Testing - Types Of Penetration Testing

Wireless Based Vulnerability Scans

To conduct a successful wireless vulnerability scan you need to know all the wireless devices that are in your network.

Additionally, you need to map out the attributes for each device to know how to properly configure the scan.

The next step is to identify any rouge access points that might be in your network and isolate those unknown devices.

It is important to remove these devices from your network as they might be listening in on your wireless traffic.

After all of the above, you can start testing your wireless access points and your wireless LAN infrastructure.

Step 4: Configure The Scan

step 4 - configure the scanEven though there are many vulnerability scanning vendors to choose from, the configuration of any scan can still be addressed.

This is done by identifying general objectives and the type of system you want to scan.

To configure a vulnerability scan you must:

  • Add A List Of Target IPs – The IP addresses where the target systems are hosted need to be inputted into the vulnerability scanning software in order for a scan to be performed.
  • Defining Port Range And Protocols – After adding the target IPs it is important to specify the port range you want to scan and which protocol you wish to use in the process.
  • Defining The Targets – In this step, you need to specify if your target IPs are databases, windows servers, applications, wireless devices etc. By making your scan more specific, you will get more accurate results.
  • Setting Up The Aggressiveness Of The Scan, Time And Notifications – Defining how aggressive your scan will be can influence the performance of the devices you are going to scan. To avoid any downtime on the target systems, it is recommended to set up a scan to be executed at a certain time, usually non-business hours. Additionally, you can also setup to receive a notification when the scan is complete.

Step 5: Perform The Scan

step 5 - perform the scanAfter determining the type of scan you want to conduct, and after setting up the configuration of the scan, you can save the configuration and run as desired.

Depending on the size of the target set and the intrusiveness of the scan, it can take minutes to hours for it to complete.

Each vulnerability scan can be divided into three phases:

  1. Scanning
  2. Enumeration
  3. Vulnerability Detection

In the scanning phase, the tool you are using will fingerprint the specified targets to gather basic information about them.

With this information, the tool will proceed to enumerate the targets and gather more detailed specifications such as ports and services that are up and running.

Finally, after determining the service versions and configuration of each target IP, the network vulnerability scanning tool will proceed to map out vulnerabilities in the targets, if any are present.

Step 6: Evaluate And Consider Possible Risks

step 6 - evaluate and consider possible risksRisks associated with performing a vulnerability scan pertain mostly to the availability of the target system. 

If the links and connections cannot handle the traffic load generated by the scan, the remote target can shut down and become unavailable.

When performing a scan on critical systems and production systems, extra caution should be exercised, and the scan should be performed after hours when the traffic to the target is minimal, in order to avoid overload.

Step 7: Interpret The Scan Results

step 7 - interpret the scan resultsHaving qualified staff members configuring, performing and analyzing the results of a vulnerability scan is most important. 

Knowledge of the scanned system is also important in order to properly prioritize remediation efforts. 

Even though each vulnerability scanning tool will prioritize vulnerabilities automatically, certain types of vulnerabilities should be given a priority.

For example, remote code execution vulnerabilities should take precedence over possible DDOS and encryption vulnerabilities. 

It’s important to consider the likelihood and the effort needed in order for a hacker to exploit the found vulnerability.

If there is a public exploit available for a vulnerability that you found in your system, giving priority to that vulnerability should take precedence over other vulnerabilities found that are exploitable but with far more effort.

Step 8: Create A Remediation Process And Mitigation Plan

step 8 - create a remediation and mitigation planAfter interpreting the results, information security staff should prioritize the mitigation of each vulnerability detected and work with IT staff in order to communicate mitigation actions. 

The Information security staff and IT staff need to communicate and work closely together in the vulnerability mitigation phase in order to make the process successful and fast.

Numerous follow-up scans are usually performed during the back and forth problem-solving between teams until all vulnerabilities that need to be mitigated no longer appear in the reports.

Conclusion

Vulnerability Assessments are a complex process that is always ongoing.

Due to the constant changes in technology in the modern era and with the increased number of successful attacks being launched at all major companies, these assessments have become the backbone for a successful defense of any information system.

It is a process that is heavily based on previously determined assets and their assigned risk due to the need to prioritize security issues to deflect the most damage that could arise from a successful cyber-attack.

The benefits associated with performing regular vulnerability assessments are enormous. 

From serving as an aid in the process of system hardening to being an integral requirement of most compliance standards, vulnerability assessments also allow you to maintain a good security posture and contribute to the success of your company’s cyber security program.

The complex vulnerability scanning tools allow you to build your configurations and run scans on a vast number of different devices.

This gives your business the ability to assess its infrastructure in a sound and complete way, covering all fronts, for network, host, wireless and application-level vulnerabilities.

Vulnerability Management

What Is Vulnerability Management? (The Definitive Guide)

Managing vulnerabilities continues to be a struggle for many organizations today. It’s not enough to ‘check the box’ and say we have a tool that does vulnerability scanning without actively addressing the report details.

Hackers are now targeting specific industries because they know which sectors are prone to their attacks.

A recent report found 22,514 vulnerabilities were reported in 2022, which was the highest reported since 2009. These statistics highlight the importance of having a vulnerability management program for your organization.

In this article, I will review the core components and benefits of an efficient vulnerability management program. I’ll also highlight the importance of continuously automating your scan processes to stay ahead of the game in 2024.

What Is Vulnerability Management?

Vulnerability Management is the continuous process of discovering, assessing, verifying, prioritizing, remediating, and reporting vulnerabilities in systems and software.

The process of vulnerability management seeks to minimize the probability of exposures to threats that may impact the availability of critical business systems.

Vulnerability management is an integral component of your security program.

what is vulnerability management

Treating vulnerability management as part of your security program creates synergy with other security systems to help you adapt to the constantly changing threat and attack landscape.

Building out a vulnerability management process can be achieved by understanding the various components that comprise the program.

Components of Vulnerability Management

ProcessResponsibilityDurationFrequencyCostTools
Vulnerability ScanningSecurity team – analyst or engineer.1-2 hours to setup and 1-2 hours to scan.Ideally daily or weekly at a minimum.$5,000+/year.Qualys, Rapid7, Acunetix, Nessus, Managed Engine.
Vulnerability AssessmentSecurity team – analyst or engineer.3-5 hours of report writing.Once per week or once per month.$2,500 – $10,000/year.Imperva, Nmap, Burpsuite, Invicti, OpanVas.
Patch ManagementInfrastructure teams usually manage along with business owner approval.Usually 24 – 48 hours.At least weekly, ideally daily.$5-$10/month per endpoint.Microsoft SCCM, Avast, Kaseya, NinjaOne, Atera.
Vulnerability RemediationShared responsbility, including infrastructure teams and involves business team support.30 days at a minimum; ideally every 9-12 days.At least weekly, ideally daily.$5-$10/month per endpoint.PurpleSec

The components of vulnerability management are separate processes that are handled by the overall vulnerability management program.

Let’s now define each process and how they fit together into the scope of a comprehensive vulnerability management strategy.

How Often Should You Perform A Network Vulnerability Scan

Vulnerability Scanning

Vulnerability scanning can be described as the act of performing an inspection of internal/external addresses or assets managed by the organization.

This inspection includes:

  • Scanning external websites/applications
  • Network port scans
  • Internal servers
  • IoT Devices
  • Cloud Services

Vulnerability Assessment

Vulnerability Assessments are periodic reviews of security weaknesses detected in an information endpoint or application.

The detection report provides a detailed review of a system’s susceptibility to an exploit and assigns a category ranking.

The assessment also guides how to remediate the findings.

Patch Management

If you were to compare vulnerability management and patch management, patch management operationalizes the effort in applying patches to a system, and is a component of vulnerability management.

Vulnerability Remediation

A vulnerability remediation process determines and addresses weaknesses in assets, systems, or applications. The remediation process is driven by the Service Level Agreement (SLA) as documented in your Vulnerability Management policy.

This is an essential component since it establishes the timeliness of remediation and establishes ongoing vulnerability remediation best practices.

Now that we have discussed the basic foundational components of vulnerability management best practices, let’s now review the key benefits of putting this all together to round out the program.

Benefits of Vulnerability Management

If your organization does not have a robust vulnerability management program, your organization is at risk of cyber attacks that may threaten the availability of your business systems.

To counter this risk, let’s take a look at the 3 core benefits of vulnerability management.

One of the key steps in managing vulnerabilities in the cloud is defining the key vulnerability management metrics for your environment.

In this section, we will walk through the steps to establish key metrics and how you can prepare to stay current on monitoring threats to your cloud systems.

Improved Security Posture

Vulnerability management enhances the overall security posture of your organization by providing visibility and recognition of on premise and key external web assets.

Reduced Risk of Cyber Attacks

Implementing an automated and continuous patch management process ensures immediate identification of vulnerabilities, sets prioritization, and allocates resources to remediate critical vulnerabilities, which in turn reduces the risk of cyber attacks.

Maintain Compliance Requirements

Effective vulnerability management will help your organization to achieve regulatory compliance.

Compliance frameworks such as the Payment Card Industry (PCI) and the Health Insurance Portability and Accountability Act (HIPAA) require organizations to maintain a vulnerability management program.

Now that we understand the core benefits of the vulnerability management program, let’s now explore another key component, the Vulnerability Management policy.

The Importance Of Having A Vulnerability Management Policy

As explained, the main benefits of the vulnerability management program are to secure the network from threats, improve your organization’s security posture, and stay compliant with regulatory requirements.

But how do you ensure teams that the program is communicated and enforced? The answer is a vulnerability management policy.

The purpose of the policy is to provide guidance not only for your security teams but to establish a standard set of processes that explains in detail each component of the program.

Details that should be included in the policy:

  • Asset identification – Describes the assets that are in scope for scanning.
  • Vulnerability scan frequency – Defines how often the scans are conducted.
  • SLA (Service Level Agreement – Defines the time frames vulnerabilities should be remediated.
  • Exception process – Describes the criteria and approval process for vulnerabilities that cannot be remediated promptly.

Future Trends And Predictions for Vulnerability Management In 2024

Based on trends from 2023, the prevalence of threats and vulnerabilities exploited in the wild is not slowing down.

To stay ahead of the attacks, security leaders are looking for innovative solutions to continuously monitor the networks and minimize risk with tighter budgets.

Let’s explore a few emerging technologies that will impact the way your organization approaches vulnerability management in 2023 and in the future.

Automation Of Vulnerability Management Processes

Automating vulnerability management that incorporates machine learning algorithms is one method security teams can implement to continuously identify and evaluate threats. This level of scanning increases efficiency and reduces technical debt by automating remediation.

Continuous Vulnerability Monitoring

As the name implies, continuous involves regularity and consistency. Continuous vulnerability scanning allows for creative scheduling and ongoing discovery of threats.

The output of continuous scanning produces valuable reports that provide real-time information on vulnerabilities and threats that exist in your infrastructure.

This approach allows your organization to develop a continuous vulnerability management solution that reduces overall risk to your environment.

Best Practices For Cloud Vulnerability Management in 2023

Managing Vulnerabilities In The Cloud

Managing vulnerabilities in the cloud involves ensuring that cloud-based systems are regularly updated and patched, as well as monitoring for new vulnerabilities and implementing appropriate controls to mitigate risks.

Knowledge of applying best practices for managing vulnerabilities in the cloud is necessary to ensure assets are properly identified for scanning.

Once the infrastructure is established for cloud scanning, the procedures and vulnerability policies can be enforced as usual.

Focus On Cyber Resilience

Cyber resilience refers to an organization’s ability to prepare and recover quickly from an attack to continue operating in the face of ongoing threats.

When an organization focuses on cyber resilience, it will identify the most critical applications that have the highest business impact.

The organization can then leverage the vulnerability management program to prioritize scanning on these systems to proactively identify potential threats, which in turn establishes the foundation for a risk-based vulnerability management process for your organization.

Wrapping Up

In this article, we have described the various components of an efficient vulnerability management program.

We reviewed how each component integrates into the scope of the overall vulnerability program.

We also emphasized the importance of adopting automation and machine learning into your scanning processes.

Lastly, we reviewed the importance of managing vulnerabilities in the cloud along with the benefits of implementing cyber resilience, which is an effective technique when coupled with a continuous vulnerability management process.

As we look forward to another exciting and challenging year, continue to be vigilant in protecting your systems by implementing and maintaining an efficient vulnerability management program that secures your organization in 2024.
