Implement Risk-Based Vulnerability Management

Get off the patching merry-go-round and start mitigating risk!

  • Vulnerability scanners, industry alerts, and penetration tests are revealing more and more vulnerabilities, and it is unclear how to manage them.
  • Organizations are struggling to prioritize the vulnerabilities for remediation, as there are many factors to consider, including the threat of the vulnerability and the potential remediation option itself.

Our Advice

Critical Insight

  • Patches are often seen as the only answer to vulnerabilities, but these are not always the most suitable solution.
  • Vulnerability management does not equal patch management. It includes identifying and assessing the risk of the vulnerability, and then selecting a remediation option which goes beyond just patching alone.
  • There is more than one way to tackle the problem. Leverage your existing security controls in order to protect the organization.

Impact and Result

  • At the conclusion of this blueprint, you will have created a full vulnerability management program that will allow you to take a risk-based approach to vulnerability remediation.
  • Assessing a vulnerability’s risk will enable you to properly determine the true urgency of a vulnerability within the context of your organization; this ensures you are not just blindly following what the tool is reporting.
  • The risk-based approach will allow you prioritize your discovered vulnerabilities and take immediate action on critical and high vulnerabilities, while allowing your standard remediation cycle to address the medium to low vulnerabilities.
  • With your program defined and developed, you now need to configure your vulnerability scanning tool, or acquire one if you don’t already have a tool in place.
  • Lastly, while vulnerability management will help address your systems and applications, how do you know if you are secure from external malicious actors? Penetration testing will offer visibility, allowing you to plug those holes and attain an environment with a smaller risk surface.

Implement Risk-Based Vulnerability Management Research & Tools

Start here – read the Executive Brief

Read our concise Executive Brief to find out why you should design and implement a vulnerability management program, review Info-Tech’s methodology, and understand the four ways we can support you in completing this project.

1. Identify vulnerability sources

Begin the project by creating a vulnerability management team and determine how vulnerabilities will be identified through scanners, penetration tests, third-party sources, and incidents.

2. Triage vulnerabilities and assign priorities

Determine how vulnerabilities will be triaged and evaluated based on intrinsic qualities and how they may compromise business functions and data sensitivity.

3. Remediate vulnerabilities

Address the vulnerabilities based on their level of risk. Patching isn't the only risk mitigation action; some systems simply cannot be patched, but other options are available. Reduce the risk down to medium/low levels and engage your regular operational processes to deal with the latter.

4. Measure and formalize

Evolve the program continually by developing metrics and formalizing a policy.

Analyst Perspective

Vulnerabilities will always be present. Know the unknowns!

In this age of discovery, technology changes at such a rapid pace. New things are discovered, both in new technology and in old. The pace of change can often be very confusing as to where to start and what to do.

The ever-changing nature of technology means that vulnerabilities will always be present. Taking measures to address these completely will consume all your department’s time and resources. That, and your efforts will quickly become stale as new vulnerabilities are uncovered. Besides, what about the systems that simply can’t be patched? The key is to understand the vulnerabilities and the levels of risk they pose to your organization, to prioritize effectively and to look beyond patching.

A risk-based approach to vulnerability management will ensure you are prioritizing appropriately and protecting the business. Reduce the risk surface!

Vulnerability management is more than just systems and application patching. It is a full process that includes patching, compensating controls, segmentation, segregation, and heightened diligence in security monitoring.

Executive Summary

Your Challenge

Vulnerability scanners, industry alerts, and penetration tests are revealing more and more vulnerabilities, and it is unclear how to manage them.

Organizations are struggling to prioritize the vulnerabilities for remediation, as there are many factors to consider, including the threat of the vulnerability and the potential remediation option.

Common Obstacles

Patches are often seen as the answer to vulnerabilities, but these are not always the most suitable solution.

Some systems deemed vulnerable simply cannot be patched or easily replaced.

Companies are unaware of the risk implications that come from leaving the vulnerability open and from the remediation option itself.

Info-Tech’s Approach

Design and implement a vulnerability management program that identifies, prioritizes, and remediates vulnerabilities.

Understand what needs to be considered when implementing remediation options, including patches, configuration changes, and defense-in-depth controls.

Build a process that is easy to understand and allows vulnerabilities to be remediated proactively, instead of in an ad hoc fashion.

Info-Tech Insight

Vulnerability management does not always equal patch management. There is more than one way to tackle the problem, particularly if a system cannot be easily patched or replaced. If a vulnerability cannot be completely remediated, steps to reduce the risk to a tolerable level must be taken.

Common obstacles

These barriers make vulnerability management difficult to address for many organizations:
  • The value of vulnerability management is not well articulated in many organizations. As a result, investment in vulnerability scanning technology is often insufficient.
  • Many organizations feel that a “patch everything” approach is the most effective path.
  • Vulnerability management is commonly misunderstood as being a process that only supports patch management.
  • There is often misalignment between SecOps and ITOps in remediation action and priority, affecting the timeliness of remediation.

Leverage risk to sort, triage, and prioritize vulnerabilities

Reduce your risk surface to avoid cost to your business; everything else is table stakes.

Reduce the critical and high vulnerabilities below the risk threshold and operationalize the remediation of medium/low vulnerabilities by following your effective vulnerability management program cycles.

Identify vulnerability sources

An inventory of your scanning tool and vulnerability threat intelligence data sources will help you determine a viable strategy for addressing vulnerabilities. Defining roles and responsibilities ahead of time will ensure you are not left scrambling when dealing with vulnerabilities.

Triage and prioritize

Bring the vulnerabilities into context by assessing vulnerabilities based on your security posture and mechanisms and not just what your data sources report. This will allow you to gauge the true urgency of the vulnerabilities based on risk and determine an effective mitigation plan.

Remediate vulnerabilities

Address the vulnerabilities based on their level of risk. Patching isn't the only risk mitigation action; some systems simply cannot be patched, but other options are available.

Reduce the risk down to medium/low levels and engage your regular operational processes to deal with the latter.

Measure and formalize

Upon implementation of the program, measure with metrics to ensure that the program is successful. Improve the program with each iteration of vulnerability mitigation to ensure continuous improvement.

Tactical Insight 1

All actions to address vulnerabilities should be based on risk and the organization’s established risk tolerance.

Tactical Insight 2

Reduce the risk surface down below the risk threshold.

The industry has shifted to a risk-based approach

Traditional vulnerability management is no longer viable.

“For those of us in the vulnerability management space, ensuring that money, resources, and time are strategically spent is both imperative and difficult. Resources are dwindling fast, but the vulnerability problem sure isn’t.” (Kenna Security)

“Using vulnerability scanners to identify unpatched software is no longer enough. Keeping devices, networks, and digital assets safe takes a much broader, risk-based vulnerability management strategy – one that includes vulnerability assessment and mitigation actions that touch the entire ecosystem.” (Balbix)

“Unlike legacy vulnerability management, risk-based vulnerability management goes beyond just discovering vulnerabilities. It helps you understand vulnerability risks with threat context and insight into potential business impact.” (Tenable)

“A common mistake when prioritizing patching is equating a vulnerability’s Common Vulnerability Scoring System (CVSS) score with risk. Although CVSS scores can provide useful insight into the anatomy of a vulnerability and how it might behave if weaponized, they are standardized and thus don’t reflect either of the highly situational variables — namely, weaponization likelihood and potential impact — that factor into the risk the vulnerability poses to an organization.” (SecurityWeek)

Why a take risk-based approach?

Vulnerabilities, by the numbers

60% — In 2019, 60% of breaches were due to unpatched vulnerabilities.

74% — In the same survey, 74% of survey responses said they cannot take down critical applications and systems to patch them quickly. (Source: SecurityBoulevard, 2019)

Info-Tech Insight

Taking a risk-based approach will allow you to focus on mitigating risk, rather than “just patching” your environment.

The average cost of a breach in 2020 is $3.86 million, and “…the price tag was much less for mature companies and industries and far higher for firms that had lackluster security automation and incident response processes.” (Dark Reading)

Info-Tech’s vulnerability management methodology

Focus on developing the most efficient processes.

Vulnerability management isn’t “old school.”

The vulnerability management market is relatively mature; however, vulnerability management remains a very relevant and challenging topic.

Security practitioners are inundated with the advice they need to prioritize their vulnerabilities. Every vulnerability scanning vendor will proclaim their ability to prioritize the identified vulnerabilities.

Third-party prioritization methodology can’t be effectively applied across all organizations. Each organization is too unique with different constraints. No tool or service can account for these variables.

Equation to find 'Vulnerability Priority'.

When patching is not possible, other options exist: configuration changes (hardening), defense-in-depth, compensating controls, and even elevated security monitoring are possible options.

Info-Tech Insight

Vulnerability management is not only patch management. Patching is only one aspect.

What is vulnerability management?

It’s more than just patching.

  • Vulnerability management is the regular and ongoing practice of scanning an operating environment to uncover vulnerabilities. These vulnerabilities can be outdated applications, unpatched operating systems and software, open ports, obsolete hardware, or any combination of these.
  • The scanning and detection of vulnerabilities is the first step. Planning and executing of remediation is next, along with the approach, prioritized sequence of events, and timing.
  • A vendor-supplied software patch or firmware update is often the easy answer, however, this is not always a viable solution. What if you can’t patch in a timely fashion? What if patching is not possible as it will break the application and bring down operations? What if no patch exists due to the age of the application or operating platform?

“Most organizations do not have a formal process for vulnerability management.” (Morey Haber, VP of Technology, BeyondTrust, 2016)

Effective vulnerability management

It’s not easy, but it’s much harder without a process in place.
  • Effective vulnerability management requires a formal process for organizations to follow; without one, vulnerabilities are dealt with in an ad hoc fashion.
  • Patching isn’t the only solution, but it’s the one that often draws focus.
  • Responsibilities for the different aspects of vulnerability management are often unclear, such as for testing, remediation, and implementation.
  • Identifying new threats without proper vulnerability scanning tools can be a near-impossible task.
  • Determining which vulnerabilities are most urgent can be an inconsistent process, increasing the organizational risk.
  • Measuring the effectiveness of your vulnerability remediation activities can help you better manage resources in SecOps and ITOps. Your staff will be spending the appropriate effort on vulnerabilities that warrant that level of attention.

You’re not just doing this for yourself. It’s also for your auditors.

Many compliance and regulatory obligations require organizations to have thorough documentation of their vulnerability management practices.
