How to Prioritize Security Vulnerabilities for Maximum Efficiency
In today’s fast-paced development environment, security vulnerabilities demand a substantial portion of developers’ time. As the number of vulnerabilities continues to grow, organizations must rethink how they classify and prioritize them. Rather than focusing solely on theoretical severity, a more effective approach is to assess whether a vulnerability is truly attackable.
The Challenge of Security Remediations
Security remediations, particularly Sev-1 vulnerabilities, often slow down development processes. In 2021, approximately 35% of Common Vulnerabilities and Exposures (CVEs) were classified as critical (Sev-1). With over 18,000 vulnerabilities reported in 2022 alone, the flood of security alerts has become overwhelming. This influx of threats can sap developer productivity, diverting attention away from new features or software updates.
Interestingly, not all Sev-1 vulnerabilities are created equal. A critical vulnerability in one organization might be irrelevant in another, depending on the context in which it appears. For example, a vulnerability in a logging component might pose a significant risk in a customer-facing app but be largely harmless in a non-production environment. As a result, developers should reconsider the conventional approach of prioritizing all Sev-1s and instead evaluate vulnerabilities based on their true attackability.
Why Attackability Matters
The core question developers should ask is: Is this vulnerability attackable? This shift in mindset helps distinguish between vulnerabilities that pose a real threat and those that, due to application structure, are effectively unreachable. By focusing on attackability, development teams can more efficiently allocate resources and address actual security risks while minimizing unnecessary disruptions.
Step 1: Refactor Criticality Rankings to Include Attackability
Current criticality ratings often rely on theoretical risks, which may not apply to every organization. For example, a remote takeover exploit might be classified as Sev-1, but the actual risk depends on the application architecture and security layers in place. By evaluating whether a vulnerability can actually affect critical systems, AppSec teams can make more informed decisions. This can be done manually through code path analysis or with automated tools that assess the entire application for potential attack paths.
Step 2: Prioritize Based on Attackability
Once attackability is factored in, the next step is to adjust issue prioritization. Rather than assigning priority based solely on severity, add a simple flag (e.g., “attackable: yes/no”) in vulnerability management systems. This can drastically reduce the workload, as research has shown that many Sev-1 vulnerabilities are not actually exploitable in typical organizational setups. Reducing the vulnerability queue by up to 90% makes it easier for security teams to focus on the most critical threats, streamlining the remediation process.
Step 3: Determine the Best Remediation Path
After confirming that a vulnerability is attackable, the next step is deciding how to remediate it. There are various remediation options, including sanitizing the input, writing new code fixes, or reconfiguring security controls. While fixing the underlying code is often the most robust solution, it’s important to balance this with productivity concerns. Continuous code updates can introduce instability, so it’s essential to carefully evaluate the best course of action.
Step 4: Continuously Monitor for Attackability Drift Security Vulnerabilities
Just as security drift occurs when network and API changes weaken security controls, vulnerabilities can also shift in attackability over time. For instance, changing an API structure or introducing new business logic can inadvertently open new attack vectors. To mitigate this risk, continuous security scanning is essential. Automated security testing solutions must be efficient and capable of scanning complex codebases without introducing delays in the development pipeline.
In addition to maintaining scan efficiency, these tools should also detect vulnerabilities that may have been previously deemed irrelevant but have since become attackable due to architectural changes.
Step 5: Redefine Metrics to Focus on Attackability Security Vulnerabilities
Finally, it’s crucial for security and development teams to align on the new approach. This may require educating stakeholders on the revised remediation process and how it impacts reported vulnerabilities. Key metrics should reflect the focus on attackable vulnerabilities, rather than raw severity numbers. By tracking progress through metrics that emphasize attackability, teams can demonstrate improved security posture, faster shipping of new features, and better developer satisfaction.
Conclusion for Prioritizing Security Vulnerabilities
As the number of vulnerabilities continues to rise, organizations must adopt smarter strategies to manage them. Focusing on attackability rather than blindly fixing every Sev-1 vulnerability enables security teams and developers to work more efficiently. By prioritizing real risks and fostering collaboration, companies can achieve stronger security without sacrificing development velocity.
