Risk-Based Vulnerability Management

Risk-Based Vulnerability Management (RBVM) is an approach that prioritizes vulnerabilities based on the potential risk they pose to the organization. This method ensures that resources are allocated effectively to mitigate the most critical vulnerabilities first.

• Vulnerability: A weakness in a system that can be exploited by threats.
• Risk: The potential for loss or damage when a threat exploits a vulnerability.
• Threat: Any circumstance that has the potential to exploit a vulnerability.
• Impact: The degree of damage that a threat could cause if it exploits a vulnerability.
• Likelihood: The probability that a threat will exploit a given vulnerability.

3.1 Identify Assets

Catalog all assets in your environment. This includes servers, applications, databases, and network devices.

3.2 Identify Vulnerabilities

Use tools like Qualys, Nessus, or OpenVAS to identify vulnerabilities.

3.3 Assess Risk

Evaluate the risk associated with each vulnerability by considering both the impact and likelihood:

risk = impact * likelihood

3.4 Prioritize Vulnerabilities

Use risk scores to prioritize vulnerabilities. Focus on those with the highest scores.

3.5 Remediation

Develop and execute remediation plans for the highest priority vulnerabilities.

1. Integrate RBVM into your continuous integration/continuous deployment (CI/CD) pipeline.
2. Educate your team about the importance of vulnerability management.
3. Regularly review and update your risk assessment criteria.
4. Utilize automation to streamline vulnerability scanning and reporting.
5. Implement a feedback loop to continuously improve your vulnerability management process.
