Chapter: Vulnerability Management
Vulnerability management is a continuous cybersecurity process that includes identifying, assessing, prioritizing, and remediating security vulnerabilities in systems, applications, and networks. Proper vulnerability handling ensures that organizations minimize security risks while maintaining operational efficiency.
1. Compensating Control
Definition:
A compensating control is a security measure implemented to mitigate a risk when a primary security control cannot be applied due to operational, technical, or business constraints. It acts as a temporary or alternative measure to reduce the likelihood or impact of a security threat.
Key Characteristics of Compensating Controls:
- Temporary or Alternative: Used when a recommended security control (e.g., patching) cannot be implemented immediately.
- Risk Reduction: While it may not eliminate the risk entirely, it lowers the risk to an acceptable level.
- Requires Justification & Documentation: Organizations must provide a clear justification for why compensating controls are used.
- Regulatory Compliance: Many security frameworks (PCI DSS, NIST, ISO 27001) allow compensating controls when strict security requirements cannot be met.
