Vulnerabilities are flaws attackers can exploit to access systems or data; timely patching, isolation, and least privilege reduce the impact.

Background for this topic.
A vulnerability is a weakness in a system’s design, code, configuration, or operating process that could allow an attacker to violate a security requirement. It may affect software, hardware, networks, cloud services, or exposed interfaces, and is not automatically exploitable: practical risk depends on factors such as exposure, required privileges, available attack paths, and existing controls. Outcomes can include unauthorized access, information disclosure, code execution, or disruption of service.
Effective vulnerability management combines accurate asset inventory with code review, security testing, scanning, and trusted vulnerability intelligence. Organizations should prioritize weaknesses affecting reachable, business-critical systems—especially when exploitation is known or requires little access—then patch or otherwise mitigate them and verify the fix. Where patching is delayed, controls such as disabling an exposed feature, restricting network access, or strengthening authentication can reduce the attack surface. Records should preserve affected versions, risk decisions, remediation owners, and validation results.
