Vulnerability mitigation is typically considered a temporary or interim solution. While mitigation measures can reduce the immediate risk associated with vulnerabilities, they may not provide a permanent fix . Organizations should aim to prioritize and plan for complete vulnerability remediation whenever feasible and allocate resources accordingly.

Remediation fully removes a vulnerability by fixing its root cause — through a patch , code fix , or system replacement. Mitigation reduces the risk of exploitation without removing the flaw itself, using controls like network segmentation or access restrictions.

Mitigation uses compensating controls, such as WAF rules, to reduce the likelihood of exploitation until a fix is viable, while patching is a specific remediation technique that involves applying vendor-supplied code updates.

web:www.zafran.io
Mitigation is the control implemented or the action taken to reduce the impact or likelihood of a vulnerability or exposure being exploited before a fix is available or applied. Remediation is the resolution of the vulnerability or exposure which is completed typically through applying patches, updates, or correcting misconfigurations.
