This should occur on a regular basis, ideally with scans scheduled to occur automatically at some set time interval. Where appropriate, some vulnerabilities might also be identified using code scanning tools, such as a SAST (Static Application Security Testing) tool to check the codebase for obvious vulnerabilities or SCA (Software Composition Analysis) tool identify vulnerable dependencies used by the application. In some cases none of the above options will be viable for the application and, in this case, direct human assessment of host configuration and manual code reviews might be the only suitable option for assessing the security posture of the legacy application.\n\nPatch Management: Where possible, apply patches raised by the tools described above. Patching efforts should be prioritized on the basis of the severity of the vulnerability and whether the vulnerability has a published CVE (Common Vulnerabilities and Exposures) and/or a publicly listed exploit. In circumstances where patching is not practically possible for the legacy application, consider applying additional restrictions to the application/affected components as noted in the section on Authentication/Authorization.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
