Australian Information Security Manual ISM-0917: Handling malicious code infections

When malicious code is detected, the following steps are taken to handle the infection: - the infected systems are isolated - all previously connected media used in the period leading up to the infection are scanned for signs of infection and isolated if necessary - antivirus applications are used to remove the infection from infected systems and media - if the infection cannot be reliably removed, systems are restored from a known good backup or rebuilt.

What else in your programme already covers this

This control maps to 5 controls across 3 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
