Handling and containing malicious code infections

Official control wording

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.
