Description
Virus scanning software can be used to protect a system from penetration from computer viruses and to limit their spread through intermediate systems. The virus scanning software should be configured to check for software and virus definition updates with a frequency no longer than seven days. If a manual process is required to update the virus scan software or definitions, it must be documented with the Information System Security Officer (ISSO).
