Description
Anti-virus signature files are updated almost daily by anti-virus software vendors. These files are made available to anti-virus clients as they are published. Keeping virus signature files as current as possible is vital to the security of any system. By configuring a system to attempt an anti-virus update on a daily basis, the system is ensured of maintaining an anti-virus signature age of 7 days or less. If the update attempt were to be configured for only once a week, and that attempt failed, the system would be immediately out of date.

From a desktop browser window, connect to the McAfee VirusScan Enterprise for Linux (VSEL) Monitor (WEB interface) of the Linux system being reviewed and logon with the nails user account. In the VSEL WEB Monitor, under "View", select "Host Summary". In the "Host Summary", verify the "DAT Date:" is within the last 7 days. If the "DAT Date:" is not within the last 7 days, this is a finding. To validate without the Web interface, access the Linux system being reviewed, either at the console or by a SSH connection. At the command line, enter the command "ls -lt /opt/NAI/LinuxShield/engine/dat". The command will return a listing of the avvclean.dat, avvnames.dat and avvscan.dat files. If their respective file dates are not within the last 7 days, this is a finding.
