Vulnerability discussion

Virus scanning software can be used to protect a system from penetration from computer viruses and to limit their spread through intermediate systems. Virus scanning software is available to DoD on the JTF-GNO web site.The virus scanning software should be configured to perform scans dynamically on accessed files. If this capability is not available, the system must be configured to scan, at a minimum, all altered files on the system on a daily basis.If the system processes inbound SMTP mail, the virus scanner must be configured to scan all received mail.

Check content

Check for the existence of the command line scan tool to be executed daily in the cron file. Additional tools specific for each operating system are also available and will have to be manually reviewed if installed. In addition, the definitions file should not be older than seven (7) days. Check if uvscan is scheduled to run. # grep uvscan /var/spool/cron/crontabs/* The following example command assumes the use of the McAfee virus tool. Perform the following command to ensure the virus definition signature files are not older than seven (7) days. # ls -la avvclean.dat avvnames.dat avvscan.dat If a virus scanner is not being run daily or the virus definitions are older than seven (7) days, this is a finding.

Fix text

Install a virus scan tool. Ensure the virus signature definition files are no older than seven (7) days. Ensure the command line virus scan tool is run on a regular basis using a utility, such as cron.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
