Vulnerability discussion

Anti-virus software is the most commonly used technical control for malware threat mitigation. Real-time scanning of files as they are read from disk is a crucial first line of defense from malware attacks.

Check content

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 "Configure", select "On-Access Settings". Under "Anti-virus Actions", verify the "Block" radio button is selected for "Action if an error occurs during scanning". If the "Block" radio button is not selected for "Action if an error occurs during scanning", 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, navigate to /var/opt/NAI/LinuxShield/etc. Enter the command "grep "ScanAction" nailsd.cfg -A 5" nailsd.cfg" If the response given for "nailsd.profile.OAS.action.error" is not "Block", this is a finding.

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.
