Vulnerability discussion

When scanning for malware, excluding specific file types will increase the risk of a malware-infected file going undetected. By configuring anti-virus software to scan all file types, the scanner has a higher success rate at detecting and eradicating malware.

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 "Extension Base Scanning", verify the "Scan all files" radio button is selected. If the radio button "Scan all files" is not selected, 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 "allFiles" nailsd.cfg" If the response given is "nailsd.profile.OAS.allFiles: false" or is "nailsd.profile.OAS.allFiles: true" with a preceding #, 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.
