When scanning for malware, excluding specific files will increase the risk of a malware-infected file going undetected. By configuring anti-virus software without any exclusions, the scanner has a higher success rate at detecting and eradicating malware.
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 "Paths Excluded From Scanning", verify no entries exist other than the following: /var/log /_admin/Manage_NSS /mnt/system/log /media/nss/.*/(\._NETWARE|\._ADMIN) /.*\.(vmdk|VMDK|dbl|DBL|ctl|CTL|log|LOG|jar|JAR|war|WAR|dtx|DTX|dbf|DBF|frm|FRM|myd|MYD|myi|MYI|rdo|RDO|arc|ARC) /cgroup /dev /proc /selinux /sys If any entries other than the above referenced paths are present in the "Paths Excluded From Scanning" field, verify the exclusion of those files and paths have been formally documented by the System Administrator and has been approved by the ISSO/ISSM. If they have not been formally documented by the System Administrator and approved by the ISSO/ISSM, this is a finding. If they have not been formally documented by the System Administrator and approved by the ISSO/ISSM but are validated as being scanned within the regularly scheduled scan, this is a finding but can be dropped to a CAT 3. 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 "exclude-path" nailsd.cfg -A 5" If the response given is: "nailsd.profile.OAS.filter.varlog.type: exclude-path" and "nailsd.profile.OAS.filter.varlog.path:" includes anything other than the above paths", this is a finding.
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". Click "Edit". Under "Paths Excluded From Scanning", remove all entries other than the default "/var/log". Click "Apply".
Lavender hyperlinks in small type off to the right (of CSS

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
