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 the ePO server console System Tree, select "My Organization". Select the "Systems" tab. To show all systems in the System Tree, select "This Group and All Subgroups" from the "Preset:" drop-down list. From the list of systems, locate the asset representing the Linux system being reviewed. Click on the system to open the System Information page. Click on Actions >> Agent >> Modify Policies on a Single System. From the "Product:" drop-down list, select "VirusScan Enterprise for Linux 1.9.x/2.0.x". From the "Policy" column, click on the policy for the "On-Access Scanning Policy". In the "Detections" tab, next to "What not to scan:", verify the only entries for the "Select files and directories to be excluded from virus scanning" field are those below: Under "Paths Excluded From Scanning", verify no entries exist other than the allowed default paths referenced below: /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 default paths referenced above are present in the "What not to scan:" setting for the "Select files and directories to be excluded from virus scanning" field, verify the exclusion of those files and directories has been formally documented by the System Administrator and has been approved by the ISSO/ISSM. If any entries other than the default paths referenced above are present in the "What not to scan:" setting for the "Select files and directories to be excluded from virus scanning" field, and those files and directories have not been formally documented by the System Administrator and approved by the ISSO/ISSM, this is a finding. If any entries other than the default paths referenced above are present in the "What not to scan:" setting for the "Select files and directories to be excluded from virus scanning" field, and those files and directories have been formally documented by the System Administrator and approved by the ISSO/ISSM, this is not a finding.
