Check Contents

Identify any unsigned applications that have been installed on the system:
/usr/sbin/system_profiler SPApplicationsDataType | /usr/bin/grep -B 3 -A 4 -e "Obtained from: Unknown" | /usr/bin/grep -v -e "Location: /Library/Application Support/Script Editor/Templates" -e "Location: /System/Library/" | /usr/bin/awk -F "Location: " '{print $2}' | /usr/bin/sort -u

If any results are returned and is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding.

Verify only applications with a valid digital signature are allowed to run:
/usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep -E '(EnableAssessment | AllowIdentifiedDevelopers)'

If the return is null, or is not:
AllowIdentifiedDevelopers = 1;
EnableAssessment = 1;
This is a finding.
