cyberstrikeus CIS Ubuntu Linux 16.04 LTS Benchmark v2.0.0 - 1.6.1.4
Profile Applicability
- Level 2 - Server
- Level 2 - Workstation
Description
AppArmor profiles define what resources applications are able to access.
Rationale
Security configuration requirements vary from site to site. Some sites may mandate a policy that is stricter than the default policy, which is perfectly acceptable. This item is intended to ensure that any policies that exist on the system are activated.
Audit Procedure
Command Line
Run the following commands and verify that profiles are loaded and are not in complain mode:
apparmor_status | grep profiles
Review output and ensure that profiles are loaded, and in enforce mode:
34 profiles are loaded.
34 profiles are in enforce mode.
0 profiles are in complain mode.
2 processes have profiles defined.
Run the following command and verify that no processes are unconfined:
apparmor_status | grep processes
Review the output and ensure no processes are unconfined:
2 processes have profiles defined.
2 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
Expected Result
All profiles should be in enforce mode with 0 profiles in complain mode. No processes should be unconfined.
Remediation
Command Line
Run the following command to set all profiles to enforce mode:
aa-enforce /etc/apparmor.d/*
Note: Any unconfined processes may need to have a profile created or activated for them and then be restarted.
Default Value
Not applicable.
References
None.
