Security-Enhanced Linux secures the anon_sftpd processes via flexible mandatory access control.
The anon_sftpd processes execute with the anon_sftpd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep anon_sftpd_t
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux anon_sftpd policy is very flexible allowing users to setup their anon_sftpd processes in as secure a method as possible.
The following process types are defined for anon_sftpd:
Note: semanage permissive -a anon_sftpd_t can be used to make the process type anon_sftpd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
