Security Enhanced Linux Policy for the sftpd processes


Security-Enhanced Linux secures the sftpd processes via flexible mandatory access control.

The sftpd processes execute with the sftpd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep sftpd_t

Process Types

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to psbP

Policy governs the access confined processes have to files. SELinux sftpd policy is very flexible allowing users to setup their sftpd processes in as secure a method as possible.

The following process types are defined for sftpd:


Note: semanage permissive -a sftpd_t can be used to make the process type sftpd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.


SELinux policy is customizable based on least access required.  sftpd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sftpd with the tightest access possible.

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 fcontext can also be used to manipulate default file context mappings.

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.
