setkey_selinux - Man Page

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

The setkey processes execute with the setkey_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 setkey_t

The setkey_t SELinux type can be entered via the setkey_exec_t file type.

The default entrypoint paths for the setkey_t domain are the following:

/usr/bin/setkey

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 setkey policy is very flexible allowing users to setup their setkey processes in as secure a method as possible.

The following process types are defined for setkey:

setkey_t

Note: semanage permissive -a setkey_t can be used to make the process type setkey_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.  setkey policy is extremely flexible and has several booleans that allow you to manipulate the policy and run setkey 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

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to lsbP

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the setkey, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t setkey_exec_t '/srv/setkey/content(/.*)?'
restorecon -R -v /srv/mysetkey_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for setkey:

setkey_exec_t

- Set files with the setkey_exec_t type, if you want to transition an executable to the setkey_t domain.

Note: File context can be temporarily modified with the chcon command.  If you want to permanently change the file context you need to use the semanage fcontext command.  This will modify the SELinux labeling database.  You will need to use restorecon to apply the labels.

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.
