NAME cyrus_selinux - Security Enhanced Linux Policy for the cyrus processes

DESCRIPTION SELinux Linux secures cyrus (Cyrus is an IMAP service intended to be run on sealed servers) processes via flexible mandatory access control.

FILE CONTEXTS 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 ls

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

The following file types are defined for cyrus:

cyrus_exec_t

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

cyrus_initrc_exec_t

- Set files with the cyrus_initrc_exec_t type, if you want to transi- tion an executable to the cyrus_initrc_t domain.

cyrus_keytab_t

- Set files with the cyrus_keytab_t type, if you want to treat the files as kerberos keytab files.

cyrus_tmp_t

- Set files with the cyrus_tmp_t type, if you want to store cyrus tem- porary files in the /tmp directories.

cyrus_var_lib_t

- Set files with the cyrus_var_lib_t type, if you want to store the cyrus files under the /var/lib directory.

cyrus_var_run_t

- Set files with the cyrus_var_run_t type, if you want to store the cyrus files under the /run directory.

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.

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 ps

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

The following process types are defined for cyrus:

cyrus_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

COMMANDS 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 pol- icy modules.

system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
