courier_selinux(8)   courier SELinux Policy documentation   courier_selinux(8)

NAME
       courier_selinux	-  Security Enhanced Linux Policy for the courier pro‐
       cesses

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

NSSWITCH DOMAIN
       If  you	want  to  allow	 users	to  login  using  a sssd serve for the
       courier_authdaemon_t, you must turn on the  authlogin_nsswitch_use_ldap
       boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       courier_authdaemon_t, you must turn on the allow_kerberos boolean.

       setsebool -P allow_kerberos 1

       If you want to allow system to run with	NI  for	 the  courier_authdae‐
       mon_t, you must turn on the allow_ypbind boolean.

       setsebool -P allow_ypbind 1

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

       The following file types are defined for courier:

       courier_authdaemon_exec_t

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

       courier_etc_t

       -  Set  files with the courier_etc_t type, if you want to store courier
       files in the /etc directories.

       Paths:
	    /usr/lib/courier/rootcerts(/.*)?, /etc/courier(/.*)?

       courier_exec_t

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

       Paths:
	    /usr/sbin/courierlogger,		  /usr/lib/courier/courier/.*,
	    /usr/sbin/courierldapaliasd

       courier_pcp_exec_t

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

       courier_pop_exec_t

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

       Paths:
	    /usr/lib/courier/imapd,	/usr/lib/courier/courier/courierpop.*,
	    /usr/lib/courier/pop3d,	   /usr/lib/courier/courier/imaplogin,
	    /usr/bin/imapd

       courier_spool_t

       - Set files with the courier_spool_t type, if you  want	to  store  the
       courier files under the /var/spool directory.

       Paths:
	    /var/spool/authdaemon(/.*)?, /var/spool/courier(/.*)?

       courier_sqwebmail_exec_t

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

       courier_tcpd_exec_t

       - Set files with the courier_tcpd_exec_t type, if you want  to  transi‐
       tion an executable to the courier_tcpd_t domain.

       courier_var_lib_t

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

       courier_var_run_t

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

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanantly change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  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
       courier policy is very flexible allowing users to setup	their  courier
       processes in as secure a method as possible.

       The following process types are defined for courier:

       courier_sqwebmail_t, courier_tcpd_t, courier_authdaemon_t, courier_pcp_t, courier_pop_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.
