NAME
       comsat_selinux  -  Security  Enhanced  Linux Policy for the comsat pro‐
       cesses

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

       The  comsat  processes  execute with the comsat_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 comsat_t

ENTRYPOINTS
       The  comsat_t  SELinux  type  can be entered via the comsat_exec_t file
       type.

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

       /usr/sbin/in.comsat

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

       The following process types are defined for comsat:

       comsat_t

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

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

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       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

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If  you	want  to allow confined applications to run with kerberos, you
       must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with	NIS,  you  must	 turn  on  the
       nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If  you	want to allow confined applications to use nscd shared memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap rather then using a sssd server for the comsat_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
       comsat_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

PORT TYPES
       SELinux defines port types to represent TCP and UDP ports.

       You  can	 see  the  types associated with a port by using the following
       command:

       semanage port -l

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

       The following port types are defined for comsat:

       comsat_port_t

       Default Defined Ports:
		 udp 512

MANAGED FILES
       The SELinux process type comsat_t can manage  files  labeled  with  the
       following file types.  The paths listed are the default paths for these
       file types.  Note the processes UID still need to have DAC permissions.

       comsat_tmp_t

       comsat_var_run_t

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

       STANDARD FILE CONTEXT

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

       semanage fcontext -a -t comsat_exec_t '/srv/comsat/content(/.*)?'
       restorecon -R -v /srv/mycomsat_content

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

       The following file types are defined for comsat:

       comsat_exec_t

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

       comsat_tmp_t

       - Set files with the comsat_tmp_t type, if you  want  to	 store	comsat
       temporary files in the /tmp directories.

       comsat_var_run_t

       -  Set  files  with the comsat_var_run_t type, if you want to store the
       comsat files under the /run or /var/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 data‐
       base.  You will need to use restorecon to apply the labels.

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.

       semanage port can also be used to manipulate the port definitions

       semanage boolean can also be used to manipulate the booleans

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