NAME

6       pesign_selinux  -  Security  Enhanced  Linux Policy for the pesign pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  pesign  processes  via  flexible
11       mandatory access control.
12
13       The  pesign  processes  execute with the pesign_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep pesign_t
20
21
22

ENTRYPOINTS

24       The  pesign_t  SELinux  type  can be entered via the pesign_exec_t file
25       type.
26
27       The default entrypoint paths for the pesign_t domain are the following:
28
29       /usr/bin/pesign
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       pesign policy is very flexible allowing users  to  setup  their  pesign
39       processes in as secure a method as possible.
40
41       The following process types are defined for pesign:
42
43       pesign_t
44
45       Note:  semanage  permissive -a pesign_t can be used to make the process
46       type pesign_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

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

MANAGED FILES

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

FILE CONTEXTS

218       SELinux requires files to have an extended attribute to define the file
219       type.
220
221       You can see the context of a file using the -Z option to ls
222
223       Policy  governs  the  access  confined  processes  have to these files.
224       SELinux pesign policy is very flexible allowing users  to  setup  their
225       pesign processes in as secure a method as possible.
226
227       EQUIVALENCE DIRECTORIES
228
229
230       pesign  policy  stores  data with multiple different file context types
231       under the /var/run/pesign directory.  If you would like  to  store  the
232       data  in a different directory you can use the semanage command to cre‐
233       ate an equivalence mapping.  If you wanted to store this data under the
234       /srv dirctory you would execute the following command:
235
236       semanage fcontext -a -e /var/run/pesign /srv/pesign
237       restorecon -R -v /srv/pesign
238
239       STANDARD FILE CONTEXT
240
241       SELinux defines the file context types for the pesign, if you wanted to
242       store files with these types in a diffent paths, you  need  to  execute
243       the  semanage  command  to  sepecify  alternate  labeling  and then use
244       restorecon to put the labels on disk.
245
246       semanage fcontext -a -t pesign_var_run_t '/srv/mypesign_content(/.*)?'
247       restorecon -R -v /srv/mypesign_content
248
249       Note: SELinux often uses regular expressions  to  specify  labels  that
250       match multiple files.
251
252       The following file types are defined for pesign:
253
254
255
256       pesign_exec_t
257
258       -  Set  files with the pesign_exec_t type, if you want to transition an
259       executable to the pesign_t domain.
260
261
262
263       pesign_tmp_t
264
265       - Set files with the pesign_tmp_t type, if you  want  to  store  pesign
266       temporary files in the /tmp directories.
267
268
269
270       pesign_unit_file_t
271
272       -  Set files with the pesign_unit_file_t type, if you want to treat the
273       files as pesign unit content.
274
275
276
277       pesign_var_run_t
278
279       - Set files with the pesign_var_run_t type, if you want  to  store  the
280       pesign files under the /run or /var/run directory.
281
282
283       Paths:
284            /var/run/pesign(/.*)?, /var/run/pesign.pid
285
286
287       Note:  File context can be temporarily modified with the chcon command.
288       If you want to permanently change the file context you need to use  the
289       semanage fcontext command.  This will modify the SELinux labeling data‐
290       base.  You will need to use restorecon to apply the labels.
291
292

COMMANDS

294       semanage fcontext can also be used to manipulate default  file  context
295       mappings.
296
297       semanage  permissive  can  also  be used to manipulate whether or not a
298       process type is permissive.
299
300       semanage module can also be used to enable/disable/install/remove  pol‐
301       icy modules.
302
303       semanage boolean can also be used to manipulate the booleans
304
305
306       system-config-selinux is a GUI tool available to customize SELinux pol‐
307       icy settings.
