NAME

6       gssproxy_selinux - Security Enhanced Linux Policy for the gssproxy pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The gssproxy_t SELinux type can be entered via the gssproxy_exec_t file
25       type.
26
27       The default entrypoint paths for the gssproxy_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/gssproxy
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       gssproxy policy is very flexible allowing users to setup their gssproxy
40       processes in as secure a method as possible.
41
42       The following process types are defined for gssproxy:
43
44       gssproxy_t
45
46       Note: semanage permissive -a gssproxy_t can be used to make the process
47       type  gssproxy_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

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

FILE CONTEXTS

258       SELinux requires files to have an extended attribute to define the file
259       type.
260
261       You can see the context of a file using the -Z option to ls
262
263       Policy  governs  the  access  confined  processes  have to these files.
264       SELinux gssproxy policy is very flexible allowing users to setup  their
265       gssproxy processes in as secure a method as possible.
266
267       STANDARD FILE CONTEXT
268
269       SELinux  defines the file context types for the gssproxy, if you wanted
270       to store files with these types in a diffent paths, you need to execute
271       the  semanage  command  to  sepecify  alternate  labeling  and then use
272       restorecon to put the labels on disk.
273
274       semanage  fcontext  -a  -t   gssproxy_var_run_t   '/srv/mygssproxy_con‐
275       tent(/.*)?'
276       restorecon -R -v /srv/mygssproxy_content
277
278       Note:  SELinux  often  uses  regular expressions to specify labels that
279       match multiple files.
280
281       The following file types are defined for gssproxy:
282
283
284
285       gssproxy_exec_t
286
287       - Set files with the gssproxy_exec_t type, if you want to transition an
288       executable to the gssproxy_t domain.
289
290
291
292       gssproxy_unit_file_t
293
294       -  Set  files  with the gssproxy_unit_file_t type, if you want to treat
295       the files as gssproxy unit content.
296
297
298
299       gssproxy_var_lib_t
300
301       - Set files with the gssproxy_var_lib_t type, if you want to store  the
302       gssproxy files under the /var/lib directory.
303
304
305
306       gssproxy_var_run_t
307
308       -  Set files with the gssproxy_var_run_t type, if you want to store the
309       gssproxy files under the /run or /var/run directory.
310
311
312       Paths:
313            /var/run/gssproxy.pid, /var/run/gssproxy.sock
314
315
316       Note: File context can be temporarily modified with the chcon  command.
317       If  you want to permanently change the file context you need to use the
318       semanage fcontext command.  This will modify the SELinux labeling data‐
319       base.  You will need to use restorecon to apply the labels.
320
321

COMMANDS

323       semanage  fcontext  can also be used to manipulate default file context
324       mappings.
325
326       semanage permissive can also be used to manipulate  whether  or  not  a
327       process type is permissive.
328
329       semanage  module can also be used to enable/disable/install/remove pol‐
330       icy modules.
331
332       semanage boolean can also be used to manipulate the booleans
333
334
335       system-config-selinux is a GUI tool available to customize SELinux pol‐
336       icy settings.
