NAME

6       fail2ban_selinux - Security Enhanced Linux Policy for the fail2ban pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  fail2ban  processes  via  flexible
11       mandatory access control.
12
13       The  fail2ban  processes  execute with the fail2ban_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 fail2ban_t
20
21
22

ENTRYPOINTS

24       The fail2ban_t SELinux type can be entered via the fail2ban_exec_t file
25       type.
26
27       The default entrypoint paths for the fail2ban_t domain are the  follow‐
28       ing:
29
30       /usr/bin/fail2ban, /usr/bin/fail2ban-server
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       fail2ban policy is very flexible allowing users to setup their fail2ban
40       processes in as secure a method as possible.
41
42       The following process types are defined for fail2ban:
43
44       fail2ban_t
45
46       Note: semanage permissive -a fail2ban_t can be used to make the process
47       type  fail2ban_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       fail2ban policy is extremely flexible and  has  several  booleans  that
55       allow  you  to manipulate the policy and run fail2ban with the tightest
56       access possible.

MANAGED FILES

154       The  SELinux  process type fail2ban_t can manage files labeled with the
155       following file types.  The paths listed are the default paths for these
156       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

232       SELinux requires files to have an extended attribute to define the file
233       type.
234
235       You can see the context of a file using the -Z option to ls
236
237       Policy governs the access  confined  processes  have  to  these  files.
238       SELinux  fail2ban policy is very flexible allowing users to setup their
239       fail2ban processes in as secure a method as possible.
240
241       STANDARD FILE CONTEXT
242
243       SELinux defines the file context types for the fail2ban, if you  wanted
244       to store files with these types in a diffent paths, you need to execute
245       the semanage command  to  sepecify  alternate  labeling  and  then  use
246       restorecon to put the labels on disk.
247
248       semanage   fcontext   -a  -t  fail2ban_var_run_t  '/srv/myfail2ban_con‐
249       tent(/.*)?'
250       restorecon -R -v /srv/myfail2ban_content
251
252       Note: SELinux often uses regular expressions  to  specify  labels  that
253       match multiple files.
254
255       The following file types are defined for fail2ban:
256
257
258
259       fail2ban_exec_t
260
261       - Set files with the fail2ban_exec_t type, if you want to transition an
262       executable to the fail2ban_t domain.
263
264
265       Paths:
266            /usr/bin/fail2ban, /usr/bin/fail2ban-server
267
268
269       fail2ban_initrc_exec_t
270
271       - Set files with the fail2ban_initrc_exec_t type, if you want to  tran‐
272       sition an executable to the fail2ban_initrc_t domain.
273
274
275
276       fail2ban_log_t
277
278       - Set files with the fail2ban_log_t type, if you want to treat the data
279       as fail2ban log data, usually stored under the /var/log directory.
280
281
282
283       fail2ban_tmp_t
284
285       - Set files with the fail2ban_tmp_t type, if you want to store fail2ban
286       temporary files in the /tmp directories.
287
288
289
290       fail2ban_var_lib_t
291
292       -  Set files with the fail2ban_var_lib_t type, if you want to store the
293       fail2ban files under the /var/lib directory.
294
295
296
297       fail2ban_var_run_t
298
299       - Set files with the fail2ban_var_run_t type, if you want to store  the
300       fail2ban files under the /run or /var/run directory.
301
302
303
304       Note:  File context can be temporarily modified with the chcon command.
305       If you want to permanently change the file context you need to use  the
306       semanage fcontext command.  This will modify the SELinux labeling data‐
307       base.  You will need to use restorecon to apply the labels.
308
309

COMMANDS

311       semanage fcontext can also be used to manipulate default  file  context
312       mappings.
313
314       semanage  permissive  can  also  be used to manipulate whether or not a
315       process type is permissive.
316
317       semanage module can also be used to enable/disable/install/remove  pol‐
318       icy modules.
319
320       semanage boolean can also be used to manipulate the booleans
321
322
323       system-config-selinux is a GUI tool available to customize SELinux pol‐
324       icy settings.
