NAME

6       denyhosts_selinux  -  Security  Enhanced Linux Policy for the denyhosts
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the denyhosts  processes  via  flexible
11       mandatory access control.
12
13       The  denyhosts processes execute with the denyhosts_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 denyhosts_t
20
21
22

ENTRYPOINTS

24       The  denyhosts_t  SELinux  type can be entered via the denyhosts_exec_t
25       file type.
26
27       The default entrypoint paths for the denyhosts_t domain are the follow‐
28       ing:
29
30       /usr/bin/denyhosts.py
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       denyhosts  policy  is very flexible allowing users to setup their deny‐
40       hosts processes in as secure a method as possible.
41
42       The following process types are defined for denyhosts:
43
44       denyhosts_t
45
46       Note: semanage permissive -a  denyhosts_t  can  be  used  to  make  the
47       process  type  denyhosts_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

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

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

FILE CONTEXTS

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

COMMANDS

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