NAME

6       foghorn_selinux  -  Security Enhanced Linux Policy for the foghorn pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  foghorn  processes  via  flexible
11       mandatory access control.
12
13       The  foghorn processes execute with the foghorn_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 foghorn_t
20
21
22

ENTRYPOINTS

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

180       following file types.  The paths listed are the default paths for these
181       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

239       SELinux requires files to have an extended attribute to define the file
240       type.
241
242       You can see the context of a file using the -Z option to ls
243
244       Policy  governs  the  access  confined  processes  have to these files.
245       SELinux foghorn policy is very flexible allowing users to  setup  their
246       foghorn processes in as secure a method as possible.
247
248       STANDARD FILE CONTEXT
249
250       SELinux  defines  the file context types for the foghorn, if you wanted
251       to store files with these types in a diffent paths, you need to execute
252       the  semanage  command  to  sepecify  alternate  labeling  and then use
253       restorecon to put the labels on disk.
254
255       semanage  fcontext   -a   -t   foghorn_var_run_t   '/srv/myfoghorn_con‐
256       tent(/.*)?'
257       restorecon -R -v /srv/myfoghorn_content
258
259       Note:  SELinux  often  uses  regular expressions to specify labels that
260       match multiple files.
261
262       The following file types are defined for foghorn:
263
264
265
266       foghorn_exec_t
267
268       - Set files with the foghorn_exec_t type, if you want to transition  an
269       executable to the foghorn_t domain.
270
271
272
273       foghorn_initrc_exec_t
274
275       - Set files with the foghorn_initrc_exec_t type, if you want to transi‐
276       tion an executable to the foghorn_initrc_t domain.
277
278
279
280       foghorn_tmpfs_t
281
282       - Set files with the foghorn_tmpfs_t type, if you want to store foghorn
283       files on a tmpfs file system.
284
285
286
287       foghorn_var_log_t
288
289       -  Set  files with the foghorn_var_log_t type, if you want to treat the
290       data as foghorn var log data, usually stored under the /var/log  direc‐
291       tory.
292
293
294
295       foghorn_var_run_t
296
297       -  Set  files with the foghorn_var_run_t type, if you want to store the
298       foghorn files under the /run or /var/run 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.
