NAME

6       phc2sys_selinux  -  Security Enhanced Linux Policy for the phc2sys pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  phc2sys  processes  via  flexible
11       mandatory access control.
12
13       The  phc2sys processes execute with the phc2sys_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 phc2sys_t
20
21
22

ENTRYPOINTS

24       The  phc2sys_t  SELinux type can be entered via the phc2sys_exec_t file
25       type.
26
27       The default entrypoint paths for the phc2sys_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/phc2sys
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       phc2sys  policy  is very flexible allowing users to setup their phc2sys
40       processes in as secure a method as possible.
41
42       The following process types are defined for phc2sys:
43
44       phc2sys_t
45
46       Note: semanage permissive -a phc2sys_t can be used to make the  process
47       type  phc2sys_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.  phc2sys
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run phc2sys with the tightest access possi‐
56       ble.

MANAGED FILES

133       The SELinux process type phc2sys_t can manage files  labeled  with  the
134       following file types.  The paths listed are the default paths for these
135       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

212       SELinux requires files to have an extended attribute to define the file
213       type.
214
215       You can see the context of a file using the -Z option to ls
216
217       Policy  governs  the  access  confined  processes  have to these files.
218       SELinux phc2sys policy is very flexible allowing users to  setup  their
219       phc2sys processes in as secure a method as possible.
220
221       The following file types are defined for phc2sys:
222
223
224
225       phc2sys_exec_t
226
227       -  Set files with the phc2sys_exec_t type, if you want to transition an
228       executable to the phc2sys_t domain.
229
230
231
232       phc2sys_initrc_exec_t
233
234       - Set files with the phc2sys_initrc_exec_t type, if you want to transi‐
235       tion an executable to the phc2sys_initrc_t domain.
236
237
238
239       Note:  File context can be temporarily modified with the chcon command.
240       If you want to permanently change the file context you need to use  the
241       semanage fcontext command.  This will modify the SELinux labeling data‐
242       base.  You will need to use restorecon to apply the labels.
243
244

COMMANDS

246       semanage fcontext can also be used to manipulate default  file  context
247       mappings.
248
249       semanage  permissive  can  also  be used to manipulate whether or not a
250       process type is permissive.
251
252       semanage module can also be used to enable/disable/install/remove  pol‐
253       icy modules.
254
255       semanage boolean can also be used to manipulate the booleans
256
257
258       system-config-selinux is a GUI tool available to customize SELinux pol‐
259       icy settings.
