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

109
110
111 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113
114 setsebool -P fips_mode 1
115
116
117
118 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120
121 setsebool -P global_ssp 1
122
123
124
125 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127
128 setsebool -P init_upstart 1
129
130
131
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.

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
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.
