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.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type phc2sys_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

125 SELinux requires files to have an extended attribute to define the file
126 type.
127
128 You can see the context of a file using the -Z option to ls
129
130 Policy governs the access confined processes have to these files.
131 SELinux phc2sys policy is very flexible allowing users to setup their
132 phc2sys processes in as secure a method as possible.
133
134 STANDARD FILE CONTEXT
135
136 SELinux defines the file context types for the phc2sys, if you wanted
137 to store files with these types in a diffent paths, you need to execute
138 the semanage command to sepecify alternate labeling and then use
139 restorecon to put the labels on disk.
140
141 semanage fcontext -a -t phc2sys_unit_file_t '/srv/myphc2sys_con‐
142 tent(/.*)?'
143 restorecon -R -v /srv/myphc2sys_content
144
145 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147
148 The following file types are defined for phc2sys:
149
150
151
152 phc2sys_exec_t
153
154 - Set files with the phc2sys_exec_t type, if you want to transition an
155 executable to the phc2sys_t domain.
156
157
158
159 phc2sys_unit_file_t
160
161 - Set files with the phc2sys_unit_file_t type, if you want to treat the
162 files as phc2sys unit content.
163
164
165
166 Note: File context can be temporarily modified with the chcon command.
167 If you want to permanently change the file context you need to use the
168 semanage fcontext command. This will modify the SELinux labeling data‐
169 base. You will need to use restorecon to apply the labels.
170
171
173 semanage fcontext can also be used to manipulate default file context
174 mappings.
175
176 semanage permissive can also be used to manipulate whether or not a
177 process type is permissive.
178
179 semanage module can also be used to enable/disable/install/remove pol‐
180 icy modules.
181
182 semanage boolean can also be used to manipulate the booleans
183
184
185 system-config-selinux is a GUI tool available to customize SELinux pol‐
186 icy settings.
