6 httpd_php_selinux - Security Enhanced Linux Policy for the httpd_php
7 processes
8
10 Security-Enhanced Linux secures the httpd_php processes via flexible
11 mandatory access control.
12
13 The httpd_php processes execute with the httpd_php_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 httpd_php_t
20
21
22
24 The httpd_php_t SELinux type can be entered via the httpd_php_exec_t
25 file type.
26
27 The default entrypoint paths for the httpd_php_t domain are the follow‐
28 ing:
29
30
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 httpd_php policy is very flexible allowing users to setup their
40 httpd_php processes in as secure a method as possible.
41
42 The following process types are defined for httpd_php:
43
44 httpd_php_t
45
46 Note: semanage permissive -a httpd_php_t can be used to make the
47 process type httpd_php_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 httpd_php policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run httpd_php with the tightest
56 access possible.

112
113

122 over the network, you must turn on the httpd_can_network_connect_db
123 boolean. Disabled by default.
124
125 setsebool -P httpd_can_network_connect_db 1
126

128
129 If you want to allow confined applications to run with kerberos, you
130 must turn on the kerberos_enabled boolean. Enabled by default.
131
132 setsebool -P kerberos_enabled 1
133
134
135
136 If you want to allow system to run with NIS, you must turn on the
137 nis_enabled boolean. Disabled by default.
138
139 setsebool -P nis_enabled 1
140
141
142
143 If you want to allow confined applications to use nscd shared memory,
144 you must turn on the nscd_use_shm boolean. Disabled by default.

159 The SELinux process type httpd_php_t can manage files labeled with the
160 following file types. The paths listed are the default paths for these
161 file types. Note the processes UID still need to have DAC permissions.
162
163 httpd_php_tmp_t
164
165
166
168 semanage fcontext can also be used to manipulate default file context
169 mappings.
170
171 semanage permissive can also be used to manipulate whether or not a
172 process type is permissive.
173
174 semanage module can also be used to enable/disable/install/remove pol‐
175 icy modules.
176
177 semanage boolean can also be used to manipulate the booleans
178
179
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
181 icy settings.
