6 httpd_user_script_selinux - Security Enhanced Linux Policy for the
7 httpd_user_script processes
8
10 Security-Enhanced Linux secures the httpd_user_script processes via
11 flexible mandatory access control.
12
13 The httpd_user_script processes execute with the httpd_user_script_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep httpd_user_script_t
20
21
22
24 The httpd_user_script_t SELinux type can be entered via the
25 httpd_user_script_exec_t, httpd_user_script_exec_t, httpdcontent file
26 types.
27
28 The default entrypoint paths for the httpd_user_script_t domain are the
29 following:
30
31 /home/[^/]+/((www)|(web)|(public_html))/cgi-bin(/.+)?,
32 /home/[^/]+/((www)|(web)|(public_html))/cgi-bin(/.+)?
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 httpd_user_script policy is very flexible allowing users to setup their
42 httpd_user_script processes in as secure a method as possible.
43
44 The following process types are defined for httpd_user_script:
45
46 httpd_user_script_t
47
48 Note: semanage permissive -a httpd_user_script_t can be used to make
49 the process type httpd_user_script_t permissive. SELinux does not deny
50 access to permissive process types, but the AVC (SELinux denials) mes‐
51 sages are still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 httpd_user_script policy is extremely flexible and has several booleans
57 that allow you to manipulate the policy and run httpd_user_script with
58 the tightest access possible.
59
60
61
62 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65
66 setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to allow httpd cgi support, you must turn on the
78 httpd_enable_cgi boolean. Enabled by default.
79
80 setsebool -P httpd_enable_cgi 1
81
82
83
84 If you want to allow httpd to read home directories, you must turn on
85 the httpd_enable_homedirs boolean. Disabled by default.
86
87 setsebool -P httpd_enable_homedirs 1
88
89
90
91 If you want to allow httpd to read user content, you must turn on the
92 httpd_read_user_content boolean. Disabled by default.
93
94 setsebool -P httpd_read_user_content 1
95
96
97
98 If you want to allow confined applications to run with kerberos, you
99 must turn on the kerberos_enabled boolean. Enabled by default.
100
101 setsebool -P kerberos_enabled 1
102
103
104
105 If you want to allow system to run with NIS, you must turn on the
106 nis_enabled boolean. Disabled by default.
107
108 setsebool -P nis_enabled 1
109
110
111
112 If you want to allow confined applications to use nscd shared memory,
113 you must turn on the nscd_use_shm boolean. Disabled by default.
114
115 setsebool -P nscd_use_shm 1
116
117
118
120 The SELinux process type httpd_user_script_t can manage files labeled
121 with the following file types. The paths listed are the default paths
122 for these file types. Note the processes UID still need to have DAC
123 permissions.
124
125 httpd_user_content_t
126
127 /home/[^/]+/((www)|(web)|(public_html))(/.+)?
128
129 httpd_user_ra_content_t
130
131 /home/[^/]+/((www)|(web)|(public_html))(/.*)?/logs(/.*)?
132
133 httpd_user_rw_content_t
134
135
136
138 SELinux requires files to have an extended attribute to define the file
139 type.
140
141 You can see the context of a file using the -Z option to ls
142
143 Policy governs the access confined processes have to these files.
144 SELinux httpd_user_script policy is very flexible allowing users to
145 setup their httpd_user_script processes in as secure a method as possi‐
146 ble.
147
148 The following file types are defined for httpd_user_script:
149
150
151
152 httpd_user_script_exec_t
153
154 - Set files with the httpd_user_script_exec_t type, if you want to
155 transition an executable to the httpd_user_script_t domain.
156
157
158
159 Note: File context can be temporarily modified with the chcon command.
160 If you want to permanently change the file context you need to use the
161 semanage fcontext command. This will modify the SELinux labeling data‐
162 base. You will need to use restorecon to apply the labels.
163
164
166 semanage fcontext can also be used to manipulate default file context
167 mappings.
168
169 semanage permissive can also be used to manipulate whether or not a
170 process type is permissive.
171
172 semanage module can also be used to enable/disable/install/remove pol‐
173 icy modules.
174
175 semanage boolean can also be used to manipulate the booleans
176
177
178 system-config-selinux is a GUI tool available to customize SELinux pol‐
179 icy settings.
