6 httpd_helper_selinux - Security Enhanced Linux Policy for the
7 httpd_helper processes
8
10 Security-Enhanced Linux secures the httpd_helper processes via flexible
11 mandatory access control.
12
13 The httpd_helper processes execute with the httpd_helper_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep httpd_helper_t
20
21
22
24 The httpd_helper_t SELinux type can be entered via the
25 httpd_helper_exec_t file type.
26
27 The default entrypoint paths for the httpd_helper_t domain are the fol‐
28 lowing:
29
30 /usr/bin/htsslpass
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_helper policy is very flexible allowing users to setup their
40 httpd_helper processes in as secure a method as possible.
41
42 The following process types are defined for httpd_helper:
43
44 httpd_helper_t
45
46 Note: semanage permissive -a httpd_helper_t can be used to make the
47 process type httpd_helper_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_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run httpd_helper with the tight‐
56 est access possible.
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
67 If you want to unify HTTPD to communicate with the terminal. Needed for
68 entering the passphrase for certificates at the terminal, you must turn
69 on the httpd_tty_comm boolean. Disabled by default.
70
71 setsebool -P httpd_tty_comm 1
72
73
74
76 SELinux requires files to have an extended attribute to define the file
77 type.
78
79 You can see the context of a file using the -Z option to ls
80
81 Policy governs the access confined processes have to these files.
82 SELinux httpd_helper policy is very flexible allowing users to setup
83 their httpd_helper processes in as secure a method as possible.
84
85 STANDARD FILE CONTEXT
86
87 SELinux defines the file context types for the httpd_helper, if you
88 wanted to store files with these types in a different paths, you need
89 to execute the semanage command to specify alternate labeling and then
90 use restorecon to put the labels on disk.
91
92 semanage fcontext -a -t httpd_helper_exec_t '/srv/httpd_helper/con‐
93 tent(/.*)?'
94 restorecon -R -v /srv/myhttpd_helper_content
95
96 Note: SELinux often uses regular expressions to specify labels that
97 match multiple files.
98
99 The following file types are defined for httpd_helper:
100
101
102
103 httpd_helper_exec_t
104
105 - Set files with the httpd_helper_exec_t type, if you want to transi‐
106 tion an executable to the httpd_helper_t domain.
107
108
109
110 Note: File context can be temporarily modified with the chcon command.
111 If you want to permanently change the file context you need to use the
112 semanage fcontext command. This will modify the SELinux labeling data‐
113 base. You will need to use restorecon to apply the labels.
114
115
117 semanage fcontext can also be used to manipulate default file context
118 mappings.
119
120 semanage permissive can also be used to manipulate whether or not a
121 process type is permissive.
122
123 semanage module can also be used to enable/disable/install/remove pol‐
124 icy modules.
125
126 semanage boolean can also be used to manipulate the booleans
127
128
129 system-config-selinux is a GUI tool available to customize SELinux pol‐
130 icy settings.
