6 httpd_sys_script_selinux - Security Enhanced Linux Policy for the
7 httpd_sys_script processes
8
10 Security-Enhanced Linux secures the httpd_sys_script processes via
11 flexible mandatory access control.
12
13 The httpd_sys_script processes execute with the httpd_sys_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_sys_script_t
20
21
22
24 The httpd_sys_script_t SELinux type can be entered via the
25 httpd_sys_content_t, cifs_t, httpd_sys_script_exec_t, nfs_t, httpdcon‐
26 tent file types.
27
28 The default entrypoint paths for the httpd_sys_script_t domain are the
29 following:
30
31 /srv/([^/]*/)?www(/.*)?, /var/www(/.*)?, /etc/htdig(/.*)?,
32 /srv/gallery2(/.*)?, /var/lib/trac(/.*)?, /var/lib/htdig(/.*)?,

46 SELinux defines process types (domains) for each process running on the
47 system
48
49 You can see the context of a process using the -Z option to ps
50
51 Policy governs the access confined processes have to files. SELinux
52 httpd_sys_script policy is very flexible allowing users to setup their
53 httpd_sys_script processes in as secure a method as possible.
54
55 The following process types are defined for httpd_sys_script:
56
57 httpd_sys_script_t
58
59 Note: semanage permissive -a httpd_sys_script_t can be used to make the
60 process type httpd_sys_script_t permissive. SELinux does not deny ac‐
61 cess to permissive process types, but the AVC (SELinux denials) mes‐
62 sages are still generated.
63
64
66 SELinux policy is customizable based on least access required.
67 httpd_sys_script policy is extremely flexible and has several booleans
68 that allow you to manipulate the policy and run httpd_sys_script with
69 the tightest access possible.

256 SELinux requires files to have an extended attribute to define the file
257 type.
258
259 You can see the context of a file using the -Z option to ls
260
261 Policy governs the access confined processes have to these files.
262 SELinux httpd_sys_script policy is very flexible allowing users to
263 setup their httpd_sys_script processes in as secure a method as possi‐
264 ble.
265
266 The following file types are defined for httpd_sys_script:
267
268
269
270 httpd_sys_script_exec_t
271
272 - Set files with the httpd_sys_script_exec_t type, if you want to tran‐
273 sition an executable to the httpd_sys_script_t domain.
274
275
276 Paths:
277 /opt/.*.cgi, /usr/.*.cgi, /var/www/[^/]*/cgi-bin(/.*)?,
278 /var/www/perl(/.*)?, /var/www/html/[^/]*/cgi-bin(/.*)?,
279 /usr/lib/cgi-bin(/.*)?, /var/www/cgi-bin(/.*)?,
280 /var/www/svn/hooks(/.*)?, /usr/share/wordpress/.*.php, /usr/lo‐
281 cal/nagios/sbin(/.*)?, /usr/share/wordpress/wp-includes/.*.php,
282 /usr/share/wordpress-mu/wp-config.php
283
284
285 Note: File context can be temporarily modified with the chcon command.
286 If you want to permanently change the file context you need to use the
287 semanage fcontext command. This will modify the SELinux labeling data‐
288 base. You will need to use restorecon to apply the labels.
289
290
292 If you want to share files with multiple domains (Apache, FTP, rsync,
293 Samba), you can set a file context of public_content_t and public_con‐
294 tent_rw_t. These context allow any of the above domains to read the
295 content. If you want a particular domain to write to the public_con‐
296 tent_rw_t domain, you must set the appropriate boolean.
297
298 Allow httpd_sys_script servers to read the /var/httpd_sys_script direc‐
299 tory by adding the public_content_t file type to the directory and by
300 restoring the file type.
301
302 semanage fcontext -a -t public_content_t "/var/httpd_sys_script(/.*)?"
303 restorecon -F -R -v /var/httpd_sys_script
304
305 Allow httpd_sys_script servers to read and write
306 /var/httpd_sys_script/incoming by adding the public_content_rw_t type
307 to the directory and by restoring the file type. You also need to turn
308 on the httpd_sys_script_anon_write boolean.
309
310 semanage fcontext -a -t public_content_rw_t "/var/httpd_sys_script/in‐
311 coming(/.*)?"
312 restorecon -F -R -v /var/httpd_sys_script/incoming
313 setsebool -P httpd_sys_script_anon_write 1
314
315
316 If you want to allow apache scripts to write to public content, direc‐
317 tories/files must be labeled public_rw_content_t., you must turn on the
318 httpd_sys_script_anon_write boolean.
319
320 setsebool -P httpd_sys_script_anon_write 1
321
322
324 semanage fcontext can also be used to manipulate default file context
325 mappings.
326
327 semanage permissive can also be used to manipulate whether or not a
328 process type is permissive.
329
330 semanage module can also be used to enable/disable/install/remove pol‐
331 icy modules.
332
333 semanage boolean can also be used to manipulate the booleans
334
335
336 system-config-selinux is a GUI tool available to customize SELinux pol‐
337 icy settings.
