NAME

6       httpd_sys_script_selinux  -  Security  Enhanced  Linux  Policy  for the
7       httpd_sys_script processes
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The   httpd_sys_script_t   SELinux   type   can   be  entered  via  the
25       httpd_sys_script_exec_t, httpd_sys_content_t, cifs_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       /opt/.*.cgi,         /usr/.*.cgi,         /var/www/[^/]*/cgi-bin(/.*)?,
32       /var/www/perl(/.*)?,  /var/www/html/[^/]*/cgi-bin(/.*)?,  /usr/lib/cgi-

PROCESS TYPES

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

BOOLEANS

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.

MANAGED FILES

218       The  SELinux  process  type httpd_sys_script_t can manage files labeled
219       with the following file types.  The paths listed are the default  paths
220       for  these  file  types.  Note the processes UID still need to have DAC
221       permissions.

FILE CONTEXTS

300       SELinux requires files to have an extended attribute to define the file
301       type.
302
303       You can see the context of a file using the -Z option to ls
304
305       Policy  governs  the  access  confined  processes  have to these files.
306       SELinux httpd_sys_script policy is  very  flexible  allowing  users  to
307       setup  their httpd_sys_script processes in as secure a method as possi‐
308       ble.
309
310       STANDARD FILE CONTEXT
311
312       SELinux defines the file context types for the httpd_sys_script, if you
313       wanted  to  store files with these types in a different paths, you need
314       to execute the semanage command to specify alternate labeling and  then
315       use restorecon to put the labels on disk.
316
317       semanage       fcontext       -a       -t       httpd_sys_script_exec_t
318       '/srv/httpd_sys_script/content(/.*)?'
319       restorecon -R -v /srv/myhttpd_sys_script_content
320
321       Note: SELinux often uses regular expressions  to  specify  labels  that
322       match multiple files.
323
324       The following file types are defined for httpd_sys_script:
325
326
327
328       httpd_sys_script_exec_t
329
330       - Set files with the httpd_sys_script_exec_t type, if you want to tran‐
331       sition an executable to the httpd_sys_script_t domain.
332
333
334       Paths:
335            /opt/.*.cgi,      /usr/.*.cgi,       /var/www/[^/]*/cgi-bin(/.*)?,
336            /var/www/perl(/.*)?,            /var/www/html/[^/]*/cgi-bin(/.*)?,
337            /usr/lib/cgi-bin(/.*)?,                    /var/www/cgi-bin(/.*)?,
338            /var/www/svn/hooks(/.*)?,   /usr/share/wordpress/.*.php,  /usr/lo‐
339            cal/nagios/sbin(/.*)?,    /usr/share/wordpress/wp-includes/.*.php,
340            /usr/share/wordpress-mu/wp-config.php
341
342
343       Note:  File context can be temporarily modified with the chcon command.
344       If you want to permanently change the file context you need to use  the
345       semanage fcontext command.  This will modify the SELinux labeling data‐
346       base.  You will need to use restorecon to apply the labels.
347
348

SHARING FILES

350       If you want to share files with multiple domains (Apache,  FTP,  rsync,
351       Samba),  you can set a file context of public_content_t and public_con‐
352       tent_rw_t.  These context allow any of the above domains  to  read  the
353       content.   If  you want a particular domain to write to the public_con‐
354       tent_rw_t domain, you must set the appropriate boolean.
355
356       Allow httpd_sys_script servers to read the /var/httpd_sys_script direc‐
357       tory  by  adding the public_content_t file type to the directory and by
358       restoring the file type.
359
360       semanage fcontext -a -t public_content_t "/var/httpd_sys_script(/.*)?"
361       restorecon -F -R -v /var/httpd_sys_script
362
363       Allow    httpd_sys_script     servers     to     read     and     write
364       /var/httpd_sys_script/incoming  by  adding the public_content_rw_t type
365       to the directory and by restoring the file type.  You also need to turn
366       on the httpd_sys_script_anon_write boolean.
367
368       semanage  fcontext -a -t public_content_rw_t "/var/httpd_sys_script/in‐
369       coming(/.*)?"
370       restorecon -F -R -v /var/httpd_sys_script/incoming
371       setsebool -P httpd_sys_script_anon_write 1
372
373
374       If you want to allow apache scripts to write to public content,  direc‐
375       tories/files must be labeled public_rw_content_t., you must turn on the
376       httpd_sys_script_anon_write boolean.
377
378       setsebool -P httpd_sys_script_anon_write 1
379
380

COMMANDS

382       semanage fcontext can also be used to manipulate default  file  context
383       mappings.
384
385       semanage  permissive  can  also  be used to manipulate whether or not a
386       process type is permissive.
387
388       semanage module can also be used to enable/disable/install/remove  pol‐
389       icy modules.
390
391       semanage boolean can also be used to manipulate the booleans
392
393
394       system-config-selinux is a GUI tool available to customize SELinux pol‐
395       icy settings.
