NAME

       httpd_sys_script_selinux - Security Enhanced Linux Policy for the httpd_sys_script processes

DESCRIPTION

       Security-Enhanced Linux secures the httpd_sys_script processes via flexible mandatory access control.

       The  httpd_sys_script processes execute with the httpd_sys_script_t SELinux type. You can check if you have these processes running by exe-
       cuting the ps command with the -Z qualifier.

       For example:

       ps -eZ | grep httpd_sys_script_t

ENTRYPOINTS

       The httpd_sys_script_t SELinux type can be entered via  the  httpd_sys_content_t,  httpd_sys_script_exec_t,  shell_exec_t,  cifs_t,  nfs_t,
       httpd_sys_content_t, httpd_sys_script_exec_t, httpdcontent file types.

       The default entrypoint paths for the httpd_sys_script_t domain are the following:

PROCESS TYPES

       SELinux defines process types (domains) for each process running on the system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have to files.  SELinux httpd_sys_script policy is very flexible allowing users to setup their
       httpd_sys_script processes in as secure a method as possible.

       The following process types are defined for httpd_sys_script:

       httpd_sys_script_t

       Note: semanage permissive -a httpd_sys_script_t can be used to make the process type httpd_sys_script_t permissive. SELinux does  not  deny
       access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

       SELinux policy is customizable based on least access required.  httpd_sys_script policy is extremely flexible and has several booleans that
       allow you to manipulate the policy and run httpd_sys_script with the tightest access possible.

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

FILE CONTEXTS

       SELinux requires files to have an extended attribute to define the file type.

       You can see the context of a file using the -Z option to ls

       Policy governs the access confined processes have to these files.  SELinux httpd_sys_script policy is very flexible allowing users to setup
       their httpd_sys_script processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the httpd_sys_script, if you wanted to store files with these types in a diffent paths, you need
       to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t httpd_sys_script_exec_t '/srv/httpd_sys_script/content(/.*)?'
       restorecon -R -v /srv/myhttpd_sys_script_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for httpd_sys_script:

       httpd_sys_script_exec_t

       - Set files with the httpd_sys_script_exec_t type, if you want to transition an executable to the httpd_sys_script_t domain.

       Paths:
	    /usr/.*.cgi,  /opt/.*.cgi,	 /var/www/[^/]*/cgi-bin(/.*)?,	 /var/www/perl(/.*)?,	/var/www/html/[^/]*/cgi-bin(/.*)?,   /usr/lib/cgi-
	    bin(/.*)?,	/var/www/cgi-bin(/.*)?,  /var/www/svn/hooks(/.*)?,  /usr/share/wordpress/.*.php,  /usr/share/wordpress/wp-includes/.*.php,
	    /usr/share/wordpress-mu/wp-config.php

       Note: File context can be temporarily modified with the chcon command.  If you want to permanently change the file context you need to  use
       the semanage fcontext command.  This will modify the SELinux labeling database.	You will need to use restorecon to apply the labels.

SHARING FILES

       If  you	want  to  share  files	with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and pub-
       lic_content_rw_t.  These context allow any of the above domains to read the content.  If you want a particular domain to write to the  pub-
       lic_content_rw_t domain, you must set the appropriate boolean.

       Allow httpd_sys_script servers to read the /var/httpd_sys_script directory by adding the public_content_t file type to the directory and by
       restoring the file type.

       semanage fcontext -a -t public_content_t "/var/httpd_sys_script(/.*)?"
       restorecon -F -R -v /var/httpd_sys_script

       Allow httpd_sys_script servers to read and write /var/httpd_sys_script/incoming by adding the public_content_rw_t type to the directory and
       by restoring the file type.  You also need to turn on the httpd_sys_script_anon_write boolean.

       semanage fcontext -a -t public_content_rw_t "/var/httpd_sys_script/incoming(/.*)?"
       restorecon -F -R -v /var/httpd_sys_script/incoming
       setsebool -P httpd_sys_script_anon_write 1

       If  you	want  to allow apache scripts to write to public content, directories/files must be labeled public_rw_content_t., you must turn on
       the httpd_sys_script_anon_write boolean.

       setsebool -P httpd_sys_script_anon_write 1

COMMANDS

       semanage fcontext can also be used to manipulate default file context mappings.

       semanage permissive can also be used to manipulate whether or not a process type is permissive.

       semanage module can also be used to enable/disable/install/remove policy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
