Security Enhanced Linux Policy for the httpd_php processes


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

The httpd_php processes execute with the httpd_php_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep httpd_php_t


The httpd_php_t SELinux type can be entered via the httpd_php_exec_t file type.

The default entrypoint paths for the httpd_php_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 psbP

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

The following process types are defined for httpd_php:


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


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

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to allow HTTPD scripts and modules to connect to databases over the network, you must turn on the httpd_can_network_connect_db boolean. Disabled by default.

setsebool -P httpd_can_network_connect_db 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

Managed Files

The SELinux process type httpd_php_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.





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.
