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.
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:
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
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.
