Security-Enhanced Linux secures the httpd_sys_script processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the httpd_sys_script_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the httpd_sys_script_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
semanage fcontext -a -t public_content_t "/var/httpd_sys_script(/.*)?"
restorecon -F -R -v /var/httpd_sys_script
semanage fcontext -a -t public_content_rw_t "/var/httpd_sys_script/incoming(/.*)?"
restorecon -F -R -v /var/httpd_sys_script/incoming
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
You can see the context of a file using the -Z option to lsP 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.
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.
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.
You can see the context of a process using the -Z option to psP 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 PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
