pki_ra_selinux − Security Enhanced Linux Policy for the pki_ra processes
Security-Enhanced Linux secures the pki_ra processes via flexible mandatory access control.
The pki_ra processes execute with the pki_ra_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 pki_ra_t
The pki_ra_t SELinux type can be entered via the pki_ra_exec_t, httpd_exec_t file types.
The default entrypoint paths for the pki_ra_t domain are the following:
/var/lib/pki-ra/pki-ra, /usr/sbin/httpd(.worker)?, /usr/sbin/apache(2)?, /usr/lib/apache-ssl/.+, /usr/sbin/apache-ssl(2)?, /usr/share/jetty/bin/jetty.sh, /usr/sbin/nginx, /usr/sbin/thttpd, /usr/sbin/php-fpm, /usr/sbin/cherokee, /usr/sbin/lighttpd, /usr/sbin/httpd.event, /usr/bin/mongrel_rails, /usr/sbin/htcacheclean
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 pki_ra policy is very flexible allowing users to setup their pki_ra processes in as secure a method as possible.
The following process types are defined for pki_ra:
pki_ra_t
Note: semanage permissive -a pki_ra_t can be used to make the process type pki_ra_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. pki_ra policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pki_ra with the tightest access possible.

SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux pki_ra policy is very flexible allowing users to setup their pki_ra processes in as secure a method as possible.
The following
port types are defined for pki_ra:
pki_ra_port_t
Default Defined Ports:
tcp 12888-12889
The SELinux process type pki_ra_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.

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 pki_ra policy is very flexible allowing users to setup their pki_ra processes in as secure a method as possible.
EQUIVALENCE DIRECTORIES
pki_ra policy stores data with multiple different file context types under the /var/lib/pki-ra directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv dirctory you would execute the following command:
semanage
fcontext -a -e /var/lib/pki-ra /srv/pki-ra
restorecon -R -v /srv/pki-ra
STANDARD FILE CONTEXT
SELinux defines the file context types for the pki_ra, 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 pki_ra_etc_rw_t
’/srv/pki_ra/content(/.*)?’
restorecon -R -v /srv/mypki_ra_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for pki_ra:
pki_ra_etc_rw_t
- Set files
with the pki_ra_etc_rw_t type, if you want to treat the
files as pki ra etc read/write content.
Paths:
/etc/pki-ra(/.*)?, /etc/sysconfig/pki/ra(/.*)?
pki_ra_exec_t
- Set files with the pki_ra_exec_t type, if you want to transition an executable to the pki_ra_t domain.
pki_ra_lock_t
- Set files with the pki_ra_lock_t type, if you want to treat the files as pki ra lock data, stored under the /var/lock directory
pki_ra_log_t
- Set files with the pki_ra_log_t type, if you want to treat the data as pki ra log data, usually stored under the /var/log directory.
pki_ra_script_exec_t
- Set files with the pki_ra_script_exec_t type, if you want to transition an executable to the pki_ra_script_t domain.
pki_ra_tmp_t
- Set files with the pki_ra_tmp_t type, if you want to store pki ra temporary files in the /tmp directories.
pki_ra_tomcat_exec_t
- Set files with the pki_ra_tomcat_exec_t type, if you want to transition an executable to the pki_ra_tomcat_t domain.
pki_ra_var_lib_t
- Set files with the pki_ra_var_lib_t type, if you want to store the pki ra files under the /var/lib directory.
pki_ra_var_run_t
- Set files with the pki_ra_var_run_t type, if you want to store the pki ra files under the /run or /var/run directory.
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.
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 port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
