pki_ra_selinux(8)

✨ NAME ✨

Okay bestie, so this is pki_ra_selinux — the Security Enhanced Linux Policy for the pki_ra processes. Slay. 💅

---

🎀 DESCRIPTION 🎀

Security-Enhanced Linux secures the pki_ra processes via flexible mandatory access control. It's giving "your processes are safe, periodt."

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 — lowkey iconic.

For example:

ps -eZ | grep pki_ra_t

---

🦋 ENTRYPOINTS 🦋

The pki_ra_t SELinux type can be entered via the pki_ra_exec_t file type. Main character energy fr fr.

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

/var/lib/pki-ra/pki-ra

---

🌸 PROCESS TYPES 🌸

SELinux defines process types (domains) for each process running on the system. No cap.

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. Obsessed with the flexibility honestly.

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. So like, it's chill but the receipts still exist. 😭

---

💖 BOOLEANS 💖

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. It's giving "control freak but make it secure."

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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

setsebool -P nis_enabled 1

---

🫶 PORT TYPES 🫶

SELinux defines port types to represent TCP and UDP ports. The way that ports need types too. 💅

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

---

😭 MANAGED FILES 😭

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 — can't skip that step, bestie.

🔥 FILE CONTEXTS 🔥

SELinux requires files to have an extended attribute to define the file type. It's giving "labels are everything."

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 directory, 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 different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t pki_ra_tomcat_exec_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 — regex girlies rise. 💅

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. Temporary vs permanent, know the difference bestie. 🎀

👑 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 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. For the girlies who prefer clicking. 💅
