πŸ’– NAME πŸ’–

okay bestie, welcome to bacula_selinux(8) β€” the manual page for SELinux Policy bacula. It's giving security-enhanced Linux policy for the bacula processes, and we are keeping every single detail. periodt. πŸ’…

✨ DESCRIPTION ✨

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

The bacula processes execute with the bacula_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 bacula_t

πŸšͺ ENTRYPOINTS πŸšͺ

The bacula_t SELinux type can be entered via the bacula_exec_t file type.

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

/usr/bin/bacula.*

πŸ‘‘ PROCESS TYPES πŸ‘‘

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 bacula policy is very flexible, allowing users to setup their bacula processes in as secure a method as possible.

The following process types are defined for bacula:

bacula_t, bacula_admin_t, bacula_unconfined_script_t

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

πŸŽ€ BOOLEANS πŸŽ€

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

  • 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

πŸ”Œ PORT TYPES πŸ”Œ

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 bacula policy is very flexible, allowing users to setup their bacula processes in as secure a method as possible.

The following port types are defined for bacula:

bacula_port_t

Default Defined Ports:

tcp 9103
udp 9103

πŸ“ MANAGED FILES πŸ“

The SELinux process type bacula_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.

πŸ—‚οΈ FILE CONTEXTS πŸ—‚οΈ

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 bacula policy is very flexible, allowing users to setup their bacula processes in as secure a method as possible.

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for bacula. 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 bacula_exec_t '/srv/bacula/content(/.*)?'
restorecon -R -v /srv/mybacula_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for bacula:

  • bacula_admin_exec_t β€” Set files with the bacula_admin_exec_t type, if you want to transition an executable to the bacula_admin_t domain.
    • Paths: /usr/bin/bat, /usr/bin/bconsole
  • bacula_etc_t β€” Set files with the bacula_etc_t type, if you want to store bacula files in the /etc directories.
  • bacula_exec_t β€” Set files with the bacula_exec_t type, if you want to transition an executable to the bacula_t domain.
  • bacula_initrc_exec_t β€” Set files with the bacula_initrc_exec_t type, if you want to transition an executable to the bacula_initrc_t domain.
  • bacula_log_t β€” Set files with the bacula_log_t type, if you want to treat the data as bacula log data, usually stored under the /var/log directory.
  • bacula_spool_t β€” Set files with the bacula_spool_t type, if you want to store the bacula files under the /var/spool directory.
  • bacula_store_t β€” Set files with the bacula_store_t type, if you want to treat the files as bacula store data.
    • Paths: /bacula(/.*)?, /var/bacula(/.*)?
  • bacula_tmp_t β€” Set files with the bacula_tmp_t type, if you want to store bacula temporary files in the /tmp directories.
  • bacula_unconfined_script_exec_t β€” Set files with the bacula_unconfined_script_exec_t type, if you want to transition an executable to the bacula_unconfined_script_t domain.
  • bacula_var_lib_t β€” Set files with the bacula_var_lib_t type, if you want to store the bacula files under the /var/lib directory.
  • bacula_var_run_t β€” Set files with the bacula_var_run_t type, if you want to store the bacula 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. 🫢

πŸ› οΈ COMMANDS πŸ› οΈ

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.
