💅 amanda_recover_selinux — the SELinux glow-up for amanda_recover

Okay so this is the amanda_recover_selinux(8) page, bestie. It's giving "SELinux Policy amanda_recover" energy, and honestly? It's iconic. Let's get into it.

✨ NAME ✨

amanda_recover_selinux — Security Enhanced Linux Policy for the amanda_recover processes. No cap, that's literally what it is.

🛡️ DESCRIPTION 🛡️

Security-Enhanced Linux secures the amanda_recover processes via flexible mandatory access control. It's the main character of access control, periodt.

The amanda_recover processes execute with the amanda_recover_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. It's a vibe check for your processes.

For example:

ps -eZ | grep amanda_recover_t

Slay. That's how you peep the context.

🚪 ENTRYPOINTS 🚪

The amanda_recover_t SELinux type can be entered via the amanda_recover_exec_t file type. It's like the VIP entrance, lowkey.

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

/usr/bin/amrecover

That's the spot. Don't forget it.

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. It's a whole taxonomy, honestly.

You can see the context of a process using the -Z option to ps. It's giving "who are you and what do you do" energy.

Policy governs the access confined processes have to files. SELinux amanda_recover policy is very flexible allowing users to setup their amanda_recover processes in as secure a method as possible. It's highkey customizable.

The following process types are defined for amanda_recover:

amanda_recover_t
Note: semanage permissive -a amanda_recover_t can be used to make the process type amanda_recover_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. It's like a warning label, not a block.

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. amanda_recover policy is extremely flexible and has several booleans that allow you to manipulate the policy and run amanda_recover with the tightest access possible. It's the "boss mode" of permissions.

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. It's already on, bestie.

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. It's a whole choice.

setsebool -P nis_enabled 1

📂 MANAGED FILES 📂

The SELinux process type amanda_recover_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still need to have DAC permissions. Like, SELinux isn't doing your whole job for you.

  • amanda_log_t — the log files, duh.
/var/log/amanda(/.*)?
/var/lib/amanda/[^/]*/log(/.*)?
  • amanda_recover_dir_t — the restore directory. It's giving "home base".
/root/restore
  • amanda_tmp_t — temporary files, no paths listed, but it's there.
  • krb5_host_rcache_t — the Kerberos cache files. So many paths, it's a whole aesthetic.
/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. It's like a name tag for your files.

You can see the context of a file using the -Z option to ls. It's giving "show me your label".

Policy governs the access confined processes have to these files. SELinux amanda_recover policy is very flexible allowing users to setup their amanda_recover processes in as secure a method as possible. Same energy as before, but for files.

STANDARD FILE CONTEXT

SELinux defines the file context types for amanda_recover. If you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. It's the whole "move it, label it, love it" process.

semanage fcontext -a -t amanda_recover_exec_t '/srv/amanda_recover/content(/.*)?'
restorecon -R -v /srv/myamanda_recover_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. So it's regex, but make it fashion.

The following file types are defined for amanda_recover:

  • amanda_recover_dir_t — Set files with the amanda_recover_dir_t type, if you want to treat the files as amanda recover dir data. It's the directory type, obviously.
  • amanda_recover_exec_t — Set files with the amanda_recover_exec_t type, if you want to transition an executable to the amanda_recover_t domain. It's the entrypoint, the exec, the moment.
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. So chcon is a temporary vibe, semanage is forever.

⚡ COMMANDS ⚡

semanage fcontext can also be used to manipulate default file context mappings. It's the main character of mapping.

semanage permissive can also be used to manipulate whether or not a process type is permissive. It's the "do I block or not" button.

semanage module can also be used to enable/disable/install/remove policy modules. It's the module manager.

semanage boolean can also be used to manipulate the booleans. It's the toggle queen.

system-config-selinux is a GUI tool available to customize SELinux policy settings. For when you want to point and click instead of type, no shame.
