πŸ’… amanda_selinux(8) β€” the ✨ girl's guide ✨

okay so real talk bestie, this is the amanda_selinux(8) page and it's all about how SELinux keeps the amanda processes on a leash. let's get into it πŸŽ€


🌸 NAME 🌸

amanda_selinux β€” the Security Enhanced Linux Policy for the amanda processes. that's it, that's the vibe ✨


πŸ¦‹ DESCRIPTION πŸ¦‹

Security-Enhanced Linux secures the amanda processes via flexible mandatory access control. yes ma'am, mandatory β€” SELinux does not ask, it tells πŸ’…

The amanda processes execute with the amanda_t SELinux type. wanna check if you've got these processes running? execute the ps command with the -Z qualifier, like:

ps -eZ | grep amanda_t

go off, -Z πŸ‘‘


πŸšͺ ENTRYPOINTS πŸšͺ

The amanda_t SELinux type can be entered via the amanda_inetd_exec_t file type. that's the door, that's the entrance, that's the main character moment πŸšͺ✨

The default entrypoint paths for the amanda_t domain are literally these:

/usr/bin/amandad, /usr/lib/amanda/amandad, /usr/lib/amanda/amindexd,
/usr/lib/amanda/amidxtaped

🧬 PROCESS TYPES 🧬

SELinux defines process types (domains) for each process running on the system. every process gets a little identity, iconic behavior fr fr πŸ’–

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux amanda policy is very flexible allowing users to setup their amanda processes in as secure a method as possible. highkey obsessed with how flexible this is 🫢

The following process types are defined for amanda:

amanda_t, amanda_recover_t

Note: semanage permissive -a amanda_t can be used to make the process type amanda_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like... it's not punishing you but it's still taking notes πŸ“πŸ’€

πŸ”˜ BOOLEANS πŸ”˜

SELinux policy is customizable based on least access required. amanda policy is extremely flexible and has several booleans that allow you to manipulate the policy and run amanda with the tightest access possible. tiny toggles, big energy 🌈

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. gotta label the doors too πŸšͺπŸ”’

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

The following port types are defined for amanda:

amanda_port_t

Default Defined Ports:

tcp 10080-10083
udp 10080-10082

πŸ“ MANAGED FILES πŸ“

The SELinux process type amanda_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 β€” SELinux said "i did my part, now you show me your UID" πŸ˜­πŸ’…

πŸ—‚οΈ FILE CONTEXTS πŸ—‚οΈ

SELinux requires files to have an extended attribute to define the file type. every file's gotta carry its little label, no exceptions 🏷️✨

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

πŸ” EQUIVALENCE DIRECTORIES πŸ”

amanda policy stores data with multiple different file context types under the /var/lib/amanda 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/amanda /srv/amanda
restorecon -R -v /srv/amanda

look at that, relocation but make it compliant πŸ’–

πŸ“Œ STANDARD FILE CONTEXT πŸ“Œ

SELinux defines the file context types for the amanda, 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 amanda_exec_t '/srv/amanda/content(/.*)?'
restorecon -R -v /srv/myamanda_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🌸

The following file types are defined for amanda:

amanda_amandates_t

  • Set files with the amanda_amandates_t type, if you want to treat the files as amanda amandates data.

amanda_config_t

  • Set files with the amanda_config_t type, if you want to treat the files as amanda configuration data, usually stored under the /etc directory.

Paths:

/etc/amanda(/.*)?, /var/lib/amanda/.amandahosts

amanda_data_t

  • Set files with the amanda_data_t type, if you want to treat the files as amanda content.

Paths:

/etc/amanda/.*/index(/.*)?, /etc/amanda/.*/tapelist(/.*)?,
/var/lib/amanda/[^/]+(/.*)?, /etc/amanda/DailySet1(/.*)?

amanda_dumpdates_t

  • Set files with the amanda_dumpdates_t type, if you want to treat the files as amanda dumpdates data.

amanda_exec_t

  • Set files with the amanda_exec_t type, if you want to transition an executable to the amanda_t domain.

amanda_gnutarlists_t

  • Set files with the amanda_gnutarlists_t type, if you want to treat the files as amanda gnutarlists data.

amanda_inetd_exec_t

  • Set files with the amanda_inetd_exec_t type, if you want to transition an executable to the amanda_inetd_t domain.

Paths:

/usr/bin/amandad, /usr/lib/amanda/amandad,
/usr/lib/amanda/amindexd, /usr/lib/amanda/amidxtaped

amanda_log_t

  • Set files with the amanda_log_t type, if you want to treat the data as amanda log data, usually stored under the /var/log directory.

Paths:

/var/log/amanda(/.*)?, /var/lib/amanda/[^/]*/log(/.*)?

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.

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.

amanda_tmp_t

  • Set files with the amanda_tmp_t type, if you want to store amanda temporary files in the /tmp directories.

amanda_tmpfs_t

  • Set files with the amanda_tmpfs_t type, if you want to store amanda files on a tmpfs file system.

amanda_unit_file_t

  • Set files with the amanda_unit_file_t type, if you want to treat the files as amanda unit content.

amanda_usr_lib_t

  • Set files with the amanda_usr_lib_t type, if you want to treat the files as amanda usr lib data.

amanda_var_lib_t

  • Set files with the amanda_var_lib_t type, if you want to store the amanda files under the /var/lib directory.

/var/lib/amanda(/.*)?, /var/lib/amanda/[^/]+/index(/.*)?,
/var/lib/xfsdump/inventory(/.*)?, /var/lib/amanda
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 = chcon era, permanent = semanage fcontext era, no in-between bestie πŸ’€βœ¨

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. a whole GUI, for the girlies who like a lil clicky-click πŸ–±οΈπŸ’…
