πŸ’… zoneminder_script_selinux(8) β€” the glow-up

okay so bestie, welcome to the zoneminder_script_selinux manual page (that's the manual name, iykyk) β€” the whole SELinux policy situation for the zoneminder_script processes, explained like we're in the group chat. grab a straw-berry drink πŸ“ and let's go.


✨ NAME ✨

zoneminder_script_selinux β€” the Security Enhanced Linux Policy for the zoneminder_script processes. that's it, that's the name, iconic.


πŸ¦‹ DESCRIPTION πŸ¦‹

Security-Enhanced Linux secures the zoneminder_script processes via flexible mandatory access control. yes, flexible, yes, mandatory, both at once, she contains multitudes πŸ’œ.

The zoneminder_script processes execute with the zoneminder_script_t SELinux type. you wanna check if you've got these processes running? run the ps command with the -Z qualifier, easy:

ps -eZ | grep zoneminder_script_t

like, literally that. no cap.


πŸšͺ ENTRYPOINTS πŸšͺ

The zoneminder_script_t SELinux type can be entered via the zoneminder_script_exec_t file type. that's the doorway, that's the vibe check at the door 🫢.

The default entrypoint paths for the zoneminder_script_t domain are:

/usr/libexec/zoneminder/cgi-bin(/.*)?

periodt. one path, one slay.


πŸ‘‘ PROCESS TYPES πŸ‘‘

SELinux defines process types (domains) for each process running on the system. every process gets a little domain, main character energy for everyone πŸŽ€.

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

Policy governs the access confined processes have to files. SELinux zoneminder_script policy is very flexible, allowing users to set up their zoneminder_script processes in as secure a method as possible.

The following process types are defined for zoneminder_script:

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

🌸 BOOLEANS 🌸

SELinux policy is customizable based on least access required. zoneminder_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run zoneminder_script with the tightest access possible. toggles, bestie, we love a toggle 🧚

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 httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default.

setsebool -P httpd_enable_cgi 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

see how the last one says disabled by default? yeah, you actually have to go turn that one ON. don't @ me, that's just what it says πŸ”₯


πŸ“‚ MANAGED FILES πŸ“‚

The SELinux process type zoneminder_script_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and hey β€” note the processes UID still needs to have DAC permissions, SELinux isn't out here doing everything for you πŸ™ˆ

  • zoneminder_rw_content_t
  • zoneminder_tmpfs_t
  • zoneminder_var_lib_t
    • /var/lib/zoneminder(/.*)?

three file types, one path listed, we keep it accurate πŸ’œ


πŸŽ€ FILE CONTEXTS πŸŽ€

SELinux requires files to have an extended attribute to define the file type. like a little name tag but for files, obsessed.

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 zoneminder_script policy is very flexible, allowing users to set up their zoneminder_script processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the zoneminder_script. 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. two-step, but it eats πŸ’…

semanage fcontext -a -t zoneminder_script_exec_t '/srv/zoneminder_script/content(/.*)?'
restorecon -R -v /srv/myzoneminder_script_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🌈

The following file types are defined for zoneminder_script:

  • zoneminder_script_exec_t
    • Set files with the zoneminder_script_exec_t type, if you want to transition an executable to the zoneminder_script_t domain.
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 the "just for tonight" of file contexts, semanage fcontext + restorecon is the whole committed relationship 😭🫢

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 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 when clicking is the mood πŸ–±οΈβœ¨

sign-off szn: this page is zoneminder_script, dated 26-10-06, and yeah the footer still says zonemind...t_selinux(8) because that's what the man page header/footer looks like when it gets truncated β€” a little cunty truncation moment, we respect it πŸ’€πŸ’–
