💖 apcupsd_..._selinux(8) 💖

okay bestie, so this is the apcupsd_..._selinux(8) page — the SELinux Policy one for apcupsd_cgi_script ✨

---

🌸 NAME 🌸

apcupsd_cgi_script_selinux — literally the Security Enhanced Linux Policy for the apcupsd_cgi_script processes 🫶

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the apcupsd_cgi_script processes via flexible mandatory access control. no cap, that's the whole vibe 💅

So the apcupsd_cgi_script processes execute with the apcupsd_cgi_script_t SELinux type. Wanna check if you've got these processes running? Just run the ps command with the -Z qualifier, iconic behavior. For example:

ps -eZ | grep apcupsd_cgi_script_t

---

🎀 ENTRYPOINTS 🎀

The apcupsd_cgi_script_t SELinux type can be entered via the apcupsd_cgi_script_exec_t file type. that's the doorway, bestie 🚪✨

The default entrypoint paths for the apcupsd_cgi_script_t domain are these cuties:

/var/www/cgi-bin/apcgui(/.*)?, /var/www/apcupsd/multimon.cgi,
/var/www/apcupsd/upsimage.cgi, /var/www/apcupsd/upsstats.cgi,
/var/www/apcupsd/upsfstats.cgi

---

🔥 PROCESS TYPES 🔥

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

The following process types are defined for apcupsd_cgi_script:

• apcupsd_cgi_script_t

Note: semanage permissive -a apcupsd_cgi_script_t can be used to make the process type apcupsd_cgi_script_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 it's still snitching 📢

---

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. The apcupsd_cgi_script policy is extremely flexible and has several booleans that let you manipulate the policy and run apcupsd_cgi_script with the tightest access possible. tightest access = main character energy 🧚

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

If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

---

💀 MANAGED FILES 💀

The SELinux process type apcupsd_cgi_script_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 needs to have DAC permissions — SELinux isn't out here doing your whole job for you, bestie 😭

• apcupsd_cgi_rw_content_t

---

🍓 FILE CONTEXTS 🍓

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for apcupsd_cgi_script. 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. the way that actually works 🫶

semanage fcontext -a -t apcupsd_cgi_script_exec_t '/srv/apcupsd_cgi_script/content(/.*)?'
restorecon -R -v /srv/myapcupsd_cgi_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 apcupsd_cgi_script:

apcupsd_cgi_script_exec_t

• Set files with the apcupsd_cgi_script_exec_t type if you want to transition an executable to the apcupsd_cgi_script_t domain.

Paths:

/var/www/cgi-bin/apcgui(/.*)?, /var/www/apcupsd/multimon.cgi,
/var/www/apcupsd/upsimage.cgi, /var/www/apcupsd/upsstats.cgi,
/var/www/apcupsd/upsfstats.cgi

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 fixes are giving band-aid, permanent ones are giving commitment 💅

---

💅 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 boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings. yes bestie, a GUI, for when the terminal is doing too much 🖱️✨
