✨ NAME ✨

Welcome to the NetworkM..._selinux(8) page, bestie — the SELinux Policy NetworkManager_ssh manual. It’s all about the Security Enhanced Linux Policy for the NetworkManager_ssh processes. 🫶

🛡️ DESCRIPTION 🛡️

Security-Enhanced Linux secures the NetworkManager_ssh processes via flexible mandatory access control. No cap, that’s the whole vibe. 💅

The NetworkManager_ssh processes execute with the NetworkManager_ssh_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 NetworkManager_ssh_t

🚪 ENTRYPOINTS 🚪

The NetworkManager_ssh_t SELinux type can be entered via the ssh_exec_t file type.

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

• /usr/bin/ssh
• /usr/libexec/nm-ssh-service

👑 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. The SELinux NetworkManager_ssh policy is very flexible, allowing users to set up their NetworkManager_ssh processes in as secure a method as possible. Obsessed. ✨

The following process types are defined for NetworkManager_ssh:

• NetworkManager_ssh_t

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

🎚️ BOOLEANS 🎚️

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

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

📂 MANAGED FILES 📂

The SELinux process type NetworkManager_ssh_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.

🛠️ 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.
