virsh_ssh_selinux(8)

💖 NAME 💖

virsh_ssh_selinux(8) — the Security Enhanced Linux Policy for the virsh_ssh processes. That’s the whole vibe: SELinux policy, virsh_ssh, and keeping those processes in check. 💅

✨ DESCRIPTION ✨

Okay so Security-Enhanced Linux secures the virsh_ssh processes via flexible mandatory access control. It’s giving mandatory, bestie — not optional aesthetic. 😌

The virsh_ssh processes execute with the virsh_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 virsh_ssh_t

🚪 ENTRYPOINTS 🚪

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

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

/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. SELinux virsh_ssh policy is very flexible, allowing users to setup their virsh_ssh processes in as secure a method as possible. 🛡️

The following process types are defined for virsh_ssh:

• virsh_ssh_t

🫶 Note: semanage permissive -a virsh_ssh_t can be used to make the process type virsh_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. virsh_ssh policy is extremely flexible and has several booleans that allow you to manipulate the policy and run virsh_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 virsh_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. 🔐

xenfs_t

This file type is listed too, but the manpage gives no default paths for it. 🦋

🛠️ 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.
