sge_job_ssh_selinux(8)

📦 version 38.1.87, in centos-stream 9

okay so bestie, this is the manual page for sge_job_ssh_selinux(8), and it's literally the SELinux Policy for the sge_job_ssh processes. like, the whole vibe is keeping your processes safe and slay. 💅✨

✨ NAME ✨

sge_job_ssh_selinux — Security Enhanced Linux Policy for the sge_job_ssh processes 🎀

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the sge_job_ssh processes via flexible mandatory access control. no cap, it's giving security but make it customizable.

The sge_job_ssh processes execute with the sge_job_ssh_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. periodt.

for example:

ps -eZ | grep sge_job_ssh_t

🚪 ENTRYPOINTS 🚪

the sge_job_ssh_t SELinux type can be entered via the ssh_exec_t file type. iykyk.

the default entrypoint paths for the sge_job_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. it's kinda iconic.

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

policy governs the access confined processes have to files. SELinux sge_job_ssh policy is very flexible allowing users to setup their sge_job_ssh processes in as secure a method as possible. obsessed with the flexibility honestly.

the following process types are defined for sge_job_ssh:

  • sge_job_ssh_t
Note: semanage permissive -a sge_job_ssh_t can be used to make the process type sge_job_ssh_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 a free pass, just a softer no. 💀

🎛️ BOOLEANS 🎛️

SELinux policy is customizable based on least access required. sge_job_ssh policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sge_job_ssh with the tightest access possible. main character energy for real.

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

if you want to allow sge to access nfs file systems, you must turn on the sge_use_nfs boolean. Disabled by default.

setsebool -P sge_use_nfs 1

📁 MANAGED FILES 📁

the SELinux process type sge_job_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. so like, don't forget the basics bestie. 🫶

krb5_host_rcache_t

  • /var/tmp/krb5_0.rcache2
  • /var/cache/krb5rcache(/.*)?

🛠️ COMMANDS 🛠️

  • semanage fcontext can also be used to manipulate default file context mappings. lowkey useful.
  • semanage permissive can also be used to manipulate whether or not a process type is permissive. iconic.
  • semanage module can also be used to enable/disable/install/remove policy modules. slay.
  • semanage boolean can also be used to manipulate the booleans. yes bestie.
  • system-config-selinux is a GUI tool available to customize SELinux policy settings. for the visual girlies.
