sysadm_dbusd_selinux(8)

hey bestie 💖 welcome to sysadm_dbusd_selinux(8) — the SELinux Policy sysadm_dbusd page, aka the group chat for the sysadm_dbusd processes. it’s giving security manual, but make it make sense ✨

🎀 NAME 🎀

sysadm_dbusd_selinux — Security Enhanced Linux Policy for the sysadm_dbusd processes 🫶

✨ DESCRIPTION ✨

SELinux secures the sysadm_dbusd processes with flexible mandatory access control. no cap, that’s the whole security vibe 💅

The sysadm_dbusd processes execute with the sysadm_dbusd_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 sysadm_dbusd_t

🚪 ENTRYPOINTS 🚪

The sysadm_dbusd_t SELinux type can be entered via the dbusd_exec_t file type.

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

• /usr/bin/dbus-daemon(-1)?
• /usr/bin/dbus-broker
• /usr/bin/dbus-broker-launch
• /lib/dbus-1/dbus-daemon-launch-helper
• /usr/lib/dbus-1/dbus-daemon-launch-helper
• /usr/libexec/dbus-1/dbus-daemon-launch-helper

🧬 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 sysadm_dbusd policy is very flexible allowing users to setup their sysadm_dbusd processes in as secure a method as possible.

The following process types are defined for sysadm_dbusd:

• sysadm_dbusd_t

Note: semanage permissive -a sysadm_dbusd_t can be used to make the process type sysadm_dbusd_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. sysadm_dbusd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sysadm_dbusd with the tightest access possible.

• fips_mode — if you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. Run setsebool -P fips_mode 1.
• nis_enabled — if you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. Run setsebool -P nis_enabled 1.

📁 MANAGED FILES 📁

The SELinux process type sysadm_dbusd_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.

• cifs_t
• ecryptfs_t — default paths:
  • /home/[^/]+/.Private(/.*)?
  • /home/[^/]+/.ecryptfs(/.*)?
• fusefs_t — default path:
  • /run/user/[0-9]+/gvfs
• krb5_host_rcache_t — default paths:
  • /var/tmp/krb5_0.rcache2
  • /var/cache/krb5rcache(/.*)?
  • /var/tmp/nfs_0
  • /var/tmp/DNS_25
  • /var/tmp/host_0
  • /var/tmp/imap_0
  • /var/tmp/HTTP_23
  • /var/tmp/HTTP_48
  • /var/tmp/ldap_55
  • /var/tmp/ldap_487
  • /var/tmp/ldapmap1_0
• nfs_t
• security_t — default path:
  • /selinux
• session_dbusd_tmp_t — default paths:
  • /run/user/[0-9]+/bus
  • /run/user/[0-9]+/dbus(/.*)?
  • /run/user/[0-9]+/dbus-1(/.*)?
• user_home_t — default path:
  • /home/[^/]+/.+

🛠️ 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.
