💖 mongod_selinux(8) — Security Enhanced Linux Policy for the mongod processes 💖

✨ NAME ✨

mongod_selinux — Security Enhanced Linux Policy for the mongod processes. that's the whole name line, bestie, but make it cute: it's the SELinux policy page for mongod, periodt. 💅

🌸 DESCRIPTION 🌸

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

The mongod processes execute with the mongod_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 mongod_t

🦋 ENTRYPOINTS 🦋

The mongod_t SELinux type can be entered via the mongod_exec_t file type.

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

/usr/bin/mongod, /usr/bin/mongos, /usr/libexec/mongodb-scl-helper, /usr/share/aeolus-conductor/dbomatic/dbomatic

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

The following process types are defined for mongod:

mongod_t

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

  • daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default. Turn it on with setsebool -P daemons_dontaudit_scheduling 1.
  • fips_mode — if you want to allow all domains to execute in fips_mode, you must turn on this boolean. Enabled by default. Turn it on with setsebool -P fips_mode 1.
  • nis_enabled — if you want to allow system to run with NIS, you must turn on this boolean. Disabled by default. Turn it on with setsebool -P nis_enabled 1.

🌈 PORT TYPES 🌈

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

Policy governs the access confined processes have to these ports. SELinux mongod policy is very flexible allowing users to setup their mongod processes in as secure a method as possible.

The following port types are defined for mongod:

mongod_port_t

Default Defined Ports: tcp 27017-27019,28017-28019

🍓 MANAGED FILES 🍓

The SELinux process type mongod_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.

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the mongod, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t mongod_exec_t '/srv/mongod/content(/.*)?'
restorecon -R -v /srv/mymongod_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for mongod:

mongod_exec_t

  • Set files with the mongod_exec_t type, if you want to transition an executable to the mongod_t domain.

Paths:

/usr/bin/mongod, /usr/bin/mongos, /usr/libexec/mongodb-scl-helper, /usr/share/aeolus-conductor/dbomatic/dbomatic

mongod_initrc_exec_t

  • Set files with the mongod_initrc_exec_t type, if you want to transition an executable to the mongod_initrc_t domain.

Paths:

/etc/rc.d/init.d/mongod, /etc/rc.d/init.d/mongos

mongod_log_t

  • Set files with the mongod_log_t type, if you want to treat the data as mongod log data, usually stored under the /var/log directory.

Paths:

/var/log/mongo.*, /var/log/aeolus-conductor/dbomatic.log.*

mongod_tmp_t

  • Set files with the mongod_tmp_t type, if you want to store mongod temporary files in the /tmp directories.

mongod_unit_file_t

  • Set files with the mongod_unit_file_t type, if you want to treat the files as mongod unit content.

Paths:

/usr/lib/systemd/system/mongod.*, /usr/lib/systemd/system/mongos.*

mongod_var_lib_t

  • Set files with the mongod_var_lib_t type, if you want to store the mongod files under the /var/lib directory.

mongod_var_run_t

  • Set files with the mongod_var_run_t type, if you want to store the mongod files under the /run or /var/run directory.

Paths:

/run/mongo.*, /run/aeolus/dbomatic.pid
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.

💅 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 port can also be used to manipulate the port definitions
  • semanage boolean can also be used to manipulate the booleans
  • system-config-selinux is a GUI tool available to customize SELinux policy settings.
