Security Enhanced Linux Policy for the ricci_modclusterd processes

Description

Security-Enhanced Linux secures the ricci_modclusterd processes via flexible mandatory access control.

The ricci_modclusterd processes execute with the ricci_modclusterd_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 ricci_modclusterd_t

Entrypoints

The ricci_modclusterd_t SELinux type can be entered via the ricci_modclusterd_exec_t file type.

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

/usr/sbin/modclusterd

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 psbP

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

The following process types are defined for ricci_modclusterd:

ricci_modcluster_t, ricci_modclusterd_t

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

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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

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

The following port types are defined for ricci_modclusterd:

    ricci_modcluster_port_t

Default Defined Ports: tcp 16851 udp 16851

Managed Files

The SELinux process type ricci_modclusterd_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 lsbP

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the ricci_modclusterd, 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 ricci_modclusterd_exec_t '/srv/ricci_modclusterd/content(/.*)?'
restorecon -R -v /srv/myricci_modclusterd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for ricci_modclusterd:

ricci_modclusterd_exec_t

- Set files with the ricci_modclusterd_exec_t type, if you want to transition an executable to the ricci_modclusterd_t domain.

ricci_modclusterd_tmpfs_t

- Set files with the ricci_modclusterd_tmpfs_t type, if you want to store ricci modclusterd files on a tmpfs file system.

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.
