jabberd_selinux(8) - Linux man page

Name

jabberd_selinux - Security Enhanced Linux Policy for the jabberd processes

Description

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

The jabberd processes execute with the jabberd_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 jabberd_t

Entrypoints

The jabberd_t SELinux type can be entered via the "jabberd_exec_t" file type. The default entrypoint paths for the jabberd_t domain are the following:"

/usr/bin/sm, /usr/bin/s2s, /usr/sbin/jabberd

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

The following process types are defined for jabberd:

jabberd_router_t, jabberd_t

Note: semanage permissive -a jabberd_t

can be used to make the process type jabberd_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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

The following file types are defined for jabberd:

jabberd_exec_t

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

jabberd_initrc_exec_t

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

jabberd_log_t

- Set files with the jabberd_log_t type, if you want to treat the data as jabberd log data, usually stored under the /var/log directory.

jabberd_router_exec_t

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

jabberd_var_lib_t

- Set files with the jabberd_var_lib_t type, if you want to store the jabberd files under the /var/lib directory.

jabberd_var_run_t

- Set files with the jabberd_var_run_t type, if you want to store the jabberd files under the /run directory.

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.

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

The following port types are defined for jabberd:

jabber_client_port_t
Default Defined Ports:
tcp 5222,5223
jabber_interserver_port_t
Default Defined Ports:
tcp 5269
jabber_router_port_t
Default Defined Ports:
tcp 5347

Managed Files

The SELinux process type jabberd_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.

initrc_tmp_t

jabberd_log_t

/var/log/jabber(/.*)?

jabberd_var_lib_t

/var/lib/jabber(/.*)?

/var/lib/jabberd(/.*)?

jabberd_var_run_t

mnt_t

/mnt(/[^/]*)

/mnt(/[^/]*)?

/rhev(/[^/]*)?

/media(/[^/]*)

/media(/[^/]*)?

/etc/rhgb(/.*)?

/media/.hal-.*

/net

/afs

/misc

/rhev

root_t

/

/initrd

tmp_t

/tmp

/usr/tmp

/var/tmp

/var/tmp/vi.recover

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

system-config-selinux is a GUI tool available to customize SELinux policy settings.
