dnssec_selinux: Security Enhanced Linux Policy for the dnssec processes

NAME

dnssec_selinux - Security Enhanced Linux Policy for the dnssec processes

DESCRIPTION

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

NSSWITCH DOMAIN

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

The following file types are defined for dnssec:

dnssec_t

- Set files with the dnssec_t type, if you want to treat the files as dnssec data.


Paths:
/etc/unbound/.*.key, /var/named/chroot/etc/rndc.key, /etc/dnssec-trigger/dnssec_trigger_server.key, /etc/rndc.key

dnssec_trigger_exec_t

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

dnssec_trigger_var_run_t

- Set files with the dnssec_trigger_var_run_t type, if you want to store the dnssec trigger files under the /run directory.

Note: File context can be temporarily modified with the chcon command. If you want to permanantly 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 dnssec policy is very flexible allowing users to setup their dnssec processes in as secure a method as possible.

The following port types are defined for dnssec:

dnssec_port_t

Default Defined Ports: tcp 8955

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

The following process types are defined for dnssec:

dnssec_trigger_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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.
