dnssec_selinux(8) dnssec SELinux Policy documentation dnssec_selinux(8)NAMEdnssec_selinux - Security Enhanced Linux Policy for the dnssec pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the dnssec processes via flexible
mandatory access control.
NSSWITCH DOMAINFILE 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 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 transi‐
tion 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 data‐
base. 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 ps
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 pol‐
icy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
