openvpn_selinux(8) openvpn SELinux Policy documentation openvpn_selinux(8)NAMEopenvpn_selinux - Security Enhanced Linux Policy for the openvpn pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the openvpn processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. openvpn
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run openvpn with the tightest access possi‐
ble.
If you want to allow openvpn to read home directorie, you must turn on
the openvpn_enable_homedirs boolean.
setsebool -P openvpn_enable_homedirs 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the open‐
vpn_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
openvpn_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the openvpn_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
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 openvpn policy is very flexible allowing users to setup their
openvpn processes in as secure a method as possible.
The following file types are defined for openvpn:
openvpn_etc_rw_t
- Set files with the openvpn_etc_rw_t type, if you want to treat the
files as openvpn etc read/write content.
openvpn_etc_t
- Set files with the openvpn_etc_t type, if you want to store openvpn
files in the /etc directories.
openvpn_exec_t
- Set files with the openvpn_exec_t type, if you want to transition an
executable to the openvpn_t domain.
openvpn_initrc_exec_t
- Set files with the openvpn_initrc_exec_t type, if you want to transi‐
tion an executable to the openvpn_initrc_t domain.
openvpn_tmp_t
- Set files with the openvpn_tmp_t type, if you want to store openvpn
temporary files in the /tmp directories.
openvpn_var_log_t
- Set files with the openvpn_var_log_t type, if you want to treat the
data as openvpn var log data, usually stored under the /var/log direc‐
tory.
openvpn_var_run_t
- Set files with the openvpn_var_run_t type, if you want to store the
openvpn 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 openvpn policy is very flexible allowing users to setup their
openvpn processes in as secure a method as possible.
The following port types are defined for openvpn:
openvpn_port_t
Default Defined Ports:
tcp 1194
udp 1194
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
openvpn policy is very flexible allowing users to setup their openvpn
processes in as secure a method as possible.
The following process types are defined for openvpn:
openvpn_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
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
