zebra_selinux(8) zebra SELinux Policy documentation zebra_selinux(8)NAMEzebra_selinux - Security Enhanced Linux Policy for the zebra processes
DESCRIPTION
Security-Enhanced Linux secures the zebra processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. zebra
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run zebra with the tightest access possible.
If you want to allow zebra daemon to write it configuration file, you
must turn on the allow_zebra_write_config boolean.
setsebool -P allow_zebra_write_config 1
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 zebra policy is very flexible allowing users to setup their
zebra processes in as secure a method as possible.
The following file types are defined for zebra:
zebra_conf_t
- Set files with the zebra_conf_t type, if you want to treat the files
as zebra configuration data, usually stored under the /etc directory.
Paths:
/etc/zebra(/.*)?, /etc/quagga(/.*)?
zebra_exec_t
- Set files with the zebra_exec_t type, if you want to transition an
executable to the zebra_t domain.
Paths:
/usr/sbin/zebra, /usr/sbin/rip.*, /usr/sbin/bgpd, /usr/sbin/ospf.*
zebra_initrc_exec_t
- Set files with the zebra_initrc_exec_t type, if you want to transi‐
tion an executable to the zebra_initrc_t domain.
Paths:
/etc/rc.d/init.d/ripd, /etc/rc.d/init.d/ripngd,
/etc/rc.d/init.d/zebra, /etc/rc.d/init.d/bgpd,
/etc/rc.d/init.d/ospf6d, /etc/rc.d/init.d/ospfd
zebra_log_t
- Set files with the zebra_log_t type, if you want to treat the data as
zebra log data, usually stored under the /var/log directory.
Paths:
/var/log/quagga(/.*)?, /var/log/zebra(/.*)?
zebra_tmp_t
- Set files with the zebra_tmp_t type, if you want to store zebra tem‐
porary files in the /tmp directories.
zebra_var_run_t
- Set files with the zebra_var_run_t type, if you want to store the
zebra files under the /run directory.
Paths:
/var/run/.zserv, /var/run/.zebra, /var/run/quagga(/.*)?
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 zebra policy is very flexible allowing users to setup their
zebra processes in as secure a method as possible.
The following port types are defined for zebra:
zebra_port_t
Default Defined Ports:
tcp 2600-2604,2606
udp 2600-2604,2606
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
zebra policy is very flexible allowing users to setup their zebra pro‐
cesses in as secure a method as possible.
The following process types are defined for zebra:
zebra_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.
