ping_selinux(8) ping SELinux Policy documentation ping_selinux(8)NAMEping_selinux - Security Enhanced Linux Policy for the ping processes
DESCRIPTION
Security-Enhanced Linux secures the ping processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. ping
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run ping with the tightest access possible.
If you want to control users use of ping and tracerout, you must turn
on the user_ping boolean.
setsebool -P user_ping 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the pingd_t,
ping_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
pingd_t, ping_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 pingd_t, ping_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 ping policy is very flexible allowing users to setup their ping
processes in as secure a method as possible.
The following file types are defined for ping:
ping_exec_t
- Set files with the ping_exec_t type, if you want to transition an
executable to the ping_t domain.
Paths:
/usr/bin/ping.*, /usr/sbin/hping2, /usr/sbin/fping.*, /bin/ping.*,
/usr/sbin/send_arp
pingd_etc_t
- Set files with the pingd_etc_t type, if you want to store pingd files
in the /etc directories.
pingd_exec_t
- Set files with the pingd_exec_t type, if you want to transition an
executable to the pingd_t domain.
pingd_initrc_exec_t
- Set files with the pingd_initrc_exec_t type, if you want to transi‐
tion an executable to the pingd_initrc_t domain.
pingd_modules_t
- Set files with the pingd_modules_t type, if you want to treat the
files as pingd modules.
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 ping policy is very flexible allowing users to setup their ping
processes in as secure a method as possible.
The following port types are defined for ping:
pingd_port_t
Default Defined Ports:
tcp 9125
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
ping policy is very flexible allowing users to setup their ping pro‐
cesses in as secure a method as possible.
The following process types are defined for ping:
ping_t, pingd_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.
