NAME

pingd_selinux - Security Enhanced Linux Policy for the pingd processes  

DESCRIPTION

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

 

BOOLEANS

SELinux policy is customizable based on least access required. pingd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pingd with the tightest access possible.

If you want to allow confined users the ability to execute the ping and traceroute commands, you must turn on the selinuxuser_ping boolean.

setsebool -P selinuxuser_ping 1

 

NSSWITCH DOMAIN

If you want to allow users to resolve user passwd entries directly from ldap rather then 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 kerberos_enabled boolean.

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

The following file types are defined for pingd:

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 transition 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 permanently 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 pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible.

The following port types are defined for pingd:

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

The following process types are defined for pingd:

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.

 

MANAGED FILES

The SELinux user type pingd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

 

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
