NAME

       traceroute_selinux - Security Enhanced Linux Policy for the traceroute processes

DESCRIPTION

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

       The  traceroute processes execute with the traceroute_t SELinux type. You can check if you have these processes running by executing the ps
       command with the -Z qualifier.

       For example:

       ps -eZ | grep traceroute_t

ENTRYPOINTS

       The traceroute_t SELinux type can be entered via the traceroute_exec_t file type.

       The default entrypoint paths for the traceroute_t domain are the following:

       /bin/tracepath.*,  /bin/traceroute.*,  /usr/bin/tracepath.*,  /usr/bin/traceroute.*,  /usr/sbin/traceroute.*,  /usr/bin/lft,  /usr/bin/mtr,
       /usr/bin/nmap, /usr/sbin/mtr

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

       The following process types are defined for traceroute:

       traceroute_t

       Note: semanage permissive -a traceroute_t can be used to make the process type traceroute_t permissive. SELinux does  not  deny	access	to
       permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

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

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the  authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If  you	want  to  deny	any  process  from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If you want to allow all domains to have the kernel load modules, you must turn on  the	domain_kernel_load_modules  boolean.  Disabled	by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

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

       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 server for the traceroute_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 traceroute_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

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

       The following port types are defined for traceroute:

       traceroute_port_t

       Default Defined Ports:
		 udp 64000-64010

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

       STANDARD FILE CONTEXT

       SELinux	defines  the  file context types for the traceroute, if you wanted to store files with these types in a diffent paths, you need to
       execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t traceroute_exec_t '/srv/traceroute/content(/.*)?'
       restorecon -R -v /srv/mytraceroute_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for traceroute:

       traceroute_exec_t

       - Set files with the traceroute_exec_t type, if you want to transition an executable to the traceroute_t domain.

       Paths:
	    /bin/tracepath.*, /bin/traceroute.*, /usr/bin/tracepath.*, /usr/bin/traceroute.*, /usr/sbin/traceroute.*, /usr/bin/lft,  /usr/bin/mtr,
	    /usr/bin/nmap, /usr/sbin/mtr

       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.

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 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 policy settings.
