6 ping_selinux - Security Enhanced Linux Policy for the ping processes
7
9 Security-Enhanced Linux secures the ping processes via flexible manda‐
10 tory access control.
11 The ping processes execute with the ping_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep ping_t
19
23 The ping_t SELinux type can be entered via the ping_exec_t file type.
24 The default entrypoint paths for the ping_t domain are the following:
26 /bin/ping.*, /usr/bin/ping.*, /usr/sbin/fping.*, /usr/sbin/hping2,
28 /usr/sbin/send_arp, /usr/lib/heartbeat/send_arp
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 Policy governs the access confined processes have to files. SELinux
37 ping policy is very flexible allowing users to setup their ping pro‐
38 cesses in as secure a method as possible.
39 The following process types are defined for ping:
41 ping_t, pingd_t
43 Note: semanage permissive -a ping_t can be used to make the process
45 type ping_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
51 SELinux policy is customizable based on least access required. ping
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run ping with the tightest access possible.
54 If you want to allow users to resolve user passwd entries directly from
58 ldap rather then using a sssd server, you must turn on the authlo‐
59 gin_nsswitch_use_ldap boolean. Disabled by default.
60 setsebool -P authlogin_nsswitch_use_ldap 1
62 If you want to allow all domains to execute in fips_mode, you must turn
66 on the fips_mode boolean. Enabled by default.
67 setsebool -P fips_mode 1
69 If you want to allow confined applications to run with kerberos, you
73 must turn on the kerberos_enabled boolean. Enabled by default.
74 setsebool -P kerberos_enabled 1
76 If you want to allow system to run with NIS, you must turn on the
80 nis_enabled boolean. Disabled by default.
81 setsebool -P nis_enabled 1
83 If you want to allow confined applications to use nscd shared memory,
87 you must turn on the nscd_use_shm boolean. Enabled by default.
88 setsebool -P nscd_use_shm 1
90 If you want to allow confined users the ability to execute the ping and
94 traceroute commands, you must turn on the selinuxuser_ping boolean.
95 Enabled by default.
96 setsebool -P selinuxuser_ping 1
98
102 SELinux defines port types to represent TCP and UDP ports.
103 You can see the types associated with a port by using the following
105 command:
106 semanage port -l
108 Policy governs the access confined processes have to these ports.
111 SELinux ping policy is very flexible allowing users to setup their ping
112 processes in as secure a method as possible.
113 The following port types are defined for ping:
115 pingd_port_t
118 Default Defined Ports:
122 tcp 9125
123
125 SELinux requires files to have an extended attribute to define the file
126 type.
127 You can see the context of a file using the -Z option to ls
129 Policy governs the access confined processes have to these files.
131 SELinux ping policy is very flexible allowing users to setup their ping
132 processes in as secure a method as possible.
133 STANDARD FILE CONTEXT
135 SELinux defines the file context types for the ping, if you wanted to
137 store files with these types in a diffent paths, you need to execute
138 the semanage command to sepecify alternate labeling and then use
139 restorecon to put the labels on disk.
140 semanage fcontext -a -t pingd_modules_t '/srv/myping_content(/.*)?'
142 restorecon -R -v /srv/myping_content
143 Note: SELinux often uses regular expressions to specify labels that
145 match multiple files.
146 The following file types are defined for ping:
148 ping_exec_t
152 - Set files with the ping_exec_t type, if you want to transition an
154 executable to the ping_t domain.
155 Paths:
158 /bin/ping.*, /usr/bin/ping.*, /usr/sbin/fping.*, /usr/sbin/hping2,
159 /usr/sbin/send_arp, /usr/lib/heartbeat/send_arp
160 pingd_etc_t
163 - Set files with the pingd_etc_t type, if you want to store pingd files
165 in the /etc directories.
166 pingd_exec_t
170 - Set files with the pingd_exec_t type, if you want to transition an
172 executable to the pingd_t domain.
173 pingd_initrc_exec_t
177 - Set files with the pingd_initrc_exec_t type, if you want to transi‐
179 tion an executable to the pingd_initrc_t domain.
180 pingd_modules_t
184 - Set files with the pingd_modules_t type, if you want to treat the
186 files as pingd modules.
187 Note: File context can be temporarily modified with the chcon command.
191 If you want to permanently change the file context you need to use the
192 semanage fcontext command. This will modify the SELinux labeling data‐
193 base. You will need to use restorecon to apply the labels.
194
197 semanage fcontext can also be used to manipulate default file context
198 mappings.
199 semanage permissive can also be used to manipulate whether or not a
201 process type is permissive.
202 semanage module can also be used to enable/disable/install/remove pol‐
204 icy modules.
205 semanage port can also be used to manipulate the port definitions
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
