6 traceroute_selinux - Security Enhanced Linux Policy for the traceroute
7 processes
8
10 Security-Enhanced Linux secures the traceroute processes via flexible
11 mandatory access control.
12
13 The traceroute processes execute with the traceroute_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep traceroute_t
20
21
22
24 The traceroute_t SELinux type can be entered via the traceroute_exec_t
25 file type.
26
27 The default entrypoint paths for the traceroute_t domain are the fol‐
28 lowing:
29
30 /bin/tracepath.*, /bin/traceroute.*, /usr/bin/tracepath.*,
31 /usr/bin/traceroute.*, /usr/sbin/traceroute.*, /usr/bin/lft,
32 /usr/bin/mtr, /usr/bin/nmap, /usr/sbin/mtr
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 traceroute policy is very flexible allowing users to setup their
42 traceroute processes in as secure a method as possible.
43
44 The following process types are defined for traceroute:
45
46 traceroute_t
47
48 Note: semanage permissive -a traceroute_t can be used to make the
49 process type traceroute_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required. tracer‐
56 oute policy is extremely flexible and has several booleans that allow
57 you to manipulate the policy and run traceroute with the tightest
58 access possible.
59
60
61
62 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65
66 setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to allow confined applications to run with kerberos, you
78 must turn on the kerberos_enabled boolean. Enabled by default.
79
80 setsebool -P kerberos_enabled 1
81
82
83
84 If you want to allow system to run with NIS, you must turn on the
85 nis_enabled boolean. Disabled by default.
86
87 setsebool -P nis_enabled 1
88
89
90
91 If you want to allow confined applications to use nscd shared memory,
92 you must turn on the nscd_use_shm boolean. Disabled by default.
93
94 setsebool -P nscd_use_shm 1
95
96
97
98 If you want to allow confined users the ability to execute the ping and
99 traceroute commands, you must turn on the selinuxuser_ping boolean.
100 Enabled by default.
101
102 setsebool -P selinuxuser_ping 1
103
104
105
107 SELinux defines port types to represent TCP and UDP ports.
108
109 You can see the types associated with a port by using the following
110 command:
111
112 semanage port -l
113
114
115 Policy governs the access confined processes have to these ports.
116 SELinux traceroute policy is very flexible allowing users to setup
117 their traceroute processes in as secure a method as possible.
118
119 The following port types are defined for traceroute:
120
121
122 traceroute_port_t
123
124
125
126 Default Defined Ports:
127 udp 64000-64010
128
130 SELinux requires files to have an extended attribute to define the file
131 type.
132
133 You can see the context of a file using the -Z option to ls
134
135 Policy governs the access confined processes have to these files.
136 SELinux traceroute policy is very flexible allowing users to setup
137 their traceroute processes in as secure a method as possible.
138
139 The following file types are defined for traceroute:
140
141
142
143 traceroute_exec_t
144
145 - Set files with the traceroute_exec_t type, if you want to transition
146 an executable to the traceroute_t domain.
147
148
149 Paths:
150 /bin/tracepath.*, /bin/traceroute.*, /usr/bin/tracepath.*,
151 /usr/bin/traceroute.*, /usr/sbin/traceroute.*, /usr/bin/lft,
152 /usr/bin/mtr, /usr/bin/nmap, /usr/sbin/mtr
153
154
155 Note: File context can be temporarily modified with the chcon command.
156 If you want to permanently change the file context you need to use the
157 semanage fcontext command. This will modify the SELinux labeling data‐
158 base. You will need to use restorecon to apply the labels.
159
160
162 semanage fcontext can also be used to manipulate default file context
163 mappings.
164
165 semanage permissive can also be used to manipulate whether or not a
166 process type is permissive.
167
168 semanage module can also be used to enable/disable/install/remove pol‐
169 icy modules.
170
171 semanage port can also be used to manipulate the port definitions
172
173 semanage boolean can also be used to manipulate the booleans
174
175
176 system-config-selinux is a GUI tool available to customize SELinux pol‐
177 icy settings.
