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 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 For example:
18 ps -eZ | grep traceroute_t
20
24 The traceroute_t SELinux type can be entered via the traceroute_exec_t
25 file type.
26 The default entrypoint paths for the traceroute_t domain are the fol‐
28 lowing:
29 /bin/tracepath.*, /bin/traceroute.*, /usr/bin/traceroute.*,
31 /usr/sbin/traceroute.*, /usr/bin/lft, /usr/bin/nmap
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 traceroute policy is very flexible allowing users to setup their
41 traceroute processes in as secure a method as possible.
42 The following process types are defined for traceroute:
44 traceroute_t
46 Note: semanage permissive -a traceroute_t can be used to make the
48 process type traceroute_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. tracer‐
55 oute policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run traceroute with the tightest
57 access possible.
58 If you want to allow all daemons the ability to read/write terminals,
62 you must turn on the allow_daemons_use_tty boolean. Disabled by
63 default.
64 setsebool -P allow_daemons_use_tty 1
66 If you want to allow all domains to use other domains file descriptors,
70 you must turn on the allow_domain_fd_use boolean. Enabled by default.
71 setsebool -P allow_domain_fd_use 1
73 If you want to allow confined applications to run with kerberos, you
77 must turn on the allow_kerberos boolean. Enabled by default.
78 setsebool -P allow_kerberos 1
80 If you want to allow sysadm to debug or ptrace all processes, you must
84 turn on the allow_ptrace boolean. Disabled by default.
85 setsebool -P allow_ptrace 1
87 If you want to allow system to run with NIS, you must turn on the
91 allow_ypbind boolean. Disabled by default.
92 setsebool -P allow_ypbind 1
94 If you want to allow all domains to have the kernel load modules, you
98 must turn on the domain_kernel_load_modules boolean. Disabled by
99 default.
100 setsebool -P domain_kernel_load_modules 1
102 If you want to allow all domains to execute in fips_mode, you must turn
106 on the fips_mode boolean. Enabled by default.
107 setsebool -P fips_mode 1
109 If you want to enable reading of urandom for all domains, you must turn
113 on the global_ssp boolean. Disabled by default.
114 setsebool -P global_ssp 1
116 If you want to allow confined applications to use nscd shared memory,
120 you must turn on the nscd_use_shm boolean. Enabled by default.
121 setsebool -P nscd_use_shm 1
123 If you want to control users use of ping and traceroute, you must turn
127 on the user_ping boolean. Enabled by default.
128 setsebool -P user_ping 1
130
134 SELinux defines port types to represent TCP and UDP ports.
135 You can see the types associated with a port by using the following
137 command:
138 semanage port -l
140 Policy governs the access confined processes have to these ports.
143 SELinux traceroute policy is very flexible allowing users to setup
144 their traceroute processes in as secure a method as possible.
145 The following port types are defined for traceroute:
147 traceroute_port_t
150 Default Defined Ports:
154 udp 64000-64010
155
157 The SELinux process type traceroute_t can manage files labeled with the
158 following file types. The paths listed are the default paths for these
159 file types. Note the processes UID still need to have DAC permissions.
160 initrc_tmp_t
162 mnt_t
165 /mnt(/[^/]*)
167 /mnt(/[^/]*)?
168 /rhev(/[^/]*)?
169 /media(/[^/]*)
170 /media(/[^/]*)?
171 /etc/rhgb(/.*)?
172 /media/.hal-.*
173 /net
174 /afs
175 /rhev
176 /misc
177 tmp_t
179 /tmp
181 /usr/tmp
182 /var/tmp
183 /tmp-inst
184 /var/tmp-inst
185 /var/tmp/vi.recover
186
189 SELinux requires files to have an extended attribute to define the file
190 type.
191 You can see the context of a file using the -Z option to ls
193 Policy governs the access confined processes have to these files.
195 SELinux traceroute policy is very flexible allowing users to setup
196 their traceroute processes in as secure a method as possible.
197 The following file types are defined for traceroute:
199 traceroute_exec_t
203 - Set files with the traceroute_exec_t type, if you want to transition
205 an executable to the traceroute_t domain.
206 Paths:
209 /bin/tracepath.*, /bin/traceroute.*, /usr/bin/traceroute.*,
210 /usr/sbin/traceroute.*, /usr/bin/lft, /usr/bin/nmap
211 Note: File context can be temporarily modified with the chcon command.
214 If you want to permanently change the file context you need to use the
215 semanage fcontext command. This will modify the SELinux labeling data‐
216 base. You will need to use restorecon to apply the labels.
217
220 semanage fcontext can also be used to manipulate default file context
221 mappings.
222 semanage permissive can also be used to manipulate whether or not a
224 process type is permissive.
225 semanage module can also be used to enable/disable/install/remove pol‐
227 icy modules.
228 semanage port can also be used to manipulate the port definitions
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
