6 snort_selinux - Security Enhanced Linux Policy for the snort processes
7
9 Security-Enhanced Linux secures the snort processes via flexible manda‐
10 tory access control.
11
12 The snort processes execute with the snort_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep snort_t
19
20
21
23 The snort_t SELinux type can be entered via the snort_exec_t file type.
24
25 The default entrypoint paths for the snort_t domain are the following:
26
27 /usr/bin/snort, /usr/sbin/snort, /usr/sbin/snort-plain
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 snort policy is very flexible allowing users to setup their snort pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for snort:
40
41 snort_t
42
43 Note: semanage permissive -a snort_t can be used to make the process
44 type snort_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. snort
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run snort with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89
90
91
93 The SELinux process type snort_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

150 SELinux requires files to have an extended attribute to define the file
151 type.
152
153 You can see the context of a file using the -Z option to ls
154
155 Policy governs the access confined processes have to these files.
156 SELinux snort policy is very flexible allowing users to setup their
157 snort processes in as secure a method as possible.
158
159 STANDARD FILE CONTEXT
160
161 SELinux defines the file context types for the snort, if you wanted to
162 store files with these types in a diffent paths, you need to execute
163 the semanage command to sepecify alternate labeling and then use
164 restorecon to put the labels on disk.
165
166 semanage fcontext -a -t snort_var_run_t '/srv/mysnort_content(/.*)?'
167 restorecon -R -v /srv/mysnort_content
168
169 Note: SELinux often uses regular expressions to specify labels that
170 match multiple files.
171
172 The following file types are defined for snort:
173
174
175
176 snort_etc_t
177
178 - Set files with the snort_etc_t type, if you want to store snort files
179 in the /etc directories.
180
181
182
183 snort_exec_t
184
185 - Set files with the snort_exec_t type, if you want to transition an
186 executable to the snort_t domain.
187
188
189 Paths:
190 /usr/bin/snort, /usr/sbin/snort, /usr/sbin/snort-plain
191
192
193 snort_initrc_exec_t
194
195 - Set files with the snort_initrc_exec_t type, if you want to transi‐
196 tion an executable to the snort_initrc_t domain.
197
198
199
200 snort_log_t
201
202 - Set files with the snort_log_t type, if you want to treat the data as
203 snort log data, usually stored under the /var/log directory.
204
205
206
207 snort_tmp_t
208
209 - Set files with the snort_tmp_t type, if you want to store snort tem‐
210 porary files in the /tmp directories.
211
212
213
214 snort_var_run_t
215
216 - Set files with the snort_var_run_t type, if you want to store the
217 snort files under the /run or /var/run directory.
218
219
220
221 Note: File context can be temporarily modified with the chcon command.
222 If you want to permanently change the file context you need to use the
223 semanage fcontext command. This will modify the SELinux labeling data‐
224 base. You will need to use restorecon to apply the labels.
225
226
228 semanage fcontext can also be used to manipulate default file context
229 mappings.
230
231 semanage permissive can also be used to manipulate whether or not a
232 process type is permissive.
233
234 semanage module can also be used to enable/disable/install/remove pol‐
235 icy modules.
236
237 semanage boolean can also be used to manipulate the booleans
238
239
240 system-config-selinux is a GUI tool available to customize SELinux pol‐
241 icy settings.
