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 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 For example:
17 ps -eZ | grep snort_t
19
23 The snort_t SELinux type can be entered via the snort_exec_t file type.
24 The default entrypoint paths for the snort_t domain are the following:
26 /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 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for snort:
40 snort_t
42 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
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 If you want to deny all system processes and Linux users to use blue‐
57 tooth wireless technology, you must turn on the deny_bluetooth boolean.
58 Enabled by default.
59 setsebool -P deny_bluetooth 1
61 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 setsebool -P fips_mode 1
68
72 The SELinux process type snort_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux snort policy is very flexible allowing users to setup their
151 snort processes in as secure a method as possible.
152 STANDARD FILE CONTEXT
154 SELinux defines the file context types for the snort, if you wanted to
156 store files with these types in a diffent paths, you need to execute
157 the semanage command to specify alternate labeling and then use re‐
158 storecon to put the labels on disk.
159 semanage fcontext -a -t snort_var_run_t '/srv/mysnort_content(/.*)?'
161 restorecon -R -v /srv/mysnort_content
162 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165 The following file types are defined for snort:
167 snort_etc_t
171 - Set files with the snort_etc_t type, if you want to store snort files
173 in the /etc directories.
174 snort_exec_t
178 - Set files with the snort_exec_t type, if you want to transition an
180 executable to the snort_t domain.
181 Paths:
184 /usr/bin/snort, /usr/sbin/snort, /usr/sbin/snort-plain
185 snort_initrc_exec_t
188 - Set files with the snort_initrc_exec_t type, if you want to transi‐
190 tion an executable to the snort_initrc_t domain.
191 snort_log_t
195 - Set files with the snort_log_t type, if you want to treat the data as
197 snort log data, usually stored under the /var/log directory.
198 snort_tmp_t
202 - Set files with the snort_tmp_t type, if you want to store snort tem‐
204 porary files in the /tmp directories.
205 snort_var_run_t
209 - Set files with the snort_var_run_t type, if you want to store the
211 snort files under the /run or /var/run directory.
212 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
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.
