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 allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60
64 The SELinux process type snort_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux snort policy is very flexible allowing users to setup their
143 snort processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the snort, if you wanted to
148 store files with these types in a diffent paths, you need to execute
149 the semanage command to sepecify alternate labeling and then use re‐
150 storecon to put the labels on disk.
151 semanage fcontext -a -t snort_var_run_t '/srv/mysnort_content(/.*)?'
153 restorecon -R -v /srv/mysnort_content
154 Note: SELinux often uses regular expressions to specify labels that
156 match multiple files.
157 The following file types are defined for snort:
159 snort_etc_t
163 - Set files with the snort_etc_t type, if you want to store snort files
165 in the /etc directories.
166 snort_exec_t
170 - Set files with the snort_exec_t type, if you want to transition an
172 executable to the snort_t domain.
173 Paths:
176 /usr/bin/snort, /usr/sbin/snort, /usr/sbin/snort-plain
177 snort_initrc_exec_t
180 - Set files with the snort_initrc_exec_t type, if you want to transi‐
182 tion an executable to the snort_initrc_t domain.
183 snort_log_t
187 - Set files with the snort_log_t type, if you want to treat the data as
189 snort log data, usually stored under the /var/log directory.
190 snort_tmp_t
194 - Set files with the snort_tmp_t type, if you want to store snort tem‐
196 porary files in the /tmp directories.
197 snort_var_run_t
201 - Set files with the snort_var_run_t type, if you want to store the
203 snort files under the /run or /var/run directory.
204 Note: File context can be temporarily modified with the chcon command.
208 If you want to permanently change the file context you need to use the
209 semanage fcontext command. This will modify the SELinux labeling data‐
210 base. You will need to use restorecon to apply the labels.
211
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage boolean can also be used to manipulate the booleans
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
227 icy settings.
