6 psad_selinux - Security Enhanced Linux Policy for the psad processes
7
9 Security-Enhanced Linux secures the psad processes via flexible manda‐
10 tory access control.
11 The psad processes execute with the psad_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep psad_t
19
23 The psad_t SELinux type can be entered via the psad_exec_t file type.
24 The default entrypoint paths for the psad_t domain are the following:
26 /usr/sbin/psad
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 psad policy is very flexible allowing users to setup their psad pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for psad:
40 psad_t
42 Note: semanage permissive -a psad_t can be used to make the process
44 type psad_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. psad
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run psad with the tightest access possible.
53 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59 setsebool -P daemons_dontaudit_scheduling 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 If you want to allow system to run with NIS, you must turn on the
72 nis_enabled boolean. Disabled by default.
73 setsebool -P nis_enabled 1
75
79 The SELinux process type psad_t can manage files labeled with the fol‐
80 lowing file types. The paths listed are the default paths for these
81 file types. Note the processes UID still need to have DAC permissions.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux psad policy is very flexible allowing users to setup their psad
149 processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the psad, if you wanted to
154 store files with these types in a different paths, you need to execute
155 the semanage command to specify alternate labeling and then use re‐
156 storecon to put the labels on disk.
157 semanage fcontext -a -t psad_exec_t '/srv/psad/content(/.*)?'
159 restorecon -R -v /srv/mypsad_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for psad:
165 psad_etc_t
169 - Set files with the psad_etc_t type, if you want to store psad files
171 in the /etc directories.
172 psad_exec_t
176 - Set files with the psad_exec_t type, if you want to transition an ex‐
178 ecutable to the psad_t domain.
179 psad_initrc_exec_t
183 - Set files with the psad_initrc_exec_t type, if you want to transition
185 an executable to the psad_initrc_t domain.
186 psad_tmp_t
190 - Set files with the psad_tmp_t type, if you want to store psad tempo‐
192 rary files in the /tmp directories.
193 psad_var_lib_t
197 - Set files with the psad_var_lib_t type, if you want to store the psad
199 files under the /var/lib directory.
200 psad_var_log_t
204 - Set files with the psad_var_log_t type, if you want to treat the data
206 as psad var log data, usually stored under the /var/log directory.
207 psad_var_run_t
211 - Set files with the psad_var_run_t type, if you want to store the psad
213 files under the /run or /var/run directory.
214 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232 semanage boolean can also be used to manipulate the booleans
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
