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 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 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1
89
93 The SELinux process type psad_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.

141 SELinux requires files to have an extended attribute to define the file
142 type.
143 You can see the context of a file using the -Z option to ls
145 Policy governs the access confined processes have to these files.
147 SELinux psad policy is very flexible allowing users to setup their psad
148 processes in as secure a method as possible.
149 STANDARD FILE CONTEXT
151 SELinux defines the file context types for the psad, if you wanted to
153 store files with these types in a diffent paths, you need to execute
154 the semanage command to sepecify alternate labeling and then use
155 restorecon to put the labels on disk.
156 semanage fcontext -a -t psad_tmp_t '/srv/mypsad_content(/.*)?'
158 restorecon -R -v /srv/mypsad_content
159 Note: SELinux often uses regular expressions to specify labels that
161 match multiple files.
162 The following file types are defined for psad:
164 psad_etc_t
168 - Set files with the psad_etc_t type, if you want to store psad files
170 in the /etc directories.
171 psad_exec_t
175 - Set files with the psad_exec_t type, if you want to transition an
177 executable to the psad_t domain.
178 psad_initrc_exec_t
182 - Set files with the psad_initrc_exec_t type, if you want to transition
184 an executable to the psad_initrc_t domain.
185 psad_tmp_t
189 - Set files with the psad_tmp_t type, if you want to store psad tempo‐
191 rary files in the /tmp directories.
192 psad_var_lib_t
196 - Set files with the psad_var_lib_t type, if you want to store the psad
198 files under the /var/lib directory.
199 psad_var_log_t
203 - Set files with the psad_var_log_t type, if you want to treat the data
205 as psad var log data, usually stored under the /var/log directory.
206 psad_var_run_t
210 - Set files with the psad_var_run_t type, if you want to store the psad
212 files under the /run or /var/run directory.
213 Note: File context can be temporarily modified with the chcon command.
217 If you want to permanently change the file context you need to use the
218 semanage fcontext command. This will modify the SELinux labeling data‐
219 base. You will need to use restorecon to apply the labels.
220
223 semanage fcontext can also be used to manipulate default file context
224 mappings.
225 semanage permissive can also be used to manipulate whether or not a
227 process type is permissive.
228 semanage module can also be used to enable/disable/install/remove pol‐
230 icy modules.
231 semanage boolean can also be used to manipulate the booleans
233 system-config-selinux is a GUI tool available to customize SELinux pol‐
236 icy settings.
