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 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 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 The SELinux process type psad_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

116 SELinux requires files to have an extended attribute to define the file
117 type.
118 You can see the context of a file using the -Z option to ls
120 Policy governs the access confined processes have to these files.
122 SELinux psad policy is very flexible allowing users to setup their psad
123 processes in as secure a method as possible.
124 STANDARD FILE CONTEXT
126 SELinux defines the file context types for the psad, if you wanted to
128 store files with these types in a diffent paths, you need to execute
129 the semanage command to sepecify alternate labeling and then use
130 restorecon to put the labels on disk.
131 semanage fcontext -a -t psad_tmp_t '/srv/mypsad_content(/.*)?'
133 restorecon -R -v /srv/mypsad_content
134 Note: SELinux often uses regular expressions to specify labels that
136 match multiple files.
137 The following file types are defined for psad:
139 psad_etc_t
143 - Set files with the psad_etc_t type, if you want to store psad files
145 in the /etc directories.
146 psad_exec_t
150 - Set files with the psad_exec_t type, if you want to transition an
152 executable to the psad_t domain.
153 psad_initrc_exec_t
157 - Set files with the psad_initrc_exec_t type, if you want to transition
159 an executable to the psad_initrc_t domain.
160 psad_tmp_t
164 - Set files with the psad_tmp_t type, if you want to store psad tempo‐
166 rary files in the /tmp directories.
167 psad_var_lib_t
171 - Set files with the psad_var_lib_t type, if you want to store the psad
173 files under the /var/lib directory.
174 psad_var_log_t
178 - Set files with the psad_var_log_t type, if you want to treat the data
180 as psad var log data, usually stored under the /var/log directory.
181 psad_var_run_t
185 - Set files with the psad_var_run_t type, if you want to store the psad
187 files under the /run or /var/run directory.
188 Note: File context can be temporarily modified with the chcon command.
192 If you want to permanently change the file context you need to use the
193 semanage fcontext command. This will modify the SELinux labeling data‐
194 base. You will need to use restorecon to apply the labels.
195
198 semanage fcontext can also be used to manipulate default file context
199 mappings.
200 semanage permissive can also be used to manipulate whether or not a
202 process type is permissive.
203 semanage module can also be used to enable/disable/install/remove pol‐
205 icy modules.
206 semanage boolean can also be used to manipulate the booleans
208 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
