6 osad_selinux - Security Enhanced Linux Policy for the osad processes
7
9 Security-Enhanced Linux secures the osad processes via flexible manda‐
10 tory access control.
11 The osad processes execute with the osad_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 osad_t
19
23 The osad_t SELinux type can be entered via the osad_exec_t file type.
24 The default entrypoint paths for the osad_t domain are the following:
26 /usr/sbin/osad
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 osad policy is very flexible allowing users to setup their osad pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for osad:
40 osad_t
42 Note: semanage permissive -a osad_t can be used to make the process
44 type osad_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. osad
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run osad 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 osad_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.

147 SELinux requires files to have an extended attribute to define the file
148 type.
149 You can see the context of a file using the -Z option to ls
151 Policy governs the access confined processes have to these files.
153 SELinux osad policy is very flexible allowing users to setup their osad
154 processes in as secure a method as possible.
155 STANDARD FILE CONTEXT
157 SELinux defines the file context types for the osad, if you wanted to
159 store files with these types in a different paths, you need to execute
160 the semanage command to specify alternate labeling and then use re‐
161 storecon to put the labels on disk.
162 semanage fcontext -a -t osad_exec_t '/srv/osad/content(/.*)?'
164 restorecon -R -v /srv/myosad_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for osad:
170 osad_exec_t
174 - Set files with the osad_exec_t type, if you want to transition an ex‐
176 ecutable to the osad_t domain.
177 osad_initrc_exec_t
181 - Set files with the osad_initrc_exec_t type, if you want to transition
183 an executable to the osad_initrc_t domain.
184 osad_log_t
188 - Set files with the osad_log_t type, if you want to treat the data as
190 osad log data, usually stored under the /var/log directory.
191 osad_var_run_t
195 - Set files with the osad_var_run_t type, if you want to store the osad
197 files under the /run or /var/run directory.
198 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216 semanage boolean can also be used to manipulate the booleans
218 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
