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 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 osad_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.

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