6 piranha_fos_selinux - Security Enhanced Linux Policy for the
7 piranha_fos processes
8
10 Security-Enhanced Linux secures the piranha_fos processes via flexible
11 mandatory access control.
12 The piranha_fos processes execute with the piranha_fos_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep piranha_fos_t
20
24 The piranha_fos_t SELinux type can be entered via the
25 piranha_fos_exec_t file type.
26 The default entrypoint paths for the piranha_fos_t domain are the fol‐
28 lowing:
29 /usr/sbin/fos
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 piranha_fos policy is very flexible allowing users to setup their
40 piranha_fos processes in as secure a method as possible.
41 The following process types are defined for piranha_fos:
43 piranha_fos_t
45 Note: semanage permissive -a piranha_fos_t can be used to make the
47 process type piranha_fos_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 piranha_fos policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run piranha_fos with the tight‐
56 est access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.

104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type piranha_fos_t can manage files labeled with
134 the following file types. The paths listed are the default paths for
135 these file types. Note the processes UID still need to have DAC per‐
136 missions.

204 SELinux requires files to have an extended attribute to define the file
205 type.
206 You can see the context of a file using the -Z option to ls
208 Policy governs the access confined processes have to these files.
210 SELinux piranha_fos policy is very flexible allowing users to setup
211 their piranha_fos processes in as secure a method as possible.
212 STANDARD FILE CONTEXT
214 SELinux defines the file context types for the piranha_fos, if you
216 wanted to store files with these types in a diffent paths, you need to
217 execute the semanage command to sepecify alternate labeling and then
218 use restorecon to put the labels on disk.
219 semanage fcontext -a -t piranha_fos_var_run_t '/srv/mypiranha_fos_con‐
221 tent(/.*)?'
222 restorecon -R -v /srv/mypiranha_fos_content
223 Note: SELinux often uses regular expressions to specify labels that
225 match multiple files.
226 The following file types are defined for piranha_fos:
228 piranha_fos_exec_t
232 - Set files with the piranha_fos_exec_t type, if you want to transition
234 an executable to the piranha_fos_t domain.
235 piranha_fos_initrc_exec_t
239 - Set files with the piranha_fos_initrc_exec_t type, if you want to
241 transition an executable to the piranha_fos_initrc_t domain.
242 piranha_fos_tmpfs_t
246 - Set files with the piranha_fos_tmpfs_t type, if you want to store
248 piranha fos files on a tmpfs file system.
249 piranha_fos_var_run_t
253 - Set files with the piranha_fos_var_run_t type, if you want to store
255 the piranha fos files under the /run or /var/run directory.
256 Note: File context can be temporarily modified with the chcon command.
260 If you want to permanently change the file context you need to use the
261 semanage fcontext command. This will modify the SELinux labeling data‐
262 base. You will need to use restorecon to apply the labels.
263
266 semanage fcontext can also be used to manipulate default file context
267 mappings.
268 semanage permissive can also be used to manipulate whether or not a
270 process type is permissive.
271 semanage module can also be used to enable/disable/install/remove pol‐
273 icy modules.
274 semanage boolean can also be used to manipulate the booleans
276 system-config-selinux is a GUI tool available to customize SELinux pol‐
279 icy settings.
