6 foghorn_selinux - Security Enhanced Linux Policy for the foghorn pro‐
7 cesses
8
10 Security-Enhanced Linux secures the foghorn processes via flexible
11 mandatory access control.
12 The foghorn processes execute with the foghorn_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep foghorn_t
20
24 The foghorn_t SELinux type can be entered via the foghorn_exec_t file
25 type.
26 The default entrypoint paths for the foghorn_t domain are the follow‐
28 ing:
29 /usr/sbin/foghorn
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 foghorn policy is very flexible allowing users to setup their foghorn
40 processes in as secure a method as possible.
41 The following process types are defined for foghorn:
43 foghorn_t
45 Note: semanage permissive -a foghorn_t can be used to make the process
47 type foghorn_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. foghorn
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run foghorn with the tightest access possi‐
56 ble.
57 If you want to allow cluster administrative cluster domains memcheck-
61 amd64- to use executable memory, you must turn on the clus‐
62 ter_use_execmem boolean. Disabled by default.
63 setsebool -P cluster_use_execmem 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type foghorn_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux foghorn policy is very flexible allowing users to setup their
143 foghorn processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the foghorn, if you wanted
148 to store files with these types in a diffent paths, you need to execute
149 the semanage command to sepecify alternate labeling and then use
150 restorecon to put the labels on disk.
151 semanage fcontext -a -t foghorn_var_run_t '/srv/myfoghorn_con‐
153 tent(/.*)?'
154 restorecon -R -v /srv/myfoghorn_content
155 Note: SELinux often uses regular expressions to specify labels that
157 match multiple files.
158 The following file types are defined for foghorn:
160 foghorn_exec_t
164 - Set files with the foghorn_exec_t type, if you want to transition an
166 executable to the foghorn_t domain.
167 foghorn_initrc_exec_t
171 - Set files with the foghorn_initrc_exec_t type, if you want to transi‐
173 tion an executable to the foghorn_initrc_t domain.
174 foghorn_tmpfs_t
178 - Set files with the foghorn_tmpfs_t type, if you want to store foghorn
180 files on a tmpfs file system.
181 foghorn_var_log_t
185 - Set files with the foghorn_var_log_t type, if you want to treat the
187 data as foghorn var log data, usually stored under the /var/log direc‐
188 tory.
189 foghorn_var_run_t
193 - Set files with the foghorn_var_run_t type, if you want to store the
195 foghorn files under the /run or /var/run directory.
196 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage boolean can also be used to manipulate the booleans
216 system-config-selinux is a GUI tool available to customize SELinux pol‐
219 icy settings.
