6 nut_upsd_selinux - Security Enhanced Linux Policy for the nut_upsd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the nut_upsd processes via flexible
11 mandatory access control.
12 The nut_upsd processes execute with the nut_upsd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep nut_upsd_t
20
24 The nut_upsd_t SELinux type can be entered via the nut_upsd_exec_t file
25 type.
26 The default entrypoint paths for the nut_upsd_t domain are the follow‐
28 ing:
29 /usr/sbin/upsd
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 nut_upsd policy is very flexible allowing users to setup their nut_upsd
40 processes in as secure a method as possible.
41 The following process types are defined for nut_upsd:
43 nut_upsd_t, nut_upsdrvctl_t
45 Note: semanage permissive -a nut_upsd_t can be used to make the process
47 type nut_upsd_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.
54 nut_upsd policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run nut_upsd with the tightest ac‐
56 cess possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type nut_upsd_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux nut_upsd policy is very flexible allowing users to setup their
138 nut_upsd processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the nut_upsd, if you wanted
143 to store files with these types in a diffent paths, you need to execute
144 the semanage command to specify alternate labeling and then use re‐
145 storecon to put the labels on disk.
146 semanage fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsd_con‐
148 tent(/.*)?'
149 restorecon -R -v /srv/mynut_upsd_content
150 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153 The following file types are defined for nut_upsd:
155 nut_upsd_exec_t
159 - Set files with the nut_upsd_exec_t type, if you want to transition an
161 executable to the nut_upsd_t domain.
162 nut_upsd_tmp_t
166 - Set files with the nut_upsd_tmp_t type, if you want to store nut upsd
168 temporary files in the /tmp directories.
169 nut_upsdrvctl_exec_t
173 - Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
175 tion an executable to the nut_upsdrvctl_t domain.
176 Paths:
179 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
180 nut_upsdrvctl_tmp_t
183 - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
185 upsdrvctl temporary files in the /tmp directories.
186 Note: File context can be temporarily modified with the chcon command.
190 If you want to permanently change the file context you need to use the
191 semanage fcontext command. This will modify the SELinux labeling data‐
192 base. You will need to use restorecon to apply the labels.
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage boolean can also be used to manipulate the booleans
206 system-config-selinux is a GUI tool available to customize SELinux pol‐
209 icy settings.
