6 systemd_sysctl_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_sysctl processes
8
10 Security-Enhanced Linux secures the systemd_sysctl processes via flexi‐
11 ble mandatory access control.
12
13 The systemd_sysctl processes execute with the systemd_sysctl_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_sysctl_t
20
21
22
24 The systemd_sysctl_t SELinux type can be entered via the sys‐
25 temd_sysctl_exec_t file type.
26
27 The default entrypoint paths for the systemd_sysctl_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-sysctl
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 systemd_sysctl policy is very flexible allowing users to setup their
40 systemd_sysctl processes in as secure a method as possible.
41
42 The following process types are defined for systemd_sysctl:
43
44 systemd_sysctl_t
45
46 Note: semanage permissive -a systemd_sysctl_t can be used to make the
47 process type systemd_sysctl_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. sys‐
54 temd_sysctl policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run systemd_sysctl with the
56 tightest access possible.
57
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type systemd_sysctl_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

135 SELinux requires files to have an extended attribute to define the file
136 type.
137
138 You can see the context of a file using the -Z option to ls
139
140 Policy governs the access confined processes have to these files.
141 SELinux systemd_sysctl policy is very flexible allowing users to setup
142 their systemd_sysctl processes in as secure a method as possible.
143
144 The following file types are defined for systemd_sysctl:
145
146
147
148 systemd_sysctl_exec_t
149
150 - Set files with the systemd_sysctl_exec_t type, if you want to transi‐
151 tion an executable to the systemd_sysctl_t domain.
152
153
154
155 Note: File context can be temporarily modified with the chcon command.
156 If you want to permanently change the file context you need to use the
157 semanage fcontext command. This will modify the SELinux labeling data‐
158 base. You will need to use restorecon to apply the labels.
159
160
162 semanage fcontext can also be used to manipulate default file context
163 mappings.
164
165 semanage permissive can also be used to manipulate whether or not a
166 process type is permissive.
167
168 semanage module can also be used to enable/disable/install/remove pol‐
169 icy modules.
170
171 semanage boolean can also be used to manipulate the booleans
172
173
174 system-config-selinux is a GUI tool available to customize SELinux pol‐
175 icy settings.
