6 cfengine_serverd_selinux - Security Enhanced Linux Policy for the
7 cfengine_serverd processes
8
10 Security-Enhanced Linux secures the cfengine_serverd processes via
11 flexible mandatory access control.
12 The cfengine_serverd processes execute with the cfengine_serverd_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep cfengine_serverd_t
20
24 The cfengine_serverd_t SELinux type can be entered via the
25 cfengine_serverd_exec_t file type.
26 The default entrypoint paths for the cfengine_serverd_t domain are the
28 following:
29 /usr/sbin/cf-serverd
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 cfengine_serverd policy is very flexible allowing users to setup their
40 cfengine_serverd processes in as secure a method as possible.
41 The following process types are defined for cfengine_serverd:
43 cfengine_serverd_t
45 Note: semanage permissive -a cfengine_serverd_t can be used to make the
47 process type cfengine_serverd_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required.
54 cfengine_serverd policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run cfengine_serverd with
56 the tightest access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

97 processes, you must turn on the deny_ptrace boolean. Enabled by
98 default.
99 setsebool -P deny_ptrace 1
101 If you want to allow any process to mmap any file on system with
105 attribute file_type, you must turn on the domain_can_mmap_files bool‐
106 ean. Enabled by default.
107 setsebool -P domain_can_mmap_files 1
109 If you want to allow all domains write to kmsg_device, while kernel is
113 executed with systemd.log_target=kmsg parameter, you must turn on the
114 domain_can_write_kmsg boolean. Disabled by default.
115 setsebool -P domain_can_write_kmsg 1
117 If you want to allow all domains to use other domains file descriptors,
121 you must turn on the domain_fd_use boolean. Enabled by default.
122 setsebool -P domain_fd_use 1
124 If you want to allow all domains to have the kernel load modules, you
128 must turn on the domain_kernel_load_modules boolean. Disabled by
129 default.
130 setsebool -P domain_kernel_load_modules 1
132 If you want to allow all domains to execute in fips_mode, you must turn
136 on the fips_mode boolean. Enabled by default.
137 setsebool -P fips_mode 1
139 If you want to enable reading of urandom for all domains, you must turn
143 on the global_ssp boolean. Disabled by default.
144 setsebool -P global_ssp 1
146 If you want to allow confined applications to run with kerberos, you
150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

171 The SELinux process type cfengine_serverd_t can manage files labeled
172 with the following file types. The paths listed are the default paths
173 for these file types. Note the processes UID still need to have DAC
174 permissions.
175 cfengine_var_lib_t

217 SELinux requires files to have an extended attribute to define the file
218 type.
219 You can see the context of a file using the -Z option to ls
221 Policy governs the access confined processes have to these files.
223 SELinux cfengine_serverd policy is very flexible allowing users to set‐
224 up their cfengine_serverd processes in as secure a method as possible.
225 The following file types are defined for cfengine_serverd:
227 cfengine_serverd_exec_t
231 - Set files with the cfengine_serverd_exec_t type, if you want to tran‐
233 sition an executable to the cfengine_serverd_t domain.
234 Note: File context can be temporarily modified with the chcon command.
238 If you want to permanently change the file context you need to use the
239 semanage fcontext command. This will modify the SELinux labeling data‐
240 base. You will need to use restorecon to apply the labels.
241
244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252 semanage boolean can also be used to manipulate the booleans
254 system-config-selinux is a GUI tool available to customize SELinux pol‐
257 icy settings.
