6 cfengine_monitord_selinux - Security Enhanced Linux Policy for the
7 cfengine_monitord processes
8
10 Security-Enhanced Linux secures the cfengine_monitord processes via
11 flexible mandatory access control.
12 The cfengine_monitord processes execute with the cfengine_monitord_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_monitord_t
20
24 The cfengine_monitord_t SELinux type can be entered via the file_type,
25 unlabeled_t, proc_type, filesystem_type, mtrr_device_t, cfengine_moni‐
26 tord_exec_t, sysctl_type file types.
27 The default entrypoint paths for the cfengine_monitord_t domain are the
29 following:
30 all files on the system, /dev/cpu/mtrr, /usr/sbin/cf-monitord
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 cfengine_monitord policy is very flexible allowing users to setup their
41 cfengine_monitord processes in as secure a method as possible.
42 The following process types are defined for cfengine_monitord:
44 cfengine_monitord_t
46 Note: semanage permissive -a cfengine_monitord_t can be used to make
48 the process type cfengine_monitord_t permissive. SELinux does not deny
49 access to permissive process types, but the AVC (SELinux denials) mes‐
50 sages are still generated.
51
54 SELinux policy is customizable based on least access required.
55 cfengine_monitord policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run cfengine_monitord with
57 the tightest access possible.
58 If you want to allow all daemons to write corefiles to /, you must turn
62 on the allow_daemons_dump_core boolean. Disabled by default.
63 setsebool -P allow_daemons_dump_core 1
65 If you want to allow all daemons to use tcp wrappers, you must turn on

87 If you want to allow unconfined executables to make their heap memory
91 executable. Doing this is a really bad idea. Probably indicates a
92 badly coded executable, but could indicate an attack. This executable
93 should be reported in bugzilla, you must turn on the allow_execheap
94 boolean. Disabled by default.
95 setsebool -P allow_execheap 1
97 If you want to allow unconfined executables to map a memory region as
101 both executable and writable, this is dangerous and the executable
102 should be reported in bugzilla), you must turn on the allow_execmem
103 boolean. Enabled by default.
104 setsebool -P allow_execmem 1
106 If you want to allow all unconfined executables to use libraries
110 requiring text relocation that are not labeled textrel_shlib_t), you
111 must turn on the allow_execmod boolean. Enabled by default.
112 setsebool -P allow_execmod 1
114 If you want to allow unconfined executables to make their stack exe‐
118 cutable. This should never, ever be necessary. Probably indicates a
119 badly coded executable, but could indicate an attack. This executable
120 should be reported in bugzilla), you must turn on the allow_execstack
121 boolean. Enabled by default.
122 setsebool -P allow_execstack 1
124 If you want to allow confined applications to run with kerberos, you
128 must turn on the allow_kerberos boolean. Enabled by default.
129 setsebool -P allow_kerberos 1
131 If you want to allow sysadm to debug or ptrace all processes, you must
135 turn on the allow_ptrace boolean. Disabled by default.
136 setsebool -P allow_ptrace 1
138 If you want to allow system to run with NIS, you must turn on the
142 allow_ypbind boolean. Disabled by default.
143 setsebool -P allow_ypbind 1
145 If you want to enable cluster mode for daemons, you must turn on the
149 daemons_enable_cluster_mode boolean. Disabled by default.
150 setsebool -P daemons_enable_cluster_mode 1
152 If you want to allow all domains to have the kernel load modules, you
156 must turn on the domain_kernel_load_modules boolean. Disabled by
157 default.
158 setsebool -P domain_kernel_load_modules 1
160 If you want to allow all domains to execute in fips_mode, you must turn
164 on the fips_mode boolean. Enabled by default.
165 setsebool -P fips_mode 1
167 If you want to enable reading of urandom for all domains, you must turn
171 on the global_ssp boolean. Disabled by default.
172 setsebool -P global_ssp 1
174 If you want to enable support for upstart as the init program, you must
178 turn on the init_upstart boolean. Enabled by default.
179 setsebool -P init_upstart 1
181 If you want to allow certain domains to map low memory in the kernel,
185 you must turn on the mmap_low_allowed boolean. Disabled by default.
186 setsebool -P mmap_low_allowed 1
188 If you want to allow confined applications to use nscd shared memory,
192 you must turn on the nscd_use_shm boolean. Enabled by default.
193 setsebool -P nscd_use_shm 1
195 If you want to boolean to determine whether the system permits loading
199 policy, setting enforcing mode, and changing boolean values. Set this
200 to true and you have to reboot to set it back, you must turn on the
201 secure_mode_policyload boolean. Disabled by default.
202 setsebool -P secure_mode_policyload 1
204 If you want to support X userspace object manager, you must turn on the
208 xserver_object_manager boolean. Disabled by default.
209 setsebool -P xserver_object_manager 1

215 The SELinux process type cfengine_monitord_t can manage files labeled
216 with the following file types. The paths listed are the default paths
217 for these file types. Note the processes UID still need to have DAC
218 permissions.
219 file_type
221 all files on the system
223
226 SELinux requires files to have an extended attribute to define the file
227 type.
228 You can see the context of a file using the -Z option to ls
230 Policy governs the access confined processes have to these files.
232 SELinux cfengine_monitord policy is very flexible allowing users to
233 setup their cfengine_monitord processes in as secure a method as possi‐
234 ble.
235 The following file types are defined for cfengine_monitord:
237 cfengine_monitord_exec_t
241 - Set files with the cfengine_monitord_exec_t type, if you want to
243 transition an executable to the cfengine_monitord_t domain.
244 Note: File context can be temporarily modified with the chcon command.
248 If you want to permanently change the file context you need to use the
249 semanage fcontext command. This will modify the SELinux labeling data‐
250 base. You will need to use restorecon to apply the labels.
251
254 semanage fcontext can also be used to manipulate default file context
255 mappings.
256 semanage permissive can also be used to manipulate whether or not a
258 process type is permissive.
259 semanage module can also be used to enable/disable/install/remove pol‐
261 icy modules.
262 semanage boolean can also be used to manipulate the booleans
264 system-config-selinux is a GUI tool available to customize SELinux pol‐
267 icy settings.
