6 nagios_eventhandler_plugin_selinux - Security Enhanced Linux Policy for
7 the nagios_eventhandler_plugin processes
8
10 Security-Enhanced Linux secures the nagios_eventhandler_plugin pro‐
11 cesses via flexible mandatory access control.
12 The nagios_eventhandler_plugin processes execute with the nagios_even‐
14 thandler_plugin_t SELinux type. You can check if you have these pro‐
15 cesses running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep nagios_eventhandler_plugin_t
20
24 The nagios_eventhandler_plugin_t SELinux type can be entered via the
25 nagios_eventhandler_plugin_exec_t, file_type, unlabeled_t, proc_type,
26 filesystem_type, mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the nagios_eventhandler_plugin_t
29 domain are the following:
30 /usr/lib(64)?/nagios/plugins/eventhandlers(/.*)?, all files on the sys‐
32 tem, /dev/cpu/mtrr
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 nagios_eventhandler_plugin policy is very flexible allowing users to
42 setup their nagios_eventhandler_plugin processes in as secure a method
43 as possible.
44 The following process types are defined for nagios_eventhandler_plugin:
46 nagios_eventhandler_plugin_t
48 Note: semanage permissive -a nagios_eventhandler_plugin_t can be used
50 to make the process type nagios_eventhandler_plugin_t permissive.
51 SELinux does not deny access to permissive process types, but the AVC
52 (SELinux denials) messages are still generated.
53
56 SELinux policy is customizable based on least access required.
57 nagios_eventhandler_plugin policy is extremely flexible and has several
58 booleans that allow you to manipulate the policy and run nagios_even‐
59 thandler_plugin with the tightest access possible.
60 If you want to allow all domains to use other domains file descriptors,
64 you must turn on the allow_domain_fd_use boolean. Enabled by default.
65 setsebool -P allow_domain_fd_use 1
67 If you want to allow unconfined executables to make their heap memory
71 executable. Doing this is a really bad idea. Probably indicates a
72 badly coded executable, but could indicate an attack. This executable
73 should be reported in bugzilla, you must turn on the allow_execheap
74 boolean. Disabled by default.
75 setsebool -P allow_execheap 1
77 If you want to allow unconfined executables to map a memory region as
81 both executable and writable, this is dangerous and the executable
82 should be reported in bugzilla), you must turn on the allow_execmem
83 boolean. Enabled by default.
84 setsebool -P allow_execmem 1
86 If you want to allow all unconfined executables to use libraries
90 requiring text relocation that are not labeled textrel_shlib_t), you
91 must turn on the allow_execmod boolean. Enabled by default.
92 setsebool -P allow_execmod 1
94 If you want to allow unconfined executables to make their stack exe‐
98 cutable. This should never, ever be necessary. Probably indicates a
99 badly coded executable, but could indicate an attack. This executable
100 should be reported in bugzilla), you must turn on the allow_execstack
101 boolean. Enabled by default.
102 setsebool -P allow_execstack 1
104 If you want to allow sysadm to debug or ptrace all processes, you must
108 turn on the allow_ptrace boolean. Disabled by default.
109 setsebool -P allow_ptrace 1
111 If you want to allow all domains to have the kernel load modules, you
115 must turn on the domain_kernel_load_modules boolean. Disabled by
116 default.
117 setsebool -P domain_kernel_load_modules 1
119 If you want to allow all domains to execute in fips_mode, you must turn
123 on the fips_mode boolean. Enabled by default.
124 setsebool -P fips_mode 1
126 If you want to enable reading of urandom for all domains, you must turn
130 on the global_ssp boolean. Disabled by default.
131 setsebool -P global_ssp 1
133 If you want to allow certain domains to map low memory in the kernel,
137 you must turn on the mmap_low_allowed boolean. Disabled by default.
138 setsebool -P mmap_low_allowed 1
140 If you want to boolean to determine whether the system permits loading
144 policy, setting enforcing mode, and changing boolean values. Set this
145 to true and you have to reboot to set it back, you must turn on the
146 secure_mode_policyload boolean. Disabled by default.
147 setsebool -P secure_mode_policyload 1
149 If you want to support X userspace object manager, you must turn on the
153 xserver_object_manager boolean. Disabled by default.
154 setsebool -P xserver_object_manager 1

160 The SELinux process type nagios_eventhandler_plugin_t can manage files
161 labeled with the following file types. The paths listed are the
162 default paths for these file types. Note the processes UID still need
163 to have DAC permissions.
164 file_type
166 all files on the system
168
171 SELinux requires files to have an extended attribute to define the file
172 type.
173 You can see the context of a file using the -Z option to ls
175 Policy governs the access confined processes have to these files.
177 SELinux nagios_eventhandler_plugin policy is very flexible allowing
178 users to setup their nagios_eventhandler_plugin processes in as secure
179 a method as possible.
180 STANDARD FILE CONTEXT
182 SELinux defines the file context types for the nagios_even‐
184 thandler_plugin, if you wanted to store files with these types in a
185 diffent paths, you need to execute the semanage command to sepecify
186 alternate labeling and then use restorecon to put the labels on disk.
187 semanage fcontext -a -t nagios_eventhandler_plugin_tmp_t '/srv/myna‐
189 gios_eventhandler_plugin_content(/.*)?'
190 restorecon -R -v /srv/mynagios_eventhandler_plugin_content
191 Note: SELinux often uses regular expressions to specify labels that
193 match multiple files.
194 The following file types are defined for nagios_eventhandler_plugin:
196 nagios_eventhandler_plugin_exec_t
200 - Set files with the nagios_eventhandler_plugin_exec_t type, if you
202 want to transition an executable to the nagios_eventhandler_plugin_t
203 domain.
204 nagios_eventhandler_plugin_tmp_t
208 - Set files with the nagios_eventhandler_plugin_tmp_t type, if you want
210 to store nagios eventhandler plugin temporary files in the /tmp direc‐
211 tories.
212 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
