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.
26 The default entrypoint paths for the nagios_eventhandler_plugin_t
28 domain are the following:
29 /usr/lib/icinga/plugins/eventhandlers(/.*), /usr/lib/nagios/plug‐
31 ins/eventhandlers(/.*)
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 nagios_eventhandler_plugin policy is very flexible allowing users to
41 setup their nagios_eventhandler_plugin processes in as secure a method
42 as possible.
43 The following process types are defined for nagios_eventhandler_plugin:
45 nagios_eventhandler_plugin_t
47 Note: semanage permissive -a nagios_eventhandler_plugin_t can be used
49 to make the process type nagios_eventhandler_plugin_t permissive.
50 SELinux does not deny access to permissive process types, but the AVC
51 (SELinux denials) messages are still generated.
52
55 SELinux policy is customizable based on least access required.
56 nagios_eventhandler_plugin policy is extremely flexible and has several
57 booleans that allow you to manipulate the policy and run nagios_even‐
58 thandler_plugin with the tightest access possible.
59 If you want to deny user domains applications to map a memory region as
63 both executable and writable, this is dangerous and the executable
64 should be reported in bugzilla, you must turn on the deny_execmem bool‐
65 ean. Enabled by default.
66 setsebool -P deny_execmem 1
68 If you want to allow all domains to execute in fips_mode, you must turn
72 on the fips_mode boolean. Enabled by default.
73 setsebool -P fips_mode 1
75 If you want to control the ability to mmap a low area of the address
79 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
80 the mmap_low_allowed boolean. Disabled by default.
81 setsebool -P mmap_low_allowed 1
83 If you want to disable kernel module loading, you must turn on the
87 secure_mode_insmod boolean. Enabled by default.
88 setsebool -P secure_mode_insmod 1
90 If you want to allow unconfined executables to make their heap memory
94 executable. Doing this is a really bad idea. Probably indicates a
95 badly coded executable, but could indicate an attack. This executable
96 should be reported in bugzilla, you must turn on the selin‐
97 uxuser_execheap boolean. Disabled by default.
98 setsebool -P selinuxuser_execheap 1
100 If you want to allow unconfined executables to make their stack exe‐
104 cutable. This should never, ever be necessary. Probably indicates a
105 badly coded executable, but could indicate an attack. This executable
106 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
107 stack boolean. Disabled by default.
108 setsebool -P selinuxuser_execstack 1

114 The SELinux process type nagios_eventhandler_plugin_t can manage files
115 labeled with the following file types. The paths listed are the
116 default paths for these file types. Note the processes UID still need
117 to have DAC permissions.
118 file_type
120 all files on the system
122
125 SELinux requires files to have an extended attribute to define the file
126 type.
127 You can see the context of a file using the -Z option to ls
129 Policy governs the access confined processes have to these files.
131 SELinux nagios_eventhandler_plugin policy is very flexible allowing
132 users to setup their nagios_eventhandler_plugin processes in as secure
133 a method as possible.
134 STANDARD FILE CONTEXT
136 SELinux defines the file context types for the nagios_even‐
138 thandler_plugin, if you wanted to store files with these types in a
139 diffent paths, you need to execute the semanage command to sepecify
140 alternate labeling and then use restorecon to put the labels on disk.
141 semanage fcontext -a -t nagios_eventhandler_plugin_tmp_t '/srv/myna‐
143 gios_eventhandler_plugin_content(/.*)?'
144 restorecon -R -v /srv/mynagios_eventhandler_plugin_content
145 Note: SELinux often uses regular expressions to specify labels that
147 match multiple files.
148 The following file types are defined for nagios_eventhandler_plugin:
150 nagios_eventhandler_plugin_exec_t
154 - Set files with the nagios_eventhandler_plugin_exec_t type, if you
156 want to transition an executable to the nagios_eventhandler_plugin_t
157 domain.
158 Paths:
161 /usr/lib/icinga/plugins/eventhandlers(/.*), /usr/lib/nagios/plug‐
162 ins/eventhandlers(/.*)
163 nagios_eventhandler_plugin_tmp_t
166 - Set files with the nagios_eventhandler_plugin_tmp_t type, if you want
168 to store nagios eventhandler plugin temporary files in the /tmp direc‐
169 tories.
170 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188 semanage boolean can also be used to manipulate the booleans
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
