6 nagios_unconfined_plugin_selinux - Security Enhanced Linux Policy for
7 the nagios_unconfined_plugin processes
8
10 Security-Enhanced Linux secures the nagios_unconfined_plugin processes
11 via flexible mandatory access control.
12
13 The nagios_unconfined_plugin processes execute with the nagios_uncon‐
14 fined_plugin_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep nagios_unconfined_plugin_t
20
21
22
24 The nagios_unconfined_plugin_t SELinux type can be entered via the
25 file_type, nagios_unconfined_plugin_exec_t, unlabeled_t, proc_type,
26 filesystem_type, mtrr_device_t, sysctl_type file types.
27
28 The default entrypoint paths for the nagios_unconfined_plugin_t domain
29 are the following:
30
31 all files on the system, /usr/lib(64)?/nagios/plugins/.*, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 nagios_unconfined_plugin policy is very flexible allowing users to set‐
41 up their nagios_unconfined_plugin processes in as secure a method as
42 possible.
43
44 The following process types are defined for nagios_unconfined_plugin:
45
46 nagios_unconfined_plugin_t
47
48 Note: semanage permissive -a nagios_unconfined_plugin_t can be used to
49 make the process type nagios_unconfined_plugin_t permissive. SELinux
50 does not deny access to permissive process types, but the AVC (SELinux
51 denials) messages are still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 nagios_unconfined_plugin policy is extremely flexible and has several
57 booleans that allow you to manipulate the policy and run nagios_uncon‐
58 fined_plugin with the tightest access possible.
59
60
61
62 If you want to allow all domains to use other domains file descriptors,
63 you must turn on the allow_domain_fd_use boolean. Enabled by default.
64
65 setsebool -P allow_domain_fd_use 1
66
67
68
69 If you want to allow unconfined executables to make their heap memory
70 executable. Doing this is a really bad idea. Probably indicates a
71 badly coded executable, but could indicate an attack. This executable
72 should be reported in bugzilla, you must turn on the allow_execheap
73 boolean. Disabled by default.
74
75 setsebool -P allow_execheap 1
76
77
78
79 If you want to allow unconfined executables to map a memory region as
80 both executable and writable, this is dangerous and the executable
81 should be reported in bugzilla), you must turn on the allow_execmem
82 boolean. Enabled by default.
83
84 setsebool -P allow_execmem 1
85
86
87
88 If you want to allow all unconfined executables to use libraries
89 requiring text relocation that are not labeled textrel_shlib_t), you
90 must turn on the allow_execmod boolean. Enabled by default.
91
92 setsebool -P allow_execmod 1
93
94
95
96 If you want to allow unconfined executables to make their stack exe‐
97 cutable. This should never, ever be necessary. Probably indicates a
98 badly coded executable, but could indicate an attack. This executable
99 should be reported in bugzilla), you must turn on the allow_execstack
100 boolean. Enabled by default.
101
102 setsebool -P allow_execstack 1
103
104
105
106 If you want to allow sysadm to debug or ptrace all processes, you must
107 turn on the allow_ptrace boolean. Disabled by default.
108
109 setsebool -P allow_ptrace 1
110
111
112
113 If you want to allow all domains to have the kernel load modules, you
114 must turn on the domain_kernel_load_modules boolean. Disabled by
115 default.
116
117 setsebool -P domain_kernel_load_modules 1
118
119
120
121 If you want to allow all domains to execute in fips_mode, you must turn
122 on the fips_mode boolean. Enabled by default.
123
124 setsebool -P fips_mode 1
125
126
127
128 If you want to enable reading of urandom for all domains, you must turn
129 on the global_ssp boolean. Disabled by default.
130
131 setsebool -P global_ssp 1
132
133
134
135 If you want to allow certain domains to map low memory in the kernel,
136 you must turn on the mmap_low_allowed boolean. Disabled by default.
137
138 setsebool -P mmap_low_allowed 1
139
140
141
142 If you want to boolean to determine whether the system permits loading
143 policy, setting enforcing mode, and changing boolean values. Set this
144 to true and you have to reboot to set it back, you must turn on the
145 secure_mode_policyload boolean. Disabled by default.
146
147 setsebool -P secure_mode_policyload 1
148
149
150
151 If you want to support X userspace object manager, you must turn on the
152 xserver_object_manager boolean. Disabled by default.
153
154 setsebool -P xserver_object_manager 1
155
156
157
159 The SELinux process type nagios_unconfined_plugin_t can manage files
160 labeled with the following file types. The paths listed are the
161 default paths for these file types. Note the processes UID still need
162 to have DAC permissions.
163
164 file_type
165
166 all files on the system
167
168
170 SELinux requires files to have an extended attribute to define the file
171 type.
172
173 You can see the context of a file using the -Z option to ls
174
175 Policy governs the access confined processes have to these files.
176 SELinux nagios_unconfined_plugin policy is very flexible allowing users
177 to setup their nagios_unconfined_plugin processes in as secure a method
178 as possible.
179
180 The following file types are defined for nagios_unconfined_plugin:
181
182
183
184 nagios_unconfined_plugin_exec_t
185
186 - Set files with the nagios_unconfined_plugin_exec_t type, if you want
187 to transition an executable to the nagios_unconfined_plugin_t domain.
188
189
190
191 Note: File context can be temporarily modified with the chcon command.
192 If you want to permanently change the file context you need to use the
193 semanage fcontext command. This will modify the SELinux labeling data‐
194 base. You will need to use restorecon to apply the labels.
195
196
198 semanage fcontext can also be used to manipulate default file context
199 mappings.
200
201 semanage permissive can also be used to manipulate whether or not a
202 process type is permissive.
203
204 semanage module can also be used to enable/disable/install/remove pol‐
205 icy modules.
206
207 semanage boolean can also be used to manipulate the booleans
208
209
210 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
