6 nagios_admin_plugin_selinux - Security Enhanced Linux Policy for the
7 nagios_admin_plugin processes
8
10 Security-Enhanced Linux secures the nagios_admin_plugin processes via
11 flexible mandatory access control.
12
13 The nagios_admin_plugin processes execute with the nagios_admin_plug‐
14 in_t SELinux type. You can check if you have these processes running by
15 executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep nagios_admin_plugin_t
20
21
22
24 The nagios_admin_plugin_t SELinux type can be entered via the
25 nagios_admin_plugin_exec_t file type.
26
27 The default entrypoint paths for the nagios_admin_plugin_t domain are
28 the following:
29
30 /usr/lib/nagios/plugins/check_file_age
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 nagios_admin_plugin policy is very flexible allowing users to setup
40 their nagios_admin_plugin processes in as secure a method as possible.
41
42 The following process types are defined for nagios_admin_plugin:
43
44 nagios_admin_plugin_t
45
46 Note: semanage permissive -a nagios_admin_plugin_t can be used to make
47 the process type nagios_admin_plugin_t permissive. SELinux does not
48 deny access to permissive process types, but the AVC (SELinux denials)
49 messages are still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 nagios_admin_plugin policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run nagios_admin_plug‐
56 in with the tightest access possible.
57
58
59
60 If you want to deny any process from ptracing or debugging any other
61 processes, you must turn on the deny_ptrace boolean. Enabled by
62 default.
63
64 setsebool -P deny_ptrace 1
65
66
67
68 If you want to allow any process to mmap any file on system with
69 attribute file_type, you must turn on the domain_can_mmap_files bool‐
70 ean. Enabled by default.
71
72 setsebool -P domain_can_mmap_files 1
73
74
75
76 If you want to allow all domains write to kmsg_device, while kernel is
77 executed with systemd.log_target=kmsg parameter, you must turn on the
78 domain_can_write_kmsg boolean. Disabled by default.
79
80 setsebool -P domain_can_write_kmsg 1
81
82
83
84 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the domain_fd_use boolean. Enabled by default.
86
87 setsebool -P domain_fd_use 1
88
89
90
91 If you want to allow all domains to have the kernel load modules, you
92 must turn on the domain_kernel_load_modules boolean. Disabled by
93 default.
94
95 setsebool -P domain_kernel_load_modules 1
96
97
98
99 If you want to allow all domains to execute in fips_mode, you must turn
100 on the fips_mode boolean. Enabled by default.
101
102 setsebool -P fips_mode 1
103
104
105
106 If you want to enable reading of urandom for all domains, you must turn
107 on the global_ssp boolean. Disabled by default.
108
109 setsebool -P global_ssp 1
110
111
112
114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux nagios_admin_plugin policy is very flexible allowing users to
121 setup their nagios_admin_plugin processes in as secure a method as pos‐
122 sible.
123
124 The following file types are defined for nagios_admin_plugin:
125
126
127
128 nagios_admin_plugin_exec_t
129
130 - Set files with the nagios_admin_plugin_exec_t type, if you want to
131 transition an executable to the nagios_admin_plugin_t domain.
132
133
134
135 Note: File context can be temporarily modified with the chcon command.
136 If you want to permanently change the file context you need to use the
137 semanage fcontext command. This will modify the SELinux labeling data‐
138 base. You will need to use restorecon to apply the labels.
139
140
142 semanage fcontext can also be used to manipulate default file context
143 mappings.
144
145 semanage permissive can also be used to manipulate whether or not a
146 process type is permissive.
147
148 semanage module can also be used to enable/disable/install/remove pol‐
149 icy modules.
150
151 semanage boolean can also be used to manipulate the booleans
152
153
154 system-config-selinux is a GUI tool available to customize SELinux pol‐
155 icy settings.
