6 nagios_mail_plugin_selinux - Security Enhanced Linux Policy for the
7 nagios_mail_plugin processes
8
10 Security-Enhanced Linux secures the nagios_mail_plugin processes via
11 flexible mandatory access control.
12
13 The nagios_mail_plugin processes execute with the nagios_mail_plugin_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
17 For example:
18
19 ps -eZ | grep nagios_mail_plugin_t
20
21
22
24 The nagios_mail_plugin_t SELinux type can be entered via the
25 nagios_mail_plugin_exec_t file type.
26
27 The default entrypoint paths for the nagios_mail_plugin_t domain are
28 the following:
29
30 /usr/lib/nagios/plugins/check_mailq
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_mail_plugin policy is very flexible allowing users to setup
40 their nagios_mail_plugin processes in as secure a method as possible.
41
42 The following process types are defined for nagios_mail_plugin:
43
44 nagios_mail_plugin_t
45
46 Note: semanage permissive -a nagios_mail_plugin_t can be used to make
47 the process type nagios_mail_plugin_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 nagios_mail_plugin policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run nagios_mail_plugin
56 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
113 If you want to allow confined applications to use nscd shared memory,
114 you must turn on the nscd_use_shm boolean. Disabled by default.
115
116 setsebool -P nscd_use_shm 1
117
118
119
121 SELinux requires files to have an extended attribute to define the file
122 type.
123
124 You can see the context of a file using the -Z option to ls
125
126 Policy governs the access confined processes have to these files.
127 SELinux nagios_mail_plugin policy is very flexible allowing users to
128 setup their nagios_mail_plugin processes in as secure a method as pos‐
129 sible.
130
131 The following file types are defined for nagios_mail_plugin:
132
133
134
135 nagios_mail_plugin_exec_t
136
137 - Set files with the nagios_mail_plugin_exec_t type, if you want to
138 transition an executable to the nagios_mail_plugin_t domain.
139
140
141
142 Note: File context can be temporarily modified with the chcon command.
143 If you want to permanently change the file context you need to use the
144 semanage fcontext command. This will modify the SELinux labeling data‐
145 base. You will need to use restorecon to apply the labels.
146
147
149 semanage fcontext can also be used to manipulate default file context
150 mappings.
151
152 semanage permissive can also be used to manipulate whether or not a
153 process type is permissive.
154
155 semanage module can also be used to enable/disable/install/remove pol‐
156 icy modules.
157
158 semanage boolean can also be used to manipulate the booleans
159
160
161 system-config-selinux is a GUI tool available to customize SELinux pol‐
162 icy settings.
