6 nagios_mail_plugin_selinux - Security Enhanced Linux Policy for the na‐
7 gios_mail_plugin processes
8
10 Security-Enhanced Linux secures the nagios_mail_plugin processes via
11 flexible mandatory access control.
12 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 For example:
18 ps -eZ | grep nagios_mail_plugin_t
20
24 The nagios_mail_plugin_t SELinux type can be entered via the na‐
25 gios_mail_plugin_exec_t file type.
26 The default entrypoint paths for the nagios_mail_plugin_t domain are
28 the following:
29 /usr/lib/nagios/plugins/check_mailq
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for nagios_mail_plugin:
43 nagios_mail_plugin_t
45 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
53 SELinux policy is customizable based on least access required. na‐
54 gios_mail_plugin policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run nagios_mail_plugin with
56 the tightest access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow confined applications to use nscd shared memory,
68 you must turn on the nscd_use_shm boolean. Enabled by default.
69 setsebool -P nscd_use_shm 1
71
75 SELinux requires files to have an extended attribute to define the file
76 type.
77 You can see the context of a file using the -Z option to ls
79 Policy governs the access confined processes have to these files.
81 SELinux nagios_mail_plugin policy is very flexible allowing users to
82 setup their nagios_mail_plugin processes in as secure a method as pos‐
83 sible.
84 The following file types are defined for nagios_mail_plugin:
86 nagios_mail_plugin_exec_t
90 - Set files with the nagios_mail_plugin_exec_t type, if you want to
92 transition an executable to the nagios_mail_plugin_t domain.
93 Note: File context can be temporarily modified with the chcon command.
97 If you want to permanently change the file context you need to use the
98 semanage fcontext command. This will modify the SELinux labeling data‐
99 base. You will need to use restorecon to apply the labels.
100
103 semanage fcontext can also be used to manipulate default file context
104 mappings.
105 semanage permissive can also be used to manipulate whether or not a
107 process type is permissive.
108 semanage module can also be used to enable/disable/install/remove pol‐
110 icy modules.
111 semanage boolean can also be used to manipulate the booleans
113 system-config-selinux is a GUI tool available to customize SELinux pol‐
116 icy settings.
