NAME

6       nagios_mail_plugin_selinux  -  Security  Enhanced  Linux Policy for the
7       nagios_mail_plugin processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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.

51

BOOLEANS

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

FILE CONTEXTS

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

COMMANDS

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.
