NAME

6       netutils_selinux - Security Enhanced Linux Policy for the netutils pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  netutils  processes  via  flexible
11       mandatory access control.
12
13       The  netutils  processes  execute with the netutils_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep netutils_t
20
21
22

ENTRYPOINTS

24       The netutils_t SELinux type can be entered via the netutils_exec_t file
25       type.
26
27       The default entrypoint paths for the netutils_t domain are the  follow‐
28       ing:
29
30       /sbin/arping, /usr/sbin/arping, /usr/sbin/tcpdump
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       netutils policy is very flexible allowing users to setup their netutils
40       processes in as secure a method as possible.
41
42       The following process types are defined for netutils:
43
44       netutils_t
45
46       Note: semanage permissive -a netutils_t can be used to make the process
47       type  netutils_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  netu‐
54       tils policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run netutils with the tightest access
56       possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to deny all system processes and Linux users to  use  blue‐
69       tooth wireless technology, you must turn on the deny_bluetooth boolean.
70       Enabled by default.
71
72       setsebool -P deny_bluetooth 1
73
74
75
76       If you want to allow all domains to execute in fips_mode, you must turn
77       on the fips_mode boolean. Enabled by default.
78
79       setsebool -P fips_mode 1
80
81
82
83       If  you  want  to allow confined applications to run with kerberos, you
84       must turn on the kerberos_enabled boolean. Enabled by default.
85
86       setsebool -P kerberos_enabled 1
87
88
89
90       If you want to allow system to run with  NIS,  you  must  turn  on  the
91       nis_enabled boolean. Disabled by default.
92
93       setsebool -P nis_enabled 1
94
95
96
97       If  you  want to allow confined applications to use nscd shared memory,
98       you must turn on the nscd_use_shm boolean. Disabled by default.
99
100       setsebool -P nscd_use_shm 1

103

MANAGED FILES

105       The SELinux process type netutils_t can manage files labeled  with  the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       netutils_tmp_t
110
111
112

FILE CONTEXTS

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 netutils policy is very flexible allowing users to setup  their
121       netutils processes in as secure a method as possible.
122
123       STANDARD FILE CONTEXT
124
125       SELinux  defines the file context types for the netutils, if you wanted
126       to store files with these types in a diffent paths, you need to execute
127       the  semanage  command  to  sepecify  alternate  labeling  and then use
128       restorecon to put the labels on disk.
129
130       semanage fcontext -a -t netutils_tmp_t '/srv/mynetutils_content(/.*)?'
131       restorecon -R -v /srv/mynetutils_content
132
133       Note: SELinux often uses regular expressions  to  specify  labels  that
134       match multiple files.
135
136       The following file types are defined for netutils:
137
138
139
140       netutils_exec_t
141
142       - Set files with the netutils_exec_t type, if you want to transition an
143       executable to the netutils_t domain.
144
145
146       Paths:
147            /sbin/arping, /usr/sbin/arping, /usr/sbin/tcpdump
148
149
150       netutils_tmp_t
151
152       - Set files with the netutils_tmp_t type, if you want to store netutils
153       temporary files in the /tmp directories.
154
155
156
157       Note:  File context can be temporarily modified with the chcon command.
158       If you want to permanently change the file context you need to use  the
159       semanage fcontext command.  This will modify the SELinux labeling data‐
160       base.  You will need to use restorecon to apply the labels.
161
162

COMMANDS

164       semanage fcontext can also be used to manipulate default  file  context
165       mappings.
166
167       semanage  permissive  can  also  be used to manipulate whether or not a
168       process type is permissive.
169
170       semanage module can also be used to enable/disable/install/remove  pol‐
171       icy modules.
172
173       semanage boolean can also be used to manipulate the booleans
174
175
176       system-config-selinux is a GUI tool available to customize SELinux pol‐
177       icy settings.
