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       /bin/arping,     /sbin/arping,    /usr/bin/arping,    /usr/sbin/arping,
31       /usr/sbin/tcpdump
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       netutils policy is very flexible allowing users to setup their netutils
41       processes in as secure a method as possible.
42
43       The following process types are defined for netutils:
44
45       netutils_t
46
47       Note: semanage permissive -a netutils_t can be used to make the process
48       type netutils_t permissive. SELinux does not deny access to  permissive
49       process  types, but the AVC (SELinux denials) messages are still gener‐
50       ated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least access  required.   netu‐
55       tils  policy  is extremely flexible and has several booleans that allow
56       you to manipulate the policy and run netutils with the tightest  access
57       possible.
58
59
60
61       If  you  want to deny all system processes and Linux users to use blue‐
62       tooth wireless technology, you must turn on the deny_bluetooth boolean.
63       Enabled by default.
64
65       setsebool -P deny_bluetooth 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73

75

MANAGED FILES

77       The SELinux process type netutils_t can manage files labeled  with  the
78       following file types.  The paths listed are the default paths for these
79       file types.  Note the processes UID still need to have DAC permissions.
80
81       krb5_host_rcache_t
82
83            /var/tmp/krb5_0.rcache2
84            /var/cache/krb5rcache(/.*)?
85            /var/tmp/nfs_0
86            /var/tmp/DNS_25
87            /var/tmp/host_0
88            /var/tmp/imap_0
89            /var/tmp/HTTP_23
90            /var/tmp/HTTP_48
91            /var/tmp/ldap_55
92            /var/tmp/ldap_487
93            /var/tmp/ldapmap1_0
94
95       netutils_tmp_t

FILE CONTEXTS

100       SELinux requires files to have an extended attribute to define the file
101       type.
102
103       You can see the context of a file using the -Z option to ls
104
105       Policy  governs  the  access  confined  processes  have to these files.
106       SELinux netutils policy is very flexible allowing users to setup  their
107       netutils processes in as secure a method as possible.
108
109       STANDARD FILE CONTEXT
110
111       SELinux  defines the file context types for the netutils, if you wanted
112       to store files with these types in a diffent paths, you need to execute
113       the  semanage  command  to  specify alternate labeling and then use re‐
114       storecon to put the labels on disk.
115
116       semanage fcontext -a -t netutils_tmp_t '/srv/mynetutils_content(/.*)?'
117       restorecon -R -v /srv/mynetutils_content
118
119       Note: SELinux often uses regular expressions  to  specify  labels  that
120       match multiple files.
121
122       The following file types are defined for netutils:
123
124
125
126       netutils_exec_t
127
128       - Set files with the netutils_exec_t type, if you want to transition an
129       executable to the netutils_t domain.
130
131
132       Paths:
133            /bin/arping,  /sbin/arping,   /usr/bin/arping,   /usr/sbin/arping,
134            /usr/sbin/tcpdump
135
136
137       netutils_tmp_t
138
139       - Set files with the netutils_tmp_t type, if you want to store netutils
140       temporary files in the /tmp directories.
141
142
143
144       Note: File context can be temporarily modified with the chcon  command.
145       If  you want to permanently change the file context you need to use the
146       semanage fcontext command.  This will modify the SELinux labeling data‐
147       base.  You will need to use restorecon to apply the labels.
148
149

COMMANDS

151       semanage  fcontext  can also be used to manipulate default file context
152       mappings.
153
154       semanage permissive can also be used to manipulate  whether  or  not  a
155       process type is permissive.
156
157       semanage  module can also be used to enable/disable/install/remove pol‐
158       icy modules.
159
160       semanage boolean can also be used to manipulate the booleans
161
162
163       system-config-selinux is a GUI tool available to customize SELinux pol‐
164       icy settings.
