6 netutils_selinux - Security Enhanced Linux Policy for the netutils pro‐
7 cesses
8
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
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 /s?bin/arping, /usr/sbin/arping, /usr/sbin/tcpdump
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 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
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 deny all system processes and Linux users to use blue‐
61 tooth wireless technology, you must turn on the deny_bluetooth boolean.
62 Enabled by default.
63
64 setsebool -P deny_bluetooth 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
76 SELinux requires files to have an extended attribute to define the file
77 type.
78
79 You can see the context of a file using the -Z option to ls
80
81 Policy governs the access confined processes have to these files.
82 SELinux netutils policy is very flexible allowing users to setup their
83 netutils processes in as secure a method as possible.
84
85 STANDARD FILE CONTEXT
86
87 SELinux defines the file context types for the netutils, if you wanted
88 to store files with these types in a diffent paths, you need to execute
89 the semanage command to sepecify alternate labeling and then use
90 restorecon to put the labels on disk.
91
92 semanage fcontext -a -t netutils_tmp_t '/srv/mynetutils_content(/.*)?'
93 restorecon -R -v /srv/mynetutils_content
94
95 Note: SELinux often uses regular expressions to specify labels that
96 match multiple files.
97
98 The following file types are defined for netutils:
99
100
101
102 netutils_exec_t
103
104 - Set files with the netutils_exec_t type, if you want to transition an
105 executable to the netutils_t domain.
106
107
108 Paths:
109 /s?bin/arping, /usr/sbin/arping, /usr/sbin/tcpdump
110
111
112 netutils_tmp_t
113
114 - Set files with the netutils_tmp_t type, if you want to store netutils
115 temporary files in the /tmp directories.
116
117
118
119 Note: File context can be temporarily modified with the chcon command.
120 If you want to permanently change the file context you need to use the
121 semanage fcontext command. This will modify the SELinux labeling data‐
122 base. You will need to use restorecon to apply the labels.
123
124
126 semanage fcontext can also be used to manipulate default file context
127 mappings.
128
129 semanage permissive can also be used to manipulate whether or not a
130 process type is permissive.
131
132 semanage module can also be used to enable/disable/install/remove pol‐
133 icy modules.
134
135 semanage boolean can also be used to manipulate the booleans
136
137
138 system-config-selinux is a GUI tool available to customize SELinux pol‐
139 icy settings.
