6 usbmodules_selinux - Security Enhanced Linux Policy for the usbmodules
7 processes
8
10 Security-Enhanced Linux secures the usbmodules processes via flexible
11 mandatory access control.
12
13 The usbmodules processes execute with the usbmodules_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep usbmodules_t
20
21
22
24 The usbmodules_t SELinux type can be entered via the usbmodules_exec_t
25 file type.
26
27 The default entrypoint paths for the usbmodules_t domain are the fol‐
28 lowing:
29
30 /sbin/usbmodules, /usr/sbin/usbmodules
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 usbmodules policy is very flexible allowing users to setup their usb‐
40 modules processes in as secure a method as possible.
41
42 The following process types are defined for usbmodules:
43
44 usbmodules_t
45
46 Note: semanage permissive -a usbmodules_t can be used to make the
47 process type usbmodules_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. usbmod‐
54 ules policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run usbmodules with the tightest ac‐
56 cess possible.
57
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type usbmodules_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.
71
72 usbfs_t
73
74
75
77 SELinux requires files to have an extended attribute to define the file
78 type.
79
80 You can see the context of a file using the -Z option to ls
81
82 Policy governs the access confined processes have to these files.
83 SELinux usbmodules policy is very flexible allowing users to setup
84 their usbmodules processes in as secure a method as possible.
85
86 STANDARD FILE CONTEXT
87
88 SELinux defines the file context types for the usbmodules, if you
89 wanted to store files with these types in a different paths, you need
90 to execute the semanage command to specify alternate labeling and then
91 use restorecon to put the labels on disk.
92
93 semanage fcontext -a -t usbmodules_exec_t '/srv/usbmodules/con‐
94 tent(/.*)?'
95 restorecon -R -v /srv/myusbmodules_content
96
97 Note: SELinux often uses regular expressions to specify labels that
98 match multiple files.
99
100 The following file types are defined for usbmodules:
101
102
103
104 usbmodules_exec_t
105
106 - Set files with the usbmodules_exec_t type, if you want to transition
107 an executable to the usbmodules_t domain.
108
109
110 Paths:
111 /sbin/usbmodules, /usr/sbin/usbmodules
112
113
114 Note: File context can be temporarily modified with the chcon command.
115 If you want to permanently change the file context you need to use the
116 semanage fcontext command. This will modify the SELinux labeling data‐
117 base. You will need to use restorecon to apply the labels.
118
119
121 semanage fcontext can also be used to manipulate default file context
122 mappings.
123
124 semanage permissive can also be used to manipulate whether or not a
125 process type is permissive.
126
127 semanage module can also be used to enable/disable/install/remove pol‐
128 icy modules.
129
130 semanage boolean can also be used to manipulate the booleans
131
132
133 system-config-selinux is a GUI tool available to customize SELinux pol‐
134 icy settings.
