NAME

6       amtu_selinux - Security Enhanced Linux Policy for the amtu processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the amtu processes via flexible manda‐
10       tory access control.
11
12       The amtu processes execute with the amtu_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep amtu_t

21

ENTRYPOINTS

23       The amtu_t SELinux type can be entered via the amtu_exec_t file type.
24
25       The default entrypoint paths for the amtu_t domain are the following:
26
27       /usr/bin/amtu, /usr/sbin/amtu
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       amtu policy is very flexible allowing users to setup  their  amtu  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for amtu:
40
41       amtu_t
42
43       Note:  semanage  permissive  -a  amtu_t can be used to make the process
44       type amtu_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   amtu
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run amtu with the tightest access possible.
53
54
55
56       If you want to allow all daemons the ability to  read/write  terminals,
57       you must turn on the daemons_use_tty boolean. Disabled by default.
58
59       setsebool -P daemons_use_tty 1
60
61
62
63       If  you  want  to deny any process from ptracing or debugging any other
64       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
65       default.
66
67       setsebool -P deny_ptrace 1
68
69
70
71       If  you  want  to  allow  any  process  to mmap any file on system with
72       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
73       ean. Enabled by default.
74
75       setsebool -P domain_can_mmap_files 1
76
77
78
79       If  you want to allow all domains write to kmsg_device, while kernel is
80       executed with systemd.log_target=kmsg parameter, you must turn  on  the
81       domain_can_write_kmsg boolean. Disabled by default.
82
83       setsebool -P domain_can_write_kmsg 1
84
85
86
87       If you want to allow all domains to use other domains file descriptors,
88       you must turn on the domain_fd_use boolean. Enabled by default.
89
90       setsebool -P domain_fd_use 1
91
92
93
94       If you want to allow all domains to have the kernel load  modules,  you
95       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
96       default.
97
98       setsebool -P domain_kernel_load_modules 1
99
100
101
102       If you want to allow all domains to execute in fips_mode, you must turn
103       on the fips_mode boolean. Enabled by default.
104
105       setsebool -P fips_mode 1
106
107
108
109       If you want to enable reading of urandom for all domains, you must turn
110       on the global_ssp boolean. Disabled by default.
111
112       setsebool -P global_ssp 1
113
114
115

MANAGED FILES

117       The SELinux process type amtu_t can manage files labeled with the  fol‐
118       lowing  file  types.   The paths listed are the default paths for these
119       file types.  Note the processes UID still need to have DAC permissions.
120
121       boot_t
122
123            /boot/.*
124            /vmlinuz.*
125            /initrd.img.*
126            /boot
127
128

FILE CONTEXTS

130       SELinux requires files to have an extended attribute to define the file
131       type.
132
133       You can see the context of a file using the -Z option to ls
134
135       Policy  governs  the  access  confined  processes  have to these files.
136       SELinux amtu policy is very flexible allowing users to setup their amtu
137       processes in as secure a method as possible.
138
139       The following file types are defined for amtu:
140
141
142
143       amtu_exec_t
144
145       -  Set  files  with  the amtu_exec_t type, if you want to transition an
146       executable to the amtu_t domain.
147
148
149       Paths:
150            /usr/bin/amtu, /usr/sbin/amtu
151
152
153       amtu_initrc_exec_t
154
155       - Set files with the amtu_initrc_exec_t type, if you want to transition
156       an executable to the amtu_initrc_t domain.
157
158
159
160       Note:  File context can be temporarily modified with the chcon command.
161       If you want to permanently change the file context you need to use  the
162       semanage fcontext command.  This will modify the SELinux labeling data‐
163       base.  You will need to use restorecon to apply the labels.
164
165

COMMANDS

167       semanage fcontext can also be used to manipulate default  file  context
168       mappings.
169
170       semanage  permissive  can  also  be used to manipulate whether or not a
171       process type is permissive.
172
173       semanage module can also be used to enable/disable/install/remove  pol‐
174       icy modules.
175
176       semanage boolean can also be used to manipulate the booleans
177
178
179       system-config-selinux is a GUI tool available to customize SELinux pol‐
180       icy settings.
