6 amtu_selinux - Security Enhanced Linux Policy for the amtu processes
7
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
19
20
21
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
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
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 domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 The SELinux process type amtu_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.
67
68 boot_t
69
70 /efi(/.*)?
71 /boot/.*
72 /vmlinuz.*
73 /initrd.img.*
74 /boot
75
76
78 SELinux requires files to have an extended attribute to define the file
79 type.
80
81 You can see the context of a file using the -Z option to ls
82
83 Policy governs the access confined processes have to these files.
84 SELinux amtu policy is very flexible allowing users to setup their amtu
85 processes in as secure a method as possible.
86
87 The following file types are defined for amtu:
88
89
90
91 amtu_exec_t
92
93 - Set files with the amtu_exec_t type, if you want to transition an
94 executable to the amtu_t domain.
95
96
97 Paths:
98 /usr/bin/amtu, /usr/sbin/amtu
99
100
101 amtu_initrc_exec_t
102
103 - Set files with the amtu_initrc_exec_t type, if you want to transition
104 an executable to the amtu_initrc_t domain.
105
106
107
108 Note: File context can be temporarily modified with the chcon command.
109 If you want to permanently change the file context you need to use the
110 semanage fcontext command. This will modify the SELinux labeling data‐
111 base. You will need to use restorecon to apply the labels.
112
113
115 semanage fcontext can also be used to manipulate default file context
116 mappings.
117
118 semanage permissive can also be used to manipulate whether or not a
119 process type is permissive.
120
121 semanage module can also be used to enable/disable/install/remove pol‐
122 icy modules.
123
124 semanage boolean can also be used to manipulate the booleans
125
126
127 system-config-selinux is a GUI tool available to customize SELinux pol‐
128 icy settings.
