6 NetworkManager_dispatcher_custom_selinux - Security Enhanced Linux Pol‐
7 icy for the NetworkManager_dispatcher_custom processes
8
10 Security-Enhanced Linux secures the NetworkManager_dispatcher_custom
11 processes via flexible mandatory access control.
12
13 The NetworkManager_dispatcher_custom processes execute with the Net‐
14 workManager_dispatcher_custom_t SELinux type. You can check if you have
15 these processes running by executing the ps command with the -Z quali‐
16 fier.
17
18 For example:
19
20 ps -eZ | grep NetworkManager_dispatcher_custom_t
21
22
23
25 The NetworkManager_dispatcher_custom_t SELinux type can be entered via
26 the NetworkManager_dispatcher_script_t file type.
27
28 The default entrypoint paths for the NetworkManager_dispatcher_custom_t
29 domain are the following:
30
31 /etc/NetworkManager/dispatcher.d(/.*)?, /usr/lib/NetworkManager/dis‐
32 patcher.d(/.*)?
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 NetworkManager_dispatcher_custom policy is very flexible allowing users
42 to setup their NetworkManager_dispatcher_custom processes in as secure
43 a method as possible.
44
45 The following process types are defined for NetworkManager_dis‐
46 patcher_custom:
47
48 NetworkManager_dispatcher_custom_t
49
50 Note: semanage permissive -a NetworkManager_dispatcher_custom_t can be
51 used to make the process type NetworkManager_dispatcher_custom_t per‐
52 missive. SELinux does not deny access to permissive process types, but
53 the AVC (SELinux denials) messages are still generated.
54
55
57 SELinux policy is customizable based on least access required. Net‐
58 workManager_dispatcher_custom policy is extremely flexible and has sev‐
59 eral booleans that allow you to manipulate the policy and run Network‐
60 Manager_dispatcher_custom with the tightest access possible.
61
62
63
64 If you want to deny user domains applications to map a memory region as
65 both executable and writable, this is dangerous and the executable
66 should be reported in bugzilla, you must turn on the deny_execmem bool‐
67 ean. Disabled by default.
68
69 setsebool -P deny_execmem 1
70
71
72
73 If you want to control the ability to mmap a low area of the address
74 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
75 the mmap_low_allowed boolean. Disabled by default.
76
77 setsebool -P mmap_low_allowed 1
78
79
80
81 If you want to disable kernel module loading, you must turn on the se‐
82 cure_mode_insmod boolean. Disabled by default.
83
84 setsebool -P secure_mode_insmod 1
85
86
87
88 If you want to allow unconfined executables to make their heap memory
89 executable. Doing this is a really bad idea. Probably indicates a
90 badly coded executable, but could indicate an attack. This executable
91 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
92 echeap boolean. Disabled by default.
93
94 setsebool -P selinuxuser_execheap 1
95
96
97
98 If you want to allow unconfined executables to make their stack exe‐
99 cutable. This should never, ever be necessary. Probably indicates a
100 badly coded executable, but could indicate an attack. This executable
101 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
102 stack boolean. Enabled by default.
103
104 setsebool -P selinuxuser_execstack 1

107
109 The SELinux process type NetworkManager_dispatcher_custom_t can manage
110 files labeled with the following file types. The paths listed are the
111 default paths for these file types. Note the processes UID still need
112 to have DAC permissions.
113
114 file_type
115
116 all files on the system
117
118
120 semanage fcontext can also be used to manipulate default file context
121 mappings.
122
123 semanage permissive can also be used to manipulate whether or not a
124 process type is permissive.
125
126 semanage module can also be used to enable/disable/install/remove pol‐
127 icy modules.
128
129 semanage boolean can also be used to manipulate the booleans
130
131
132 system-config-selinux is a GUI tool available to customize SELinux pol‐
133 icy settings.
