6 sandbox_min_client_selinux - Security Enhanced Linux Policy for the
7 sandbox_min_client processes
8
10 Security-Enhanced Linux secures the sandbox_min_client processes via
11 flexible mandatory access control.
12
13 The sandbox_min_client processes execute with the sandbox_min_client_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sandbox_min_client_t
20
21
22
24 SELinux defines process types (domains) for each process running on the
25 system
26
27 You can see the context of a process using the -Z option to ps
28
29 Policy governs the access confined processes have to files. SELinux
30 sandbox_min_client policy is very flexible allowing users to setup
31 their sandbox_min_client processes in as secure a method as possible.
32
33 The following process types are defined for sandbox_min_client:
34
35 sandbox_min_client_t
36
37 Note: semanage permissive -a sandbox_min_client_t can be used to make
38 the process type sandbox_min_client_t permissive. SELinux does not deny
39 access to permissive process types, but the AVC (SELinux denials) mes‐
40 sages are still generated.
41
42
44 SELinux policy is customizable based on least access required. sand‐
45 box_min_client policy is extremely flexible and has several booleans
46 that allow you to manipulate the policy and run sandbox_min_client with
47 the tightest access possible.

51 If you want to deny user domains applications to map a memory region as
52 both executable and writable, this is dangerous and the executable
53 should be reported in bugzilla, you must turn on the deny_execmem bool‐
54 ean. Enabled by default.

61 The SELinux process type sandbox_min_client_t can manage files labeled
62 with the following file types. The paths listed are the default paths
63 for these file types. Note the processes UID still need to have DAC
64 permissions.

82 semanage fcontext can also be used to manipulate default file context
83 mappings.
84
85 semanage permissive can also be used to manipulate whether or not a
86 process type is permissive.
87
88 semanage module can also be used to enable/disable/install/remove pol‐
89 icy modules.
90
91 semanage boolean can also be used to manipulate the booleans
92

94 system-config-selinux is a GUI tool available to customize SELinux pol‐
95 icy settings.
