6 sandbox_x_client_selinux - Security Enhanced Linux Policy for the sand‐
7 box_x_client processes
8
10 Security-Enhanced Linux secures the sandbox_x_client processes via
11 flexible mandatory access control.
12
13 The sandbox_x_client processes execute with the sandbox_x_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_x_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_x_client policy is very flexible allowing users to setup their
31 sandbox_x_client processes in as secure a method as possible.
32
33 The following process types are defined for sandbox_x_client:
34
35 sandbox_x_client_t
36
37 Note: semanage permissive -a sandbox_x_client_t can be used to make the
38 process type sandbox_x_client_t permissive. SELinux does not deny ac‐
39 cess 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_x_client policy is extremely flexible and has several booleans that
46 allow you to manipulate the policy and run sandbox_x_client with the
47 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_x_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.
