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 The sandbox_x_client_t SELinux type can be entered via the sand‐
25 box_exec_t file type.
26
27 The default entrypoint paths for the sandbox_x_client_t domain are the
28 following:
29
30 /usr/share/sandbox/start
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sandbox_x_client policy is very flexible allowing users to setup their
40 sandbox_x_client processes in as secure a method as possible.
41
42 The following process types are defined for sandbox_x_client:
43
44 sandbox_x_client_t
45
46 Note: semanage permissive -a sandbox_x_client_t can be used to make the
47 process type sandbox_x_client_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. sand‐
54 box_x_client policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sandbox_x_client with the
56 tightest access possible.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.
72
73 setsebool -P deny_execmem 1
74
75
76
77 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79
80 setsebool -P fips_mode 1
81
82
83
84 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86
87 setsebool -P kerberos_enabled 1
88
89
90
91 If you want to allow system to run with NIS, you must turn on the
92 nis_enabled boolean. Disabled by default.
93
94 setsebool -P nis_enabled 1
95
96
97
98 If you want to allow confined applications to use nscd shared memory,
99 you must turn on the nscd_use_shm boolean. Disabled by default.
100
101 setsebool -P nscd_use_shm 1
102
103
104
106 The SELinux process type sandbox_x_client_t can manage files labeled
107 with the following file types. The paths listed are the default paths
108 for these file types. Note the processes UID still need to have DAC
109 permissions.

150 semanage fcontext can also be used to manipulate default file context
151 mappings.
152
153 semanage permissive can also be used to manipulate whether or not a
154 process type is permissive.
155
156 semanage module can also be used to enable/disable/install/remove pol‐
157 icy modules.
158
159 semanage boolean can also be used to manipulate the booleans
160
161
162 system-config-selinux is a GUI tool available to customize SELinux pol‐
163 icy settings.
