6 sandbox_x_selinux - Security Enhanced Linux Policy for the sandbox_x
7 processes
8
10 Security-Enhanced Linux secures the sandbox_x processes via flexible
11 mandatory access control.
12
13 The sandbox_x processes execute with the sandbox_x_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sandbox_x_t
20
21
22
24 The sandbox_x_t SELinux type can be entered via the file_type file
25 type.
26
27 The default entrypoint paths for the sandbox_x_t domain are the follow‐
28 ing:
29
30 all files on the system
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 policy is very flexible allowing users to setup their sand‐
40 box_x processes in as secure a method as possible.
41
42 The following process types are defined for sandbox_x:
43
44 sandbox_x_client_t, sandbox_xserver_t, sandbox_x_t
45
46 Note: semanage permissive -a sandbox_x_t can be used to make the
47 process type sandbox_x_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. sand‐
54 box_x policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run sandbox_x with the tightest access
56 possible.

59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69
70 setsebool -P allow_kerberos 1
71
72
73
74 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76
77 setsebool -P allow_ptrace 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83
84 setsebool -P allow_ypbind 1
85
86
87
88 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91
92 setsebool -P domain_kernel_load_modules 1
93
94
95
96 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98
99 setsebool -P fips_mode 1
100
101
102
103 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105
106 setsebool -P global_ssp 1
107
108
109
110 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112
113 setsebool -P nscd_use_shm 1
114
115
116
117 If you want to support fusefs home directories, you must turn on the
118 use_fusefs_home_dirs boolean. Disabled by default.
119
120 setsebool -P use_fusefs_home_dirs 1
121
122
123
124 If you want to support NFS home directories, you must turn on the
125 use_nfs_home_dirs boolean. Disabled by default.
126
127 setsebool -P use_nfs_home_dirs 1
128
129
130
131 If you want to support SAMBA home directories, you must turn on the
132 use_samba_home_dirs boolean. Disabled by default.
133
134 setsebool -P use_samba_home_dirs 1
135

139 The SELinux process type sandbox_x_t can manage files labeled with the
140 following file types. The paths listed are the default paths for these
141 file types. Note the processes UID still need to have DAC permissions.

193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195
196 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198
199 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201
202 semanage boolean can also be used to manipulate the booleans
203
204
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
206 icy settings.
