6 sandbox_min_selinux - Security Enhanced Linux Policy for the sand‐
7 box_min processes
8
10 Security-Enhanced Linux secures the sandbox_min processes via flexible
11 mandatory access control.
12
13 The sandbox_min processes execute with the sandbox_min_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sandbox_min_t
20
21
22
24 The sandbox_min_t SELinux type can be entered via the file_type file
25 type.
26
27 The default entrypoint paths for the sandbox_min_t domain are the fol‐
28 lowing:
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_min policy is very flexible allowing users to setup their sand‐
40 box_min processes in as secure a method as possible.
41
42 The following process types are defined for sandbox_min:
43
44 sandbox_min_t, sandbox_min_client_t
45
46 Note: semanage permissive -a sandbox_min_t can be used to make the
47 process type sandbox_min_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_min policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sandbox_min with the tight‐
56 est access 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_min_t can manage files labeled with
140 the following file types. The paths listed are the default paths for
141 these file types. Note the processes UID still need to have DAC per‐
142 missions.

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