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 The sandbox_min_client_t SELinux type can be entered via the file_type,
25 sandbox_exec_t file types.
26
27 The default entrypoint paths for the sandbox_min_client_t domain are
28 the following:
29
30 all files on the system, /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_min_client policy is very flexible allowing users to setup
40 their sandbox_min_client processes in as secure a method as possible.
41
42 The following process types are defined for sandbox_min_client:
43
44 sandbox_min_client_t
45
46 Note: semanage permissive -a sandbox_min_client_t can be used to make
47 the process type sandbox_min_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_min_client policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run sandbox_min_client with
56 the tightest access possible.
57
58
59
60 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64
65 setsebool -P deny_execmem 1
66
67
68
69 If you want to deny any process from ptracing or debugging any other
70 processes, you must turn on the deny_ptrace boolean. Enabled by
71 default.
72
73 setsebool -P deny_ptrace 1
74
75
76
77 If you want to allow any process to mmap any file on system with
78 attribute file_type, you must turn on the domain_can_mmap_files bool‐
79 ean. Enabled by default.
80
81 setsebool -P domain_can_mmap_files 1
82
83
84
85 If you want to allow all domains write to kmsg_device, while kernel is
86 executed with systemd.log_target=kmsg parameter, you must turn on the
87 domain_can_write_kmsg boolean. Disabled by default.
88
89 setsebool -P domain_can_write_kmsg 1
90
91
92
93 If you want to allow all domains to use other domains file descriptors,
94 you must turn on the domain_fd_use boolean. Enabled by default.
95
96 setsebool -P domain_fd_use 1
97
98
99
100 If you want to allow all domains to have the kernel load modules, you
101 must turn on the domain_kernel_load_modules boolean. Disabled by
102 default.
103
104 setsebool -P domain_kernel_load_modules 1
105
106
107
108 If you want to allow all domains to execute in fips_mode, you must turn
109 on the fips_mode boolean. Enabled by default.
110
111 setsebool -P fips_mode 1
112
113
114
115 If you want to enable reading of urandom for all domains, you must turn
116 on the global_ssp boolean. Disabled by default.
117
118 setsebool -P global_ssp 1
119
120
121
122 If you want to support fusefs home directories, you must turn on the
123 use_fusefs_home_dirs boolean. Disabled by default.
124
125 setsebool -P use_fusefs_home_dirs 1
126
127
128
129 If you want to support NFS home directories, you must turn on the
130 use_nfs_home_dirs boolean. Disabled by default.
131
132 setsebool -P use_nfs_home_dirs 1
133
134
135
136 If you want to support SAMBA home directories, you must turn on the
137 use_samba_home_dirs boolean. Disabled by default.
138
139 setsebool -P use_samba_home_dirs 1
140
141
142
144 The SELinux process type sandbox_min_client_t can manage files labeled
145 with the following file types. The paths listed are the default paths
146 for these file types. Note the processes UID still need to have DAC
147 permissions.
148
149 cifs_t
150
151
152 fusefs_t

174 semanage fcontext can also be used to manipulate default file context
175 mappings.
176
177 semanage permissive can also be used to manipulate whether or not a
178 process type is permissive.
179
180 semanage module can also be used to enable/disable/install/remove pol‐
181 icy modules.
182
183 semanage boolean can also be used to manipulate the booleans
184

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