NAME

6       sandbox_net_client_selinux  -  Security  Enhanced  Linux Policy for the
7       sandbox_net_client processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  sandbox_net_client  processes  via
11       flexible mandatory access control.
12
13       The  sandbox_net_client processes execute with the sandbox_net_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_net_client_t
20
21
22

ENTRYPOINTS

24       The sandbox_net_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_net_client_t  domain  are
28       the following:
29
30       all files on the system, /usr/share/sandbox/start
31

PROCESS TYPES

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_net_client  policy  is  very  flexible  allowing users to setup
40       their sandbox_net_client processes in as secure a method as possible.
41
42       The following process types are defined for sandbox_net_client:
43
44       sandbox_net_client_t
45
46       Note: semanage permissive -a sandbox_net_client_t can be used  to  make
47       the process type sandbox_net_client_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.

51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  sand‐
54       box_net_client policy is extremely flexible and  has  several  booleans
55       that allow you to manipulate the policy and run sandbox_net_client with
56       the tightest access possible.
57
58
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.

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 deny any process from ptracing or debugging any other

79       default.
80
81       setsebool -P deny_ptrace 1
82
83
84
85       If  you  want  to  allow  any  process  to mmap any file on system with
86       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
87       ean. Enabled by default.
88
89       setsebool -P domain_can_mmap_files 1
90
91
92
93       If  you want to allow all domains write to kmsg_device, while kernel is
94       executed with systemd.log_target=kmsg parameter, you must turn  on  the
95       domain_can_write_kmsg boolean. Disabled by default.

105
106
107
108       If you want to allow all domains to have the kernel load  modules,  you
109       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
110       default.
111
112       setsebool -P domain_kernel_load_modules 1
113
114
115
116       If you want to allow all domains to execute in fips_mode, you must turn
117       on the fips_mode boolean. Enabled by default.
118
119       setsebool -P fips_mode 1
120
121
122
123       If you want to enable reading of urandom for all domains, you must turn
124       on the global_ssp boolean. Disabled by default.
125
126       setsebool -P global_ssp 1
127
128

130       If you want to allow confined applications to run  with  kerberos,  you
131       must turn on the kerberos_enabled boolean. Enabled by default.
132

221       semanage  fcontext  can also be used to manipulate default file context
222       mappings.
223

228       icy modules.
229
