NAME

6       sandbox_net_selinux  -  Security  Enhanced  Linux  Policy for the sand‐
7       box_net processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sandbox_net processes via  flexible
11       mandatory access control.
12
13       The  sandbox_net processes execute with the sandbox_net_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_net_t

PROCESS TYPES

24       SELinux defines process types (domains) for each process running on the
25       system
26
27       You can see the context of a process using the -Z option to ps
28
29       Policy governs the access confined processes have  to  files.   SELinux
30       sandbox_net policy is very flexible allowing users to setup their sand‐
31       box_net processes in as secure a method as possible.
32
33       The following process types are defined for sandbox_net:
34
35       sandbox_net_t, sandbox_net_client_t
36
37       Note: semanage permissive -a sandbox_net_t can  be  used  to  make  the
38       process  type sandbox_net_t permissive. SELinux does not deny access to
39       permissive process types, but the AVC (SELinux  denials)  messages  are
40       still generated.

MCS Constrained

44       The  SELinux process type sandbox_net_t is an MCS (Multi Category Secu‐
45       rity) constrained type.  Sometimes this separation is  referred  to  as
46       sVirt.  These types are usually used for securing multi-tenant environ‐
47       ments, such as virtualization, containers or separation of users.   The
48       tools used to launch MCS types, pick out a different MCS label for each
49       process group.
50
51       For example one process might be launched with  sandbox_net_t:s0:c1,c2,
52       and  another  process launched with sandbox_net_t:s0:c3,c4. The SELinux
53       kernel only allows these processes can only write  to  content  with  a
54       matching  MCS  label,  or a MCS Label of s0. A process running with the
55       MCS level of s0:c1,c2 is not allowed to write to content with  the  MCS
56       label of s0:c3,c4

BOOLEANS

60       SELinux  policy  is customizable based on least access required.  sand‐
61       box_net policy is extremely flexible  and  has  several  booleans  that
62       allow  you to manipulate the policy and run sandbox_net with the tight‐
63       est access possible.
64
65
66
67       If you want to allow users to resolve user passwd entries directly from
68       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
69       gin_nsswitch_use_ldap boolean. Disabled by default.
70
71       setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75       If you want to deny user domains applications to map a memory region as
76       both  executable  and  writable,  this  is dangerous and the executable
77       should be reported in bugzilla, you must turn on the deny_execmem bool‐
78       ean. Enabled by default.
79
80       setsebool -P deny_execmem 1
81
82
83
84       If you want to allow all domains to execute in fips_mode, you must turn
85       on the fips_mode boolean. Enabled by default.
86
87       setsebool -P fips_mode 1
88
89
90
91       If you want to allow confined applications to run  with  kerberos,  you
92       must turn on the kerberos_enabled boolean. Enabled by default.
93
94       setsebool -P kerberos_enabled 1
95
96
97
98       If  you  want  to  allow  system  to run with NIS, you must turn on the
99       nis_enabled boolean. Disabled by default.
100
101       setsebool -P nis_enabled 1
102
103
104
105       If you want to allow confined applications to use nscd  shared  memory,
106       you must turn on the nscd_use_shm boolean. Enabled by default.
107
108       setsebool -P nscd_use_shm 1
109

MANAGED FILES

113       The  SELinux  process  type sandbox_net_t can manage files labeled with
114       the following file types.  The paths listed are the default  paths  for
115       these  file  types.  Note the processes UID still need to have DAC per‐
116       missions.
