NAME

6       sandbox_web_selinux  -  Security  Enhanced  Linux  Policy for the sand‐
7       box_web processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sandbox_web processes via  flexible
11       mandatory access control.
12
13       The  sandbox_web processes execute with the sandbox_web_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_web_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_web policy is very flexible allowing users to setup their sand‐
31       box_web processes in as secure a method as possible.
32
33       The following process types are defined for sandbox_web:
34
35       sandbox_web_t, sandbox_web_client_t
36
37       Note: semanage permissive -a sandbox_web_t can  be  used  to  make  the
38       process  type sandbox_web_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_web_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_web_t:s0:c1,c2,
52       and  another  process launched with sandbox_web_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_web policy is extremely flexible and has several booleans that  al‐
62       low  you to manipulate the policy and run sandbox_web with the tightest
63       access possible.
64
65
66
67       If you want to deny user domains applications to map a memory region as
68       both  executable  and  writable,  this  is dangerous and the executable
69       should be reported in bugzilla, you must turn on the deny_execmem bool‐
70       ean. Enabled by default.
71
72       setsebool -P deny_execmem 1

MANAGED FILES

77       The  SELinux  process  type sandbox_web_t can manage files labeled with
78       the following file types.  The paths listed are the default  paths  for
79       these  file  types.  Note the processes UID still need to have DAC per‐
80       missions.
81
82       fusefs_t
83
84            /var/run/user/[^/]*/gvfs

COMMANDS

115       semanage fcontext can also be used to manipulate default  file  context
116       mappings.
117
118       semanage  permissive  can  also  be used to manipulate whether or not a
119       process type is permissive.
120
121       semanage module can also be used to enable/disable/install/remove  pol‐
122       icy modules.
123
124       semanage boolean can also be used to manipulate the booleans
125
126
127       system-config-selinux is a GUI tool available to customize SELinux pol‐
128       icy settings.
