Distributed system are normally untrusted
Standalone Antivirus
environments
Security suits `
Establishing secure processing
Sandboxes
environments
is very time consuming (common)
We have found a suitable technology for
lightweight secure environemnts in large
scale systems


In computer security, a sandbox is a security
mechanism for separating running programs. It is
often used to execute untested code, or untrusted
programs from unverified third-parties, suppliers
and untrusted users.”
Process virtual machine
By my survey:

A jail that can override and modify the behaviour
of system calls without change in real system

Interception
13/36


Base of sandboxes
Process interception
 system

call interception
Os:
 Unix:
ptrace OR…
 Windows: dll injection

Monitoring resources and controlling them
Sandbox technology present by Arash Karami
User level sandbox
14/36




Trace system calls
Using ptrace in Unix
Using injection to address space of
processes in windows.
For example:
 Gridbox
 Chromium
sandbox project
 Chroot
 Janus

Kernel level sandbox
15/36





Create a driver or kernel modules for a
specific platform
Low level programming
Dirty programming!!!
Non-hacked (than to user mode)
For example
 BlueBox
 EVM
 Condor
Sandbox technology present by Arash Karami
Access Control List
16/36



Assign a task, role, system call
Change system call with real system call
Example:
 Gridbox:
 Define
acl.c + syscalls.c for resource management

Application sandboxes




Move desktop app to web app
Protecting with lightweight , secure,
flexible approach (WHERE???)
Extension or separated program
 Sandboxie
A
part of Applets
 SilverLight
