Sandbox – Online, Offline By Pushkar Null-The Open Secuirty Community
Sandbox… Sandbox may refer to: Limited, restricted environment for a specific purpose Litter box, an indoor box for cats to relieve themselves Sandpit or sandbox, a wide, shallow playground construction to hold sand often made of wood or plastic Sandbox (railways), a container that holds sand for use in improving rail adhesion in slippery conditions Sandboxing is a popular technique for creating confined execution environments, which could be be used for running untrusted programs. A sandbox limits, or reduces, the level of access its applications have — it is a container
Sandbox… Sandbox (computer security), a virtual container in which untrusted programs can be safely run Sandbox (software development), an online environment in which code or content changes can be tested without affecting the original system Sandbox Effect, in Google Internet search rankings
How it works… Basic two mechanism… Namespace isolation - agents are unable to manipulate resources that they cannot name. Access checks - discharge proof obligations of the form “agent A may manipulate resource R by method M“ Intercepting System calls Deny the system call, Audit the system call's invocation, Pre- process the arguments, Post-process the result, Replace the system call's implementation
Limitations… Sandboxing implementations suffer from five broad kinds of limitation: too much isolation not enough isolation non-portability non-usability design and implementation failures
Google Sandbox… Sandbox Effect, Technique that google uses to ran new website in its search results Check whether it is a genuine or a spam website
