Browser Sandboxing

A browser sandbox is an isolated execution environment designed to confine web content within strict boundaries. Modern browsers use sandboxing to limit how loaded web pages and scripts interact with the underlying operating system, and to prevent tabs from talking to each other. If an attacker exploits a flaw in the browser, the sandbox helps prevent malicious code from escaping to the larger system. In the client-side security landscape, sandboxing is one of the core mitigations against attacks like drive-by downloads and memory corruption exploits.
