Browser sandboxing

(also web browser sandboxing)

Browser sandboxing definition

Browser sandboxing, alternatively termed web browser sandboxing, signifies a safety mechanism employed within web browsers designed to segregate online activity from the broader system operations. This process establishes a confined space, or a “sandbox,” where specific operations are curtailed, permitting the execution of potentially harmful scripts or applications without endangering or compromising the more extensive system.

Browser sandboxing examples

  • Web browsing: Browser sandboxing is commonly used in browsers, such as Chrome or Firefox, to prevent malicious code from a webpage from spreading onto the user's computer.
  • Online banking: Financial institutions often recommend the use of a sandboxed browser for online banking to increase security and reduce the risk of financial theft.

Advantages and disadvantages of browser sandboxing

Pros:

  • Security: Browser sandboxing can prevent malware or harmful scripts from accessing your system through your web browser.
  • Testing: Developers can use sandboxed browsers to test new code or websites in a secure environment.

Cons:

  • Limited functionality: Certain browser features may not work properly within a sandboxed environment.
  • Performance: Sandboxing may cause a slight decrease in browsing speed due to the extra resources needed to maintain the sandbox.

Using browser sandboxing

  • Ensure that your web browser has a sandboxing feature or use sandboxing software to create a safe browsing environment.
  • Remember, while browser sandboxing is a useful tool, it is not a complete security solution and should be used in conjunction with other protective measures.
