Summary

Hide ▲

Browser extensions, often overlooked, pose significant security risks due to their ability to execute privileged code, access sensitive data, and intercept network requests. These risks are exacerbated by the potential for supply chain attacks and compromised developer accounts. Keep Aware has released a Buyer’s Guide to Browser Extension Management to help security and IT leaders achieve comprehensive visibility and control over browser environments and extensions. The guide compares various management approaches, highlighting their strengths and limitations. Browser extensions can observe and modify user activity, run persistent scripts, inject JavaScript into web apps, and access sensitive data, making them a significant risk vector. Even trusted extensions can become compromised, turning them into active threats. Effective management of these extensions is crucial for maintaining enterprise security.
