Browser Security Settings and Extensions
Configure browsers for privacy, use ad blockers, and understand HTTPS Everywhere.
Why the Browser is a Critical Attack Surface
The web browser is the most commonly used application and one of the most attacked. Browsers execute code from untrusted sources (websites), handle sensitive data, and have direct access to user credentials and sessions.
Keeping Browsers Updated
Browser vendors release security patches frequently. An outdated browser may be vulnerable to known exploits including drive-by downloads and sandbox escapes. Enable automatic updates — never delay browser updates.
