What it is
Browser security mechanisms are built-in protections such as sandboxing, same-origin policy, HTTPS enforcement, certificate validation, pop-up blocking, and phishing or malware detection. Browsers continuously evolve these features to protect users even when applications are imperfectly secured.
Why it matters
Many attacks are ultimately executed in the browser. Strong browser-level protections can prevent exploitation, data leakage, and session hijacking—even when users interact with compromised or malicious sites.
How to reduce risk
- Encourage use of modern, up-to-date browsers.
- Combine browser protections with proper server-side security controls.
- Enforce HTTPS and secure cookies across all applications.
- Educate users about browser warnings and security indicators.
