A new firefox extension from Carnegie-Mellon University provides protection from some recent web security threats.
Perspectives is a new approach to help clients securely identify Internet servers in order to avoid "man-in-the-middle" attacks. Perspectives is simple and cheap compared to existing approaches because it automatically builds a robust database of network identities using lightweight network probing by "network notaries" located in multiple vantage points across the Internet.
The extension provides two primary benefits:
1. If you connect to a website with an untrusted (e.g.,self-signed certificate)*, Firefox will give you a very nasty security error and force you to manually install an exception. Perspectives can detect whether a self-signed certificate is valid, and automatically overrides the annoying security error page if it is safe to do so.
2. It is possible that an attacker may trick one of the many Certificate Authorities trusted by Firefox into incorrectly issuing a certificate for a trusted website. Perspectives can also detect this attack and will warn you if things look suspicious.
