Digital Society has given an 'F' to the security of both Twitter and Facebook.

"Both sites are vulnerable to attacks that can give someone partial or full control over your account, the group claims," writes Computerworld's Jared Newman.

"According to Digital Society, the main problem with Facebook and Twitter is that neither site allows full Secure Sockets Layer (SSL) protection," Newman writes. "Both sites create unencrypted sessions for the user by default. Although the actual logins are encrypted, they're not authenticated -- which means you can't pull up security information in your browser to verify the sites' identities."
