Certificate authority Trustwave issued a certificate to a company allowing it to issue valid certificates for any server. This enabled the company to listen in on encrypted traffic sent and received by its staff using services such as Google and Hotmail. Trustwave has since revoked the CA certificate and vowed to refrain from issuing such certificates in future.
If the future is heading toward "cloud computing," where most of your data lives on someone else's server, can you trust the cloud to keep a secret? Researchers say they've found a way to guarantee that your information will be secure in the cloud, using quantum entanglement.
An SED is a self-encrypting hard drive with a circuit built into the disk drive controller chip that encrypts all data to the magnetic media and decrypts all the data from the media automatically. All SEDs encrypt all the time from the factory onwards, performing like any other hard drive, with the encryption being completely transparent or invisible to the user.
