Vulnerabilities



In the wake of this weekend’s revelations of the seriousness of the attack on certificate authority DigiNotar, security experts have renewed criticism of the Internet’s digital certificate infrastructure, with some wondering if larger certificate authorities (CAs) might be too big to fail.

GlobalSign, a major certificate authority that was named by the hacker who has claimed credit for the DigiNotar hack as another CA he has compromised, has stopped issuing certificates for the time being while it investigates the claims and determines whether its network has in fact been compromised. It also has hired Fox-IT, the same company that investigated the attack at DigiNotar, to perform the audit of its systems.
