Security :: Uncovering Covert Command-and-Control Channels?

Quote:As the line between securely hosted and controlled enterprise applications and cloud-based applications continues to blur, there's more "legitimate" traffic between corporate networks and the Internet than ever before. This opens up new vectors for attack by hackers nd cybercriminals as more traffic types are allowed through corporate firewalls. The result is an increase in diversity of covert command and control channels, which hide inside legitimate traffic in order to bypass perimeter security. These C&C channels, used by malware ranging from simple spambots to more sophisticated rootkits, vary in the maliciousness of their intent from casual hacking all the way to advanced persistent threats (APT) and industrial espionage.
