Covert channels pose an ever-increasing threat to protocols and security models primarily because of how insidiously they operate. They are also often overlooked when designing secure systems and tend to go unnoticed till a major leak occurs. This talk will focus on how network protocols can be exploited to introduce covert channels, will go on to analyse their bandwidth and discuss ways of keeping it down.
