Denial of Service and Protection of Critical Infrastructure

ABSTRACT

Denial of service attacks generate massive volumes of illegitimate traffic and utilize system resources in a way that renders the system inoperable, thus denying access to authorised personnel. Denial of service attacks can be projected against systems controlling critical information infrastructure and have the potential to be an effective weapon in cyberwarfare. This paper explains the concept of a denial of service attack, discusses the different methods of achieving denial of service and looks at the impact this type of attack may have on critical infrastructure. Although there are no fail-safe ways to protect against denial of service attacks, several means of minimising damage to information systems are discussed.
