Protecting Critical Infrastructures from Stealth Attacks: A Closed-Loop Approach Involving Detection and Remediation - (Short Paper)

We present an architecture capable to protect Critical Infrastructures from one of the most harmful categories of Denial of Service (DoS) attacks, commonly known in the literature as either “low-rate”, or “stealth” attacks. Stealth attacks do represent the last generation of network threats, since they minimize both cost and visibility, at the same time achieving an effectiveness which is comparable to that of common brute force attacks. The study is conducted by exploiting an actual deployment of an architecture for the effective protection of Critical infrastructures, designed and developed within the INSPIRE European Project.
