Feedback control is an important element in the engineering of stable 'Internet services. However, feedback channels are vulnerable to various Internet attacks. This paper shows analytically that the recently proposed low-rate denial-of-service (DoS) attacks can degrade Internet services by generating intermittent false feedback signals. The effectiveness of the attacks is evaluated using a control-theoretic approach for a general feedback control system and detailed analysis for a specific system. A nonparametric algorithm based on changes in traffic distribution is proposed for detecting attacks.
