SlowITe, a Novel Denial of Service Attack Affecting MQTT

Denial of Service Attack and Defense

In this chapter, we firstly review the short history of denial of service (DoS) and distributed denial of service (DDoS) attacks. We further explore the reasons why the current cyberspace is a heaven for cyber criminals, such as DDoS attackers. We present the challenges of the DDoS related research fields from various aspects, and discuss the possible research methods and strategies to serve th...

Analysis of a Denial of Service Attack on TCP

This paper analyzes a network-based denial of service attack for IP (Internet Protocol) based networks. It is popularly called SYN flooding. It works by an attacker sending many TCP (Transmission Control Protocol) connection requests with spoofed source addresses to a victim’s machine. Each request causes the targeted host to instantiate data structures out of a limited pool of resources. Once ...

A Denial of Service Attack on the Java Bytecode Verifier∗

Java Bytecode Verification was so far mostly approached from a correctness perspective. Security vulnerabilities have been found repeatedly and were corrected shortly thereafter. However, correctness is not the only potential point of failure in the verifier idea. In this paper we construct Java code, which is correct, but requires an excessive amount of time to prove safety. In contrast to pre...

Defending against a Denial-of-Service Attack on TCP

In this paper we propose a method for detecting TCP SYN-flooding attacks. This is an anomaly detection method based on intensities of SYN segments which are measured on a network monitoring machine in real-time. We note that current solutions suffer from several important flaws such as the possibility of denying access to legitimate clients and/or causing service degradation at protected machin...
