- DDoS-Resilient Scheduling to Counter Application Layer Attacks Under Imperfect Detection
- Countering Distributed Denial of Service DDoS attacks is becoming ever more challenging with the vast resources and techniques increasingly available to attackers. This paper considers sophisticated attacks that are protocol-compliant, non-intrusive, and utilize legitimate application-layer requests to overwhelm system resources. The authors characterize application layer resource attacks as either request...

- Anti-DDoS Virtualized Operating System
- It is easier to detect a DDoS attack near the victim but it is of little use to do so. Many researchers believe that it would be best to handle DDoS attacks closer to the computers which host these attacks and have propounded various strategies for packet filtering at edge-routers....

- TCP Flow Analysis for Defense Against Shrew DDoS Attacks
- The shrew or RoS attacks are low-rate DDoS attacks that degrade the QoS to end systems slowly but not to deny the services completely. These attacks are more difficult to detect than the flooding type of DDoS attacks. This paper explores the energy distributions of Internet traffic flows in frequency...

- An Integrated Framework for Proactive Mitigation, Characterization and Traceback of DDoS Attacks
- Denial of Service DoS attacks pose a severe security threat to the steady functioning of any network. These attacks aim at depleting the resources of a server or an administrative network by overwhelming it with enormous and useless traffic. The outcome of this is the fact that legitimate users are...

- DIADEM Firewall: Web Server Overload Attack Detection and Response
- High-profile web servers often become the victim of web server overload Distributed Denial-of-Service DDoS attacks. Motivations of such attacks range from technical challenge (e.g. script kiddies) to financial profit (e.g. blackmailing the web server's owner). This paper presents the DIADEM Firewall architecture that allows an ISP to protect its customers...

- Mitigate the effects of a DDoS attack
- There's a great variety of attacks and hacks that black hats can perpetrate on your network. Fortunately, you can prevent most of them using an assortment of security measures.However, a distributed denial-of-service attack DDoS is an entirely different story. You can't thwart a DDoS attack -- they attack an IP...

- Victim-Assisted Mitigation Technique for TCP-Based Reflector DDoS Attacks
- This paper develops the concept of victim-assistance for Denial of Service DoS mitigation. The proposed concept is utilized within a simple, yet effective scheme designed for mitigating TCP-based reflector DoS attacks. The proposed scheme, called SYN number based filtering SNF, takes into account the TCP's connection establishment behavior and the...

- Detecting DDoS Attacks on ISP Networks
- Most past solutions for detecting denial of service attacks and identifying the perpetrators have targeted end-node victims. However, little attention has been given to this problem from an ISP perspective. This paper explores the key challenges involved in helping an ISP network detect attacks on itself or attacks on external...

- Protecting Public Servers From DDoS Attacks Using Drifting Overlays
- Drifting Overlays are dynamic partial network-layer overlays with traffic 'Safe houses' that enterprises can use to control, at fine granularity, the reachability and predictability of paths taken to important hosts. Drifting Overlays enable enterprises a level of control over their own Distributed Denial of Service DDoS defenses and routing choices,...
