- Blue Security attack linked to blog crashes
- DDOS not redirected, secondary attackBlue Security did not redirect their traffic in response to the initial DDOS. They redirected after their IP addresses were blackholed. Once they were blackholed the initial DDOS attack was called off by the attacker. After the attacker found Blue Security was up again at their...

- Simple Solution
- I have a couple of simple solutions that would stop DDoS attacks, DOS attacks, worms, viruses, and spam:Firing squads for the offenders and banishing from the Internet any ISP that didn't cooperate with tracking down the culprits, along with life sentences for their CEOs and any employees involved for obstruction...

- Why DoS and DDoS attacks are the plague of the Internet
- Could DDoS be stopped?If ISPs simply denied "flooding" to go outside of their networks??ISPs now often have variable bandwidth allowances for users (DSL, cablemodem) based on the package they pay for to limit their bandwidth.Could an ISP not configure their network to allow only a limited amount of DDoS-style protocol...

- DDoS Threatens Financial Institutions - Get Prepared!
- Hackers that know how to create spam machines or spyware can generate DDoS attacks. In addition, a DDoS attack is generated with the help of many potentially hundreds of thousands unsuspecting zombie machines and it is not possible to stop the DDoS or protect your network with traditional security measures....

- 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....

- Defeating DDoS Attacks
- Distributed denial-of-service DDoS attacks are a real - and growing - threat to businesses worldwide. Designed to elude detection by today's most popular tools, these attacks can quickly incapacitate a targeted business, costing victims thousands, if not millions, of dollars in lost revenue and productivity. By adopting new purpose-built solutions...

- 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...

- 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...

- 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,...
