These days, Internet is the most essential medium for communication which is used by many users across the Network. Together, its commercial nature is causing enhance vulnerability to increase cyber crimes and there has been an immeasurable raise in the number of Distributed Denial of Service (DDOS) attacks on the internet over the past decade. Resources of network such as web servers, network ...

The distributed denial of service (DDoS) attack that is one of the most threatening attacks in the wired network has been already extended in the wireless mobile network, owing to the appearance of DDoS attack tool against mobile phone. In the future, the latent threats for the converged form of DDoS attack should be resolved for the induction of successful convergence network. However, because...

Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks are typically explicit attempts to exhaust victim’s bandwidth or disrupt legitimate users’ access to services. Traditional architecture of internet is vulnerable to DDoS attacks and it provides an opportunity to an attacker to gain access to a large number of compromised computers by exploiting their vulnerabilities to set ...

Recent DDoS attacks against several web sites operated by SONY Playstation caused wide spread outage for several days, and loss of user account information. DDoS attacks by WikiLeaks supporters against VISA, MasterCard, and Paypal servers made headline news globally. These DDoS attack floods are known to crash, or reduce the performance of web based applications, and reduce the number of legiti...

2 Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks have increased in number. Take note: saying THAT would be a gross understatement. Back in the comfortable past, only people with specialized knowledge and a good amount of resources were able to launch such high-end attacks. Today, anyone with access to the Internet and minimal technical know-how can very well execute an...

At the beginning of the 21st century, a new form of denial of service (DoS) attack emerged which is the Distributed DoS (DDoS). This new form of attack was launched on huge number of prominent websites such as yahoo, e-bay, Amazon, and buy.com, resulting in tremendous financial loses. DDoS attack has continued to increase over the years due to the rapid increase in internet users. Moreover, eve...

1 Zero-Crossing Analysis of Lévy Walks and a DDoS Dataset for Real-Time Feature Extraction: Composite and Applied Signal Analysis for Strengthening the Internet-of-Things Against DDoS Attacks; Jesus David Terrazas Gonzalez, Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, Canada Witold Kinsner, Department of Electrical and Computer Engineering, University of ...

In this paper we discuss techniques to prevent Distributed Denial of Service (DDoS) attacks within the ISP domain and extend the scheme to prevent the attack in multiple ISP domains. With a new packet marking technique and agent design, our model is able to identify the approximate source of attack with a single packet and has many features to minimise DDoS attacks.

Large-scale network environments require effective detection and response methods against DDoS attacks. Depending on the advancement of IT infrastructure such as the server or network equipment, DDoS attack traffic arising from a few malware-infected systems capable of crippling the organization's internal network has become a significant threat. This study calculates the frequency of network-b...

While there are plenty of papers describing algorithms for detecting distributed denial of service (DDoS) attacks, here an introduction to the considerations preceding such an implementation is given. Therefore, a brief history of and introduction to DDoS attacks is given, showing that these kind of attacks are nearly two decades old. It is also depicted that most algorithms used for the detect...
