Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress
Order Code RL32114 Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress Updated January 29, 2008 Clay Wilson Specialist in Technology and National Security Foreign Affairs, Defense, and Trade Division Botnets, Cybercrime, and Cyberterrorism: Vulnerabilities and Policy Issues for Congress Summary Cybercrime is becoming more organized and established as a transnational business. High technology online skills are now available for rent to a variety of customers, possibly including nation states, or individuals and groups that could secretly represent terrorist groups. The increased use of automated attack tools by cybercriminals has overwhelmed some current methodologies used for tracking Internet cyberattacks, and vulnerabilities of the U.S. critical infrastructure, which are acknowledged openly in publications, could possibly attract cyberattacks to extort money, or damage the U.S. economy to affect national security. In April and May 2007, NATO and the United States sent computer security experts to Estonia to help that nation recover from cyberattacks directed against government computer systems, and to analyze the methods used and determine the source of the attacks.1 Some security experts suspect that political protestors may have rented the services of cybercriminals, possibly a large network of infected PCs, called a “botnet,” to help disrupt the computer systems of the Estonian government. DOD officials have also indicated that similar cyberattacks from individuals and countries targeting economic, -

A Double Horizon Defense Design for Robust Regulation of Malicious Traffic Abstract Deploying defense mechanisms in routers holds promises for protecting infrastructure resources such as link bandwidth or router buffers against network Denial-of-Service (DoS) attacks. However, in spite of their efficacy against bruteforce flooding attacks, existing outer-basedr defenses often perform poorly when confronted to more sophisticated attack strategies. -

Many DDoS attack detection methods are this type attack [2, 3]. focused on the IP and TCP layers. However, they are not suitable for detecting the application layer DDoS attacks. In The challenges of detecting the app-DDoS attacks can this paper, we propose a scheme based on web user be summarized as the following aspects: browsing behaviors to detect the application layer DDoS • The app-DDoS attacks make use of higher layer attacks (app-DDoS).
