Brandon Moore LOT2 Task 1 09/14/2011 Diagram Below is a diagram which illustrates how the attack overwhelmed the Web Server. Executive Summary The attack performed on the network had the intention of making the online services provided to students unusable during a critical time of need for those systems. The attack was first performed by acquiring the Administrator password for the systems and using each system to perform a large quantity of requests for service

Recent Denial of Service Summary & Recommendations “DoS (Denial of Service) attacks target network bandwidth or connectivity. Bandwidth attacks overflow the network with a high volume of traffic using existing network resources, thus depriving the legitimate users of these resources. Connectivity attacks overflow a computer with a large amount of connection requests, consuming all available operating system resources so that the computer cannot process legitimate user's requests.” (EC-COUNCIL

Hacking Countermeasures & Techniques Distributed Denial of Service (DDoS) Best Practices Guide to Counter DDoS attacks: This Guide will cover Best Practices to counter DDoS attacks like the attack on the Universities Registration System Server (RSS) by infected computers (Bots). The attack by rogue software installed on computers located in University Computer Labs resulted in the shutting down web access to the RSS system. Coordinated by a central controller these Bots established web connections

DDoS Attack Mitigation Username Online College Distributed Denial of Service (DDoS) attacks have been causing internet disruption for years. The types and frequency has evolved over time (The Growing Threat, 2012). Originally, multiple machines would ping a machine and take up its resources. Then attackers started to use the TCP handshake as an attack medium. They would request so many connections, that there would be none left for legitimate users. Now, the DDoS attacks are hitting at

Recently the university web-based registration system was the subject of a DDoS (Distributed Denial of Service) attack. This type of attack is characterized by flooding the target system(s) with more network traffic than it can process, thereby forcing the system offline or limiting its ability to respond to legitimate traffic to a negligible level. It is different from a DoS (Denial of Service), in that multiple computers (potentially thousands) are used to increase the amount of traffic sent

Best Practices Guide for DoS/DDoS Prevention In this document are guidelines that can be implemented in order to prevent future Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks on the university. No one individual practice, contained in this guide, will act as a perfect form of prevention, but will instead act as an additional layer of security. By combining these practices, the chances of another DoS/DDoS attack succeeding will be greatly diminished. Acceptable Use Policies
