For this exercise, you will perform research and develop a brief paper on the subject described below. A Denial of Service (DOS) attack typically involves the misuse of standard TCP/IP protocols or connection processes so that the target for the DOS attack responds in a way designed to create maximum trouble. Read the TECHNICAL FOCUS 11-2 ‘Inside a DoS Attack’ on page 299 and become familiar with the five common types of TCP/IP attacks. Select one attack method and conduct research using the Internet and libraries available through your Cougar-Track account to develop a 900-1000-word (approximately 4 single-space pages) narrative of an actual attack that used the method you selected. Use the following list of significant points to consider as you create your paper. Why was the target selected? (For social, political, financial reasons?) What was the target’s network security posture prior to the attack? (Passively/Actively protected, indifferent about cybersecurity?) What was the loss to the target? (Information, financial data, customer/personal information?) What secondary impact did the attack have, and to whom? (Banks, investments, suppliers, etc.) Identify the person or organization that claimed responsibility for the attack. In your own words, describe why you believe they performed the attack. TECHNICAL FOCUS 11-2 Inside a DoS Attack A DoS attack typically involves the misuse of standard TCP/IP protocols or connection processes so that the target for the DoS attack responds in a way designed to create maximum trouble. Five common types of attacks include the following: • ICMP Attacks The network is flooded with ICMP echo requests (i.e., pings) that have a broadcast destination address and a faked source address of the intended target. Because it is a broadcast message, every computer on the network responds to the faked source address so that the target is overwhelmed by responses. Because there are often dozens of computers in the same broadcast domain, each message generates dozens of messages at the target. • UDP Attacks This attack is similar to an ICMP attack, except that it uses UDP echo requests instead of ICMP echo requests. • TCP SYN Floods The target is swamped with repeated SYN requests to establish a TCP connection, but when the target responds (usually to a faked source address), there is no response. The target continues to allocate TCP control blocks, expects each of the requests to be completed, and gradually runs out of memory. • UNIX Process Table Attacks This is similar to a TCP SYN flood, but instead of TCP SYN packets, the target is swamped by UNIX open connection requests that are never completed. The target allocates open connections and gradually runs out of memory. Finger of Death Attacks This is similar to the TCP SYN flood, but instead the target is swamped by finger requests that are never disconnected. • DNS Recursion Attacks The attacker sends DNS requests to DNS servers (often within the target’s network) but spoofs the from address so the requests appear to come from the target computer that is overwhelmed by DNS responses. DNS responses are larger packets than ICMP, UDP, or SYN responses, so the effects can be stronger. .
