Nathan is testing some of his network devices. Nathan is using Macof to try and flood the ARP cache of these switches. If these switches' ARP cache is successfully flooded, what will be the result?
Bob was frustrated with his competitor, Brownies Inc., and decided to launch an attack that would result in serious financial losses. He planned the attack carefully and carried out the attack at the appropriate moment.
Meanwhile, Trent, an administrator at Brownies Inc., realized that their main financial transaction server had been attacked. As a result of the attack, the server crashed and Trent needed to reboot the system, as no one was able to access the resources of the company. This process involves human interaction to fix it.
What kind of Denial of Service attack was best illustrated in the scenario above?
When a normal TCP connection starts, a destination host receives a SYN (synchronize/start) packet from a source host and sends back a SYN/ACK (synchronize acknowledge). The destination host must then hear an ACK (acknowledge) of the SYN/ACK before the connection is established. This is referred to as the "TCP three-way handshake." While waiting for the ACK to the SYN ACK, a connection queue of finite size on the destination host keeps track of connections waiting to be completed. This queue typically empties quickly since the ACK is expected to arrive a few milliseconds after the SYN ACK. How would an attacker exploit this design by launching TCP SYN attack?
