A single zombie PC can send 128000 / (500/8) = 32 packets per second.
About 4 such zombie systems are needed to flood a target organization using a 0.5 Megabit per second (Mbps) link.
For a 2Mbps link about 16 such zombie PCs are needed (500/32 pps).
For a 10 Mbps link about 79 such zombie PCs are needed (2500/32 pps).
Consider a variant of the previous question. Assume the attacker has compromised a number of broadband-connected...
6. (10 Points) In order to implement the classic DoS flood attack, the attacker must generate a sufficiently large volume of packets to exceed the capacity of the link to the target organization. Consider an attack using ICMP echo request (ping) packets that are 500 bytes in size (ignoring the framing overhead). (a) How many of these packets per second must the attacker send to flood a target organization using a 0.5 Mbps link? (b) How many per second if...
In order to implement a DNS amplification attack, the attacker must trigger the creation of a sufficiently large volume of DNS response packets from the intermediary to exceed the capacity of the link to the target organization. Consider an attack where the DNS response packets are 500 bytes in size (ignoring framing overhead). a. How many of these packets per second must the attacker trigger to flood a target organization using a 0.5-Mbps link? A 2-Mbps link? Or a10-Mbps link?...
- Network security QUESTION 17 We assume that a LAN network includes 7 hosts (A, B, C, D, E. Fand G) which are connected by a switch. The contents of the switch's CAM table is as follows: (Port 1. Host A) - (Port 2. Host B) - (Port 3. Host - Port 4, Host D) - Port S. Hosta-Port 6, Host F) - (Port 7. HostG), Also, we assume that there is/are one or many host(s) that has/have sent fake...
