PLP Minor in Cybersecurity: LU2_Week 7

In computer networking, promiscuous mode is a mode of operation, as well as a security, monitoring and administration technique. In promiscuous mode, a network device, such as an adapter on a host system, can intercept and read in its entirety each network packet that arrives

A UDP flood is a form of volumetric Denial-of-Service (DoS) attack where the attacker targets and overwhelms random ports on the host with IP packets containing User Datagram Protocol (UDP) packets. In this type of attack, the host looks for applications associated with these datagrams. When none are found, the host issues a “Destination Unreachable” packet back to the sender. The cumulative effect of being bombarded by such a flood is that the system becomes inundated and therefore unresponsive to legitimate traffic.

In a UDP flood DDoS attack, the attacker may also choose to spoof the IP address of the packets. This ensures that the return ICMP packets are not able to reach their host, while also keeping the attack completely anonymous.

IP fragmentation attacks are a common form of denial of service attack, in which the perpetrator overbears a network by exploiting datagram fragmentation mechanisms.

Understanding the attack starts with understanding the process of IP fragmentation, a communication procedure in which IP datagrams are broken down into small packets, transmitted across a network and then reassembled back into the original datagram.

In this video, we'll explore the basics of packet sniffing, a technique used to intercept and analyze network traffic.

This video is about ARP Poisoning.

Wireshark is a network sniffer software that is used to spy into the targeted user's network traffic and look into the user's data packets that are transferred over the network.

ICMP, or Internet Control Message Protocol, is an error-reporting protocol used by routers, hosts, and other network devices to communicate error information or updates to other routers, hosts, and network devices.
