Find different network attacks Learning Objective 2

A group of interconnected (via cable and/or wireless) computers and peripherals that is capable of sharing software and hardware resources between many users. The Internet is a global network of networks. What is a Network?

What is Network Security? Network security is the process by which digital information are protected What is Network Security?

The first computer viruses were developed in the early 1980s. The first viruses found in the wild were Apple II viruses, such as Elk Cloner, which was reported in 1981 A little history

Task Create an a-z of network attacks poster (pairs). See if you can find 26 different attacks! Organise the attacks into highest to lowest impact the attack has on a network Task

Define network attacks Learning Objective 3

Attacks Denial of service Back door Spoofing Mathematical Brute force Adware. Software exploitation Viruses Rootkits Worms Trojans Spyware Attacks

Task In pairs, create a presentation that defines the following: There are many different types of network attacks, for the following: research online and define the type of attack. In pairs, create a presentation that defines the following: denial of service, back door, spoofing, mathematical, brute force, adware. Your definition should be no more than 1 sentence/20 words. software exploitation, viruses, rootkits, worms, Trojans, spyware, Task Research into the most prolific malware / attacks which were written by teenagers! Write some information down about them – Name of attack/malware, data, damage caused (cost) etc. Present - presentation, report

Summarise a network attack Learning Objective 4

Choose 3 types of threats that attack a network, summarise each attack. Why is it a dangerous type of attack? When is a company usually susceptible to this type of attack? Who normally perpetrates this type of attack? Include a diagram of this attack (if possible) Recommend ways the attack can be mitigated Task
