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

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

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: • software exploitation, • denial of service, • viruses, • back door, • rootkits, • spoofing, • worms, • mathematical, • Trojans, • brute force, • spyware, • adware. Your definition should be no more than 1 sentence/20 words. 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 Task

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) Task Recommend ways the attack can be mitigated
