11. Summarise a network attack
Learning Objective 4

12. 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?

Include a diagram of this attack (if possible)
Recommend ways the attack can be mitigated
