Assignment $2$: Annual Loss Expectancy

Individual

Plagarism more than $5\%$ will deduct half of the total marks.

Late submission will deduct half of total marks

You own an online store that sells and ships flowers in the Champaign$-$Urbana area. Your sales average $$600$ per day. You are worried about being targeted by a distributed denial of service $($DDOS$)$ attacker with the aim of extortion.

Such an attack would completely bring down your website, and you do not have any alternative way of doing business.

You've heard that the attacker will require on average $$1,500$ to stop the attack.

Once the money is received, the attack will stop within a day. Otherwise, it will continue for $7$ days.

Based on past data, you expect that the DDOS attackers have a $1\%$ probability of targeting your small site any particular week.

Compute the annual loss expectancy for the DDOS attack $($assuming you do nothing$).$
