You are the risk professional of your enterprise.
You need to calculate potential revenue loss if a certain risks occurs.

A. B. C. D.B.
Denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users.
Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely.
Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root name-servers.
The term is generally used with regards to computer networks, but is not limited to this field; for example, it is also used in reference to CPU resource management.
As the total revenue of the website for the day is $1 million, and due to denial of service attack it is unavailable for half day.
Therefore, Revenue loss = $1,000,000/2 - = $500,000 Incorrect Answers: A, C, D: These are wrong answers.
To calculate the potential revenue loss in the event of a DoS attack on an e-commerce website, we need to consider the following factors:
Daily revenue generated by the website: In this scenario, the website is generating US $1 million of revenue each day.
Duration of the DoS attack: The duration of the attack is given as half a day.
Impact of the DoS attack: The impact of the DoS attack on the website's revenue will depend on the percentage of traffic that is affected by the attack. In a DoS attack, the attacker floods the website with traffic, making it inaccessible to legitimate users. Therefore, the revenue loss will be proportional to the percentage of traffic that is affected by the attack.
Assuming that the DoS attack affects 50% of the website's traffic, the potential revenue loss can be calculated as follows:
Daily revenue = US $1 million Revenue per hour = Daily revenue / 24 hours = US $1 million / 24 = US $41,667 Revenue per half day (12 hours) = Revenue per hour x 12 = US $41,667 x 12 = US $500,004 Revenue loss due to DoS attack = 50% x Revenue per half day = 50% x US $500,004 = US $250,002
Therefore, the potential revenue loss if a DoS attack occurs that lasts half a day and affects 50% of the website's traffic is US $250,002.
So, the answer is option A: US $250,000 loss.
