Question

You have determined through a risk assessment that you are vulnerable to a distributed denial-of-service (DDoS) attack on your webserver. It turns out to prevent this attack, you would have to implement a new router with better firewall tools. If you get attacked now, it would require manual intervention and would cost you about $5,000 to mitigate the attack. Implementing a new firewall would cost $10,000 and would stop any attack automatically. You estimate that you get 4 attacks a year. How much money would you save a year by implementing better firewall tools?(1 point)

Answer 1

To determine how much money you would save by implementing better firewall tools, we first need to calculate the total cost of dealing with DDoS attacks without the new firewall, and then compare it to the cost of implementing the firewall.

1. **Cost of mitigation per attack**: $5,000
2. **Number of attacks per year**: 4

So, the total cost of mitigating attacks without the firewall each year would be:
\[
\text{Total cost without firewall} = \text{Cost per attack} \times \text{Number of attacks}
\]
\[
= 5,000 \times 4 = 20,000
\]

3. **Cost of implementing the new firewall**: $10,000

Now, we can compare the costs:

- Total annual cost of attacks without the firewall: $20,000
- Annual cost of the new firewall: $10,000

4. **Annual savings if the firewall is implemented**:
\[
\text{Savings} = \text{Total cost without firewall} - \text{Cost of firewall}
\]
\[
= 20,000 - 10,000 = 10,000
\]

Therefore, by implementing better firewall tools, you would save **$10,000** a year.

The correct response is:
**$10,000**
