George is performing a risk analysis on a potential DoS $($Denial of Service$)$ attack against his company's web server, which sells Widgets. The company's web server is valued at $$100,000.$ George estimates that if a DoS $1$ points

attack occurs, it would render the server unusable for a few hours, resulting in a $25\%$ loss of functionality during that time. The company's financial loss due to lost sales, recovery costs, and other factors is expected to be

$$15,000$ per incident. George estimates that such an attack could occur twice per year. What is the Single Loss Expectancy $($SLE$)$ for the DoS attack?
