Rebound Security did not install anti-malware software on its web server due to performance concerns. Unfortunately, malware infected this web server several times this past year which led to multiple outages on the web server. Deploying anti-malware software costs $500 and would prevent 80% of the infections. The total downtime was 10 hours. The web server generates $1,000 of revenue every hour of uptime. Indirect losses (e.g. advertising, brand damage) from the outages is estimated to be $15,000. What is the cost-benefit analysis for deploying anti-malware software on this web server?
