Certified Ethical Hacker (CEH v13) — Question 199

While working as an intern for a small business, you have been tasked with managing the company's web server. The server is being bombarded with requests, and the company's website is intermittently going offline. You suspect that this could be a Distributed Denial of Service (DDoS) attack. As an ethical hacker, which of the following steps would be your first course of action to mitigate the issue?

Answer options

• A. Contact your Internet Service Provider (ISP) for assistance
• B. Install a newer version of the server software
• C. Implement IP address whitelisting
• D. Increase the server's bandwidth

Correct answer: A

Explanation

The correct answer is A, as contacting the ISP is crucial for addressing a DDoS attack; they can provide assistance such as traffic filtering or mitigation services. Options B, C, and D may improve server performance or security in general but do not directly address the immediate issue of a DDoS attack.
