Frequently Asked Questions

What is phishing?

Phishing is a social engineering attack where attackers send fake emails or messages pretending to be legitimate organizations to steal passwords or financial information.

How does a DDoS attack work?

A Distributed Denial of Service attack floods a server with so much fake traffic from thousands of compromised computers that legitimate users cannot access the service.

Why is encryption important?

Encryption converts data into unreadable code. Even if attackers steal encrypted data, AES-256 encryption would take billions of years to crack without the key.

Is this game accurate?

Yes. All facts are verified against NIST, CISA, and cybersecurity textbook sources.
