Denial-of-Service (DoS) / Distributed-Denial-of-Service (DDoS)
Denial-of-service, DoS, and distributed-denial-of-service, DDoS, attacks aim to make a website, service, or network resource unavailable to legitimate users by overwhelming it with traffic or requests, often using compromised systems (botnets). While not directly prevented by user awareness, understanding such threats contributes to a broader security culture.
