Which type of attack floods a network or server with excessive traffic to make it unavailable to legitimate users?

Denial-of-service attacks flood a website or network with fake traffic. Legitimate users can’t access the service because it’s overwhelmed. It’s like thousands of prank callers blocking a phone line.

Phishing tricks people into revealing passwords. Man-in-the-middle intercepts communications. SQL injection attacks databases directly.

DoS attacks aim to disrupt service, not steal data. Websites go offline until the attack stops or is blocked.
