Which type of attack floods a network with excessive traffic to render a service unavailable?

Question

Options

• ASQL Injection
• BPhishing
• CDenial of Service (DoS)
• DMan-in-the-middle

• B
  5% (2)
• C
  92% (34)
• D
  3% (1)

Explanation

Denial of Service (DoS) works by overwhelming a target system or network with more traffic than it can handle, exhausting resources (bandwidth, memory, CPU) until legitimate users can't access the service - exactly what the question describes.

• SQL Injection (A) targets databases by inserting malicious SQL code into input fields to manipulate or exfiltrate data - it exploits logic, not traffic volume.
• Phishing (B) is a social engineering attack that tricks users into revealing credentials or clicking malicious links - it targets people, not network capacity.
• Man-in-the-middle (D) secretly intercepts and potentially alters communication between two parties - it's about eavesdropping or tampering, not flooding.

Memory tip: Think "Denial = Denied access." DoS denies service by drowning it in traffic, like a crowd blocking a store entrance so no real customers can get in.
