Answer

Brief Explanations:

  • Port scanner: Passive security attacks involve observing or listening to network traffic without interfering. A port scanner is used to gather information about open ports on a system, which is a form of passive observation.
  • Denial - of - service attack: This is an active attack as it aims to disrupt the normal functioning of a service by overwhelming it with traffic.
  • Spoofing: It is an active attack where an attacker pretends to be someone else (e.g., by falsifying IP addresses) to gain unauthorized access or cause harm.
  • Ping of death: This is an active attack that sends malformed ping packets to crash a system.
