  E. The zombie's IP ID increases by 2.

  Correct Answer: ACDB

  Following are the steps required in an idle scan of a closed port:

  1.Probe the zombie's IP ID: The attacker sends a SYN/ACK to the zombie. The zombie, unaware of the SYN/ACK, sends back a RST, thus disclosing its IP ID.

  

  2.Forge a SYN packet from the zombie: In response to the SYN, the target sends a RST. The zombie ignores the unsolicited RST, and the IP ID remains unchanged.

  

  3.Probe the zombie's IP ID again: The zombie's IP ID has increased by only 1 since step 1. So the port is closed.
