  4. What is port scanning used for in security assessments?

    Answer: Identifying open ports and services running on a target system

    Port scanning identifies which ports are open on a system and what services are listening, helping security teams discover potential attack surfaces.

  5. What does NAT (Network Address Translation) primarily do?

    Answer: Translates private internal IP addresses to a public IP address for internet access

    NAT translates private internal IP addresses to a public IP address, allowing multiple internal devices to share a single public IP for internet access.

  6. What is the purpose of network traffic encryption?
