Network scanning is used primarily for what purpose?

• A. Establishing internet connectivity
• B. Performing detailed reconnaissance
• C. Creating firewalls
• D. Encrypting data transmissions

Answer: (B)

Network scanning is a crucial aspect of penetration testing and ethical hacking, primarily used for performing detailed reconnaissance. This process involves discovering active hosts, services, and vulnerabilities within a network, helping cybersecurity professionals gather necessary information about the system’s layout and security posture. By conducting network scans, ethical hackers can identify weaknesses that may be exploited by malicious actors. This reconnaissance allows them to map out the network's structure and pinpoint specific devices and services running on those devices, which is foundational for any subsequent testing and securing of the network. Other options do not align with the primary purpose of network scanning. Establishing internet connectivity relates more to networking fundamentals and infrastructure setup rather than reconnaissance. Creating firewalls is focused on establishing defensive barriers against network threats rather than gathering information about the network, while encrypting data transmissions pertains to securing data rather than discovering vulnerabilities. Hence, the emphasis on reconnaissance underlines why the correct choice is focused on detailed scanning efforts.
