Question

You work as an IT security auditor hired by a law firm in Boston to test whether you can gain access to sensitive information about the company clients. You have rummaged through their trash and found very little information. You do not want to set off any alarms on their network, so you plan on performing passive footprinting against their Web servers. What tool should you use?

Options

  • ADig
  • BPing sweep
  • CNetcraft
  • DNmap

Explanation

Passive footprinting means gathering information about a target without directly interacting with their systems, so no traffic is generated that could trigger IDS/IPS alerts. Netcraft is a web-based reconnaissance service that provides data (web server software, hosting history, OS, uptime) gathered from its own crawls - you query Netcraft, not the target directly. Dig (A), Ping sweep (B), and Nmap (D) all generate direct network traffic to the target, making them active techniques that could be logged and detected.
