Footprinting and Reconnaissance
Footprinting and Reconnaissance is the first phase of a Penetration Testing process, where a penetration tester (pentester) gathers information about the target system, organization or infrastructure. This can include network topology, domain details, email addresses, IP addresses, open ports, and other details that can assist in identifying potential entry points. This phase involves the use of various tools, techniques, and methods to gain information about the target system, such as passive reconnaissance, active reconnaissance, and social engineering attempts. The information gathered during this phase is vital in planning necessary attack strategies, identifying potential vulnerabilities, and understanding the attack surface.
Guide to Footprinting and Reconnaissance For CompTIA Security+
What it is: Footprinting and reconnaissance refer to the initial steps in ethical hacking or penetration testing, where a hacker collects information about the target. This might include details about domain name, IP address, network topology, and other valuable data that can be used to exploit vulnerabilities.
Why it is Important: Footprinting and reconnaissance are important because they provide a map of the target system/network. This data can then be used to reveal potential vulnerabilities that a malicious party may exploit. Without understanding the network's architecture fully, a penetration tester might miss critical vulnerabilities.
How it Works: The process can be broken down into several steps: Public Data Harvesting (collecting info about the target from public sources), Whois Lookup (gathering data about the person/organization the domain is registered to), Network Enumeration (identifying the domains and its associated networks), and Scanning (scanning the network to identify active IP addresses and ports).
Exam Tips: Answering Questions on Footprinting and Reconnaissance: When answering exam questions on this topic, always remember that the primary purpose of footprinting and reconnaissance is to collect as much information as possible about a target system/network. In questions where you're asked to identify the correct order of steps, keep in mind that it usually starts with passive methods (like public data harvesting) and gradually becomes more active (like network scanning).
Try to understand how different tools and techniques are used in this phase of penetration testing as exam questions could specify certain tools (like WHOIS, DNS lookup, etc). And lastly, keep privacy and ethical considerations in mind. Reconnaissance should always be legal, ethical, and respect individual's and organization's rights to privacy.
