Q3: How can you define footprinting? What are the different techniques that can be used for it?
Ans-Footprinting is the process by which an ethical hacker gathers more information about a target network without actually interacting with it. This is before he or her actually does a pen test. The same approach is used by an unethical hacker. There are several techniques that can be used to track someone’s footprints.
Network enumeration: Identification and use of domain names and clocks to identify the network clocks.
Open-source footprinting is a technique that allows you to gain the contact information of an administrator. This information would be used to guess your password.
Scanning: Once the hacker has scanned the IT network, he or she attempts to configure any IP addresses that are found on it.
Stack fingerprinting: This is the final step in penetration after scanning has revealed the ports and hosts.
