Introduction to Ethical Hacking
Footprinting and reconnaissance are the initial phases of ethical hacking that involve gathering information about the target system.
The first step in footprinting is to gather information about the target system. This information can be obtained from publicly available sources such as social media, company websites, and search engines. Hackers can also use tools such as whois to obtain information about the domain registration, IP addresses, and contact details of the target system.
The next step in footprinting is to scan the target system for open ports and services. Hackers use tools such as Nmap to scan the target system for open ports and services. Once the open ports and services are identified, hackers can use tools such as Banner Grabbing to obtain information about the version and type of the service running on the open port.
Reconnaissance involves actively searching for vulnerabilities in the target system. Hackers can use tools such as Google Hacking to search for vulnerabilities in the target system. Google Hacking involves using specific search terms to search for vulnerabilities in the target system. Hackers can also use tools such as Shodan to search for vulnerable systems on the internet.
In conclusion, footprinting and reconnaissance are the initial phases of ethical hacking that involve gathering information about the target system. Hackers use various tools and techniques to collect information about the target system, including publicly available sources and specialized tools. Once the information is collected, hackers can use it to identify vulnerabilities and plan their attack.
