DNS Under Siege: Ethical DNS Spoofing and Countermeasures

The Domain Name System (DNS) is a crucial part of the internet, responsible for converting human-readable domain names into numerical IP addresses that computers use to communicate. However, DNS is vulnerable to spoofing attacks, where attackers manipulate DNS responses to redirect users to fake websites. These attacks can lead to data theft, phishing, malware infections, and unauthorized access to sensitive information. Despite existing security measures, DNS spoofing remains a serious cybersecurity threat due to weaknesses in the traditional DNS protocol. The implementation of this framework is detailed step by step, including the use of tools such as tcpdump, Wireshark, Zeek, Suricata, Scapy, and Ettercap for monitoring and testing. The proposed system is evaluated based on key security metrics, including the attack success rate, anomaly detection accuracy, and performance impact. Our results show that this framework significantly reduces the success rate of DNS spoofing attacks by 90%, achieves 95% accuracy in detecting threats, and maintains a minimal increase in DNS resolution time.
