In the era of Internet of Things (IoT) and blockchain, it is a daily nightmare encountered by organizations from both public and private sectors, big and small, struggling to react to the aftermath of the constant cybersecurity breaches and ransomware attacks.
According to the latest 2018 Data Breach Investigations Report by Verizon, there were over 53,000 reported cybersecurity incidents and 2,216 confirmed data breaches in 2017. That is an average of more than six confirmed data breaches per day! The situation can only get worse every year if we do not change our strategy dramatically to efficiently secure and effectively defend the global network infrastructure against all enemies in this new cyberwarfare.
It would be an illusion by now for anyone still to think that we are capable of protecting the security and integrity of the increasingly interconnected global network systems using the Internet Protocol Version 4 (IPv4), which is the current primary version of Internet Protocol (IP) used globally and contributed to almost all of the past and current cybersecurity breaches and ransomware attacks. To a large degree, it is a foregone conclusion that we have already lost the battle against many of the malicious cybercriminals and the state-sponsored actors in the new era of cyberwarfare using IPv4.
However, we may still have a fighting chance to win this cyberwar only if we stop using IPv4 in the current dual stack mode of operation supporting simultaneously both IPv4 and IPv6 (Internet Protocol Version 6). Instead, we adopt the strategy of supporting only one single stack of IPv6 for the Internet. Here is the reason why the mission is still possible by eliminating IPv4 and thus dramatically reducing the overall attack vector in the cyberwarfare:
- The moment we turn off IPv4, we will immediately achieve 100 percent reduction of all current global cyberattacks and cybersecurity threats based on IPv4; we will also immediately achieve more than 50 percent reduction of the overall cyberattacks worldwide based on IPv4 and IPv6 separately and the combination of both stacks.
It is common sense (which is uncommon) that instead of engaging the enemies in two separate battlegrounds concurrently, fighting two separate wars with limited resources, we should utilize all of our global resources and concentrate on fighting, and hopefully winning, only one war! Otherwise, we may potentially lose the fights in both battlegrounds.
This is our best chance to gain the upper hand in this fight. This may be our last chance to protect the security of the next generation of the Internet using the securely deployed single stack of IPv6, which is the only version of IP that is capable of supporting the current and future demand for deploying the emerging technologies, such as Internet of Things. IPv6 is also required for any future innovations that will rely on the support of the Internet.
Cyberwarfare, the mission is possible only if we stop using IPv4, dramatically reduce the current attack vector and focus our limited resources on securing only one single stack of IPv6, fighting only one battle, and winning only one war!
