Compromising vital infrastructure: communication
Have you ever been witness to a Wi-Fi failure in a household with school-aged children? If so, I don’t have to convince you that communication qualifies as vital infrastructure. For the doubters: when you see people risking their lives in traffic just to check their phone, you’ll understand why most adults consider instant communication to be vital as well. Forms of communication Humanity has come a long way in communication techniques. From drawings on the cave wall to wartime messages sent via courier to the Pony Express and now, the Internet. Modern communication tools enable us to reach most places across the world in a matter of seconds. What are the lines of communications that are more or less vital to our everyday life? The Internet Telephone lines Mobile telephone networks TV and radio broadcasting Granted, if one of these communication forms fails, part of its traffic can be taken over by another form, but they all have their specific pros and cons that make a durational outage hard to cope with. For example, most smartphones are capable of using both the mobile networks and the Internet, but the latter is limited to when they have Wi-Fi access. When cell phone towers go down, as they did during 9/11, users could send messages via Internet messaging services—at that time, AIM, but today WhatsApp, Facebook Messenger, or other platforms. Growing importance In the list I posted earlier, you may have felt that I missed out on letters and postcards, or snail-mail as we often call it. This is because a growing number of companies are keeping us informed through email, their websites, text messages, and other forms of communication that are way faster than postal services. Most companies will still send letters and paper bills if you ask for them, but it’s no longer the default. Our mail delivery services are increasingly starting to resemble package delivery services. They see a growing number of deliveries that require a physical transfer of an object rather than information alone. Instead, the majority of modern communication is digital. Securing digital communication Digital information that needs to be kept from prying eyes and eavesdropping is usually encrypted. To establish secure communication, one may use encrypted mail, crypto-phones, and secure protocols on the Internet. Most of these encryptions are strong enough to withstand brute force attempts at entry—at least for long enough to outlive the usefulness of intercepting the message. Future computer systems like qubit quantum computers, however, may require us to upgrade the encryption strength that we use for these methods. Breaking the Internet Because of the way the Internet has grown and become more versatile, the Internet backbone is robust enough to withstand DDoS attacks of a large magnitude. Yet, there have been instances where an entire country, such as North Korea, was taken offline, or where an attack on a major DNS provider caused a serious disruption in the number of sites we were able to visit. These attacks were targeted at systems that
