When the Enemy Is DDoS, Holistic Protection Is a Must An infinite variety of attack methods require customizable solutions. By Sean Newman, VP/Product Management, Corero Sun Tzu was an exceptional general, strategist, and philosopher, and certainly one of the most prolific and best-known military figures in history. When he stated that “the greatest victory is that which requires no battle,” it’s safe to assume that he wasn’t anticipating that his words would be relevant many centuries into the future, let alone applied to something as abstract as cybersecurity. But some 2,000 years later, they hold just as true in cyberspace as on the battlefield. While the battles he led centuries ago were complex in their own right, they in no way reached the same orders of magnitude that face today’s enterprises when attempting to secure their organizations. Today, most, if not all, companies do at least a portion of their business online. For many, this means employees rely on cloud-delivered applications to go about their daily tasks, and the companies themselves rely on the internet for their bottom line. It goes without saying that these organizations must be available to their customers 24/7—even brief outages can result in lost revenue and productivity and Cyber Defense eMagazine – November 2023 Edition 96 Copyright © 2023, Cyber Defense Magazine.

do untold damage to a company’s reputation. Gartner estimates that downtime can cost up to $5,600 per minute; meanwhile other estimates suggest that even small businesses may lose over $100,000 per hour. Unfortunately, those daunting figures do more than emphasize the importance of the internet in modern commerce—they put companies squarely in the crosshairs of malicious actors looking to launch distributed denial of service (DDoS) attacks. Modern DDoS attacks pose a triple threat. Nearly 30 years after the first known DDoS attack, whereby a perpetrator floods their victim with traffic from across the internet, it remains a favorite attack type. From the standpoint of a cybercriminal, they have a lot to offer: they can be launched from anywhere in the world; they can be automated and multivector; and increasingly, they can be crafted to behave similarly to “normal” internet traffic, thereby evading human observation and manual, or legacy, mitigation techniques. Best of all, for the attacker perhaps, is the fact that many legacy DDoS mitigation solutions can also take more than ten minutes before their defenses kick in. This has led attackers to engineer shorter, sub-saturating attacks that are capable of inflicting as much, if not more damage, than their larger, longer-running volumetric counterparts. Disconcertingly, malicious attackers have taken a page out of modern warfare and, increasingly, are launching carpet-bomb (also known as “spread spectrum”) DDoS attacks, which distribute themselves across a large number of targets rather than a more easily identifiable single target. This carpet-bomb technique poses a triple threat to defenders in that it’s able to evade detection by flying under the radar of legacy, per-IP analysis techniques and thresholds. This attack technique also invalidates the use of black-hole or null-route mitigation, making it even more difficult for companies to avoid collateral damage. And because they more easily overwhelm scrubbing lane capacity (where traffic is redirected to be cleansed of malicious DDoS packets), cloud service budgets are exceeded and reporting systems are overloaded. Counter the critics. IT security leaders have the unenviable responsibility of selecting exactly the right solutions to defend against a host of ever-evolving threats, and when (not if) an attack occurs, everyone’s an armchair critic. Luckily, there are several basic tenets to follow when selecting the right DDoS defense solution. Less bad isn’t good enough. The best solutions are those that do more than mitigate attacks—they prevent them entirely. Unfortunately, all too many DDoS defense solutions don’t go the extra mile to stave off attacks. Instead, they only make them “less bad” by mitigating them, meaning that organizations must still deal with downtime and lost productivity and/or revenue while they recover. Semantics matter. There is a big difference between “always on” and “on demand.” The former means that your solution is always there, protecting your systems and devices against intrusions.
