It’s a common misconception that distributed denial of service (DDoS) is all about the very large attacks. The highest volume attacks certainly make all the headlines, but they are actually a tiny minority of the overall DDoS threat. The fact is that small DDoS attacks are an everyday occurrence for many organizations. Corero research indicates a significantly growing number of short-duration, low-volume attacks affecting organizations’ networks.
Smaller DDoS attacks can be just as sinister as the highest-volume ones, for three reasons:
- They consume resources, which impacts the overall experience for end-users
- They consume IT security staff time for troubleshooting
- They can serve as a vector in sophisticated cyber-crime reconnaissance activities
The impact of smaller attacks
How do smaller attacks cause damage? They can overwhelm infrastructure and security devices, and chip away at host resources, thus denying end-users access to Internet-facing applications. Web-site, application and service availability are crucial to ensuring customer satisfaction and sustaining customer trust and confidence in a brand. Even a few minutes of downtime or latency can hurt a company’s bottom line, erode customer confidence, and tarnish overall reputation.
Attackers favor small DDoS attacks because they require much less effort, use fewer resources, and can often escape the radar of legacy, detect and redirect, and homegrown DDoS mitigation tools, which struggle to distinguish them from regular traffic. Such attacks can also enable attackers to survey and ‘pressure test’ a network for its vulnerabilities, so that the next time they launch an attack they can capitalize on that insight and perfect their techniques to wreak greater damage.
Organizations' awareness of DDoS attacks
Organizations should be wary of being quick to claim that their business systems have not been affected by a DDoS attack, because this is extremely difficult to ascertain, unless they have the visibility and mitigation provided by granular, real-time DDoS protection systems. Organizations that don’t have the right protection in place could unknowingly suffer service impact, as well as outages that they might attribute to other IT issues, due to the lack of visibility. No website or online application is immune to DDoS, and any size DDoS attack is cause for concern.
