Distributed Denial of Service attack: Prevention and best practices

Distributed Denial of Service attack: Prevention and best practices


As one of the easiest attacks to launch and often devastatingly effective, a distributed denial of service (DDoS) attack is one of the most common threats in today’s cybersecurity landscape. In simple terms, a DDoS attack seeks to disrupt a target’s connectivity or user services by flooding its network with an overwhelming volume of fraudulent traffic, typically through a botnet.


The damage from a DDoS attack can be devastating. In one recent survey, 98 percent of respondents reported costs of more than $100,000 for each hour of downtime, while over one-third estimated costs in excess of $1 million. The average DDoS attack causes $218,000 in direct damage (around £179,601), in addition to any accompanying extortion, data theft, business disruption, or harm to the victim’s reputation and business and customer relationships. 


Without an effective DDoS attack prevention strategy, complemented with DDoS protection solutions and threat intelligence, organizations are at significant risk. To reduce the risk of a devastating DDoS attack, businesses should adhere to the following five steps as the foundation of an effective DDoS attack prevention strategy:

1. Know What to Watch for


To detect whether a DDoS attack is underway before it’s too late, businesses need to know what normal network traffic looks like. By creating a baseline of usual traffic patterns, they can more easily identify the symptoms of a DDoS attack, such as inexplicably slow network performance, spotty connectivity, intermittent web crashes, unusual traffic sources, or a surge of spam.
