Factsheet Technical measures for the continuity of online services

During a Distributed Denial-of-Service ((D)DoS) attack, online services or the supporting infrastructure is overburdened or overloaded with network traffic. These attacks can disrupt your organisation’s ICT and, in turn, any dependent business activities. This can lead to (reputation) damage. (D)DoS attacks constitute a real threat to organisations that provide online services, such as websites.

The NCSC advises taking multiple technical measures to protect your infrastructure against the various forms of (D)DoS attack. Use risk management and technical analysis to determine which measures apply to your particular organisation. The NCSC has published this factsheet and updated the factsheet Continuity of online services to support your organisation in this task.
