On 7 September 2019, Wikipedia suffered a suspected DoS attack that resulted in intermittent site access for some users in the UK, Europe and the Middle East.

The NCSC explains that when a website suffers a DoS attack, it will appear to users that the site has simply stopped displaying content. However, for businesses it could mean that the online systems they depend upon have ceased to respond.

The collection of guidance published by the NCSC helps organisations mitigate against DoS attacks and outlines the importance of understanding your service, creating a response plan, scaling and monitoring.

There is also guidance around the very minimal DoS response plan any organisation should have in place. To access the NCSC guidance, click here.
