The National Cyber Security Centre has created two factsheets to assist organisations in their response to Distributed Denial-of-Service ((D)DoS) attacks.
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 to take both technical and organisational measures to protect your organisation against the various forms of (D)DoS attack. Make an overview of your ICT infrastructure. Take technical measures to protect in-house components. For external components, make arrangements with the relevant supplier. Prepare your organisation for an attack by creating a clear response and communication strategy.
The NCSC has created two factsheets to assist your organization in this endeavor:
Continuity of online services (update) and Technical measures for the continuity of online services (new).
