Cybersecurity is built to protect computer systems and networks from attacks such as distributed denial-of-service (DDoS) DDoS attacks work by taking a target website or online service offline by overwhelming the target or its surrounding infrastructure with a flood of internet traffic. Attacks are based on legitimate traffic, and it can be difficult to determine which traffic is legitimate good traffic and which is the bad traffic. All public-facing services are subject to attack and should be tested.”]
