Distributed denial-of-service (DDoS) attacks
The goal of a distributed denial-of-service (DDoS) attack is to disrupt service to a network. By overwhelming the targeted machine with a high volume of data or traffic from multiple hijacked computers, a DDoS attack prevents users from accessing emails, websites, online accounts and any other services that rely on the network. While the end targets are often large corporations and governments, anyone’s computer may be commandeered to participate in the attack, often without the user ever knowing. Because the attack is “distributed” among several computers, there is no single source the victim can block to stop it. Defending against both DDoS and single-origin DoS attacks involves sophisticated network protections. Consult your IT vendor for more information.
The methods cybercriminals use to breach your security are varied, and they’re changing every day. A good defense involves following cybersecurity best practices and assessing your organization’s unique vulnerabilities.
