Service providers face increasing security and quality of service challenges. Attackers continuously find new ways to leverage social trends to spread malware, and the growing number of Internet of Things (IoT) devices connecting consumers and businesses to everything from home appliances to commercial security cameras is providing new, less secure targets for attackers.
The costs of infected devices and malicious traffic to service providers are multi-dimensional and include increased customer support, reputation damage, capital expenses due to lost bandwidth, and customer churn. Traditional approaches to preventing attacks include endpoint security on devices and web security gateways in networks. But these protections come with a variety of issues and complications.
A different approach is to use the DNS as a security enforcement point – defending with DNS. Every internet transaction is resolved by the DNS. With the right technology, it is possible for service providers to leverage the DNS to block malicious activity and prevent devices on the network from participating in botnets.
