Securing the DNS layer to increase resilience
Internet security is an increasing concern for businesses, and while IT software and applications can be protected by antivirus software and endpoint security software solutions, DNS protection requires a different approach.
The role of foundational technologies like DNS, DHCP and IP Address Management (DDI)—when modernised by specialist providers to support cloud and hybrid deployments—is essential in delivering secure and resilient infrastructure, now more than ever.

If malicious actors take control of DNS infrastructure, an organisation’s applications can disappear from the Internet, or domain names can be hijacked for disruption, manipulation or phishing attempts.
Securing the DNS servers from increasingly sophisticated attacks is essential to protecting revenue, users and brand reputation. Fortunately, a basic, layered approach can dramatically reduce the impact of DNS-related attacks, and better position organisations to withstand the impact of downtime whilst increasing
