Domain Name System (DNS) is a protocol dictating how computers exchange data on the Internet. It turns a user-friendly domain name into an IP address that computers use to identify each other. DNS protocol is unencrypted by default.
Most security vendors still heavily rely on signature-based detection, such as DNS firewalls and DNS blacklisting. It essentially performs DNS query checks of known bad domains.
In 2-3 years, all DNS traffic will be encrypted. Analyzing DNS traffic will not help to spot and stop malicious activity on the network.
It brings numerous challenges to network operators. They can solve them by implementing security measures powered by Artificial Intelligence.
This white paper discusses why DNS blacklisting is not an effective security control anymore.
With limited IT budgets and lack of security expertise, small businesses are highly vulnerable to today’s cyberthreats. And unfortunately, cybercriminals take advantage of this. The good news, however, is that CSPs are well-positioned to protect their business customers from cyberattacks, by offering cloud-based security-as-a-service.
By leveraging their existing DNS infrastructure, CSPs can offer an in-network security solution that is fully automated and requires minimal hands-on maintenance from SMB end users. The combination of DNS, big data analytics, and data science and machine learning makes for a powerful approach to security services that enables CSPs to grow revenues while maintaining control of their network and online traffic – while generating a fast ROI. Download this paper from Heavy Reading to learn more about how CSPs are utilizing DNS and network infrastructure to stay steps ahead of cybercriminals, keeping their networks and SMB customers protected.
