What You and Your DNS Blocking Services Must Do Before And After An Attack

Organizations use several DNS blocking services for various kinds of threats. These DNS blocking services often don’t work together, provide poor ROI, and limit the effectiveness of the security layer. Thus, IT managers search for DNS blocking services that are perfect for their general security architecture.

Cybercriminals always find new approaches to invade networks, with DNS being a standout amongst attack surfaces to exploit. Malicious sites provide a haven for malware and different threats to hide. Malware wait for users to click links in emails or on different sites to get an infection.

Today’s complex threat environment requires DNS blocking services as an add-on to a robust cyber security protection system which is basically, a top-to-bottom defense in cyber strategy. Different safety efforts must work together to protect against a wide range of different attack vectors, including one's organizations might not have considered – for example, those focusing on DNS.

DNS Blocking

If your network has been prepping for the usual DNS security threats, then this guide will help you.

Before an attack happens:

  • Be proactive and know that most security protocols aren’t equipped to manage DNS security. Go beyond the simple attack protection by actively using DNS blocking services to protect DNS packets. Ideally DNS blocking services should be built into the DNS server itself, rather than bolted on to other security technologies.

  • Ensure network visibility by knowing what devices are connected to the network and who is using them. This is essential to DNS blocking services to distinguish and stop a DNS attack. This information allows IT groups to control and mitigate risks to networks from a multitude of devices, without requiring endpoint software.

  • Consider the real-time streaming and analytics done by DNS blocking services to identify threats based on behavioral analysis to pinpoint both known and unknown threats.

  • Protect against a wide range of threats using DNS blocking services both externally and internally by hindering attacks on the DNS framework, disrupting malware, and stopping data exfiltration via DNS.

And if you need to recover from a DNS attack, then read on.

After a threat is identified:

  • React quickly if your organization has visibility into your network. You should be able to quickly discover and react to the risk. IT managers should also have a detailed perspective of attacks, with analytics, enabling them to quickly spot and take action using DNS blocking services to secure their networks.

  • Keep the services and applications up and running even when the network is under attack. Ensure that DNS blocking services allow legitimate traffic through while obstructing illegitimate activity.
