Plan to be more secure in ’24!
Oct 30, 2023
As much as we anticipate with heightened joy the approaching holiday season, we often anticipate with heightened dread the return from the holidays to a wearisome list of tardy projects, not to mention latent incidents to resolve. Why not start off 2024 with fewer to-dos and incidents by taking steps now to be more Secure in ’24! Our DNS security solutions are simple to deploy and can vastly improve your overall cybersecurity posture.
DNS defense in depth
As DDI events, DNS transactions in particular, may serve as harbingers of nefarious activities, the deployment of DNS security measures can increase visibility and decrease incident detection times. For example, malware that has infiltrated a network device will likely use DNS to locate its command and control (C2) center for software updates, commands or to exfiltrate sensitive data. When applying a defense in depth approach in accordance with acknowledged cybersecurity best practices as outlined in the NIST Cybersecurity Framework (CSF), you can reduce risks to your business and protect your network by protecting your DNS.
For example, implementing a DNS firewall may enable you to detect the initial C2 query and inhibit its successful resolution to stop the malware communication process before it starts. As a secondary layer, DNS tunneling detection and shutdown enables the rapid identification of a data exfiltration attempt and closes the connection to prevent excessive data loss. A third layer may entail the reviewing and investigating of possible network incidents through the analysis of DNS transaction histories from a broad trend level for anomaly detection down to a particular suspicious packet to identify a potential malware source.
DNS security is network security
Applying this multi-layered approach improves your resilience and sharpens your ability to detect and protect against potentially malicious activity within your DNS infrastructure. Cygna Labs offers several DNS security solutions facilitating protections at multiple layers in accordance with the NIST CSF, which can help you bolster your DDI defenses which by definition will bolster your network defenses. And with NIST endeavoring to update the CSF, introducing version 2.0 in early 2024, now is a great time to explore what is coming with the new CSF to help you plan to improve your cybersecurity posture and be more secure in ’24!
