As most technological solutions were not designed with security in mind, the DNS protocol is no exception. Modern cyber threat landscape where attack techniques have increased in sophistication and are continuously evolving, the traditional cybersecurity controls in the post-pandemic era are no longer relevant with working habits changing and the need for organizations to secure users and endpoints across other locations; infrastructure that is hosted on-premises and multi-cloud environment.
DNS infrastructure are critical assets for all organizations, whether it is an enterprise or an internet or cloud service provider. Protecting DNS infrastructure from cyber-attacks is a critical activity for security professionals. Any compromise of the DNS infrastructure can result in significant ramifications. A compromise of a DNS server may result in destructive consequences both for remote and corporate users.
DNS attacks vary in complexity and nature – the context of this article is focused on the importance of DNS security for users and endpoints in the post-pandemic era where they may work from the office or remotely.
Cybercriminals have been consistently taking advantage due to mismanagement of DNS security controls within organizations to exfiltrate data out of the organization from infected endpoints and perform redirects to malicious phishing sites. DNS security is important to identify risky or dangerous domains and preventing users from connecting to them, preventing users from connecting to non-sanctioned domains where the risk of data loss is higher and identify anomalous DNS-layer activity that can indicate an infection or malicious activity.
