Like most applications and equipment connected to networks, the IoT devices will have unique names to allow them communicate with each other. Generally, it is simpler for human beings to remember names than IPv4 addresses. This future surge in names and DNS dependent applications and services is a pointer to the urgent need for IT administrators and all the stakeholders in the IT world to re-evaluate their DNS security infrastructure in readiness of the coming wave of DNS requests.
IoT is generally vulnerable at the DNS security level. DNS is currently a major target for malicious attacks globally. As the IoT world proliferates, users will need more advanced security mechanisms to protect them against Distributed Denial of Service (DDoS) and cache poisoning attacks. The following are some of the ways that enterprises can look into to secure their IP network infrastructure:
Purpose-Built DNS security
In cases where DNS is the main application layer target, purpose-built DNS security solutions will go a long way in protecting users, data confidentiality and continuity of businesses from IoT threats. Purpose-built DNS security will also create countermeasures for ensuring integrity and continuity of critical services while mitigating the potential risks of false positives.
Real-Time DNS Analytics
Advanced real-time DNS analytics provides essential insights that can be used to detect insider threats to a network such as malware, botnets, and ATPs (Advanced Threat Protection). Such in-depth visibility into DNS security infrastructure enhances breach detection before major damages occur. Attempts to exflitrate DNS transaction data can also be detected and blocked.
When it comes to the security of the Internet of Things, secured and well managed DNS plays a great role in enhancing your security architecture. Enterprises that plan to deploy large scale IoT infrastructure should, therefore, be ready to utilize DNS, DHCP and IP Address Management (or DDI) solutions to ensure that they have full control of their devices , irrespective of their locations or networks that they are connected to.
