Our Internet world would collapse without the DNS protocol. Known as one of the oldest protocols, the DNS protocol would bring networks to a halt if it were to malfunction. Unfortunately, it has become a target for hackers. Read this article to find out what kind of attacks the protocol is under.
DNS tunneling: what is it ?
The DNS protocol is likened to the role that a phone book plays. You will only need to know the name associated with your domain to successfully access your website. This misuse of the protocol is called the "DNS tunnel". For more details, click on the following link https://www.factsyoumustknow.com/. Indeed, the DNS protocol is an "open source" and this is its major flaw. So, hackers, through a tunnel they create, access websites with bad intentions. In most cases, these hackers exfiltrate sensitive data and information for malicious purposes.
Furthermore, it should be noted that this action, DNS tunneling, is damaging and creates great damage for companies that have suffered this attack. These damages include loss of revenue, deterioration of the company's image, customer defection, among others.
The measures against DNS tunneling
Today, it is still difficult to tell the difference between a legal DNS request and a DNS tunnel. However, this threat continues to be the subject of notorious neglect. So, security solutions must be found to ensure an optimal experience on the networks. For example, this security measure must include a tool that can identify data exfiltration attacks and prevent them. Likewise, the new tool must create a sort of blacklist where the destinations of the stolen data will be recorded to prevent future attacks.
In addition, a real-time network traffic monitoring tool is needed. This will allow a deep analysis of various DNS requests in order to detect probable anomalies.
