10 Best DNS Monitoring Tools in 2022
How does DNS monitoring work?
DNS monitoring is essential for ensuring the security of communication between clients and web services. Monitoring itself is based upon consistent and periodic verification of DNS records for any extraordinary changes or localized outages.
This allows you to pinpoint and eliminate any potential issues that might impact your website's function and the security of both your and your client's data.
DNS is a possible way for attackers trying to penetrate your defense, and they try to do so by:
- Cache Poisoning - inserting own false information into DNS cache. This usually reroutes users to a fraudulent copy of your website and steals their private and often sensitive data, such as credit card information.
- DDoS and DoS - Distributed Denial of Service and Denial of Service depends on either single or multiple computers attempting to crash your website with an overload of requests.
- Tunneling - DNS servers handle vast amounts of traffic, which prevents most security software from monitoring all the exchanged data packets. However, monitoring traffic on the server can help to detect chunks of traffic to a previously unknown server or a large number of long requests and responses, this is called tunneling, and DNS monitoring can help to stop it.
Impreva analyses even more approaches to DNS Hijacking, if you want to learm more about the threats your DNS faces, make sure to check it out.
What could happen if your DNS gets breached?
Every breach represents a problem that can range from a minor dysfunction to a catastrophic failure. The wrong configuration can prevent users from accessing your site and drive potential customers away from you.
DNS spoofing or cache poisoning can compromise users' data and destroy the reliability of your name, and DDoS, DoS, or tunneling can cause a possible leak of sensitive information and open your business to the vulnerability of potential blackmail or drive your customers into various hacking, or phishing schemes.
DNS breaches have serious implications - that's why you need to prevent them.
Benefits of DNS monitoring
- Increased security of communication
- Fast detection of any service outages or protocol failures
- Boosted application, services, and server availability and effectivity
