Why is DNS monitoring important?

What does DNS monitoring stand for?

Your network monitoring solution’s DNS monitoring feature is critical. Its goal is to provide users with dependable and secure access to their website or service. DNS monitoring entails keeping track of all Domain Name System (DNS) activity to ensure peak performance.

DNS monitoring aids in the rapid identification of issues, the identification of potential security holes, and the prevention of malicious attacks. It is necessary to locate DNS outages and frequently verify DNS records for unforeseen changes. If a problem that could harm your website or business is discovered, it can be resolved immediately.

Why do you need DNS monitoring?

How does DNS monitoring work?

When performing a health check, an administrator, like other monitoring methods, must keep an eye on many Domain Name System server components. The most basic Domain Name System monitoring system, for example, ensures that the server consistently responds to all Domain Name System requests.

Another method of DNS monitoring is a “basic check,” which involves confirming network access to the specified recursive server. A DNS monitoring system will establish this connection before ensuring that the server correctly resolves the domain name. These checks provide information about DNS health metrics like measured response times and domain name resolution failures.

What should you keep an eye on?

Here are some of the most important things to remember:

  • IP (Internet Protocol) address For the user to see the correct website, the IP address and domain name must be correctly configured. You can use a DNS query to ensure that the IP address you type matches the one you entered. You’ll be able to detect a potential DNS spoofing attack or a mistake much faster this way.
  • MX records. The MX record will control how your incoming email messages are handled. It is essential to monitor it to prevent any email loss and attacks such as communication rerouting.
  • The SOA record. The SOA (Start of Authority) record includes a serial number, which is updated whenever your DNS data changes. This could assist you in repelling an impending attack.
  • NS record. You can check your NS (nameserver) records to ensure your name server responds correctly to users.

Let’s now recap. As you know, communication over the Internet will succeed or fail depending on the DNS. By periodically checking your DNS records for any unexpected changes or local outages caused by human mistakes or malicious attacks, DNS monitoring enables you to safeguard your online presence. Staff members, however, frequently administer DNS records incorrectly and are a preferred target for hackers. DNS poisoning and DDoS attacks are the two main ways hackers employ to bring down a website, breaking into your ISP account and changing the parameters directly.
