The significance of DNS Monitoring
The DNS Monitoring feature of your network monitoring solution is crucial. It aims to guarantee users’ reliable and secure access to the website or service they are using. DNS Monitoring involves keeping an eye on all Domain Name System (DNS) activity to ensure peak performance.
DNS Monitoring helps identify issues rapidly, identify potential security holes, and thwart malicious attacks. Finding DNS outages and often verifying DNS records for unforeseen changes are required. If a problem is found that can hurt your website or business, it can be fixed right away.
What exactly is the Monitoring service?
Analysts can evaluate if IT equipment is online and functioning as expected while also resolving any issues discovered thanks to a large category of features referred to as Monitoring services. It provides thorough information about the state of your servers, which you use for various applications, including web, email, DNS, and others. As alternatives for Monitoring services, everything from straightforward inspections to more powerful systems that can assess a product’s performance in great detail and even automate repairs when flaws are identified is available.
How does DNS Monitoring function?
With DNS Monitoring, you may choose the type of query on the assigned IP address and launch various DNS queries to a particular domain. The check is announced as DOWN when the result differs from what was anticipated. In this manner, you can quickly ascertain the general state of your DNS servers.
The following are some essentials to be on the lookout for:
- IP address To show the user the correct website, the IP address and the domain name must be appropriately configured. To ensure that the IP address matches the IP address you provided, you can run a DNS query. In this manner, a potential DNS spoofing attack or problem can be promptly found.
- SOA record. Every time your DNS data is modified, a serial number is updated in the SOA (Start of Authority) record. That may help you thwart an impending assault.
- MX record. The MX record manages your incoming email messages. It is essential to keep a watch on it to prevent any email loss, and it may also thwart attacks like message rerouting.
- NS record. Checking your NS (nameserver) records will help ensure that your name server responds to users appropriately.
Conclusion
Now let’s review. As you already know, the DNS determines whether an Internet communication succeeds or fails. DNS Monitoring enables you to protect your online presence by routinely checking your DNS records for any unplanned changes or localized outages brought on by human error or malicious attacks. Unfortunately, staff workers routinely mismanage DNS records and are a favorite target for hackers. In addition to hacking into your ISP account and changing the parameters directly, DNS poisoning and DDoS attacks are the two primary methods that hackers use to bring down a website.
