DNS monitoring is the topic of our post today. It is critical to know it if you want to improve your security. So, let’s not waste any more time on idle chatter and instead focus on enjoying this adventure.
DNS monitoring – What does it mean?
DNS monitoring is critical for your Monitoring service. Its purpose is to give you a picture of DNS server performance, allowing you to spot server- and client-side DNS issues.
DNS monitoring is extremely useful for quickly identifying problems, detecting potential security breaches, and stopping malicious assaults. It entails checking DNS records on a regular basis for any unexpected changes or localizing DNS outages. That way, if an issue with a detrimental impact on your website or service is discovered, it may be remedied promptly.
What is important to monitor?
Here are some of the most important things to bear in mind:
- IP (Internet Protocol) address. The IP address and the domain name must be appropriately configured in order for the user to see the correct website. You can use a DNS query to verify that the IP address you type matches the one you entered. You’ll be able to see a potential DNS spoofing attack or a mistake much faster this way.
- The SOA record. The SOA (Start of Authority) record contains a serial number that updates whenever your DNS data changes. This could help you fend off an impending attack.
- The MX Record. Your incoming email messages will be managed by the MX record. It is vital to keep an eye on it in order to avoid any email loss, as well as to prevent assaults such as rerouting communications.
- The NS Record. Scanning your NS (nameserver) records will ensure that your name server answers to users correctly.
What DNS monitoring protects against?
DNS monitoring is a significant duty in terms of security, and it has ramifications in other areas. Here are some of the most important things it can protect you from or warn you about:
- DNS outage
Users are unable to access your domain due to DNS disruptions. The DNS outage might last minutes, hours, or even days, and it can have a significant impact on your services. So, DNS Monitoring can assist you in identifying and understanding the source of the problem.
- DNS poisoning
DNS poisoning, also known as DNS spoofing, is a prevalent cyber threat employed by criminals. They inject malicious material into a server’s DNS cache. As a result, consumers are routed to a bogus website, where they typically enter sensitive information such as credit card numbers.
- DDoS and DoS
Other common and deadly cyber dangers include DDoS (Distributed Denial of Service) and DoS (Denial of Service) assaults. A single device (in a DoS attack) or numerous devices (in a DDoS attack) sends massive amounts of bogus traffic toward the victim (server or network). The goal is to overwhelm and bring down the target.
We can infer that DNS Monitoring is a critical component of the Monitoring service. We can safely say that it should be an essential part of any business’ security strategy. It increases the performance and stability of web-based applications in addition to alerting and protecting against attacks.
