What is Cache Poisoning? | UpGuard

https://www.upguard.com/blog/network-security is of the utmost importance when it comes to protecting servers. One of the most common yet often undetectable ways the security of your servers can be compromised is cache poisoning.

This is because the DNS (Domain Name Server) resolver can respond to queries without having to communicate with multiple servers.

Since cache poisoning can be hard to detect, prevention is the key to protecting your servers.

UpGuard can help prevent DNS cache poisoning attacks by identifying vulnerabilities, such as DNS issues, that could facilitate cyber attacks that lead to costly data breaches.
