Domain Name System Security Extensions (DNSSEC) is a security system that helps verify the origin and integrity of data moving back and forth in a DNS resolution process. It is recommended as the best solution for preventing DNS poisoning attacks.
DNS poisoning or spoofing is done when an attacker intercepts a DNS request and sends a fabricated (poisoned) response to the client.
Need to protect your organization against DNS poisoning? Validate your DNS requests for better security with DNSFilter.
DNSSEC prevents attackers from manipulating or poisoning the responses to DNS requests.
This is done by adding cryptographic signatures to domain name records. These signatures are then used to verify that the request for a DNS record comes from its authoritative name server and wasn’t spoofed or manipulated in the request process, or a fake record injected in a man-in-the-middle attack.
With DNSSEC, every DNS request is signed and verified to protect you from exploitation.
Taking advantage of the protective benefits of DNSSEC is easy and straightforward with DNSFilter.
DNSSEC often gets a bad reputation in the DNS security space with reports of it being slow, unencrypted, and prone to outages. But many of the outages attributed to DNSSEC have nothing to do with DNSSEC or are caused by avoidable DNSSEC misconfigurations.
At DNSFilter, we have eliminated these DNSSEC misconfiguration issues by abstracting all the configuration overhead and providing a layer of DNSSEC that you can trust.
All you need to do is point to our DNS resolvers that are equipped with DNSSEC validation and you have all the benefits of DNSSEC on your network
