DNS spoofing – How to protect ourselves?

The Domain Name System (DNS) is vulnerable to threats, and one of the most insidious among them is DNS spoofing. This deceptive technique poses a significant risk to both individuals and organizations, compromising data security and potentially leading to devastating consequences. In this blog post, we will understand its mechanisms, explore its consequences, and, most importantly, learn how to safeguard ourselves against this cyber menace.

What is DNS Spoofing?

DNS spoofing, also known as DNS cache poisoning or DNS poisoning, is a malicious act wherein attackers manipulate the DNS resolution process to redirect legitimate domain name requests to fraudulent IP addresses. This manipulation is achieved by injecting falsified data into the DNS cache of a recursive resolver, leading users to believe they are accessing authentic websites when, in reality, they are redirected to malicious ones.

Is DNS Monitoring an essential part of every security strategy?

What exactly does DNS Monitoring entail?

DNS Monitoring is the automatic examination of the various DNS procedures. An efficient Domain Name System (DNS) Monitoring system will keep you fully informed of all DNS activity, identify faults, and promptly notify you of any security risks. In this manner, the team’s administrator or responsible individual can respond appropriately.

DNS Monitoring uses a variety of tools, methods, and software to keep an eye on your systems and identify problems. You can create your own Domain Name System Monitoring plan or hire a firm to do it for you. There are several vendors offering cutting-edge solutions and assistance to maintain your DNS functioning properly.

DNSSEC: Everything you need to know

The concept of DNSSEC

The collection of security extensions known as DNSSEC gives DNS authentication and data integrity.

The Internet Engineering Task Force (IETF) developed it in the 1990s. Its principal objective is to offer an authentication mechanism that uses digital signatures based on open cryptography to demonstrate the data’s origin. With a private key, the data owner can certify the security of DNS data (DNS records). Each recursive server can authenticate the source of the data by comparing it to the public key.

The root server is at the top of the trust chain, which extends down to the specific hostname. Except for the root zone, which has nothing above it, each zone is signed by the one above it.

The recursive server will drop data and try again if, for any reason, it cannot authenticate it. Be safe rather than sorry.
