DNS cache – Definition

Definition of DNS cache

DNS cache is a temporary cache memory that DNS resolvers and other devices utilize to store information. The memory stores the DNS records that were first applied to the searched domain names. The IP addresses (IPv4 or IPv6) of domain names, information about their email server, their services, authentication and verification data, and more are all stored in these records. All of the data will be saved in the DNS cache. However, as previously stated, it will only be for a short time, as determined by the TTL (Time to Live) value issued to each DNS record.

Load balancing – Great solution for mitigating all risks

Our topic today is Load balancing. If you want to learn about its primary purpose, how it works, and why it mitigates all the risks, you are in the right place. So, let us begin by discussing the meaning of Load balancing.

What is Load balancing?

Load balancing in DNS is a method of distributing client requests across server computers by using domain setup. For example, the domain name might be associated with a website, email system, or any other Internet-based service.

What is a Teardrop attack and how can it affect you?

A Teardrop attack is a type of Denial-of-Service attack in which the criminal delivers large volumes of malware data to the targeted machine, causing it to fall. Let’s plumb its depths and explain more.

Teardrop attack – detailed explanation

One of the most common DoS (Denial-of-Service) attacks is the Teardrop attack. Its goal is to inundate its target with malicious fragmented data packets that the victim will be unable to reconstruct and, as a result, will be unable to operate. This exploit takes advantage of a unique flaw in the TCP/IP reassembly procedure. As a result, the fragmented data packets exceed the victim’s capacity until it crashes while attempting to process them.

What is DNS spoofing and how to protect yourself?

What does DNS spoofing mean?

DNS spoofing is a form of cybercrime. Criminals insert spoofed or stolen DNS records into a recursive server’s cache. This is due to answering DNS users’ queries with a falsified record, such as a forged IP address. Legitimate traffic is therefore fraudulently redirected to dangerous places (generated websites). Once there, consumers may be compelled to enter sensitive information (passwords, bank credit card details, etc.) for hackers to exploit later.

Basic knowledge of DNS

DNS is a fundamental element of the Internet that has an essential purpose. This infrastructure makes the usage of the Internet for humans simple and easy. So, let’s explain a little bit more about it!

DNS explained

The Domain Name System (DNS) holds an extensive database with all actual domain names and the IP addresses that correspond to them.
