DNS Hijacking: Understanding the Threat and Staying One Step Ahead

by RolandJanuary 8, 2024March 20, 2024 No comments

In the ever-evolving landscape of cybersecurity threats, DNS hijacking has emerged as a particularly insidious method used by cybercriminals. It’s a technique that can redirect users from legitimate websites to fraudulent ones without their knowledge. This post aims to shed light on what DNS hijacking is, how it works, its implications, and most importantly, how you can protect yourself from such attacks.

What is DNS Hijacking?

DNS (Domain Name System) is often likened to a phonebook of the internet. It translates domain names that humans can read (like www.example.com) into the IP addresses that computers use. DNS hijacking occurs when this process is manipulated by attackers, leading your requests to a different destination than intended.

What are the consequences of DNS hijacking?

UDP: Definition

What is the UDP goal?

User Datagram Protocol generally refer to as UDP. It is an essential part of the family of Internet protocols. With little latency and loss tolerance, it enables us to connect multiple Internet services.

The delivery of data prior to the recipient’s consent speeds up communication thanks to the User Datagram Protocol. Therefore, User Datagram Protocol is the preferred method for time-sensitive communications like DNS lookups, Voice over IP (VoIP), video, or audio transfers.

Anycast DNS: Definition & Benefits

by RolandJuly 12, 2022November 18, 2022 No comments

You still don’t know what Anycast DNS is? If yes, don’t worry. In this article, we will explain its definition and how it functions. Then, finally, we will see its fundamental benefits. Let’s now explore this exciting topic.

What is Anycast DNS definition?

Anycast DNS is a DNS routing technique that uses several name servers to provide a single IP address. Anycast DNS is designed to distribute nameservers around various regions on the planet and offer users nearby servers. The nameserver with the same IP address nearest to the user when they request a domain will respond to their DNS query. The domain resolution process moves faster thanks to the query’s shorter route, which minimizes latency.

What is TCP/IP and how does it work?

by RolandFebruary 4, 2022January 19, 2023 No comments

TCP/IP is a set of communications protocols that is still relatively unknown. It is a combination of two different components – TCP and IP. This article will look at what it is and how it works.

The definition of TCP/IP

TCP/IP is an abbreviation for Transmission Control Protocol/Internet Protocol. The two protocols (TCP and IP), each with its own set of restrictions, are integrate initially and used for machine communication on networks, including the Internet. It defines how the data travels by determining how it should be split into distinct packets for address, routing, transportation, and delivery.
