What is the purpose of TCP?

In the digital age, where global communication is essential, the Transmission Control Protocol (TCP) plays a crucial role in ensuring seamless data transmission over the Internet. It is a foundational protocol that forms the backbone of modern networking, enabling devices across the world to exchange information reliably, efficiently, and securely. So, let’s break down its inner workings, significance, and impact on our daily online experiences.

The Basics of TCP

TCP (Transmission Control Protocol) is one of the core protocols of the Internet Protocol Suite (TCP/IP), which controls how data packets are transmitted and received across networks. It operates at the transport layer of the OSI model and provides a reliable, connection-oriented communication mechanism. Unlike its counterpart, the User Datagram Protocol (UDP), which offers minimal error-checking and no guaranteed delivery, TCP focuses on ensuring that data is delivered accurately and in the correct order.

Get familiar with Authoritative DNS server

In the labyrinthine structure of the internet, where billions of devices communicate seamlessly, the Domain Name System (DNS) stands as a crucial pillar. While everyone appreciates the ease of typing a friendly website name like “example.com” instead of a numeric IP address, it’s the DNS that makes this user-friendly translation possible. Central to the DNS process is the Authoritative DNS Server. Let’s delve into understanding this essential entity.

What is a DNS Server?

Before diving into the concept of an Authoritative DNS server, it’s vital to understand what a DNS server does. In its simplest form, a DNS server translates human-friendly domain names into IP addresses, ensuring that internet users reach the correct online destinations.

DNS Spoofing: Is it really dangerous?

In today’s digitally interconnected world, the Domain Name System (DNS) plays a crucial role in translating human-readable domain names into their corresponding IP addresses. However, like any technology, DNS is not immune to security vulnerabilities. One such threat is DNS spoofing, a malicious practice that can lead to serious consequences for users and organizations alike. In this blog post, we will explore the concept of DNS spoofing and examine whether it is truly as dangerous as it is often perceived.

Understanding DNS Spoofing

DNS spoofing, also known as DNS cache poisoning, is a technique employed by attackers to manipulate the DNS resolution process. The objective is to redirect users to fraudulent or malicious websites by altering the DNS cache entries on a targeted DNS server. This can be achieved by injecting false DNS responses, causing the server to associate incorrect IP addresses with legitimate domain names.

DoS attack vs DDoS attack: What is the difference?

DoS attack vs DDoS attack – what is its main comparison? We will explore this today!

What is a DoS attack?

Dos is short of a Denial of Service attack. In this attack, a single attacker targets a device, trying to make it unavailable to its users. It does it by flooding it with traffic or exploiting vulnerabilities of a network protocol.

While DoS attacks are smaller than DDoS attacks, they can still have significant impacts on the availability and performance of a victim’s device. They can slow down, crash, and disrupt the normal processes of a server.

DNSSEC explained for beginners

Introduce to DNSSEC

In order to supply cryptographic authentication to DNS data, a set of security techniques known as DNSSEC (Domain Name System Security Extensions) was built. It verifies and validates the accuracy of DNS data, so you know they haven’t been changed.

Because it validates each DNS query step, network experts frequently refer to it as a chain of trust.

Complete breakdown of DNS outage

A DNS outage can be a nightmare. Your finance team will be very nervous about calculating the losses. Marketing will struggle if a special sale or campaign is running. IT experts will be under severe pressure trying to solve it. And users will be disappointed.

What is a DNS outage?

A Domain Name System outage is a period during which the Domain Name System does not respond. To be reachable through the Internet requires DNS. Without DNS resolution or Recursive servers search, your online business will remain unavailable.

Private DNS server: Definition & Benefits

You’re looking up what a Private DNS server is on the internet? If so, you’ve come to the right place. This article will look at its primary function, why it is so essential to implement, and how you can use it on your device. So, let us begin this adventure.

Private DNS server: Definition

As the name may suggest you, a Private DNS server seems to be something personal. It functions as the interaction between your network and the Domain Name System server, preventing third parties data from being intercepted. They’re DNS networks that aren’t connected to the Public DNS. Consider it a personal library with a select group of books. This has both downsides and benefits. Yes, you will not be able to read a particular genre of book. However, there is one advantage: no one will know what you are reading because your library is private.

Botnet attack explained in detail

The Botnet attack is a real and dangerous threat you should be aware of.

What is a Botnet attack?

A Botnet attack is a type of cyber attack executed through a bunch of infected devices connected to the Internet and commanded remotely by an attacker. Botnet means robot network. Such networks can include mobile phones, computers, and all types of IoT devices. Criminals control them with a specific target (victim) and objective.

How does the Botnet attack work?

What is DNS tunneling?

Do you know how dangerous and damaging DNS tunneling could be for your organization? If not, no worries. In this article, we will explain that. In addition, we will give you more information about its purpose, how it functions, and the prevention methods. So, let’s not waste any more time and get into business.

Meaning of DNS tunneling

DNS tunneling is a malicious and complex attack. Its purpose is to send DNS requests to the attacker’s server, giving the attackers a covert conduit for command and control and a route for data espionage. The cybercriminals breach the target DNS server and remotely take over management using data payloads.
