Introduction One of the fundamental building blocks of the internet is the Domain Name System (DNS), which plays a critical role in simplifying our access to websites. DNS translates domain names into IP addresses, facilitating communication between humans and computers. This technology, which we use daily, ensures seamless browsing on the internet. In this article, we will explore what DNS lookup is, how it works, and
Introduction In today’s rapidly advancing digital world, networks are the backbone of communication, data transfer, and resource sharing. Whether it’s connecting people through social media, enabling global business operations, or simply allowing us to browse the internet, networks are integral to modern life. This article will delve into the concept of networks, exploring what they are, how they function, the different types, and the crucial role of
Introduction Network security is one of the most critical aspects of modern information technology. One of the key responsibilities of a network administrator or cybersecurity professional is to ensure the security of devices on the network. However, to achieve this, it’s crucial first to understand the operating systems of the devices within the network. Knowing the operating systems helps in
Introduction In today’s networked world, securing DNS traffic is crucial. DNS, being one of the core protocols of the internet, is often targeted by attackers for DDoS and DoS attacks. Monitoring DNS traffic for unusually large packets can help in detecting these attacks early. This article walks you through creating a Python-based tool using pyshark and colorama to monitor DNS traffic and alert you to
Introduction Network security is one of the most critical priorities in the digital world. Ensuring network security involves not only protecting against external attacks but also detecting suspicious activities occurring internally. Effective network traffic monitoring and SSH tunneling detection are crucial in achieving this. Techniques like tunneling can be used to bypass security measures or leak data. In
Introduction In the modern world, computer networks have become an integral part of our daily lives. We use networks to connect to the internet, share data, and communicate. In this article, we will explore the fundamental concepts of computer networks and the steps to gain proficiency in this field. Learning Objectives After reading this article,
Introduction In today’s interconnected world, safeguarding digital assets has become a priority for businesses and individuals alike. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are critical components in a robust cybersecurity framework, designed to protect against ever-evolving cyber threats. Cyber attacks and data breaches can result in significant financial losses, operational disruptions, and damage to an organization’s reputation. Therefore, implementing IDS and IPS systems is
Introduction: In today’s world, technology is evolving rapidly, and devices connected to the internet are becoming an integral part of our lives. In this context, network security and privacy are gaining importance. MAC (Media Access Control) addresses are unique identifiers used to identify your network devices. However, sometimes you may need to change these MAC
Introduction: In our daily internet usage, security is of paramount importance when communicating online. Especially when exchanging data between websites, it is crucial to ensure that our information is secure. One way to achieve this security is by using SSL (Secure Sockets Layer) certificates. In this article, we will explore what SSL certificates are, why
Introduction Discovering devices on a network is a critical task for network administrators and security experts. In this article, we will learn how to perform ARP (Address Resolution Protocol) discovery using the Python Scapy library and explore how we can use it to find devices on the network. Learning Objectives A Brief Introduction to ARP
