1. Introduction to Telnet Telnet is a network protocol that allows users to remotely access and manage systems over the internet or a local network. It provides a command-line interface (CLI) for interacting with remote machines, making it useful for system administrators, network engineers, and developers. Telnet operates on port number 23 and was widely … Read more
If you manage a website or frequently transfer files to and from a server, FTP (File Transfer Protocol) is an essential concept to understand. In this guide, we will explore FTP in depth, covering its definition, working principles, usage, security concerns, and alternatives. 1. What is FTP? FTP (File Transfer Protocol) is a standard network … Read more
Cryptographic hash functions are essential for ensuring data integrity and enhancing security. Today, we will explore SNEFRU, a hash algorithm developed by Ralph Merkle in 1989 at IBM. What is SNEFRU? SNEFRU is a cryptographic hash function designed by Merkle that primarily produces 128-bit or 256-bit output values. It was developed with security considerations in … Read more
Cyberattacks exploiting network vulnerabilities have been evolving for decades. Among them, Smurf Attack and Ping of Death (PoD) are two classic ICMP-based attacks that have disrupted systems and networks in the past. Both involve ICMP (Internet Control Message Protocol) but differ in execution and impact. This article will break down the key differences, real-world examples, … Read more
The internet operates by transmitting data in small units called packets. These packets carry information between devices and servers, ensuring seamless communication. Deep Packet Inspection (DPI) is an advanced network management and security technology that goes beyond basic packet inspection by analyzing the actual data within each packet, not just its metadata (such as source … Read more
Introduction to SDN Software-Defined Networking (SDN) is an innovative approach to network management that enables the control and management of network traffic through software rather than relying solely on traditional hardware-based configurations. By decoupling the network’s control plane from the forwarding plane, SDN introduces a more flexible, scalable, and programmable network infrastructure. In traditional networking, … Read more
The Internet Protocol (IP) defines the fundamental rules for transmitting data across networks. The two primary versions in use today are IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). These protocols differ not only in their addressing schemes but also in their data transmission methods. This article provides an in-depth comparison of … Read more
RBAC (Role-Based Access Control) is an access control model that assigns permissions to specific roles rather than individual users. Users are then assigned to roles, which determine their level of access to resources. This approach enhances both security and operational efficiency, making it widely used in organizations and enterprises. Key Concepts of RBAC Role: Represents … Read more
In network security, various attack techniques exist, and among them, Switch Jamming is known as a form of sniffing attack. This attack floods the network with forged MAC addresses, causing the switch’s MAC address table to overflow, rendering it unable to operate normally. In this article, we will explore the concept, working mechanism, attack tools, … Read more
