As network technology continues to evolve rapidly, traditional hardware-based network management methods have shown limitations in terms of flexibility and scalability. To address these challenges, SDN (Software Defined Networking) was introduced. SDN is a technology that separates the Control Plane from the Data Plane, enabling network administrators to control and manage networks more efficiently. SDN … Read more

TCP Wrapper is an access control utility designed to enhance network security by determining whether a connection request from an external computer should be allowed or denied. It is primarily used in Linux and Unix-based operating systems and enables system administrators to manage network security more precisely. How TCP Wrapper Works TCP Wrapper relies on … Read more

In today’s world, the internet is an essential part of our daily lives, allowing us to work, communicate, and access information from anywhere. However, traditional internet connections often require users to remain in fixed locations, limiting mobility and convenience. To address this issue, WiBro (Wireless Broadband) was developed, offering users high-speed wireless internet even while … Read more

What is WIPI (Wireless Internet Platform for Interoperability)? WIPI (Wireless Internet Platform for Interoperability) is a standard mobile platform developed in South Korea to ensure compatibility between mobile carriers and device manufacturers. Officially introduced in 2001, WIPI provided a unified execution environment that enabled mobile devices to run applications efficiently and ensured consistency across wireless … Read more

Effective scheduling and control are crucial in project management. Particularly in projects where numerous tasks are intricately interwoven, it is essential to accurately determine task durations and their dependencies. One of the most powerful techniques for achieving this goal is the Critical Path Method (CPM). What is CPM? The Critical Path Method (CPM) is an … Read more

The internet exposes users to various security threats, and among them, Spyware and Trojan Horse are some of the most common types of malware. These terms are often confused, but they differ significantly in purpose and operation. This article will compare Spyware and Trojan Horse, explain their infection methods, and provide detailed prevention and response … Read more

Modern security systems heavily rely on encryption techniques to ensure confidentiality and integrity. Among these, the RSA encryption algorithm stands out as one of the most widely used and historically significant public-key cryptographic systems. In this article, we will explore the principles, working mechanism, and applications of RSA in detail. What is RSA Encryption? RSA … Read more

An ARP Redirect attack is a form of ARP Spoofing (also known as ARP Poisoning), where an attacker manipulates a victim’s ARP cache table, tricking them into believing that the attacker is the router. This causes the victim’s network traffic to first pass through the attacker before reaching the actual router. The attacker can then … Read more

ARP Spoofing (Address Resolution Protocol Spoofing) is a type of cyberattack where a malicious actor manipulates MAC addresses within a local network to intercept or modify communications between a client and a server. This article explores the concept, working principle, and effective prevention and mitigation strategies against ARP Spoofing. 1. What is ARP and ARP … Read more

(DoS) attack that exploits a system’s inability to properly handle packets where the source and destination addresses are identical. By crafting malicious packets that have the same source and destination IP address and port number, attackers can cause the target system to enter an infinite loop of responses, leading to resource exhaustion and system disruption. … Read more
