ADMIN What is IoT? The Internet of Things (IoT) refers to a network of physical and virtual objects that are connected through the internet, exchanging data and creating new value. This technology extends beyond individual devices, enabling objects to interact with each other and operate efficiently without direct human intervention. Core Components of IoT IoT consists … Read more
In today’s world, the connection between objects and information is becoming increasingly important. Among various technologies enabling this connection, Radio Frequency Identification (RFID) stands out as a powerful tool utilized across multiple industries, enhancing efficiency and convenience. This article will explore the fundamental concepts, working principles, applications, advantages, limitations, and future prospects of RFID technology. … Read more
1. Overview of DPI Deep Packet Inspection (DPI) is an advanced network traffic analysis technology that goes beyond basic packet header inspection to examine the actual contents of data packets. Unlike traditional packet filtering, which relies on metadata such as IP addresses and port numbers, DPI inspects packet payloads, allowing for more sophisticated security policies … Read more
Introduction to IPsec Internet Protocol Security (IPsec) is a suite of protocols designed to secure internet communications by authenticating and encrypting each IP packet in a communication session. It was developed by the Internet Engineering Task Force (IETF) to address the inherent security vulnerabilities in the IP protocol. While IPsec was optional in IPv4 and … Read more
TKIP (Temporal Key Integrity Protocol) is an encryption protocol developed to address the vulnerabilities found in WEP (Wired Equivalent Privacy), which was the original security standard for Wi-Fi networks. Introduced as part of the IEEE 802.11i standard in 2003, TKIP was implemented in WPA (Wi-Fi Protected Access) as an interim security solution before the adoption … Read more
In today’s digital world, information security is a crucial aspect of modern computing. Secure encryption techniques are essential for protecting financial transactions, personal data, corporate secrets, and national security interests. To meet these security demands, South Korea developed its own cryptographic algorithm, known as SEED. What is SEED? SEED is a block cipher encryption algorithm … Read more
Introduction The International Data Encryption Algorithm (IDEA) is a symmetric-key block cipher developed in 1991 by James Massey and Xuejia Lai at ETH Zurich, Switzerland. IDEA was designed to replace the Data Encryption Standard (DES), which had become increasingly vulnerable to brute-force attacks due to its 56-bit key length. IDEA introduced a more secure encryption … Read more
In today’s business environment, IT infrastructures must operate 24/7 with high stability. However, server failures can occur unexpectedly, posing a significant risk of service disruptions. To address these challenges, IBM developed HACMP (High Availability Cluster Multi-Processing). This solution enhances server reliability by clustering multiple computer systems to work together efficiently. Concept and Features of HACMP … Read more
What is Tripwire? Tripwire is a host-based intrusion detection system (HIDS) that detects changes in file system objects (files, directories, configuration files, etc.) to identify security threats. It is particularly useful for post-intrusion detection and serves multiple other purposes, including integrity verification, change management, and compliance enforcement. Key Features of Tripwire File Integrity Monitoring: It … Read more
In computer security, a “Worm” is a type of malware similar to a virus, but with a crucial difference. Unlike a virus, a worm does not need to attach itself to another file to spread. Instead, it operates independently, replicating itself and spreading across networks, email systems, and other communication platforms. Key Characteristics of a … Read more
