WPA3 (Wi-Fi Protected Access 3) enhances Wi-Fi security by implementing several key improvements over its predecessor, WPA2. It introduces stronger encryption protocols, such as the Simultaneous Authentication of Equals (SAE) protocol, also known as Dragonfly, which replaces the Pre-Shared Key (PSK) method used in WPA2. SAE strengthens protection against offline dictionary attacks and ensures more … Read more
EIGRP, or Enhanced Interior Gateway Routing Protocol, utilizes the DUAL (Diffusing Update Algorithm) algorithm to achieve efficient routing in computer networks. DUAL is responsible for calculating the shortest path to each destination network based on metrics like bandwidth and delay. It maintains loop-free routing by quickly reacting to network topology changes and computing alternative routes … Read more
WPA2 (Wi-Fi Protected Access 2) is a security protocol designed to secure wireless networks. It operates by encrypting data transmitted over the Wi-Fi network to prevent unauthorized access and eavesdropping. WPA2 uses the Advanced Encryption Standard (AES) algorithm with a 128-bit key for encryption, which is considered highly secure and suitable for protecting sensitive information … Read more
OSPF areas function as logical groupings within an OSPF autonomous system (AS), allowing network administrators to segment large networks into smaller, more manageable units. Each OSPF area maintains its own link-state database (LSDB) and routing table, significantly reducing the complexity of routing computations and the size of routing updates. OSPF routers within the same area … Read more
The purpose of an Ethernet is to provide a reliable and standardized method for connecting devices within a local area network (LAN). Ethernet technology facilitates the transmission of data packets between computers, printers, routers, and other networked devices using a wired connection. It supports high-speed data transfer rates, network reliability, and scalability, making it suitable … Read more
Bluetooth in Android devices operates by establishing a wireless connection between two devices using radio waves in the 2.4 GHz frequency band. It enables data exchange over short distances, typically up to 10 meters, without requiring a physical connection. Android devices use Bluetooth to connect and communicate with other Bluetooth-enabled devices such as headphones, speakers, … Read more
MPLS (Multiprotocol Label Switching) is a protocol used in telecommunications and computer networks to speed up and shape network traffic flows. Its primary function is to direct data packets along predetermined paths through the network. MPLS operates at Layer 2.5, between traditional Layer 2 (Data Link) and Layer 3 (Network) of the OSI model. This … Read more
The need for TLS (Transport Layer Security) arises from the necessity to secure data transmitted over the internet against unauthorized access and interception. TLS encrypts data exchanged between devices, such as web browsers and servers, ensuring confidentiality and integrity during transmission. It protects sensitive information, such as login credentials, financial details, and personal data, from … Read more
OpenSSH serves the purpose of providing secure encrypted communication between two computers over an insecure network. It implements the SSH (Secure Shell) protocol suite, offering encrypted authentication and secure data transmission, which helps protect sensitive information from eavesdropping, tampering, and unauthorized access. OpenSSH is widely used for remote login, file transfer, and tunneling services, making … Read more
The purpose of TLS (Transport Layer Security) is to provide secure communication over computer networks, ensuring data confidentiality, integrity, and authentication between clients (such as web browsers) and servers (web servers, email servers, etc.). TLS encrypts data transmitted over the internet, preventing unauthorized access and interception by encrypting data packets exchanged between communicating applications. It … Read more
