Secure Shell (SSH) is a cryptographic network protocol that provides secure communication over an unsecured network. It is commonly used for remote login and command-line execution, allowing users to securely access and manage systems and devices remotely. SSH encrypts data exchanged between the client and server, preventing eavesdropping and tampering by malicious parties during transmission. … Read more
CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) are protocols used in networking for device discovery and network topology mapping. CDP and LLDP serve the purpose of enabling devices to discover and learn information about neighboring devices connected directly to them in a network. They facilitate automatic discovery of network neighbors, including device … Read more
Remote Desktop Protocol (RDP) primarily uses TCP (Transmission Control Protocol) for its transport layer protocol, specifically on port 3389. TCP ensures reliable and ordered delivery of data between the RDP client (local machine) and RDP server (remote machine), crucial for maintaining the integrity and responsiveness of remote desktop sessions. UDP (User Datagram Protocol) is not … Read more
LLDP (Link Layer Discovery Protocol) offers several benefits in network management and configuration. It provides automatic discovery of network devices and their capabilities, enabling network administrators to quickly identify and verify the physical connections and configurations within the network. This reduces manual configuration efforts and enhances network visibility, making it easier to manage and troubleshoot … Read more
Remote Desktop Protocol (RDP) and Virtual Private Network (VPN) serve distinct purposes in network communication and remote access: RDP is a protocol that allows a user to remotely access and control a computer or server’s desktop interface over a network. It enables interactive sessions where a user can view and interact with the desktop environment … Read more
The purpose of the intrusion system is to detect unauthorized access or breaches into a network or computer system. It identifies potential threats and attempts to prevent or mitigate damage from malicious activities. The purpose of IDS (Intrusion Detection System) is to monitor network traffic for suspicious activities and alert administrators to potential security breaches. … Read more
The Link Layer Discovery Protocol (LLDP) works by allowing network devices to exchange information about themselves and their connections with neighboring devices. When an LLDP-capable device is powered on or connected to a network, it sends out LLDP Data Units (LLDPDUs) containing information such as device type, capabilities, system name, port ID, and management addresses. … Read more
The intrusion detection system (IDS) is a security technology designed to monitor network and system activities for malicious actions or policy violations. It analyzes traffic patterns, identifies suspicious activities, and generates alerts for administrators to investigate potential security incidents. Intrusion detection system refers to a hardware or software application that automatically monitors events occurring in … Read more
EIGRP (Enhanced Interior Gateway Routing Protocol) is used primarily for routing within enterprise networks. It is designed to provide fast convergence, low overhead, and support for a variety of network topologies. EIGRP is particularly advantageous in large-scale networks where rapid and efficient routing updates are crucial for maintaining network performance and reliability. EIGRP and OSPF … Read more
A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. This ensures privacy and security for data transmitted between the user’s device and the VPN server. Virtual private network refers to a service that allows users to access the internet securely … Read more
