What is the transport layer security session?

A Transport Layer Security (TLS) session refers to a secure communication session established between a client and a server using the TLS protocol. It encompasses the entire process from the initial handshake, where the client and server negotiate security parameters, to the secure exchange of data using encryption algorithms agreed upon during the handshake. A … Read more

What is the purpose of IGMP?

The purpose of IGMP (Internet Group Management Protocol) is to manage and control IP multicast group membership within a network. It allows hosts to inform multicast routers about their interest in receiving multicast traffic for specific multicast groups. IGMP ensures efficient delivery of multicast packets by enabling routers to forward multicast traffic only to those … Read more

What is a Secure Shell used for?

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

What is CDP and LLDP?

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

What is the UDP protocol for remote desktop?

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

What are the benefits of LLDP?

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

What is the difference between RDP and VPN?

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

What is the purpose of the intrusion system?

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

How does the link layer discovery protocol work?

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

What is the NIC portal?

The NIC portal refers to the online platform provided by the National Informatics Centre (NIC) that offers various digital services, information, and resources to government departments, citizens, and businesses in India. The work of NIC includes developing and managing IT infrastructure, providing e-governance solutions, and offering consultancy services to government organizations. NIC supports the implementation … Read more
