The purpose of the IDS (Intrusion Detection System) is to monitor network traffic for suspicious activities and potential threats, alerting administrators when it detects unusual or malicious behavior. The purpose of the IPS (Intrusion Prevention System) is to monitor network traffic for suspicious activities and take immediate action to block or prevent malicious activities from … Read more
Routing protocols can generally be categorized into three types: Distance Vector Routing Protocols: These protocols determine the best path to a destination network based on distance or hop count. Examples include Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP). Link-State Routing Protocols: These protocols build a detailed map of the network topology by … Read more
SCTP (Stream Control Transmission Protocol) operates by providing reliable, message-oriented transport services between two endpoints in a network. Here’s how SCTP works: SCTP establishes and maintains associations between endpoints, similar to TCP connections. It supports both unicast and multicast communication. SCTP segments data into messages, each with its own sequence number for tracking and reordering … Read more
NFS (Network File System) is commonly used for sharing files and directories between Unix-like systems over a network. It allows remote systems to access files stored on a server as if they were local, facilitating centralized storage and collaboration among users and applications. NFS is particularly useful in environments where multiple clients need to access … Read more
Stream Control Transmission Protocol (SCTP) is a transport layer protocol designed to provide reliable, message-oriented communication between two endpoints in a network. SCTP offers features similar to both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), but with enhancements tailored for specific applications and network environments. The Stream Control Transmission Protocol (SCTP) is a … Read more
A network-based file system is a storage system that enables files and directories to be accessed over a network by multiple clients. It allows users and applications to store, retrieve, and manage data as if it were stored locally, regardless of the physical location of the storage devices. Network-based file systems provide a centralized approach … Read more
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols used to secure communication over a computer network, typically between a client (like a web browser) and a server (like a web server). Here’s how they differ: SSL was the predecessor to TLS, initially developed by Netscape in the early 1990s. It provided … Read more
The Session Initiation Protocol (SIP) is a signaling protocol widely used for initiating, maintaining, and terminating communication sessions over IP networks. It is commonly used for voice and video calls, instant messaging, multimedia conferences, and other real-time communication applications. SIP operates independently of the underlying transport layer protocol and is designed to be flexible and … Read more
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
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
