SFTP, or Secure File Transfer Protocol, is a network protocol that provides secure file access, transfer, and management capabilities over SSH (Secure Shell) connections. Unlike FTP, which operates over plain text channels, SFTP encrypts both commands and data using SSH to ensure confidentiality and integrity during file transfers. SFTP works by establishing an SSH session … Read more

A WAN (Wide Area Network) is a telecommunications network that extends over a large geographic area, such as a city, country, or even worldwide. It connects multiple smaller networks, like local area networks (LANs) or metropolitan area networks (MANs), allowing them to communicate and share resources over long distances. A wide area network (WAN) refers … Read more

Intrusion Detection System (IDS) methods of detection primarily involve monitoring network traffic or system activities to identify potential security breaches or malicious activities. One method commonly used by IDS is signature-based detection. This technique involves comparing observed events or patterns in network traffic or system logs against known signatures or patterns of known attacks or … Read more

LAN in Wi-Fi refers to a Local Area Network that utilizes Wi-Fi technology for wireless communication between devices within a limited area, such as a home, office, or public hotspot. In this context, LAN refers to the network of devices connected wirelessly via Wi-Fi access points. The use of LAN in Wi-Fi enables devices like … Read more

ARP command resolves IP addresses to MAC addresses on a local network. ARP is used to establish communication between devices on the same network segment by mapping IP addresses to MAC addresses. You would use the ARP command to troubleshoot network connectivity issues, verify ARP table entries, or clear ARP cache. The “show ARP” command … Read more

ARP, or Address Resolution Protocol, is a network protocol used to map an IP address to a physical MAC address on a local network segment. The purpose of ARP is to facilitate communication between devices within the same network by resolving IP addresses to MAC addresses, which are essential for data transmission at the data … Read more

MPLS, or Multi-Protocol Label Switching, is a networking technology used to efficiently direct data packets along a network using labels. These labels replace traditional IP routing tables, enabling faster and more scalable packet forwarding based on label information rather than IP addresses. MPLS works by assigning labels to data packets at the ingress router when … Read more

Wi-Fi at home refers to the wireless technology that allows devices within a household to connect to a local area network (LAN) without the need for physical cables. It enables devices like smartphones, laptops, tablets, smart TVs, and other smart devices to communicate with each other and access resources such as printers, shared files, and … Read more

SCTP, or Stream Control Transmission Protocol, is a transport layer protocol like TCP, designed for reliable and ordered delivery of data. It supports multiple streams of data within a single connection, providing features like message framing, congestion control, and error detection. Unlike TCP, SCTP can transmit multiple streams of data simultaneously within a single connection, … Read more

An SCTP network refers to a network environment where the Stream Control Transmission Protocol (SCTP) is used as the transport layer protocol. SCTP provides reliable, connection-oriented communication between network endpoints, offering features like multi-streaming, message-oriented data transmission, and support for multi-homing. It is designed to address the limitations of TCP and UDP in scenarios requiring … Read more
