SFTP (Secure File Transfer Protocol) is a network protocol that provides secure file access, transfer, and management capabilities over SSH (Secure Shell) connections. Unlike FTP (File Transfer Protocol), which does not encrypt data by default, SFTP encrypts both commands and data transmitted between a client and server, ensuring confidentiality and data integrity during file transfers. … Read more

A Virtual Private Network (VPN) serves several purposes and offers numerous benefits in today’s digital landscape. Primarily, a VPN is used to create a secure and private connection over a public network, typically the internet. It encrypts the data transmitted between the user’s device (such as a computer or smartphone) and a VPN server, ensuring … Read more

Wireless Fidelity, commonly known as Wi-Fi, refers to a technology that enables wireless networking and internet access in various devices such as computers, smartphones, tablets, and IoT devices. Wi-Fi operates by using radio waves to transmit data between devices within a local area network (LAN), allowing users to connect to the internet or communicate with … Read more

A VLAN (Virtual Local Area Network) is used to logically segment a single physical network into multiple virtual networks. It allows network administrators to group devices logically, regardless of their physical location, into separate broadcast domains. This segmentation enhances network security, efficiency, and management by isolating traffic within specified VLANs and controlling communication between them. … Read more

Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. It operates at the transport layer of the OSI model and ensures privacy, data integrity, and authentication between communicating applications. TLS is commonly used to secure data transmitted over the internet, such as web browsing, email communication, file … Read more

Wireless Fidelity, or Wi-Fi, works by using radio waves to transmit data between devices within a local area network (LAN). Wi-Fi operates on the IEEE 802.11 standards, which define the protocols and specifications for wireless networking. Devices such as computers, smartphones, tablets, and IoT devices connect to Wi-Fi networks by communicating with a wireless access … Read more

WAN (Wide Area Network) area coverage refers to the geographical scope over which a WAN extends. Unlike Local Area Networks (LANs) that cover a limited area such as a single building or campus, WANs span large distances and connect multiple LANs across cities, countries, or even continents. The coverage of a WAN can vary significantly … Read more

Intrusion Detection Systems (IDS) are security tools designed to monitor network traffic or system activities for malicious or suspicious behavior. They analyze incoming and outgoing network packets, system logs, and other data sources to identify potential security threats or unauthorized access attempts. Organizations use IDS to enhance their cybersecurity posture by detecting and responding to … Read more

A NIC (Network Interface Card) is a hardware component that allows computers and other devices to connect to a network. It is typically installed inside a computer and provides the physical interface between the computer and the network medium, such as Ethernet cables or wireless signals. NICs contain a network controller or chipset that manages … Read more

SMB (Server Message Block) authentication works by verifying the identity of users or devices attempting to access shared resources on a network. When a client device requests access to a file, printer, or other shared resource hosted on an SMB server, the server initiates an authentication process. The client sends authentication credentials, typically in the … Read more
