Node
Node: Any device that can send, receive, or forward information over the network. This could include computers, printers, switches, or any other device connected to the network. Nodes play an essential role in network infrastructure and the distribution of data, where each one serves as a connection point within the network.
Noise
Noise: In the context of IT and cybersecurity, noise refers to irrelevant or extraneous information or signals that can obscure or interfere with the transmission and processing of data. Digital noise can be caused by electrical interference, signal crosstalk, or data corruption and may result in degraded system performance or errors in data communication.
Network News Transfer Protocol (NNTP)
Network News Transfer Protocol (NNTP): A protocol designed for the distribution, inquiry, retrieval, and posting of news articles or Usenet newsgroups using a TCP/IP network. Primarily used in Internet discussion forums, NNTP provides rules for efficient distribution and updating of articles across a wide network of servers, reducing redundancy and ensuring users have access to […]
Network security
Network security: The set of measures and practices designed to protect a network and the data it carries from unauthorized access, misuse, and destruction. Network security is used to prevent network attacks and protect sensitive information from being stolen or compromised. Examples include firewalls, antivirus software, and encryption.
Network Segmentation
Network Segmentation: Network segmentation involves dividing a larger network into smaller, isolated subnetworks to enhance security, performance, and manageability. By controlling the flow of traffic between segments, organizations can better contain security breaches and reduce the scope of potential attacks. Techniques for network segmentation include the use of VLANs, firewalls, and network access control lists.
Network Sniffer
Network Sniffer: A diagnostic tool that captures, analyzes, and records network traffic, network sniffers can be legitimate tools for network management or malicious means for eavesdropping. By examining data packets, network administrators can identify issues and optimize performance, while malicious actors can potentially capture sensitive information.
