📄️ NAT
NAT, or Network Address Translation, rewrites IP addresses and ports as traffic passes through a router or gateway. It is widely used to share public IPv4 addresses across private networks and large subscriber environments.
📄️ NAT logging
NAT logging records Network Address Translation events including IP address mappings, port translations, protocols, and timestamps to support troubleshooting, subscriber attribution, security investigations, and compliance workflows.
📄️ NBAD
Network Behavior Anomaly Detection (NBAD) is a monitoring approach that identifies unusual network activity by learning what normal network behavior looks like and detecting deviations from that behavior.
📄️ NetFlow
NetFlow is a flow-export technology originally developed by Cisco that summarizes IP traffic into flow records and exports telemetry for bandwidth monitoring, traffic analysis, network visibility, and traffic analytics.
📄️ NetFlow Analyzer
A NetFlow Analyzer is a network traffic analysis platform that collects and analyzes flow telemetry such as NetFlow, IPFIX, sFlow, and J-Flow to provide visibility into bandwidth usage, traffic patterns, application activity, and network utilization.
📄️ NetFlow collector
A NetFlow Collector receives, decodes, stores, and analyzes flow telemetry exported by network devices. It provides operational visibility into traffic behavior, bandwidth usage, applications, hosts, and long-term network activity.
📄️ NetFlow sampling
NetFlow sampling selects a subset of packets for flow export instead of processing every packet. It reduces CPU and export overhead while preserving useful visibility into traffic patterns and bandwidth utilization at high speeds.
📄️ Network access
Network access is the ability of a user, device, application, or system to connect to and communicate across a network according to defined authentication, authorization, and policy controls.
📄️ Network Behavior Analysis
Network Behavior Analysis (NBA) analyzes network traffic patterns and telemetry to identify anomalies, suspicious activity, infrastructure issues, and deviations from expected communication behavior.
📄️ Network forensics
Network forensics is the collection, preservation, and analysis of network traffic and telemetry to investigate security incidents, reconstruct historical activity, and support operational or compliance investigations.
📄️ Network monitoring
Network monitoring is the continuous observation of network infrastructure, traffic, and telemetry to maintain operational visibility, detect problems, analyze traffic behavior, and preserve service health.
📄️ Network observability
Network observability is the ability to understand network behavior by collecting, correlating, and analyzing telemetry such as flows, packets, metrics, logs, and contextual data across network environments.
📄️ Network performance
Network performance describes how effectively a network delivers traffic in terms of latency, throughput, packet loss, jitter, utilization, and reliability across applications and services.
📄️ Network performance monitoring
Network performance monitoring measures latency, packet loss, jitter, throughput, and traffic behavior to detect degradation, troubleshoot service issues, and maintain application and network performance.
📄️ Network security monitoring
Network Security Monitoring (NSM) is the collection and analysis of network telemetry to detect threats, investigate suspicious activity, and reconstruct security incidents using flow data, packet capture, and historical traffic analysis.
📄️ Network segmentation
Network segmentation divides networks into controlled trust boundaries to reduce lateral movement, restrict unnecessary communication, improve security visibility, and simplify policy enforcement.
📄️ Network TAP
A network TAP is a hardware device that passively copies traffic from a network link to monitoring systems, enabling packet analysis, troubleshooting, security monitoring, and traffic visibility without interfering with live traffic.
📄️ Network traffic analysis
Network traffic analysis examines packets, flow telemetry, and communication behavior to understand how traffic moves across the network, identify abnormal activity, and improve operational visibility.
📄️ Network troubleshooting
Network troubleshooting is the process of identifying and resolving problems affecting network connectivity, performance, stability, or application communication.
📄️ NGFW
An NGFW, or next-generation firewall, combines traditional stateful inspection with application awareness, intrusion prevention, and advanced traffic inspection to provide deeper security visibility and policy enforcement.
📄️ Node
A node is a physical or virtual system participating in a network analytics deployment. In Trisul Network Analytics, nodes perform roles such as traffic collection, telemetry processing, aggregation, storage, and centralized analysis within distributed deployments.
