Designing a secure network infrastructure has to go hand-in-hand with network visibility. Attacks are becoming increasingly sophisticated, networking demands are increasing at a rapid rate, and it’s almost impossible to pre...

There was a time when simply deploying network taps in place of SPAN ports put you ahead of the game when in terms of network visibility. In recent years, we’re seeing more and more IT managers shift from single-device network visibility solutions to multi-device, multi-site deployments. However, increasing application demands and the sprawl of net...

Network taps are external appliances that sit between network devices to copy and monitor traffic. Because network connectivity and data security form the backbone of any business, it’s crucial to have pervasive visibility of all traffic. Taps are one of the core network visibility tools that ensure you gain insight from every packet that ...

A leading education and research institution faced security, management, flexibility and robustness challenges pertaining to network visibility. Niagara Networks N2 Network Packet Broker provided a highly configurable and robust, performance-enhancing aggregation point coupled with an enhanced "inline tap" for selective forwarding of traffic to security an...

The network security landscape changes on a daily basis and it is a challenge to know how threats and cyber defenses will evolve every month and year. We have to continually make predictions about the network security changes that are on the horizon. If we don’t, we’ll inevitably fall behind as new threats exploit hidden vulnerabilities and important trends in designing a secure network infrastructure go unad...

The Port Mirroring or SPAN (Switched Port Analyzer) method of monitoring network traffic has been the perennial focus of network visibility. With port mirroring enabled, the switch sends a copy of all network packets seen on one port (or an entire VLAN) to another port, where the packet can be analyzed. As a SPAN port is unidirectional and network traffic is bidirectional, the aggregate traffic could be twice as mu...

A Technical Overview and Deployment Considerations The IPFIX (IP Flow Information Export) protocol was standardized by the Internet Engineering Task Force (IETF) in 2013 to be a multi-vendor universal metadata protocol for exporting IP flow information from network devices, such as switches, routers, firewalls to network monitoring and analysis applications or “collector” systems. The IETF IPFIX standard defines how flow information is exported, formatted and transferred from...

A Technical Overview and Deployment Considerations The Internet Protocol Flow Information Export (IPFIX) is a network flow protocol standard defined by the Internet Engineering Task Force (IETF). The IETF IPFIX project was initiated to create a widespread benchmark of export metadata about the traffic flow information from routers, switches, firewalls, and oth...

The right approach to network monitoring and analysis can make all the difference in cutting costs and improving ROI across your business. That’s why the market for network analytics is worth over $3 billion.
