“If a company gets hacked, no CIO wants to have the board ask what happened and say, ‘Damn if I know.’ They want to say, ‘We’re going through log data to find out what happened.”—Eric Ogren, Senior Analyst at 451 Research. Designing a secure network infrastructure has become increasingly difficult. It’s not enough to deploy a stack of security tools like firewalls,

The vast majority of the time, packet duplication is seen as a serious problem for network visibility. When duplication occurs on the network traffic, it may indicate a network issue, however, often packet duplication is associated with the deployment of the network visibility layer itself, whereby network tools and appliances receive for processing the same packet from different locations or often the very...

It would be understandable if network security pros felt like they were constantly fighting a losing battle. Between 2018 and 2019, global cybersecurity spending increased nearly 10% to $103 billion. And yet, as you increase cybersecurity spending, attackers continue to successfully break through network security infrastructure.

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...
