Privacy, both in the physical and online world, is one of the things most people value dearly. With the inevitable shift from physical locations and facilities offered by financial institutions, retail stores and government to an online environment, secure communications and transactions are becoming indispensable.

Sophisticated cyber attackers are constantly finding new ways to exploit your network. Whether delivered through drive-by downloads, phishing emails, self-propagation, or any technique in between, all it takes is one malware infection to cost your company millions of dollars. And one thing is clear when it comes to cybersecurity—despite

Traditionally, the foundation of enterprise network security has been a perimeter firewall behind an organization’s Internet gateway or a pair of firewalls encompassing a demilitarized zone (DMZ) which offer an isolated environment between a completely trusted enterprise network and untrusted external network. However, merely characterizing the entire enterprise network as ‘trusted’ and considering it as ‘flat’ (i.e. as a single segment) creates an environment that requires an antagonist to o...

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...

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...

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...

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...

How are you keeping your company from becoming just another data breach statistic? The obvious answer is to build up a secure network infrastructure that keeps even the most advanced attackers at bay.

More and more network traffic is encrypted as people and businesses try to keep their data private and secure as it travels through the Internet. By encrypting transmissions, sensitive information, such as a user's login ID for an online banking session, or perhaps a credit card number, is protected and kept out of the hands of potential hackers and criminal organizations. By 2019,...
