Not all techniques used by cyber attackers are strictly malicious. A port scan attack is just one classic example of a normal security technique being used against the very networks it’s designed to help protect. But this shouldn’t come as a surprise. Port scanning has been a key technique for security pros to conduct service discovery across their networks, and if it works for the blue team, it certainly wor...

For many networking teams, the great network visibility debate revolves around taps vs. SPAN ports. However, as network monitoring demands continue to increase, the drawbacks of SPAN ports, also known as mirror ports, are becoming clearer. Compared to

Over the last few years, encryption has become one of the highest priorities for cybersecurity improvements. As important as it is to have strong password policies, advanced firewalls, and secure storage arrays, encryption gives you protection from attackers who would otherwise intercept your data in transit. From a business user perspective, encryption means web browsing and application usage is completely secure. But just because up to

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.

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...

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 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.

Why SSL Decryption? The growing adoption of protocols to secure Internet traffic, including Secure Socket Layer (SSL) and Transport Layer Security (TLS), is, paradoxically, giving cybercriminals a way to evade network defenses. For example, Gartner Group predicts that, through 2019, more than 80 percent of enterprises' web traffic will be encrypted and that during 2019, more than 50%o...

Critical Enabler for Robust Network Visibility Over the last few years, network equipment manufacturers have been in the process of broadly adopting fan-out technology for data center networking to increase port density. In this blog, we will examine how port fan-out technology overall enables higher scalability and flexibility for next-generation data centers and, when specifically applied to Niagara Networks N2 network bypass and
