Spine-and-leaf data center architecture has been a major benefit to network designers trying to keep up with ever-increasing business demands. You’re tasked with supporting data-heavy applications, bandwidth-hungry communications systems, and more connected endpoints—all with fewer resources to scale the data center. And while spine-and-leaf designs have helped us get by, we’re quickly reaching the limits of their scalability.

One of the greatest impediments that security teams face in dealing with escalating threats and increasing data breaches is the lack of agility. While new security technologies and solutions come on the market quickly, security teams have been slow to adopt them. It is difficult and time consuming to add a new security solution to the network or make changes or upgrades to existing ones. Limited ports and rack space, along with the complex or convoluted task of getting a change or add...

As part of the Niagara Network Partner Showcase series, we introduce our partner’s solution and elucidate the optimization and added value achieved by combining Niagara’s and our partner’s offering together.

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...

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

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

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...

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

“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,
