Distributed Denial of Services (DDoS) Overview Denial of service is a form of cyber-attack in which attackers overload computing or network resources with so much traffic that legitimate users are prevented from accessing to online services such as online banking and e-commerce. Enterprise websites are a preferred target since they provide the most engagement with an organization’s customers, partners, subscribers and followers.

How Visibility Can Make or Break a Hybrid Network The modern enterprise IT team faces a seemingly impossible task. More and more, IT leaders are under pressure to dramatically increase agility, maximize workforce productivity, eliminate any security threats, and address every compliance requirement—all while cutting costs. As business leaders accelerate digital transformation initiatives, there’s a fundamental misconception ...

There’s one glaring problem with modern security tools. Even if you’ve deployed next-gen firewalls (NGFW), intrusion prevention systems (IPS), data leakage prevention and more, they’re all useless without total visibility of network packets.

Network visibility isn’t a luxury—it’s a necessity if you want to keep applications running smoothly and sensitive data secure. But the simple, SPAN port-driven approaches to network visibility that worked in the past aren’t enough anymore. As your network architecture expands and...

Introduction – The SSL Inspection Imperative Security—as defined by the combination of confidentiality, integrity, and availability—is vital for protecting web-based transactions. Secure Sockets Layer (SSL) due to its flexibility is the ubiquitous choice for securing ecommerce. SSL is most commonly implemented in the form of secure hypertext transport protocol (HTTPS). This secure link ensures that data passed between the web server and the bro...

The networking and communications market is at a crucial juncture as it looks to adopt Software Defined Networking (SDN). Legacy networks have become very complex and hard to manage due to interoperability and upgrade requirements, advancing protocols, and management practices typically hard-coded into underlying hardware platforms.

As the saying goes: “Seeing is believing”. Seeing gives you the ability to react very quickly to what you view – on a required basis. In contrast, it also enables you to take your time to thoroughly study a situation (maybe viewing it from different angles and perspectives) before you go ahead and decide to act. This is the power of the user interface (UI) – specifically the graphic user interface (GUI). It optimizes the user experience (UX) and empowers

Everyone’s talking about Network Visibility and how essential it is for network stability and security. However, to really understand its importance, you have to examine each component of network visibility and how it contributes to the overall picture. It’s imperative to consider how each network visibility component interfaces with and complements other components and how critical an effective visibility layer is in supporting robust network security. In today’s post, we’ll cover ne...

For some reason, whenever I hear the term Load Balancing, I think of a circus high-wire act. Similar to the person walking on a relatively thin cable wire – about 50 or more scary feet above the ground – holding a long vertical bar for equilibrium. The analogy more or less stops with that bar (which helps the acrobat keep his or her balance). That acrobat uses the balancing bar – on a wire – and carries out a precision act in order not to fall. <...
