In contrast to the other components of enterprise networks, the wide-area network (WAN) stands out as the most demanding to administer because it often includes a variety of services and devices with most of those devices at unsupported sites. Management and upgrading is difficult; often remote access to WAN devices is only possible via the WAN itself, so resolving any major errors made during an upgrade may demand physical access to the device itself.

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...
