Using Palo Alto Networks, PAN-OS, enterprises can build an IT Security Platform capable of delivering protection against all stages of the Cyber-Attack Lifecycle. From Reconnaissance to Act on Objective, the PAN-OS Single-Pass Parallel Processing (SP3) engine combines efficient throughput with maximum data protection. This recorded webinar will describe how the SP3 Architecture can increase network traffic visibility and enable you to control your environment.

Watch this recorded webinar as CompTIA’s chief technology evangelist and Global Knowledge’s federal sales director discuss how pentesting has morphed.

ITIL® is still recognised as the de facto standard in delivering end-to-end, holistic IT services. The 4th iteration retains ITIL’s place as one of the key tools at the disposal of organization’s seeking to manage digital transformations.

Business processes are complicated, and mapping them is not a trivial task. Modelling standards give us the tools to model complex processes, but they do not tell us the best way to approach a model or effectively use the tool. In this hour-long webinar, Global Knowledge instructor Rod Fage will guide you through the best way to develop a model, from determining the goal and scope of the process and measuring its effectiveness, to modelling the process in a hierarchical top-down approach, enabling business analyst to continuously validate the model.

Despite advances in security, hackers continue to break through network defenses. In this hour-long webinar, network security specialist Catherine Paquet will examine the favorite methods and targets of hackers and will introduce you to the different categories of security technologies. In this foundational presentation, you will learn about the benefits of security solutions such as firewalls, VPNs, IPS, identity services and BYOD.

Often, we don't have time to learn the reasons behind the standards we use. But learning what instigated a standard goes a long way toward not only understanding its importance, but also more easily and effectively applying it in your workplace. In this hour-long webinar, Global Knowledge instructor Keith Sorn will discuss common networking standards and explain how they were determined and why they are relevant. He will fill you in on things like why it's important to use proper color-coding standards when making cable and why the length limitations on wired cable are essential. He will also explain new standards, such as power over fiber.

Instructor John Harmon explains subnetting using binary numbers and decimal conversions.

Instructor John Harmon continues his explanation of subnetting by showing how subnet masks can be used to sub-divide networks.

There are several Wireless LAN Standards, including b, g, and n, which exist in the 2.4 GHz band. These standards need around 20 MHz of radio frequency in order to transmit their signals. In this video, Ben Miller discusses how to pick access points and channels for optimal performance.
