GK# 3436

Course Overview


This course provides a unique, in-depth look at the major business challenges and threats that are introduced when an organization's network is connected to the public Internet. This course also provides a comprehensive explanation of network security basics, including how hackers access online networks and the use of Firewalls and VPNs to provide security countermeasures.

In addition to premium instructional content from Jones & Bartlett Learning's comprehensive Information Systems Security and Assurance (ISSA) curriculum, this course provides access to a customized "virtual sandbox" learning environment that aggregates an unparalleled spectrum of cybersecurity applications. Providing instant, unscheduled access to labs from the convenience of a web-browser, this course allows you to practice "white hat" hacking on a real IT infrastructure-these are not simulations. Winner of the "Security Training and Educational Programs" top prize at the prestigious 2013 Global Excellence Awards by Info Security Products Guide, the industry's leading information security research and advisory guide, these labs provide valuable exposure to complex, real world challenges and over 20 hours of training exercises on how hackers and perpetrators use these applications and tools.
