3-Day Enterprise Grade Android Security for Cyber Operations

Enterprise Grade Android Security for Cyber Operations

Length: 3 Days

Type: Hands-On

Target Audience: IT Managers, Security Personnels.


In this hands-on course, combining both Android Application Security and Android Enterprise Security modules, you will learn about Android security at all possible levels, from the bootloader, through identifying weaknesses in applications, finding data breach, and applying Enterprise Mobility Management policies at the device. We will learn how to harden both the Operating System (for device builders), and the running device policies,in order to protect the organization’s Intellectual Property and data, via in-depth inspection of the Android Platform and ecosystem. To conclude, we will address Android For Work, discussing and applying Android Provisioning services to support an IT manager perspective. The course is intended for IT Managers and Security personnels with practical Java experience. No previous Android experience is required, but it is highly recommended.


Note: The course is based on the Marshmallow version. Earlier versions can be targeted without additional cost, upon customer request.
