Course Reviews

Very broad overview, excellent! I liked repeating basic principles and the very good explanations of hard-to-understand things. The trainer had very good and clear speaking skills even for non-native English speaking audience.

Description

The past few years have seen a massive increase in attacks, data breaches and medical identity theft targeting the healthcare industry; there have also been various ransomware attacks paralyzing healthcare computer networks as well as the various medical devices connected to them. The rise of mobile devices used in the industry needs to be addressed as well: there is a huge growth of medical software applications for mobiles and tablets that connect the patient with the organization – carrying and storing personally identifiable information (PII).

Healthcare is one of the business domains where security is absolutely crucial. Vulnerability is not an option when working with life-saving devices. There is also significant compliance pressure – if you want to stay a trusted and reliable vendor, your systems and applications need to comply with Health Information Portability and Accountability Act (HIPAA) requirements. To deal with these challenges, you need motivated secure coders with the right skills and the right attitude to fight security problems: a skilled team of software engineers as well as network administrators.

This training program exclusively targets engineers developing applications or maintaining networks for the healthcare sector. Our dedicated trainers share their experience and expertise through hands-on labs, and give real-life case studies from the healthcare industry – engaging participants in live hacking fun to reveal all consequences of insecure coding.
