Information Security Training

In this Information Security Training course, you will gain the foundational knowledge and skills to analyse and assess network risks and then select and deploy appropriate countermeasures.


  • Evaluate methods for strong authentication.
  • Search for possible vulnerabilities in operating systems.
  •  Reduce your organisation’s' exposure to dangers in enterprise-wide and virtual private networks (VPNs).
  • Analyse your exposure to security threats.
  • Protect your organisation's systems and data.
  • Deploy firewalls and data encryption to minimise threats.
  • Assess alternative user and host authentication mechanisms.
  • Manage risks originating from inside the organisation and from the internet.
  • Leverage continued support with after-course one-on-one instructor coaching and computing sandbox.
