System and Network Security Training

In this Network Security Training course, you will gain the foundational knowledge and skills to analyse and assess network risks, then select and deploy appropriate countermeasures. Through multiple hands-on exercises, you will learn how to:

• 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 ( VPN s)

System and Network Security Training Delivery Methods

• In-Person

• Online
