System and Network Security: A Comprehensive Introduction

Course: 468   Type: Workshop   Duration: 4 Days
Quick Enrol  

You Will Learn How To

  • Analyse your exposure to security threats and protect your organisation's systems and data
  • Reduce your susceptibility to an attack by deploying firewalls and data encryption
  • Assess alternative user and host authentication mechanisms
  • Manage risks emanating from inside the organisation and from the Internet
  • Protect network users from hostile applications and viruses
  • Identify the security risks that need to be addressed within your organisation

Course Benefits
In today's Internet-dependent business environment, organisations must link their systems across enterprise-wide and virtual private networks, as well as connect mobile users. Each connection increases exposure to customers, competitors and hackers, magnifying vulnerability to attack. In this course, you learn how to analyse risks to your networks and the steps needed to select and deploy the appropriate countermeasures to reduce your exposure to network threats.

Who Should Attend
Those who require the fundamental skills to develop and implement security schemes designed to protect their organisation's information from threats.

Course Workshops
Exercises and workshops provide you with experience analysing system and network security. Activities include:
  • Cracking passwords
  • Scanning systems with Microsoft Baseline Security Analyzer (MBSA)
  • Restricting computer access with biometrics
  • Preventing unwanted network access with a personal firewall
  • Encrypting and signing important data
  • Discovering security best practices
