System and Network Security: A Comprehensive Introduction
Course: 468
Type: Course Workshop
Duration: 4 Days
You Will Learn How To
- Analyze your exposure to security threats and protect your organization'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 organization and from the Internet
- Protect network users from hostile applications and viruses
- Identify the security risks that need to be addressed within your organization
Course Benefits In today's Internet-dependent business environment, organizations 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 analyze 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 organization's information from threats.Course Workshop Exercises and workshops provide you with experience analyzing system and network security.
