Network Defense and Countermeasures (Second Edition)

Course ID


Course Description

Network Defense and Countermeasures (Second Edition) is designed to provide network administrators with an awareness of security-related issues and the essential skills they need to implement security in a given network. This is the second course of the Security Certified Program's level one certification track (the SCNP), and focuses primarily on defensive network technologies, such as firewalls and intrusion detection systems.
    Performance-Based Objectives
  • Identify the basic components of a layered structure for network defense architecture, and describe access control objectives and auditing concepts.
  • Identify key concepts and technologies used in the design of firewall systems, as well as methods of implementing firewalls in different scenarios.
  • Implement and configure three unique firewalls and compare their functionality while also identifying the differences between the technologies.
  • Describe Virtual Private Networks (VPNs) and related security issues, and take steps to implement a VPN solution built into Windows 2000.
  • Describe the key concepts of Intrusion Detection Systems, including distinguishing between host-based and network-based Intrusion Detection Systems.
  • Implement and configure a network-based and a host-based IDS.
  • Describe core concepts of TCP/IP packet and signature analysis with the goal of intrusion detection, and examine the goals of the Common Vulnerabilities and Exposure (CVE) project.
  • Identify the concepts and issues related to risk analysis, and analyze different methods of risk analysis, different standards, and different techniques to minimize risk.
  • Implement a security policy for an organization by examining different methods of policy creation and implementation, and creating a policy document.
