Continuing Professional Education for Audit, Assurance, & Info Security

Course Description

Data network infrastructures provide the highways of accessibility to modern business applications; however, these high speed data highways, if improperly safeguarded, can also open avenues of external and internal attack and abuse. Over the years, for a variety of reasons, the topic of auditing networks has often been misunderstood and viewed as a technical mystery. In this down-to-earth, no nonsense workshop, we will clearly identify and demonstrate practical methods to discover, document and audit the critical control points, risks, and safeguards in numerous forms of common network technologies, both internal and external, Internet facing infrastructures used in most modern organizations.

In addition to control issues common to both internal and external network infrastructure security controls and audit procedures, such as network device security and change control, we identify the main IT audit focal points for public/Internet connections including: firewalls and proxy servers, virtual private networks

Learning Objectives

  • Understand how networks work and where important CyberSecurity control points are located in different network scenarios
  • Utilize the OSI and TCP/IP protocol stack models to position different types of CyberSecurity controls and IT audit objectives
  • Understood key risks and security controls for TCP/IP applications and network appliances
  • Identify tools and techniques for performing useful CyberSecurity risk assessment of network applications on internal and external networks
