CPTR 427 Network Security


Course Description

This course provides an overview to key issues and solutions for network security and privacy issues. It provides an introduction to cryptography and its application to network and operating systems security; security threats; applications of cryptography; secret key and public key cryptographic algorithms; hash functions; authentication; security for electronic mail; intrusion detection; malicious software and firewalls. This course provides the necessary information to prepare for the CompTIA Security+™ exam SY0-501.

Purpose, Goals & Objectives

The purpose of this course is to introduce students to the real world of network security. Because this is an important, fast growing and changing field, the course goal covers training students to research security related information and implement the solutions found to protect vital assets. To accomplish these goals the student will research a chosen area and setup or write the necessary software on his/her own system. They will then prepare a lecture on the value, implementation and effectiveness of the chosen topic. Lecture topics may include:

  • What is Security?
  • Cryptography
  • Symmetric and asymmetric key cryptography
  • Hashes & Message Digests

  • Public Key Algorithms & Infrastructure

  • Number Theory Authentication
  • IPSec
  • Mail/GNU Privacy Guard
  • Hardening Issues
  • Windows
  • Firewalls
  • Web Issues
  • Intrusion Detection and Prevention
  • Wireless
  • Security Tools

Upon successful completion of this course, students will be able to:

  • Understand the basic security concepts applicable to system administration
  • Develop skill to be able to find useful security information
  • Develop skill to be able to understand the legal and ethical responsibilities as a network security administrator
  • Present anoral lecture and poster presentation on their own project.
  • Develop skill to be able to evaluate the effectiveness of security information
  • Develop skill to be able to understand the basics of security research
