Archived Scores from WCIL May, 2018

Catalog Description

Knowledge and skills required for Network Administrators and Information Technology professionals to be aware of security vulnerabilities, to implement security measures, to analyze an existing network environment in consideration of known security threats or risks, to defend against attacks or viruses, and to ensure data privacy and integrity. Terminology and procedures for implementation and configuration of security, including access control, authorization, encryption, packet filters, firewalls, and Virtual Private Networks (VPNs).

Advisories: Students should have taken CNIT 106 or 106C or 201E, or equivalent familiarity with the fundamentals of networking.

Upon successful completion of this course, the student will be able to:
  1. Define areas of security concern, discuss network security, and identify network risks.
  2. Distinguish between and define internal and external threats to data and services.
  3. Describe the vulnerabilities of various media (susceptibility to wiretaps or eavesdropping).
  4. Secure access to resources on the network using passwords, permissions, and access control lists (ACLs).
  5. Evaluate various anti-virus software programs, software firewalls, and hardware firewalls.
  6. Define and identify types of firewalls, including Network Address Translation (NAT).
  7. Discuss weaknesses of various operating systems and known and recommended fixes (patches).
  8. Detect unauthorized attempts to access resources by monitoring (auditing).
  9. Install and configure intrusion detection programs; analyze reports and recommend responses.
  10. Provide solutions for known vulnerabilities in communications: email, remote access, file transfer, and electronic commerce.
  11. Provide end-to-end security for the transmission of data between hosts on the network.
  12. Describe vulnerabilities inherent in wireless technologies and present suggested solutions.

Student Learning Outcomes (measured to guide course improvements)

1. Define areas of security concern, discuss network security, and identify security risks
2. Evaluate various anti-virus software programs, and compare to software and hardware firewalls
3. Discuss weaknesses of various operating systems and known and recommended fixes (patches)
