Computer Networks and Network Security

Upon successful completion of the course, the trainee will be able to perform the following specific tasks:

• Describe the fundamental networking models such as OSI and TCP/IP
• Familiarity with different networking topologies such as bus, mesh, star, etc.
• Understand and able to perform network addressing such as IPv4
• The difference between TCP and UDP and their use cases
• Familiarity with the various application layer protocols such as DNS and HTTP
• Describe the structure of a network packet and how are they delivered on the Internet

What You'll Learn

This module provides an overview of the primary technologies used in computer networks with a particular emphasis on the Internet architecture and the various networking protocols involved that make communication possible. Learners will also be introduced to some of the essential tools for analyzing, troubleshooting and monitoring network security and along with that, devices or software which help in securing computer networks. Apart from that, the module covered the core information security principles that are used to secure information transported across computer networks and stored in computer systems. Together, we will explore the many functions of information system protection methods, with an emphasis on cryptography and its key algorithms, which perform varied roles in data security.

Minimum Entry Requirement

Diploma with 2 years of working experience.
