Cisco IINS 1.0: Network Security Principles I

This course is included in our On-demand training solution.


The open nature of the Internet makes it increasingly important for growing businesses to pay attention to the security of their networks. As companies move more of their business functions to the public network, they need to take precautions to ensure that their data remains uncompromised. With the challenges of increased availability requirements and growing regulatory requirements, establishing and maintaining a secure network computing environment is becoming increasingly difficult.
This course provides an explanation of the core principles that are part of the secure network environment. It explains how sophisticated attack tools and open networks generate an increased need for network security and dynamic security policies, the primary objectives of security and primary types of security controls, as well as some of the factors that are involved in responding to a security breach. Examining who hackers are, what motivates them, and how they do what they do, as well as variety of attacks against confidentiality, integrity, and availability and some of the best practices to defeat them are also covered. This course is one of a series from the IINS 1.0 SkillSoft learning paths which cover the objectives for Cisco exam 640-553 IINS 1.0.
