Learn advanced topics in network security, including Security Monitoring, Perimeter Security, IPv6 and IPv6 Security.
This is a self-paced course that provides a continuation of network security topics. Among the topics covered are Security Monitoring, Perimeter Security, IPv6, and IPv6 Security. The material is essential in later classes that will develop ethical hacking skills. Students are introduced to the concept of network security monitoring to detect intrusions instead of merely protecting against them.
Next, we discuss securing the perimeter of networks through the use of firewalls.
We follow up by introducing the student to IPv6: what it is, why it was developed, how it compares to the IPv4 protocol, and techniques to implement IPv6 devices alongside IPv4 devices. This lesson will prepare you for upcoming material focused on IPv6 security issues.
We conclude the course by leveraging the early work in IPv6, and we spend the time discussing IPv6 security. You'll learn about security threats that exist in IPv4 and IPv6 and issues exclusive to IPv6 and countermeasures to these threats.
