Hogg (advanced technology director, Global Technology Resources, Inc.) and Vyncke (Cisco Distinguished System Engineer, consultant) provide details of the security risks, threats, and challenges inherent as the world's networks begin to adopt the IPv6 protocol. The book offers instruction in how to avoid security problems before IPv6 becomes widely used, security shortcomings, and how to correct them. It also includes best practices for identifying and resolving weaknesses during maintenance of a dual stack network. The authors also discuss Cisco products and protection mechanisms, how to use Cisco IOS and ASA firewalls, and securing hosts with Cisco Security Agent 6.
