IPv6 and Security

How to Properly Secure Networks and End Devices

The introduction of IPv6 gives rise to new security questions both for providers of enterprise networks and for private customers. After all, IPv6 offers new options to compromise a network. One the one hand, this includes variants of existing types of attack, on the other hand, IPv6 opens up new security gaps. To protect an IPv6 network, it is not merely required to clarify these basic security issues but also to find out whether the components used so far—i.e.firewalls, proxies or intrusion prevention systems (IPS)—are actually equipped for IPv6. Which is the correct method for migration under security aspects? Which changes occur due to the permanent availability of public addresses after the elimination of NAT? Which gaps appear in Windows operating systems due to tunneling mechanisms, such as Teredo, without even migrating to IPv6 and how can these gaps be mended? This course gives a detailed overview of these highly topical questions. The students will learn to assess the level of danger introduced in their networks by IPv6 and to plan comprehensive security measures.

Target Group

This course is designed for planners, administrators and security managers intending to design, prepare, or assist in a migration to IPv6. Attendance at this course can be credited for T.I.S.P. recertification.

Knowledge Prerequisites

The students require sound know-how of the traditional IP world and need to be familiar with the new protocol. Participation in the course IPv6 - Addressing, Routing, and IPv4 Interworking is often recommendable as a preparation. A further requirement is that the students know and understand common security concepts.
