Abstract: Unlike network information security which is concerned with data confidentiality and integrity by using techniques like cryptograph, network infrastructure security is concerned with the protection of the network infrastructure itself, that is, to focus on how to detect and prevent routers or other network devices from being attacked or compromised.
Since the Internet, in the beginning, was assumed to work in a trustworthy environment, it was designed without much concern of security. As a result, the infrastructure is vulnerable to a variety of security threats and attacks, such as packet spoofing, routing table poisoning and routing loops.
One of the reasons of why network infrastructure security is important and has drawn much concern in recent years is that attacks to the infrastructure would affect a large portion of the Internet and create a large amount of service disruption. Since our daily operations highly depend on the availability and reliability of the Internet, the security of its infrastructure has become a high priority issue.
This seminar covers comprehensive topics of network infrastructure security -- from lower to higher layer, and from basic concept of network infrastructure security to the research solution to future network device design.
