Backscatter-tocs (02/01/2001 to 03/06/2004)

Information useful for studying denial-of-service (DoS) attacks. This dataset consists of IPv4 packets sent by DoS attack victims in response to spoofed attack traffic. This backscatter from victims was collected by the UCSD Network Telescope. Possible uses include modeling DoS attacks, understanding victim populations, and using real packet traces to validate algorithms for detecting or classifying malicious traffic. This last use is particularly valuable because it is extremely challenging to artificially generate the kind of real-world noise present on the Internet. This dataset includes just the subset of CAIDA's backscatter data used for the paper "Inferring Internet Denial-of-Service Activity" published in ACM TOCS, May 2006.
