Disk Images
The Harvard/MIT Drive Image Corpus. Between 1998 and 2006, Garfinkel acquired 1250+ hard drives on the secondary market. These hard drive images have proven invaluable in performing a range of studies such as the developing of new forensic techniques and the sanitization practices of computer users.

Network Packets
The DARPA Intrusion Detection Evaluation. In 1998, 1999 and 2000 the Information Systems Technology Group at MIT Lincoln Laboratory created a test network complete with simulated servers, clients, clerical workers, programmers, and system managers. Baseline traffic was collected. The systems on the network were then “attacked” by simulated hackers. Some of the attacks were well-known at the time, while others were developed for the purpose of the evaluation.

Other Corpora
The Canterbury Corpus is a set of files used for testing lossless compression algorithms. The corpus consists of 11 natural files, 4 artificial files, 3 large files, and a file with the first million digits of pi. You can also find a copyof the Calgaruy Corpus at the website, which was the defacto standard for testing lossless compression algorithms in the 1990s.
