Excerpt from One Thing Leads to Another:

The Challenge: John is the I.T. Manager for a movie company working on the special effects for a hit film.... But the fan site has just posted an unauthorized clip of one of the most anticipated scenes in the movie.... A postproduction team member put the clip on the server but no one accessed it after that, at least not via FTP.... Then it happened again: more footage was released.... The Web master of the fan site supplied the e-mail address from which he received the files. John checked the ssh logs and the Web server logs.... He found an IP address he had not seen before.... He pinged the IP address then checked his arp table to get the machines MAC address.... He began tracing the cable back to its source: the proxy server, which had not been used in 8 months....

The Solution: After reviewing the log files included in the challenge, propose your assessment: How could the employees have approached the initial investigation differently that may have helped them get to the culprit sooner? What does the lack of evidence in the ftp and ssh logs reveal? Was Johns method of tracking down the proxy server the best method? What is the best solution to solve the vulnerability? Then, turn to the experts answers to find out what really happened.
