Greetings Forensicators, Incident Responders and other cool people. I've called this week's article The Gauntlet Edition because a number of organizations have recently thrown down the gauntlet and introduced some cool forensics challenges. Sometimes, the best tool in our arsenal is neither software, nor hardware, nor even our wetware. In many cases, the best tool we can have is a challenge. More than anything else I can think of, it's the process of working a case and rising to a new challenge that really causes us to sharpen our skills. Whether the problem is new to the community, or just new to us, working it through to a solution or an answer is what really causes us to upgrade our wetware.
In that spirit, I've provided a list of recently announced and upcoming challenges, along with our usual assortment of cool tools, good reads and other forensic fun. I encourage you all to pick up The Gauntlet and try your hand at one or more of the challenges listed below. Even if you're new to the field or are not confident in your abilities, give it a try and see how far you get. Even if you don't submit a solution, your attempt to work through one or more of these challenges will make the winning submissions more meaningful when they are announced and available for reading.
If you know of Challenges I've missed, please let us know in the comments section. Also, if you have news or links to share, you can send them to us at caseleads [AT] sans [DOT] org.

"In other words, if it's still 6/27/10 anywhere in the world, you can submit your entry." Winners will be announced June 8, 2010 at the SANS Forensics and Incident Response Summit in Washington D.C. There are prizes for the top 3 teams.

- Rich Mogull has an interesting post over on the Securosis blog: FireStarter: The Only Value/Loss Metric That Matters. He discusses the difficulty (nay, impossibility?) of valuing information assets and predicting losses due to a security incident. Then, over on his TaoSecurity blog, Richard Bejtlich picks this up an runs with it, briefly discussing the difficulty of calculating the cost of an incident after it has happened. And if we can't easily or successfully calculate losses from an incident that has already occurred, we have little-to-no hope of projecting future costs of incidents.
- Over at Law Technology News, Leonard Deutchman has an thorough and interesting article on the application of the Plain View doctrine to computer searches. In his article, To Avoid 'Plain View,' Investigators Need Blinders, Mr. Deutchman provides some background on reasons that the 1st, 4th and 7th U.S. Circuit Courts of Appeal have applied the plain view doctrine to computer searches, where the 9th Circuit Court rejected it, then goes on to provide some insightful analysis of the issue.
