Before I move on to specifics, in the interests of transparency, you should know that I have some tangential relationships with the organizations discussed in this report.
In particular, I am an active member of the FBI's InfraGard program, where as part of an industry/government partnership, I serve as one of the nation's cybersecurity infrastructure guardians, along with other infrastructure professionals across the country.
I also led a team that included senior White House officials in a nationwide cyberattack simulation. None of those officials are part of the Hillary Clinton campaign, rather they were involved in the George W. Bush administration. I have also lectured on cybersecurity to American military and policy leaders at the National Defense University.
Finally, as many of you know, I wrote a book that investigated the Bush 43 administration's misuse of White House email. That book is called Where Have All the Emails Gone? and is now available as a free download [PDF].
During and after the publication of that book, I have had numerous conversations and discussions about my observations on government email security with currently serving government officials in the Obama administration, in various agencies, in the military, and at various levels of the US judiciary system.
