Today was proof that no matter how "normal" the day proceeds, everything can change in a matter of minutes. Something unexpected happened today, and while we proved that security is much more than just a cost to a company, we also realize "mistakes" were made. Well, I wouldn't call it mistakes, but things we can improve on next time, or take into consideration.
Hopefully our client will allow us and assist us in reviewing the events step by step as they occured, and see where we possibly went wrong or made an incorrect assessment of the situation. However, one must take into consideration that it's quite easy to point out "errors" afterwards, whereas during events often split second descisions need to be made and those are then based on all available information at the time. Which is often significantly less than what is available afterwards.
All things considered, I think we handled things the best we could, but with room for improvement. As always, no more information will be made available, unless things are somehow made public by other parties involved.
