I talked to a lot of people at the conference about how to keep foreign agents out of your network and some of what I learned is in a larger article in Cyber Protection Magazine, but.I went to someone who wasn't there -- Grant Wernick, CEO of #Fletch -- to chat about the problem, how to find them and how to stop them from doing real damage. Grant gave me a view into how you can find them and root them out once they infiltrate.
