Securing Active Directory with Spencer Alessi

How secure is your Active Directory infrastructure? While at Zero Trust World in Orlando, Richard chatted with Spencer Alessi about his work helping companies secure Active Directory, making it more difficult for black hats to exploit it for lateral moves during a breach attempt. Spencer talks about the increasing speed of these exploits, making it much harder to block them after the fact, so it's best to make AD too difficult to target. Jake Hildreth's Locksmith tools are a great place to start - free and open source. There are also Microsoft tools and Spencer's own AD Security Resource Kit to help evaluate your AD infrastructure and lock it down!
