The FIRST EDITION of Black Hills Information Security's The Infosec Survival Guide is filled with free resources to help you with your career.
There's a easy to solve challenge inside and if you solve it, you get access to information security challenges and if you solve those, you'll receive a month of free access to the Antisyphon Training Cyber Range for you to build and hone your skills.
This guide is normally handed out for free at information security conferences, but we have it here on the store if you're unable to make it to your local or national security conference.
