What the heck is cybersec

There is a lot of info out there, but it all seems very chaotic, driven by a madly competing marketplace of would-be vendors... Trying to orient myself.

Some stuff they are giving me at school:

• NetLabs
• NCL National Cyber League game
• OWASP Security Shephard
• Facebook Codepath (incl Capture the Flag)

Stuff out on the free web:

• Hacker High School
• Hac-King-Do - $10/mo
• Trail of Bits CTF guide
• Lifehacker's Bug Bounty Hunter article (more links)
• Cybrary
• Hak5 hacker lesson TV
• OpenSecurityTraining.info
