I'm an Accounting/Economics major myself. And I've been in the field for years, I'd say welcome. We've gotta fill those 1.5 million jobs come 2020 somehow right?
DevSecOps - is a fairly new field in automation of security, i could google that for ya
I'd suggest get started with some AWS track there's a specialty security track (rmr, you have to get the previous ones first) - https://acloud.guru/learn/aws-certified-security-specialty
Also Cisco has their cybersecurity curriculum up as well - https://mkto.cisco.com/Security-Scholarship.html
Other than that, get a job at an early stage start-up angel.co - build up a real-world experience, work for free, maybe run through a few examples of how to get an environment fully under compliance. just don't bullshit.
stay hungry. and you'll be fine. welcome, and welcome again.
