Sysadmins were always the ones who focused on making things secure, and for a bunch of reasons they basically don’t exist anymore.
EDIT: what guidelines did I break?
I guess it's fine if you get rid of sysadmins and have dev splitting their focus across dev, QA, sec, and ops. It's also fine if you have devs focus on dev, QA, code part of the sec and sysadmins focus on ops and network part of the sec. Bottom line is - someone needs to focus on sec :) (and on QAing and DBAing)
True, but over the last twenty years, simple mistakes by developers have caused so many giant security issues.
Part of being a developer now is knowing at least the basics on standard security practices. But you still see people ignoring things as simple as SQL injection, mainly because it's easy and they might not even have been taught otherwise. Many of these people can't even read a Python error message so I'm not surprised.
And your cybersecurity department likely isn't auditing source code. They are just making sure your software versions are up to date.
And you go home at 5pm and had a good work day.
