"I run regular audits to ensure data integrity across systems. In my audits, I often come across a handful of errors that I'm able to correct before they get buried or forgotten, so I've found this to be a particularly powerful proactive measure. When I run into a challenge with database security, my first reactive measure is always to cross-reference my user access spreadsheet with database login history. This helps me to identify whether or not the security issue is from an internal or external source, and I can run further checks from there."
