I’ve always found that cybersecurity rewards the same mindset that helps you appreciate a new place: pay attention, stay patient, and look twice at the things most people walk past without noticing. Most of the progress we make as analysts doesn’t come from big breakthroughs — it comes from steady follow-through, checking one more detail, and being willing to revisit something that didn’t seem important at first. That pace suits me just fine.
🔒 Security Tip of the Week:
When reviewing alerts, trace activity across context, not just single events. A login, an IP change, or a process start might look normal alone, but when you line them up, the pattern often reveals what the individual pieces hide. Small clues tend to make the biggest difference when viewed together.
And of course, if you need any assistance with any of the above or want a complete assessment done, contact Pinpoint Security today to learn how we can help!
