Get to know William Lidster

Question: Why did you decide to pursue cybersecurity as a career path?
Answer: Cybersecurity became front-and-center for most organizations globally in 2001, and I was already dabbling in it as an additional consideration with my IT management duties. I felt that cybersecurity was going to be a far more interesting and challenging field, so I pursued my first certification and then started pursuing opportunities that were solely focused on cybersecurity.

Q: How would you describe your feelings about cybersecurity in one word?
A: Challenging.

Q: What has been your most memorable moment thus far working in cybersecurity?
A: The opportunities that I have had to help others find their career path and grow in the field.

Q: What led you to join your current organization (employer)?
A: My organization has a culture of care and kindness and service to its members. Anyone who does not embrace that probably won't be successful there. With that culture comes an environment of great teamwork. I have, undoubtedly, one of the best jobs ever.

Q: If you had to choose, what's the one cybersecurity practice people can adopt that would have the greatest impact?
A: Outside of training and awareness, full-on MFA (multi-factor authentication). It is a great way to prevent lateral movement and elevation of privileges which are key to a successful breach.

Q: What is an industry-wide change you would like to see happen in 2023?
A: Far more focus on technologies and capabilities to detect and stop intrusion. We have an imbalance of effort on just prevention, and we are still limited in our capabilities to detect/respond when prevention fails.

Q: What are you most looking forward to at SecureWorld this year?
A: Hoping to see new thoughts and conversations that break out of the older mold and into really creative topics and approaches for solutioning to our challenges.
