Building Security Culture
The strongest ISMS is built on culture, not just policies and controls.
What is Security Culture?
Shared beliefs, attitudes, and behaviors regarding information security.
Not: Annual training checkbox, fear-based compliance Instead: Genuine awareness, proactive behaviors, shared responsibility
