IMPACT
I was honored to deliver a Cyber Awareness Session to the youth of the Milan Community, focusing on real-world online threats, digital responsibility, and practical strategies for staying safe in today’s connected world.
As technology becomes an essential part of everyday life, cyber awareness is no longer optional. During the session, we covered online privacy, data protection, strong password practices, social engineering risks, and responsible digital behavior. The goal was clear: to equip young individuals with the knowledge and confidence to protect themselves and make informed decisions online.
The engagement, curiosity, and thoughtful questions from the Milan Community Youth made the session truly impactful. It was a privilege to contribute to building a more informed and security-conscious generation. Educating and empowering youth in cybersecurity is not just an initiative; it is a responsibility.
