Notes on Cyber Security Engineering Lecture

Overview of Cyber Security

• Data Growth: By 2028, humanity's data will reach 394 zettabytes (ZB).
• AI Technologies: Tools like ChatGPT, GitHub Copilot, and self-driving cars increase reliance on digital tools.
• Cyber Threats: Increased connectivity leads to greater vulnerability to hacking and cyber threats.
• Statistics: 3rd largest economy in cyber crime, after USA and China.

Importance of Cyber Security

• Targets include hospitals, schools, and big tech companies.
• Personal Data Exposure: Every online action (shopping, social media) can expose personal information to hackers.
• Demand for Cyber Security Professionals: Over 21,000 job openings in India; 5.5 million global shortfall by 2025.
