🔐 Introduction to Cyber Security: Overview and Protection Levels
The video starts by introducing the concept of cyber security as the continuous effort to safeguard individuals, organizations, and governments from digital threats. It explains that the course will cover fundamental topics, scenarios, and attacks to familiarize viewers with the core concepts and frameworks in the field. Three levels of protection are highlighted: personal, organizational, and governmental.

🛡️ Protecting Personal Data: Offline and Online Identities
This section delves into the concept of personal data, explaining how both offline and online identities can be vulnerable to cyber threats. It clarifies that even those without social media accounts have an online presence if they use the internet. Offline identity refers to personal information shared in daily life, while online identity involves digital footprints left on social media and websites. The importance of safeguarding sensitive information like name, date of birth, and bank details is emphasized, as cybercriminals can use this data to commit identity theft and financial fraud.
