Why Cyber Law Matters (Especially for CSE Students)
- Protects users and organizations: Reduces cyber risks and legal exposure.
- Builds trust in the digital economy: Enables secure payments, online services, and fintech.
- Ensures compliance: Guides how apps, websites, and databases handle user data.
- Supports cybersecurity practice: Defines what is lawful in testing, logging, monitoring, and incident response.

Quick Takeaway
Cyber law is the legal backbone of the online world. It protects people, data, and businesses; validates e-transactions; and penalizes cybercrimes. For CSE students, understanding cyber law is essential for building compliant, secure technologies and for acting ethically in the digital ecosystem.
