Cyberspace is the virtual environment created by interconnected computer systems and networks. It is a non-physical domain where digital communication and data exchange occurs.
- Term coined by William Gibson in 1984 novel "Neuromancer"
- Encompasses all networked digital systems globally
- Exists through interaction of hardware, software, and human users
2. Characteristics of Cyberspace
| Characteristic | Description |
|---|---|
| Borderless | No geographical boundaries |
| Anonymous | Users can operate with varying degrees of anonymity |
| Dynamic | Constantly evolving with technology |
| Persistent | Data and actions have lasting effects |
| Interconnected | Billions of devices linked globally |
3. Three Layers of Cyberspace
Layer Model:
- Physical Layer: Hardware, cables, servers, data centers
- Logical Layer: Software, protocols, applications, data
- Social Layer: Human users, identities, communities
4. Components of Cyberspace
- Infrastructure: Routers, switches, servers, cables, satellites
- Protocols: TCP/IP, HTTP, DNS, SSL/TLS
- Applications: Web browsers, email, social media, cloud services
- Users: Individuals, organizations, governments
- Data: Information stored, transmitted, and processed
5. Importance of Cyberspace
- Global communication and collaboration
- E-commerce and digital economy
- Critical infrastructure operations
- Government and military operations
- Education and research
- Entertainment and social interaction
6. Cyberspace Security Concerns
- Cyber attacks and threats
- Data breaches and privacy violations
- Identity theft and fraud
- Critical infrastructure attacks
- State-sponsored cyber warfare
Key Point:
Understanding the nature of cyberspace is fundamental to cybersecurity. Security measures must address all three layers to be effective.
