A Network Zone is a sub-network defined by its level of trust and security controls. Different zones can have varying security measures based on their intended use and exposure to threats.
Types of Network Zones:
- Trusted zone: High-security area with strict access controls (e.g., internal corporate networks).
- Untrusted zone: Low-security area exposed to external threats (e.g., the Internet).
- Demilitarised zone (DMZ): Intermediate area that separates trusted and untrusted zones, often hosting public-facing services.
Understanding network zones helps organisations implement appropriate security measures and manage risk effectively.
