Zero Trust Security
Zero Trust is a cybersecurity model that assumes no user, device, or system is trusted by default. Every access request is verified, regardless of whether it originates inside or outside the network perimeter. This approach reduces the risk of breaches and lateral movement by attackers.
Core Principles
- Verify Explicitly: Always authenticate and authorize every access request.
- Least Privilege Access: Provide users and devices only the access needed for their tasks.
- Microsegmentation: Divide networks into smaller zones to contain potential breaches.
- Continuous Monitoring: Track user activity, device health, and network traffic in real-time.
Practical Implementation
- Use strong authentication methods (MFA) for all users and devices.
- Segment access to critical systems and sensitive data.
- Continuously assess device security and compliance before granting access.
- Monitor network traffic and user behavior to detect anomalies.
- Integrate with identity and access management (IAM) solutions.
Benefits
- Reduces attack surface and lateral movement inside networks.
- Enhances protection of cloud and on-premise resources.
- Supports compliance with regulations like HIPAA, PCI-DSS, and GDPR.
- Improves overall security posture with continuous monitoring.
Bottom line: Zero Trust is a modern security approach that requires continuous verification and least-privilege access, providing robust protection against modern cyber threats.
