Zero Trust Security: Paradigma Baru Keamanan Enterprise

Zero Trust adalah security model yang tidak automatically trust siapapun atau apapun di dalam atau luar network perimeter.

Prinsip Zero Trust:

1. Verify Explicitly
- Authenticate dan authorize berdasarkan all available data points
- Multi-factor authentication (MFA) mandatory
- Continuous verification, bukan one-time authentication

2. Least Privilege Access
- Just-in-time dan just-enough-access (JIT/JEA)
- Risk-based adaptive policies
- Data protection dengan encryption

3. Assume Breach
- Minimize blast radius dengan segmentation
- End-to-end encryption
- Analytics untuk threat detection

Implementation Framework:

1. Identity & Access Management
- Single Sign-On (SSO) dengan MFA
- Identity governance
- Privileged access management

2. Device Security
- Endpoint detection and response (EDR)
- Mobile device management (MDM)
- Device health verification

3. Network Segmentation
- Micro-segmentation
- Software-defined perimeter (SDP)
- Zero Trust Network Access (ZTNA)

4. Data Protection
- Data classification
- Data loss prevention (DLP)
- Encryption at rest dan in transit

5. Monitoring & Analytics
- Security Information and Event Management (SIEM)
- User and Entity Behavior Analytics (UEBA)
- Threat intelligence integration

Challenges:
- Legacy systems yang tidak support modern authentication
- User experience vs security trade-off
- Complexity dalam implementation
- Cost dan resources required

ROI dari Zero Trust:
- Reduced risk dari data breaches
- Better compliance dengan regulations
- Improved incident response time
- Enhanced visibility terhadap security posture

Kesimpulan: Zero Trust bukan produk yang bisa dibeli, tetapi journey yang membutuhkan commitment, planning, dan continuous improvement.
