Major cyber threats we face in 2025:

**Advanced Persistent Threats (APT)**
- Sophisticated attacks by nation-state actors
- 400% increase in supply chain attacks
- Commercialization of zero-day exploits
- Rise of Living off the Land (LotL) techniques

**AI-Powered Attacks**

### Zero Trust Architecture: Never Trust, Always Verify

Zero Trust is a modern security paradigm based on the principle of "never trust, always verify":

**Core Principles**

1. **Explicit Verification**
   - Verify every access request
   - Multi-factor authentication (MFA) requirement
   - Risk-based adaptive authentication
   - Continuous session validation

2. **Least Privilege Access**
   - Just-in-time (JIT) access management
   - Privilege Access Management (PAM)
   - Role-based access control (RBAC)
   - Attribute-based access control (ABAC)

3. **Assume Breach**
   - Blast radius minimization with microsegmentation
   - Lateral movement prevention
   - Data loss prevention (DLP)
   - Encrypted data at rest and in transit

**Zero Trust Implementation Roadmap**

**Phase 1: Identity Foundation (0-6 months)**
- Strong authentication deployment
- Single Sign-On (SSO) integration
- Identity governance and administration
- Privileged account discovery

**Phase 2: Device Trust (6-12 months)**
- Endpoint detection and response (EDR)
- Mobile device management (MDM)
- Certificate-based authentication
- Device compliance policies

**Phase 3: Network Segmentation (12-18 months)**
- Software-defined perimeter (SDP)
- Microsegmentation deployment
- East-west traffic inspection
- Cloud security posture management (CSPM)

**Phase 4: Data Protection (18-24 months)**
- Data classification and labeling
- Rights management services
- Cloud access security broker (CASB)
- Homomorphic encryption pilot
