# Implementing Pci Dss Compliance Controls


## Genel Bakış
PCI DSS 4.0.1 establishes 12 requirements across 6 control objectives for organizations that store, process, or transmit cardholder data. With PCI DSS 3.2.1 retiring April 2024 and 51 new requirements becoming mandatory March 31, 2025, bu skill covers implementing all requirements including the new customized validation approach, enhanced authentication, and continuous monitoring controls.


## Ne Zaman Kullanılır

- Dağıt:ing yaparken or configuring implementing pci dss compliance controls capabilities in your environment
- establishing yaparken: security controls aligned to compliance requirements
- building yaparken or improving security architecture for this domain
- conducting yaparken security assessments that require this implementation

## Ön Gereksinimler
- Understanding of payment card processing flows and cardholder data environment (CDE)
- Bilgi: network segmentation and security architecture
- Erişim: cardholder data environment for scoping
- Understanding of PCI compliance validation levels (merchant levels 1-4, service provider levels 1-2)

## Core Concepts

### 12 PCI DSS Requirements by Control Objective

**Build and Maintain a Secure Network and Systems**
1. Install and maintain network security controls (firewalls, NSCs)
2. Apply secure configurations to all system components

**Protect Account Data**
3. Protect stored account data (encryption, tokenization, truncation)
4. Protect cardholder data with strong cryptography during transmission

**Maintain a Vulnerability Management Program**
5. Protect all systems and networks from malicious software
6. Develop and maintain secure systems and software

**Implement Strong Access Control Measures**
7. Restrict Erişim: system components and cardholder data by business need to know
8. Identify users and authenticate Erişim: system components
9. Restrict physical Erişim: cardholder data

**Regularly Monitor and Test Networks**
10. Log and monitor all Erişim: system components and cardholder data
11. Test security of systems and networks regularly

**Maintain an Information Security Policy**
12. Support information security with organizational policies and programs

### Key PCI DSS 4.0 Changes
- **Customized Approach**: Alternative to defined approach, allowing custom control design with objective-based validation
- **MFA for all CDE access**: Extended beyond admin to all Erişim: cardholder data (Req 8.4.2)
- **Targeted Risk Analysis**: Organizations perform their own risk analysis for flexible requirements
- **Authenticated Vulnerability Scanning**: Internal scans must use authenticated scanning (Req 11.3.1.1)
- **Anti-phishing mechanisms**: Technical controls to tespit etme
and protect against phishing (Req 5.4.1)
- **Automated log review**: Automated mechanisms for review of audit logs (Req 10.4.1.1)

## İş Akışı

### Aşama 1: Scoping and Assessment (Weeks 1-4)
1. Identify all cardholder data flows (card present, card not present, storage)
2. Define Cardholder Data Environment (CDE) boundaries
3. Validate network segmentation effectiveness
4. Belirle: compliance validation level
5. Conduct PCI DSS gap assessment against all 12 requirements

### Aşama 2: Network and System Security (Weeks 5-12)
1. Dağıt: and configure network security controls (Req 1)
2. Implement network segmentation to minimize CDE scope
3. Harden system configurations using CIS Benchmarks (Req 2)
4. Implement WAF for public-facing web applications (Req 6.4.1)
5. Dağıt: anti-malware on all in-scope systems (Req 5)

### Aşama 3: Data Protection (Weeks 13-20)
1. Implement encryption for stored cardholder data (Req 3)
2. Dağıt: tokenization where possible to reduce scope
3. Enforce TLS 1.2+ for all cardholder data transmission (Req 4)
4. Implement key management procedures
5. Dağıt: data discovery tools to Bul: unencrypted cardholder data

### Aşama 4: Access Controls (Weeks 21-28)
1. Implement RBAC based on business need to know (Req 7)
2. Dağıt: MFA for all Erişim: CDE (Req 8)
3. Implement unique user IDs for all users
4. Enforce password policies meeting PCI DSS 4.0 requirements
5. Implement physical access controls for CDE facilities (Req 9)

### Aşama 5: Monitoring and Testing (Weeks 29-36)
1. Dağıt: centralized logging for all CDE components (Req 10)
2. Implement automated log review mechanisms
3. Conduct internal and external vulnerability scans (Req 11)
4. Perform penetration testing (internal and external)
5. Implement file integrity monitoring (FIM) for critical files

### Aşama 6: Policy and Governance (Weeks 37-42)
1. Develop comprehensive information security policy (Req 12)
2. Implement security awareness training including anti-phishing
3. Establish incident response plan specific to cardholder data
4. Conduct targeted risk analyses for flexible requirements
5. Document and validate all controls for assessment

## Key Artifacts
- CDE Scope Documentation and Network Diagrams
- Self-Assessment Questionnaire (SAQ) or Report on Compliance (ROC)
- Attestation of Compliance (AOC)
- Quarterly ASV Scan Reports
- Annual Penetration Test Report
- Risk Assessment Documentation
- Security Policies and Procedures

## Common Pitfalls
- Scope creep due to inadequate network segmentation
- Storing prohibited data (CVV, full track data) after authorization
- Missing the March 2025 deadline for new mandatory requirements
- Treating PCI DSS as annual compliance rather than continuous security
- Not including cloud and container environments in CDE scope
