PCI DSS v4.0 Compliance for Network Infrastructure
PCI DSS v4.0 introduces significant changes to network security controls, including the new customized approach and updated requirements for network segmentation, firewall rules, and secure configurations. ConnectMyAssets automates the network-level controls in Requirements 1, 2, 10, and 11 that protect cardholder data environments.
Why PCI DSS v4.0 Changes Network Security
PCI DSS v4.0 replaced v3.2.1 on March 31, 2024, with future-dated requirements becoming mandatory by March 31, 2025. Network controls are foundational to cardholder data protection.
Requirement 1, Network Security Controls
Requirement 1 (formerly "Install and maintain a firewall") now mandates "network security controls" (NSCs), a broader term covering firewalls, cloud security groups, NDR, and SDN policies. All NSC rulesets must be reviewed every six months (1.2.7) and documented with business justification for every allow rule.
Requirement 2, Secure Configurations
Requirement 2 requires changing vendor-supplied defaults, removing unnecessary services, and configuring all system components securely. New sub-requirement 2.2.7 mandates encryption of all non-console administrative access. Configuration standards must be reviewed when new vulnerabilities are identified.
Requirement 10, Logging & Monitoring
Requirement 10 mandates logging all access to system components and cardholder data. New in v4.0: automated mechanisms to detect and alert on security event log failures (10.7.2) and review of all other log types at least once every 12 months (10.4.1.1).
Requirement 11, Security Testing
Requirement 11 requires regular security testing including internal and external vulnerability scans, penetration testing, and network intrusion detection. New in v4.0: internal vulnerability scans must be authenticated (11.3.1.2) and change detection mechanisms must run weekly on payment page scripts (11.6.1).
PCI DSS v4.0 Network Capabilities
Purpose-built features that map directly to PCI DSS v4.0 network security requirements.
NSC Ruleset Review & Documentation (1.2.7)
Automatically inventory all firewall and NSC rules, flag rules without business justification, identify overly permissive "any/any" rules, and track six-month review cycles. Generate Requirement 1.2.7 evidence showing ruleset review completion and rule-by-rule documentation.
Secure Configuration Baselines (2.2)
Define and enforce PCI DSS-compliant configuration standards for every network device class. Detect vendor defaults, unnecessary services, insecure protocols, and unencrypted admin access. Satisfy Requirement 2.2 with automated baseline compliance checks.
CDE Segmentation Validation (1.4)
Validate cardholder data environment (CDE) segmentation by analyzing firewall rules, ACLs, VLAN configurations, and routing tables. Verify that traffic between trusted and untrusted networks is properly controlled per Requirement 1.4 and detect segmentation leaks.
Configuration Change Logging (10.2)
Capture and log every network configuration change with user identification, timestamp, affected device, and diff comparison. Meet Requirement 10.2 audit log requirements with immutable, tamper-evident records that include before/after configuration states.
Network Vulnerability Assessment (11.3)
Identify known firmware vulnerabilities, insecure protocol configurations (SSLv3, TLS 1.0/1.1, SNMPv1/v2), and missing security patches across your network. Support Requirement 11.3 vulnerability scanning with authenticated configuration analysis.
QSA-Ready Compliance Reports
Generate pre-formatted evidence packages organized by PCI DSS v4.0 requirement number. Provide your QSA or ISA with structured documentation for Requirements 1, 2, 10, and 11 that maps directly to SAQ and ROC reporting templates.
Three Steps to PCI DSS v4.0 Network Compliance
Assess, Scope & Gap Analysis
Connect your in-scope network devices and run an automated PCI DSS v4.0 gap assessment. ConnectMyAssets identifies your CDE boundaries, validates segmentation controls, scans configurations against Requirements 1 and 2, and produces a prioritized remediation plan with estimated effort per finding.
Implement, Harden & Enforce Controls
Deploy PCI DSS-compliant configuration templates, enforce secure defaults, disable unnecessary services, and establish rule review workflows. Configure change logging per Requirement 10, implement NSC rule documentation per Requirement 1, and validate CDE segmentation.
Maintain, Continuous Validation & Audit Support
Automate quarterly internal scans, six-month NSC rule reviews, and continuous configuration drift detection. Generate evidence packages ahead of annual assessments. Track the status of future-dated v4.0 requirements to ensure readiness before enforcement deadlines.
