Compliance Hardening & Regulatory Alignment
Passing third-party security audits requires verifiable, documented technical controls. Khodshima Sumn Assist LTD configures, hardens, and certifies Linux server environments to satisfy PCI-DSS v4.0, GDPR / UK DPA, and ISO/IEC 27001:2022 standards.
This is to attest that the target Linux server infrastructure has been audited, fortified, and configured in accordance with the strict technical baselines of:
Three Core Compliance Standards Covered
We deploy concrete, verifiable technical controls mapped directly to auditor requirements:
PCI-DSS v4.0 Standard Hardening
Meets mandatory requirements for merchants processing cardholder data. We disable vendor default accounts, enforce cryptographic multi-factor SSH, configure NTP time sync, and activate immutable audit trails.
- ✓Requirement 2.2: Standardized system hardening baselines applied
- ✓Requirement 8.3: Strict cryptographic key authentication & lockout thresholds
- ✓Requirement 10.2: Synchronized NTP time sources & tamper-evident audit logs
- ✓Requirement 11.3: External & internal port vulnerability verification
GDPR & UK Data Protection Act
Aligns server technical architecture with Article 32 (Security of Processing). Enforces encryption-at-rest for databases and backup vaults, applies least-privilege permission masks, and deploys real-time breach detection.
- ✓Article 32: AES-256 encrypted database volumes and offsite backup vaults
- ✓Article 25: Least-privilege system UID/GID isolation per web pool
- ✓Article 33: Automated incident detection & real-time notification hooks
- ✓Article 5: Immutable data integrity verification against tampering
ISO/IEC 27001:2022 Governance
Implements concrete operating system controls required by Annex A. We establish version-controlled configuration baselines, automate patch management, and enforce strict network boundary segregation.
- ✓Control A.8.8: Technical vulnerability management & Lynis CIS scoring
- ✓Control A.8.9: Configuration management & documented hardening profiles
- ✓Control A.8.20: Network security & stateful NFTables packet isolation
- ✓Control A.8.24: Cryptographic key management & cipher suite governance

Explore the technical configurations implemented to satisfy specific regulatory requirements:
PCI-DSS v4.0 (Fintech & Payments)
Disable default accounts, remove insecure protocols (telnet/ftp/rlogin), and enforce single-primary function per system.
sysctl.conf hardened + NFTables default-drop + purge inetdEnforce cryptographic key-based SSH, multi-factor for administrative access, and PAM lockout thresholds after 3 failures.
