ISO 27001 Controls Implementation

Organizational Controls (37 Controls)

Information Security Policies: Documented ISMS policy approved by board, reviewed annually. Policy covers: security objectives, risk management approach, compliance requirements, roles and responsibilities. Policy communication: all employees sign acknowledgment, quarterly security awareness training, policy accessible on internal wiki.

Risk Assessment: Annual enterprise risk assessment identifying: information assets, threats, vulnerabilities, risk levels. Risk treatment: accept, mitigate, transfer, or avoid. 2025 assessment: 42 risks identified, 38 mitigated, 4 accepted (low severity). Risk register maintained in Jira with quarterly reviews.

Asset Management: Information asset inventory covering: hardware (laptops, servers, network equipment), software (licenses, applications), data (client data, source code, financial records). Asset classification: Public, Internal, Confidential, Restricted. Asset owners assigned with accountability for protection.

People Controls (8 Controls)

Screening: Background checks for all hires: employment verification, education verification, criminal record check (where legally permitted), reference checks (3 professional references). Screening completion before access to confidential information. Screening results: 98% pass rate, 2% rejected due to discrepancies.

Security Awareness Training: Mandatory training for all employees: onboarding security training (4 hours), quarterly security awareness updates (1 hour), phishing simulation tests (monthly), incident response drills (annual). Training completion: 96% (2025), tracked in LMS. Training topics: password security, phishing recognition, data classification, incident reporting.

Disciplinary Process: Security violations result in: verbal warning (minor violations), written warning (repeat violations), suspension (serious violations), termination (critical violations). 2025 violations: 3 cases (2 verbal warnings for password sharing, 1 written warning for unauthorized data access). Zero terminations for security violations.

Physical Controls (14 Controls)

Physical Access Control: Office access via RFID badges, biometric fingerprint scanners for server room. Access logs maintained, reviewed monthly. Visitor management: sign-in required, escort mandatory, visitor badges issued. Server room access: restricted to 8 authorized personnel (VP Engineering, 4 DevOps engineers, 2 sysadmins, 1 security officer).

Equipment Security: Laptop encryption (BitLocker/FileVault) mandatory, remote wipe capability enabled, asset tags for tracking. Equipment disposal: hard drive destruction (physical shredding), certificate of destruction obtained. Lost/stolen equipment: 2 incidents (2025), both remotely wiped within 2 hours, zero data breaches.

Environmental Controls: Server room: temperature monitoring (18-24°C), humidity control (40-60%), fire suppression (FM-200 gas), UPS backup (30 minutes runtime), diesel generator (72-hour fuel capacity). Environmental incidents: 0 in 2023-2025.

Technological Controls (34 Controls)

Access Control: Multi-factor authentication (MFA) required for: VPN access, AWS console, production systems, source code repositories. MFA adoption: 100% for privileged accounts, 92% for standard accounts. Password policy: 12+ characters, complexity requirements, 90-day rotation, no password reuse (last 12 passwords).

Cryptography: Data encryption: at-rest (AES-256), in-transit (TLS 1.3), database encryption (transparent data encryption). Key management: AWS KMS for cloud keys, HSM for on-premise keys, key rotation every 90 days. Encryption coverage: 100% of client data, 100% of backups.

Network Security: Firewall rules (deny-all default, whitelist approach), intrusion detection (AWS GuardDuty), DDoS protection (AWS Shield), network segmentation (production/staging/development VPCs isolated). Security monitoring: 24/7 SOC, 15-minute P1 incident response SLA.

Vulnerability Management: Quarterly vulnerability scans (Qualys), annual penetration testing, continuous dependency scanning (Snyk). Vulnerability remediation SLA: Critical (24 hours), High (7 days), Medium (30 days), Low (90 days). 2025 performance: 98% SLA compliance.

Security Metrics & Performance

Incident Metrics: Security incidents (2025): 12 total (8 phishing attempts blocked, 3 unauthorized access attempts blocked, 1 malware detected and quarantined). Mean time to detect (MTTD): 8 minutes. Mean time to respond (MTTR): 42 minutes. Zero successful breaches (2023-2025).

Compliance Metrics: Control effectiveness: 98% (131 of 133 controls fully effective, 2 partially effective). Audit findings (2025): 0 major non-conformities, 2 minor non-conformities (both remediated within 30 days), 3 opportunities for improvement. Certification status: maintained continuously since 2021.

Training Metrics: Security awareness training completion: 96% (115 of 120 employees). Phishing simulation click rate: 4% (industry average 15%). Security incident reporting: 100% of incidents reported within SLA (24 hours).
