The ISO/IEC 27001 Framework is the internationally recognized standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It provides a systematic approach to managing sensitive information through risk management, governance, and control implementation. At its core, ISO 27001 helps organizations protect the confidentiality, integrity, and availability of data—whether stored, processed, or transmitted—by aligning security practices with business objectives and regulatory requirements. The framework is built around a risk-based process, requiring organizations to identify potential threats, assess their likelihood and impact, and implement appropriate controls from the companion standard ISO/IEC 27002. These controls cover a wide range of areas including asset management, access control, cryptography, operations security, and supplier relationships. By tailoring these controls to organizational needs, ISO 27001 supports both flexibility and accountability—ensuring that security measures are not just technical but also strategic and operational. Beyond compliance, ISO 27001 fosters a culture of continuous improvement through regular audits, performance monitoring, and leadership involvement. Certification to the standard demonstrates to customers, partners, and regulators that an organization follows internationally accepted best practices for managing information security risk. More than a checklist, ISO 27001 functions as an ongoing management framework that integrates security into every level of organizational decision-making, helping build trust, resilience, and long-term operational stability.

Episode 53 — A.7.13–7.14 — Equipment maintenance; Secure disposal/re-use

A.7.13 mandates that equipment be maintained correctly to ensure availability, integrity, and safety, with maintenance scheduled, authorized, and recorded. For exam preparation, distinguish preventive maintenance (vendor-recommended service intervals, firmware updates, filter replacements) from corrective maintenance after faults, and remember access controls for maintainers—identity verification, escorting, and least privilege on consoles. Maintenance windows should be risk-assessed, include backout plans, and protect data through backups and change documentation. Candidates should connect maintenance to configuration management: changes to firmware or components must update inventories and baselines so that security monitoring remains accurate, and logs should reflect who performed what, when, and with which parts or images.

A.7.14 governs secure disposal and re-use of equipment and media, ensuring that residual data and configurations cannot be recovered or misused. Approved sanitization methods—cryptographic erase for self-encrypting drives, multi-pass overwrite where applicable, or physical destruction—must be selected based on media type and data classification. Organizations should sanitize before repair, return, sale, or redeployment, and maintain certificates of destruction or erasure reports as evidence. Pitfalls include relying on factory resets that leave data, skipping sanitization for “non-storage” devices with hidden memory (printers, network gear, IoT), and outsourcing disposal without auditing the provider’s process. Mature programs tag assets with disposition states, require dual-person verification for destruction, and random-sample devices post-sanitization. Candidates should be prepared to describe end-to-end lifecycle controls—from maintenance benches with access restrictions to disposal vaults—and how records prove that operational efficiency never overrides the obligation to render sensitive data irretrievable.
