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 66 — A.8.25–8.26 — Secure development lifecycle; Application security requirements

A.8.25 requires a secure development lifecycle (SDLC) that embeds security from concept to retirement, not as a late-stage gate. For the exam, describe SDLC phases with explicit security tasks: threat modeling during design; security requirements and acceptance criteria before coding; secure build pipelines with dependency hygiene; code reviews and static analysis during implementation; dynamic testing and abuse-case validation in verification; and hardening, logging, and rollback plans for release. Governance must define roles, entry/exit criteria, and evidence artifacts that demonstrate consistency across teams and technologies. The objective is repeatable assurance—each change carries traceable security rationale—so that risk management is visible to auditors and actionable by engineers. Candidates should be prepared to explain how SDLC controls support PDCA, turning lessons from incidents and tests into updated standards and training.

A.8.26 complements SDLC by mandating clear application security requirements that are risk- and context-driven. Requirements translate policy and threat intelligence into concrete behaviors: authentication strength, authorization models, input validation, output encoding, cryptography, logging fields, privacy-by-design constraints, performance under attack, and service-level expectations for vulnerability remediation. In practice, teams maintain a security nonfunctional requirements catalog mapped to data classifications and architectural patterns (web APIs, event-driven services, mobile apps), plus checklists for common frameworks so developers do not reinvent controls. Pitfalls include vague requirements (“be secure”), frozen checklists that ignore new attack modes, and exceptions granted without expiry or compensating tests. Effective programs version requirements as code in templates and linters, enforce them in CI with policy-as-code, and measure conformance via build breakers and release dashboards. Candidates should connect these controls to evidence—threat models, requirement traceability matrices, test results, and sign-offs—that collectively prove security intent became implemented, verified behavior.
