Framework - ISO 27001 (Cyber)

A.5.13 builds on classification by requiring that information be labelled according to handling requirements. For the exam, understand that labels may be visual (document headers/footers, watermarks), metadata (embedded tags), or technical (container tags in data platforms). Correct labelling ensures that downstream controls—encryption policies, sharing restrictions, retention rules—can act automatically. A.5.14 governs information transfer in all forms, including email, APIs, file exchanges, and physical media, requiring security controls commensurate with classification and risk. This control emphasizes defined procedures, authorization, and logging to preserve confidentiality and integrity in transit, whether inside the enterprise or across organizational boundaries.

Implementation uses integrated labelling solutions that apply tags at creation, inheritance, or detection, with users guided by simple choices and defaults driven by context. Labels trigger conditional access, rights management, and DLP policies to prevent oversharing and exfiltration. Transfer protections include TLS for services, secure file gateways, key exchange procedures, and data processing agreements for third parties. Pitfalls include manual labelling that users ignore, inconsistent tags across tools, and ad hoc file sharing via unapproved channels. Robust programs measure label coverage, false positives/negatives in auto-labelling, and transfer exceptions with business justifications. Candidates should be prepared to describe artifacts such as approved transfer methods by data class, API security patterns (authentication, authorization, rate limits), and cross-border transfer assessments that document legal safeguards.
