Abbreviated terms

Public text. This clause is public in the draft. The statement below is ours and the clause number is the citation; the official wording is the one to check against.

What it says, in our words

Five abbreviations are defined: DPO for data protection officer, IAM for identity and access management, LLM for large language model, MPC for multi-party computation and PII for personally identifiable information.

What it means for an ISMS manager

The list is short and each abbreviation points at a control area the document expects the reader to know. IAM signals that access control is part of the answer to big data risk. MPC signals that privacy-enhancing computation is in scope as a control option, not only as a vendor feature. PII and DPO signal that privacy is treated as a first-class half of the document, which the title also says. Use the list to check a supplier questionnaire. If a supplier answers a big data security question without naming who holds access, how identity is managed or where personal data is processed, the answer is thin against this vocabulary.

What an auditor samples

• The supplier questionnaire, with an IAM and a privacy section that use the same abbreviations.
• The access review record for the big data platform.
• The privacy impact assessment for any system that processes PII at scale.

Evidence lines are the artefacts an auditor or a reviewer asks to see. They are named here so the work can be planned; they are not a certificate and they do not replace the official text.
