Control 4.2Understanding the needs and expectations of interested parties
Identify the parties relevant to the information security management system, and determine which of their requirements the system has to meet — including legal and regulatory requirements and contractual obligations.
“Interested parties” is broader than customers. It includes regulators and supervisory authorities, employees, shareholders, suppliers and the organisations that depend on you, and each carries requirements of a different kind: a supervisor imposes obligations, a customer imposes contract terms, an employee imposes expectations that shape whether a control is followed in practice.
The clause asks for a decision, not a list: which of these requirements will be addressed through the ISMS. That is the part most often skipped. A register of interested parties with no statement of which requirements are in and which are handled elsewhere leaves the scope in 4.3 resting on nothing, and leaves an auditor to conclude that the obligations were catalogued rather than accepted.
How to put this in place
Customers, regulators, staff and suppliers all expect things of your ISMS, and unrecorded expectations become surprises at audit. Interested parties may also have climate-related requirements, which is worth noting.
- Identify the interested parties that matter to information security.
- Record what each needs or expects, including contract terms, laws and any climate-related requirements they have.
- Decide which of these the ISMS will address, and link each to a control or process.
- Give the register to the legal and contract owners so changes reach it.
- Review it at least yearly and feed changes into the management review.
Evidence an auditor usually looks for: a register of interested parties and their requirements, linked to the scope, the register of legal requirements and the management review.
