The purpose of these requirements is to help agencies:
- identify the protection requirements for official information
- establish protection requirements for official information.
The audience of these requirements is:
- New Zealand government employees
- New Zealand government contractors
- any person with access to official information that requires protection.
These requirements cover information security within the New Zealand government, recognising official information requires additional control measures.
These measures will assist agencies in identifying the value of information to better ensure its protection.
This protection is communicated through the application of a suitable protective marking.
The application of protective markings to Cabinet papers and foreign government information are also discussed in this document.
These requirements relate to information security within the New Zealand government.
They support the implementation of the New Zealand Protective Security Requirements (PSR) and, in particular, the Information Security Management Protocol.
These requirements are part of a suite of documents that assist agencies to meet their information security mandatory requirements.
Agencies must also take into account legal requirements under the:
1.4 Compliance requirements
A control with a ‘must’ or ‘must not’ compliance requirement indicates that use of the control is mandatory. These are the baseline controls unless the control is demonstrably not relevant to the respective agency and can be clearly demonstrated to the agency head or accreditation authority.
A control with a ‘should’ or ‘should not’ requirement indicates that use of the control is considered good and recommended practice. Valid reasons for not implementing a control could exist, including:
- a control is not relevant because the risk does not exist
- or a process or control(s) of equal strength has been substituted.
Agencies must recognise that not using a control without due consideration may increase residual risk for the agency. This residual risk needs to be agreed and acknowledged by the agency head. In particular an agency should pose the following questions:
- Is the agency willing to accept additional risk?
- Have any implications for All of Government security been considered?
- If so, what is the justification?
A formal auditable record of this consideration and decision is required as part of the governance and assurance processes within an agency.
The PSR provides agencies with mandatory and best practice security measures.
The controls detailed above identify if and when agencies need to consider specific security measures to comply with the mandatory requirements.
