4 ASSESSMENT TIER #2 – LIFECYCLE REQUIREMENTS 4.1 OBJECTIVE 4.1.1 The objective of this activity is to ensure that the developer adopts a “Security-by-Design” approach and implements adequate processes and practices to design, create, and maintain security in the Internet-Connected Device. 4.1.2 Assessment Tier 2 is based solely on declaration of conformance by the developer. 4.1.3 Devices that complete Assessment Tier 2 would entail that the developer has taken steps to identify the threats commonly associated with such devices and have implemented security measures against common threats for Tier 2. 4.2 REQUIREMENTS 4.2.1 Assessment Tier 2 references the lifecycle security considerations of the IMDA IoT Cyber Security Guide [2] published by the Info-communications Media Development Authority (IMDA). 4.2.2 The developer is required to fulfil all 9 lifecycle provisions (CK-LP-01 to CKLP-09) listed in Chapter 7 – Conformance Checklist of this document. 4.3 DECLARATION OF CONFORMANCE 4.3.1 For all device categories, the developer shall complete and submit the Conformance Checklist found in Chapter 7 – Checklist of this document to CCC to declare conformance to lifecycle requirements. 4.3.2 The developer shall provide adequate supporting evidences alongside the Conformance Checklist (e.g. detailed descriptions, screenshots, process charts, work instructions, etc.) such that CCC is able to assess if the requirements for Tier 2 have been met, and that the security lifecycle processes and practices are adopted. Some examples of the expected supporting evidences are listed in the checklist. 4.4 ACCEPTANCE CRITERIA 4.4.1 No independent testing nor an audit by the testing laboratory is required for Assessment Tier #2. 4.4.2 However, CCC will review the submitted Conformance Checklist and supporting evidences. Assessment Tier #2 is only considered satisfied when CCC gains assurance through the submitted supporting evidences that the developer has implemented the required processes and practices and utilises them throughout the lifecycle of the DUT.
