    CVD requirements under RED Delegated Act, EN 303 645, and EN 18031 for CE and CRA cybersecurity compliance

    Operational Description Based on RED Delegated Act | CE & EN 303 645 Cybersecurity Compliance

    September 2, 2025
    Cyber Certification

    An Operational Description based on the RED Delegated Act, EN 303 645, and EN 18031 is a cornerstone of CE and cybersecurity compliance, detailing how your connected product functions — including its software, hardware, connectivity, and security mechanisms.

    At 360Compliance, we create documentation aligned with the Radio Equipment Directive (RED) Delegated Act, ETSI EN 303 645, and EN 18031, ensuring your product is audit-ready, secure, and globally marketable.

    What Is an Operational Description for CE & RED Compliance?

    An Operational Description explains the internal and external workings of a device or system. It is a key part of your technical documentation for CE and RED cybersecurity conformity.

    It typically includes:

    • Functional architecture: components, modules, and communication flows
    • Interfaces & network topology: how your device connects to others or to the cloud
    • Security controls in practice: authentication, encryption, and update mechanisms
    • Operational modes: normal, maintenance, and failure states

    👉 Refer to the Radio Equipment Directive (RED) Delegated Act on EUR-Lex for the official framework.

    Key Components of a Compliance-Ready Operational Description

    A strong operational description should include:

    • Device overview (OS, firmware, chipset)
    • Data flows and protection measures
    • Interface descriptions (USB, Wi-Fi, BLE, etc.)
    • Cryptography and key management
    • Update and patch processes
    • Vulnerability disclosure and incident handling
    • Power-up, boot, and safe mode behavior
    • Variant mapping for product families

    Why Operational Descriptions Based on the RED Delegated Act, EN 303 645 & EN 18031 Matter for CE Cybersecurity Compliance

    Operational Descriptions are crucial for compliance because they:

    • Demonstrate “security by design” as required by EN 303 645 and the Cyber Resilience Act (CRA)
    • Streamline CE/UKCA certification by pre-answering assessor questions
    • Support product family documentation under EN 18031
    • Build customer trust by proving your security design approach

    FAQs About CE Operational Descriptions

    Is an Operational Description mandatory?
    Not always explicitly required, but most Notified Bodies expect it for RED cybersecurity assessments.

    Does it replace test reports?
    No. It complements testing by documenting how the product is intended to function securely.

    Do variants need separate descriptions?
    Only when they differ significantly. Otherwise, reference a shared base document for product families.

    Cambodia-TRC
    Cambodia TRC Regulatory Updates
    March 21, 2024
    On December 11th, 2023, the head leader of Cambodia's Telecommunication Regulator of Cambodia (TRC) issued a notification to all officers regarding the review of type approval documents, emphasizing the importance of consistency between the information provided in test reports and that submitted by clients. This notification clarified that previously accepted practices, such as using the product name and country of origin as claimed by the client, should now align precisely with the details presented in the test report. Following discussions and confirmations, TRC officers reaffirmed on December 27th, 2023, that this new rule must be adhered to for all future projects seeking type approval. For submissions with one country of origin, the test report must indicate the CoO. In cases where a product has more than one country of origin, the report should display one CoO, with any additional CoOs declared in a separate declaration letter. Moreover, TRC explicitly stated that reports lacking any indication of country of origin will not be accepted under these new guidelines. This adjustment aims to enhance accuracy and consistency in reviewing type approval submissions. Streamlining TRC Type Approval with Support from 360Compliance 360Compliance specializes in navigating TRC's type approval process, ensuring documents precisely reflect the country of origin per the latest guidelines.

    SIRIM_MCMC_Certification
    Malaysia SIRIM-MCMC Regulatory Updates
    March 21, 2024
    The Malaysia SIRIM CMCS Department, responsible for MCMC certification, recently implemented a significant update regarding Intellectual Property (IP) Forms for Type Approval applications. These forms replace the trademark authorization letter to improve efficiency and accuracy in approvals. The new IP Forms categorize trademark declarations based on whether the applicant has obtained authorization from the trademark/brand owner. For applicants who have been authorized, the required documents include evidence of a registration certificate issued by the Intellectual Property Corporation of Malaysia (MyIPO). Or an equivalent foreign organization, along with an Intellectual Property (IP) Authorization Letter (eTAC/FOR/01-8). On the other hand, if the applicant has not obtained written consent and authorization to use the trademark/brand, they must submit the Intellectual Property (IP) Undertaking form issued by the applicant (eTAC/FOR/01-9). Importantly, these new forms are effective immediately and will be used for all new projects. They mark a significant shift in SIRIM's approach. The organization can now accept brands/trademarks that have not been officially authorized by the brand owner. However, in such cases, the importer must provide a written declaration accepting responsibility. Furthermore, the new Brand name authorization process requires both the Brand owner and the Importer to co-sign the Brand name authorization letter. This updated procedure aims to enhance transparency and accountability in the approval process for Type Approval applications, ultimately benefiting both applicants and consumers in Malaysia. Simplifying SIRIM Certification with 360Compliance Navigating the latest SIRIM and MCMC certification requirements can be complex, especially when introducing new Intellectual Property (IP) Forms. 360Compliance is here to simplify this process for you.

    India Regulatory Updates
    March 21, 2024
    India TEC issued a notification in January 2024 regarding generic exemptions for products without available test labs.  In January 2024, India's Telecommunications Engineering Centre (TEC) issued a significant notification regarding generic exemptions due to the absence of available test laboratories within the country. These exemptions represent a crucial development, indicating that specific parameters no longer require the submission of test reports if customers cannot provide them. It's important to note that while these exemptions are in place, ILAC reports for CE/FCC are still subject to regulations based on the specific product category. This means that evaluation criteria for these reports vary depending on the nature of the product. Furthermore, TEC has specified product categories that continue to accept ILAC reports. Notably, the validation for these exemptions has been extended until June 30, 2024, with the potential for further extensions based on the evolving circumstances. These updates underscore TEC's commitment to adapting regulations to facilitate market access while maintaining stringent quality standards in the telecommunications sector. TEC approves testing exemptions for several product categories under their mandatory testing and certification program The Telecommunications Engineering Centre (TEC), under the Ministry of Communications, recently issued a notification regarding the approval of test requirements exemptions for certain product categories that necessitate mandatory testing and certification. This development signifies a significant step towards streamlining regulatory processes and promoting efficiency in the telecommunications sector.
