    Topology Cybersecurity Compliance for IoT & ICT Devices – RED, EN 303645, EN 18031

    September 23, 2025
    Cyber Certification

    The network topology of connected devices is a key factor in cybersecurity and regulatory compliance. Poorly designed architectures can expose IoT, ICT, and radio equipment to cyber threats, data breaches, and compliance failures.

    At 360Compliance, we specialize in topology cybersecurity testing and risk assessment based on the RED Delegated Act (EU) 2022/30, CE EN 303645, and EN 18031. Our services ensure your connected devices meet EU and UK cybersecurity requirements for CE and UKCA certification.

    What Is Topology in Cybersecurity?

    In connected systems, topology describes how hardware, software, and network components are structured and communicate. A secure topology minimizes vulnerabilities, limits attack surfaces, and ensures safe, encrypted data transfer between devices, users, and cloud networks.

    Common topology vulnerabilities include:

    • Insecure device-to-device communication
    • Weak segmentation between critical and non-critical networks
    • Unencrypted or unverified data transfers
    • Lack of redundancy and failover mechanisms

    Regulatory frameworks such as the EU Cyber Resilience Act (CRA) and the RED Delegated Act (EU) 2022/30 now require manufacturers to demonstrate secure topology as part of product certification.

    Why Is Topology Security Important?

    A secure network and device topology ensures:

    • Protection of personal data in line with GDPR
    • Higher resilience against cyberattacks and unauthorized access
    • Regulatory compliance with EN 303645 and EN 18031 cybersecurity standards
    • Enhanced trust and reliability for IoT and ICT products

    Failure to design or validate a secure topology can lead to non-compliance, financial penalties, and delayed market access.

    RED Delegated Act, EN 303645, and EN 18031 — Why They Matter

    Secure topology is now a core part of CE and UKCA marking under European cybersecurity law:

    • RED Delegated Act – defines essential cybersecurity requirements for connected and radio devices.
    • EN 303 645 – sets the baseline for IoT device security, focusing on encryption, authentication, and architecture.
    • EN 18031 – provides guidance on ICT system resilience and cybersecurity assurance.

    Together, these standards ensure device topologies are secure, compliant, and certifiable under RED, CRA, and CE frameworks.

    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. Our team knows the latest SIRIM updates, including the new eTAC/FOR/01-8 and eTAC/FOR/01-9 forms. We provide comprehensive support, ensuring your Type Approval applications are complete, accurate, and compliant with the latest regulations.
