ETSI EN 303 645 Requirements
35 recommendations and 33 security standards are included in the ETSI EN 303 645 standard for consumer IoT devices. Manufacturers may provide customers a safer and more secure consumer IoT environment by putting these recommendations into practice and ensuring that their products adhere to the relevant security requirements. We go further into a few of the ETSI EN 303 645 standards’ most common criteria.
No Universal Default Passwords
A key necessity for improving the cybersecurity of consumer IoT devices is the prohibition of universal default passwords. Default passwords provide a serious danger since they are often popular or well-known across several devices.
Hackers may swiftly access devices using default passwords, endangering user privacy and security. Some typical default passwords that should no longer be used due to security risks:
The privacy and security of users might be jeopardized when hackers obtain unauthorized access to devices with default passwords. Here are a few examples of default passwords that were formerly widely used but should no longer be used owing to security risks:
- “admin” or “admin123”: This is a common default password for many types of devices, including routers, network switches, and web-based interfaces.
- “password” or “123456”: These are frequently used as default passwords for various devices and online accounts, despite being easily guessable and weak.
- “guest” or “guest123”: Some consumer IoT devices, such as wireless access points or smart home devices, may have default passwords like “guest” to provide temporary access. However, these passwords should be changed immediately for security reasons.
- “admin1234” or “adminadmin”: These passwords are also used as default credentials for administrative access to devices and systems.
- “1234” or “0000”: Some simple devices, such as digital locks or keypads, may come with default passwords like these, which should be changed immediately to prevent unauthorized access.
These examples demonstrate the hazards of default passwords. However, manufacturers are becoming more cognizant of security risks and are eliminating default passwords or requiring strong passwords upon device setup.
Manufacturers must avoid default passwords on consumer IoT devices to conform with ETSI EN 303 645. Devices may have distinct pre-configured passwords.
Instead, users should be prompted to create strong passwords during setup. This rule ensures that each device has a user-specific password, making it harder for hackers to gain access. To comply with ETSI EN 303 645 criteria, users should be made aware of the security of passwords and default passwords should be avoided.
The emphasis should be placed on using a combination of capital and lowercase letters, numbers, and special characters. Manufacturers should offer clear instructions and recommendations on constructing secure passwords.
The length and intricacy of these combinations must also be taken into account. A key component of maintaining good security procedures is educating users about the necessity for frequent password upgrades.
Implement a System to Manage Vulnerability Reports
To make it easier to find and fix flaws, the ETSI EN 303 645 standard requires implementing a vulnerability disclosure procedure. This policy gives users, security researchers, and others a clear way to report any concerns they come across.
In order to develop a cooperative and proactive approach to security, manufacturers must also assure a prompt reaction, evaluation, and mitigation procedure for discovered susceptibilities.
Managing reports requires prompt reaction, evaluation, and remediation of reported risks. As soon as vulnerability reports are received, manufacturers should recognize them and start an evaluation to determine the severity and effect of the risks. Based on the possible dangers associated with the vulnerabilities, this evaluation allows manufacturers to set priorities and devote resources for fixing them.
Once these problems have been evaluated, manufacturers need to move right away to create and implement the necessary mitigation measures. To fix the found vulnerabilities, this can include publishing security patches or firmware upgrades.
Manufacturers should explain the remediation process to the appropriate parties, such as users, security researchers, and impacted parties, to keep them updated on the development and reassure them that their concerns are being taken seriously.
Maintain Software Updates
Manufacturers may guarantee that updates are safe from manipulation and unauthorized access by creating secure and authenticated ways for sending device updates. This reduces the possibility of malicious alterations or exploitation during the update process and assures the updates’ validity and integrity. Improving the general security posture of consumer IoT devices begins with educating people about the significance of upgrading their devices.
The process of upgrading the gadgets should be made simple and accessible by the manufacturers via the provision of clear instructions and recommendations. This makes updates more important to consumers and encourages them to quickly install firmware upgrades and security fixes.

Sensitive security parameters should be stored securely
Consumer IoT devices must secure important security parameters including encryption keys, according to ETSI EN 303 645. To accomplish this, manufacturers should use strong encryption techniques that prevent unwanted access or decryption.
Manufacturers should use secure storage techniques like hardware security modules (HSMs) or trusted execution environments (TEEs) on critical parameters.
These hardware solutions isolate sensitive data and cryptographic procedures from the device’s software and hardware, adding security. Manufacturers can protect encryption keys and other security settings against unauthorized extraction or manipulation using HSMs or TEEs.
Effective key management procedures improve the security of consumer IoT devices. Manufacturers should use cryptographically strong techniques to produce keys securely.
Key storage should be restricted to authorized persons and encrypted to prevent unauthorized disclosure.
Secure disposal of keys is equally essential to prevent potential security breaches. When keys are no longer needed, manufacturers must ensure they are effectively erased from memory or storage devices. Secure disposal techniques, such as cryptographic key wiping or physical destruction of storage media, can be employed to ensure that the keys cannot be recovered or used maliciously.
Secure Communication
ETSI EN 303 645 standards demand secure communication channels to protect sensitive data exchanged via networks in consumer IoT devices. It protects the confidentiality, integrity, and privacy of data sent between devices and other consumer IoT ecosystem organizations.
