Which technical or non-technical means should the customer provide themselves or consider providing themselves?
The user only needs to configure the network normally according to equipment operation manual, without installing additional software or hardware supporting equipment, such as firewall.
How is each of the technical and non-technical means expected to affect cybersecurity risk?

For example, proper implementation of data protection may help mitigate confidentiality risks, but may also reduce availability (e.g., if data cannot be decrypted or is decrypted slowly), which could increase availability risks.

Technical means such as cryptographic algorithms/ authentication mechanisms are used to protect data confidentiality and authorization. These technical means are able to prevent most common cybersecurity attacks.

Non-technical means such as security response centre, JIMI maintaining services are used to keep availability of device.
