BYOD and ISO 27001

Answer:

First of all, you have to perform a risk assessment to identify which risks related to BYOD practice you have to treat, and which legal requirements (e.g. clauses of contracts, laws or regulations) you have to fulfill. After that you have to identify proper controls to be implemented. In general, to secure BYOD practices you have to consider the following controls:
- A.6.2.1 Mobile device policy
- A.6.2.2 Teleworking
- A.13.2.1 Information transfer policies and procedures
- A.13.2.3 Electronic messaging

Normally these are implemented through a BYOD policy, which you can see how it looks like at this link: https://advisera.com/27001academy/documentation/bring-your-own-device-byod-policy/
