A transport layer security (TLS/SSL) feature for the communication between the server and device has been implemented in BioStar 2.4.
This feature would stop malicious users from connecting to the device by pretending to be the server with the same server IP.
This security option is achieved by storing a digital certificate in the device.
When the device connects to the server, it will exchange an encryption key (session key) using the digital certificate to provide server identity verification.
Follow the steps below to configure the secure communication. It is not turned on by default.
1. Log in to BioStar 2.
2. Click Setting.
3. Click Server.
4. On the Secure Communication with Device tab, set Secure communication with device as Use
If you want to use an external certificate from a CA (certificate authority) such as VeriSign, Comodo, GoDaddy and etc., check Use external certificates and Upload the file.
