Data protection for Amazon Managed Blockchain (AMB) Access Ethereum

Data encryption helps prevent unauthorized users from reading data from a blockchain network and the associated data storage systems. This includes data that might be intercepted as it travels the network, known as data in transit.

Encryption in transit

By default, AMB Access uses an HTTPS/TLS connection to encrypt all the data that's transmitted from a client computer that runs the AWS CLI to AWS service endpoints.

You don't need to do anything to enable the use of HTTPS/TLS. It's always enabled unless you explicitly disable it for an individual AWS CLI command by using the --no-verify-ssl command line option.
