I would appreciate your assistance in understanding the security features offered by Bitbucket from an information security perspective. Currently, I am using same for code repository management, but it does not provide sufficient security for my application code. I would like to know if it can be securely hosted on a cloud environment like AWS, ensuring proper access controls and data protection. Could you please provide clarity on Bitbucket security features and how they align with best practices for securing application code in the cloud?
