  • Blue Waters is shared by many users and provides the standard file permission tools for users to protect their data from unauthorized access by other users and groups. It is the PI and his/her team's responsibility to set appropriate permissions or use any extra tools (e.g. encryption tools) to protect their data. It is possible to expose confidential data through misconfiguration of permissions by the user.
