At work, we are planning to take down a database for 24 hours. We are not going down the track of creating a "Hot standby", the DB will be completely offline throughout. During the downtime, we would like limited access to some information from the DB. Management wants to extract this limited set of information and store it temporarily in an excel file. We have been asked to implement security around this. Can you provide some suggestions on how can we achieve the following during the downtime?
- Avoid unauthorized access to the file containing the information.
- Protect the Confidentiality and Integrity of the data.
- Audit users accessing the file and the data.
- Avoid copying or exporting the file.
