When handling hypersensitive information, it is essential to share your files in a secure manner. Make sure you only share your data with those who require it. This will minimize the possibility that a significant portion of your data is lost to wrong hands in the event of a breach or leak. Make sure that you have devices that block unauthorised edits of files. You can use programs to encode files if you're working with a colleague on an Excel spreadsheet. This protects the document from enhancing system resilience with cloud redundancies malicious or accidental changes and ensures that the numbers are accurate.
The addition of a watermark to your files is an excellent idea. It provides an additional layer of security and allows you to monitor who is using your files. You can also put an expiration date on download links, and then deactivate access to the file after a specified amount of time. This will stop hackers or even employees who have no authority from keeping personal information for longer than they are permitted to do so by company guidelines. Create a guideline to instruct your staff in how to destroy a document many times.
It doesn't matter if it's research data, student information, or your carefully-crafted spreadsheets and documents, the information you store on your devices is incredibly valuable. One wrong move, and sensitive data could be thrown out to anyone to exploit, causing financial damages or damage to your reputation.
