It’s important that you protect your data when dealing with hypersensitive information. Make sure you only share the information to those who need it. This will lessen the risk that a significant portion your data will fall into unintentional hands in the event of a leak or breach. Use devices that prevent any unauthorised modifications to files. There are programs that protect files from being encrypted when you and another person are working in an Excel spreadsheet, for example, which protects against accidental or malicious modifications as well as ensures numbers remain precise.
Affixing a watermark on your files is an excellent idea. It adds an additional layer of security, and allows you to keep track of who has access to your files. You can include an expiration date to download links, and then remove access after a set period. This will stop hackers or even employees who have no authority to keep personal information longer than they are permitted to do so by the company’s policies. If you no longer need the file, create an instruction manual that instructs your employees on how to overwrite it several times (like shredding the document digitally and degaussing) to ensure it’s not able to be resurrected in the future.
It doesn’t matter if it’s research data, student information, or carefully designed spreadsheets and documents, the sensitive data stored on your devices is incredibly valuable. One wrong move, and sensitive data could be released in the wild for anyone to snoop on, causing financial damage or loss to your reputation.
