When dealing with information that is sensitive it is essential to share information in the most secure way. Only share information that they require. This will decrease the possibility of your data falling into the wrong hands in the event of a leak, or breach. Make sure you have a system that blocks unauthorised editing of files. There are programs that can encrypt files when you and a person are working together in an Excel spreadsheet. This will stop accidental or malicious changes and also ensure that the accuracy of numbers.
Another way to keep the data safe is to have a password, which acts as a gatekeeper to protect your information. It is also recommended to establish protocols to transfer files in a safe manner, such as Web communication protocols that work as police escorts for the data highway, helping different systems and devices communicate seamlessly across the Internet without getting bogged down by malware, viruses or other threats.
Watermarking can be used to protect sensitive information and best practices. It adds an extra layer of security and allows you to track who is using what. Additionally, you can place an expiration date on download links, and also remove access to a file after a specific duration of time, removing any incentive for hackers or even employees who are not authorized to keep personal information longer than it is needed. When you no longer require a file, write an instruction manual that instructs your staff on how to erase the file numerous times (like shredding the file with a digital device and degaussing), so that it’s not resurrected again in the future.
