Initial considerations

💽 Establish a resilient backup strategy and back up your data.

• Should unauthorized modifications take place, it is important that you have a “clean” (unaffected) backup to revert back to.

🔢 Compute and check checksums on your integral data files.

• Hashing algorithms provide a unique output sequence for every unique input. This means that even if a single bit of a file has been altered, a radically different output sequence will be produced, even if the input file might initially appear unmodified.
