Documentation Guidelines

"Remember kids, the only difference between Science and screwing around is writing it down"

Screenshots

Redaction

  • Sensitive information should be redacted from screenshots used in documentation (unless you are very sure of the security controls in place to restrict access).

  • You should cut the information rather than just masking it.

  • If you must mask use solid blocks of colour, don't blur.

  • Use a lossless format like png rather than a lossy format like jpeg (jpeg compression artifacts can give enough clues to allow the redacted information to be identified).

  • If you use tools like Photoshop of GIMP to redact, be aware that the information may continue to exist in another layer. Export the redacted image to a flat (non-layered) file format (e.g . png) and securely delete any copies saved in layered formats.
