Electronic Lab Notebooks (Electronic Laboratory Notebook or ELN) is the digital form of a paper lab notebook. In the pharmaceutical industry, it is used by researchers, scientists, and technicians to document observations, progress, and results from their experiments performed in a laboratory.

While ELN enables information to be documented and shared electronically, it also exposes proprietary information to malicious insiders or external hackers. As a result, ELN should be subject to appropriate security controls to prevent misuse or loss.
