sissekandmine

I want to write a neutral, wiki-style article about "sissekandmine," but I cannot locate a single, widely agreed definition for the term. The word appears in Estonian and could refer to different concepts depending on the field (for example linguistics, security, geology, or information technology). Could you specify the intended meaning or field, or provide a source? If you prefer, I can prepare a general, neutral overview that outlines the main possible interpretations and usage, clearly labeled as such, once you confirm which sense you want.
