Actors from the regalian world or those specialised in Defence and Security are brought to scan the digital environment in order to identify elements of risk potentially threatening the security of people, places and organisations.

To do this, many sensors, information sources and types of information that are more or less available, open and structured are used in order to carry out the most secure, reliable and detailed surveillance possible. There is a whole specific lexicon inherent to this sector with numerous acronyms that are often complex to understand for neophytes, which this glossary aims to decipher and simplify for your understanding.

We propose to review the following main acronyms by dissecting their meaning, knowing that they all use the same methodology based on various and varied sources of information and relying on the same process, i.e. the collection of data with a view to analysing and processing them to clarify a more or less strategic decision.
