The ultimate objective of OPSEC is to prevent sensitive (referred to in this article as confidential), information from falling into the hands of an adversary, primarily by denying them from uncovering and gaining unauthorised access to your data. One of the most important steps in conducting OPSEC is the analysis of the potential risks to the data you are trying to prevent the adversary from obtaining/seeing. Understanding how an attacker may gain an insight into your movements or access to data they can later use against you is vital in ensuring that the correct countermeasures are deployed.
