What are the two classifications of Prevalence regarding binary hashes?

The classification of Prevalence regarding binary hashes is effectively understood through the terms Local and Global.

In this context, "Local" prevalence refers to the occurrence of a specific binary hash within a specific environment or organization. This means it can be used to identify files or executables that are common to that particular system or network.

On the other hand, "Global" prevalence refers to how often the binary hash appears across a broader spectrum, such as on the internet or among various organizations globally. This classification provides insight into how widespread a particular file or executable is across different systems.

Understanding these two classifications helps security professionals determine the significance of specific hashes, guiding responses to potential threats. By assessing whether a hash is local or global, responders can tailor their investigation and remediation efforts based on the prevalence and context of the file in question.
