Part of the Network security glossary:

An object identifier (OID) is an unambiguous, long-term name for any type of object or entity

The OID mechanism finds application in diverse scenarios, particularly in security, and is endorsed by the International Telecommunication Union (ITU), the Internet Engineering Task Force (IETF), and ISO.

In computing, an OID appears as a group of characters that allows a server or end user to retrieve an object without needing to know the physical location of the data. This approach is useful for automating and streamlining data storage in cloud computing environments. On the Internet, an OID takes the form of a Universal Unique Identifier (UUID), a 128-bit number used to uniquely identify an object or entity. In a database, an OID is a set of integers that uniquely identifies each row (or record) in a table.
