Identification

Identification is the foundational cybersecurity process of uniquely asserting the identity of an entity — whether a user, device, application, or system — within a digital environment. It serves as the critical first step in the access control chain, preceding authentication (verifying the claimed identity) and authorization (granting appropriate permissions). By establishing who or what is requesting access to resources, organizations can accurately assess potential threats, evaluate vulnerabilities, and implement targeted preventative measures to protect data confidentiality, integrity, and availability.

Beyond individual entities, identification also encompasses the broader practice of pinpointing critical assets, potential attack vectors, and known threat actors within a risk management framework. This holistic approach provides the intelligence needed to develop targeted defenses, understand adversary capabilities, and mitigate systemic risks. Common examples of identification include usernames, employee IDs, device certificates, and API keys. Strong identification practices underpin the entire security framework, serving as the bedrock upon which all subsequent layers of protection are built to safeguard information systems from unauthorized access and malicious activity.
