Start with a practical map rather than a product list. Identify the accounts, devices, information, people, services, vendors, and physical contexts that support the work. Note who needs access, what would happen if access or integrity were lost, what information is sensitive, and which services or people are dependencies.

Useful categories include identity and authentication, business and personal information, customer or employee records, devices, email and messaging, cloud storage, payment or scheduling services, backups, vendors, and recovery contacts. The goal is a shared picture of priorities and decisions, not a perfect inventory.

Social engineering often combines authority, urgency, secrecy, process bypass, an unexpected attachment or link, a request for credentials or payment, or a change to normal instructions. A familiar name, logo, phone number, or writing style can be copied or compromised, so verify through a trusted channel instead of replying to the suspicious request.

Useful measures answer a decision question. Examples include the percentage of important accounts using approved second factors, supported devices receiving updates, backups completing and being tested, stale access being removed, reports reaching the right owner, time to acknowledge suspicious activity, repeat incident patterns, and completion of assigned improvements.

Measure carefully. A high report count can mean awareness or an attack wave; a low report count can mean safety or silence. Pair counts with context, quality, response, recurrence, and evidence that the control works.
