Use a specific case such as observing project files copied from an approved folder to a USB device outside the allowlist. Every collected field should support an approved purpose.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_data_should_be_collected\"><\/span>What data should be collected?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Prefer the minimum metadata and context: endpoint, account, time, action type, file name\/type, source, destination, scale and matched rule. Original content, screenshots or deeper personal data require separate assessment, a clear purpose and stronger controls.<\/p>\n<ul>\n<li>Do not upload original files when metadata is sufficient.<\/li>\n<li>Mask or hash sensitive fields where practical.<\/li>\n<li>Avoid personal folders unless the approved use case requires them.<\/li>\n<li>Distinguish corporate devices from personally owned devices.<\/li>\n<li>Document which data leaves the endpoint and where it is stored.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_should_employee_notice_contain\"><\/span>What should employee notice contain?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Notice should be understandable and consistent with policy: protection purpose, observed devices and channels, event data, authorized roles, retention, investigation process and a contact for questions.
