A training carries a title, a description, an owner role and a duration in minutes. Its content is a YouTube or Vimeo video played inline, an external link that opens your LMS or a vendor’s portal in a new tab, or a PDF you upload, served through a time-limited download link rather than a public URL.
The owner is a business role, the security team, HR or the CISO, never a named individual. People come and go from roles, and the accountability stays put.
