Identity and access management

Join, move, leave. Who you are, how you prove it, what you may do, and how that ends when the job does.

IAM / join, move, leaveIdentifywho is thisAuthenticateprove itAuthorisewhat nowLifecycle is the hard part. Orphaned accounts outlive projects.

IAM is how an organisation grants or refuses authorisation to systems. Unique identities, authentication, roles, joiner-mover-leaver, privileged access, and logs of who proved what.

Most incidents still start with a stolen or over-privileged identity. Service accounts and OAuth grants are identities too. They outlive the project that created them unless someone owns the inventory.

Build the process before you buy another dashboard. A tool cannot join and leave people you have not listed.
