This sample illustrates the general considerations an organisation needs
to undertake in respect of creating the comprehensive archive to which
the Codel Audit Trail Protection protocols will add their "assurance
layer". Many organisations will already have comprehensive archiving
in place and robust security around the storage. They will have least
to do to implement the protocols.
The policy should begin by stating the formalities...

the following day (for the period just completed).
