What changes afterwards, and what should
What changes afterwards, and what should. What it costs, who decides, and what usually goes wrong.

The review
Blameless, and within a fortnight
While people remember, and before the account has settled into a story. The purpose is to find what made the event possible and what delayed the response, not to identify who clicked.
Where the review produces a person rather than a process, it has usually stopped early. The person clicked because the message was convincing, or transferred the file because the compliant route was slower, and those are the findings that can be acted on.
What usually changes
Process more often than technology
The recurring outcomes are unglamorous: the contact list was wrong, the decision-maker was unreachable, logs from one system were not retained, nobody had the certificate, the machine was reimaged before anybody thought about evidence.
Each is fixed with an afternoon and none is fixed by a purchase, which is worth stating on a vendor's website.
Feeding it back
The incident is evidence
The standard requires an incident response capability, and an assessor may ask how you know yours works. A documented incident, with a timeline, a decision record, a report and a review, is the strongest possible answer.
Which means the paperwork produced during a bad week has value afterwards, provided it was kept.
The incident response family of the NIST publication, which requires an operational capability including preparation, detection, analysis, containment, recovery and user response activities, and testing of it.
How a given organisation demonstrates that capability is a matter for it and its assessor.
Over-correction
The control that makes work impossible
The strongest impulse after an incident is to prevent that exact thing forever, and the resulting control is frequently disproportionate: a route blocked entirely with nothing put in its place.
Within a month somebody has found another way and the organisation is worse off than before, because the new way is undocumented. The entry on the operator's view sets out the alternative.
Telling the board
Once, properly
What happened, what it cost, what has changed, and what remains open with a date. One page, at the next meeting, not a standing item that runs for six months.
A standing item invites monthly reassurance-seeking and prevents the matter being closed, which is bad for the programme and for the person running it.
What to keep
The file
The timeline, the decision record, the report submitted, the correspondence with the customer, the forensic output, the review and the actions with their completion dates.
Retained for the period the clause requires at minimum, and in practice longer, because the questions arrive later than the retention period assumes.
The last point
Most incidents are not attacks
Across this sector the majority of reportable events involve error, misdirection and loss rather than a sophisticated intrusion. That is not a reason to relax; it is a reason to put effort where the events actually are, which is in ordinary processes used by ordinary people under time pressure.
Which is where most of this blog has been pointing.
