A useful concept that emerged in my security incident response research is a one of THREE IR GAPS.
- Detection gap
- Triage gap
- Remediation gap
Here is what I mean:
|Stage before||Gap||Gap length||Stage after|
|“Everything is fine!”||Detection gap||Days to years
|“Oh no, this looks like an incident!”|
|We are having an incident||Triage gap||Hours to weeks||We know the full scope of this one and we know how they got in|
|Investigation mostly complete, ready to fix it||Remediation gap||Days to weeks||Incident remediated – next?|
