Bulk mover in a notice period
- High-impact
- Hard
- Data handling
- Level 2 · Cohort
People in a notice period or a role change who downloaded data in bulk above their own baseline.
Classification
- Risk domain One of 9 areas of human risk, from social engineering to readiness and response. Every signal belongs to one.
- Cohort class
-
- High-impact
- Difficulty
-
- Hard
A cohort is Easy when every one of its signals is available from standard connectors, Medium when any signal needs setup and none needs an integration or a survey, and Hard when any signal needs an integration or a survey.
- Dimensions Every signal answers one of 3 questions.
- Evidence level
- Maturity practices One capability a program performs, scored on its own: See, Understand, Act, Prove, Govern and Culture.
- Leads to The kind of breach the evidence beneath it points toward, each anchored to a Verizon DBIR or VERIS pattern or an FBI IC3 category.
- NIST CSF 2.0 (from its signals)
-
- DE.CM-03
- GV.RR-04
- MITRE ATT&CK (from its signals)
-
- T1530
The definition, in detail
Definition
Departure plus unusual volume is the classic insider pattern, and it is visible weeks before the last day.
Example
A sales director who resigned on the first of the month exported the full opportunity list twice in the following week.
How it is measured
- Formula
- DH-B-01 + DH-A-02
- Class
- High-impact
- Difficulty
- Hard: at least one signal needs an integration or a survey
- Risk domain
- Data handling
- Sources
- Web, CASB & DLP, HR system
How it is used
Programs count the people who match DH-B-01 + DH-A-02 at once as a high-impact cohort in Data handling, trend that population, and point the response at it; it feeds 1 breach scenario.
Membership is evidence that the signals in the formula describe the same person at once. It is a population to act on; on its own it confirms no incident.
