FTA-005: Report Served From Stale Cache ¶
1 Status ¶
| Date | Status | |
|---|---|---|
| 06-07-2026 | Identified | |
| ▶ | 07-07-2026 | Analysed |
2 Top Event ¶
Misleading report delivered to the user (TOP-2)
3 Minimal Cut Set ¶
{E8} — report served from stale cache; a first-order cut set, one basic event suffices
4 Description ¶
The report engine serves cached figures that no longer match the underlying records, so the user acts on numbers that were true yesterday. Analysis is complete; the mitigation has not been designed yet, so the residual scores are still blank.
5 Severity ¶
6 Likelihood ¶
7 Mitigation ¶
Proposed: invalidate cached report data when the underlying records change and stamp every report with the time of its data snapshot.
8 Affected Documents ¶
| # | Proposed Text | Req-ID |
|---|---|---|

9 Monitoring ¶
To be defined together with the mitigation.
