Separately, ANY policy's OR ANY non-STATELESS (STATEFUL/STATEFUL_DOMAIN) rule group's `lastModified` after the range start taints attribution ACCOUNT-WIDE — stateless rule groups are excluded since they never carry `statefulSids` and their edits (far more frequent operationally) are irrelevant to this join (folded into `attributionUnsafe`, not scoped to the specific policy/group that was modified) — a rule group referenced by a policy earlier in the range and since removed from it (or deleted outright), or a rule group edited in place to drop a SID it used to carry, vanishes from (or changes in) every current-topology signal, so its historical hits merge by SID and can misattribute to an unrelated, unmodified rule group sharing that SID; this can't be enumerated locally, so the whole account is treated as unsafe instead (the same rule applies to policies and to rule groups themselves). A `lastModified` of `null` counts as "unknown", not "unmodified" — fail-closed, since a missing timestamp can't prove stability. Both range-start comparisons use `min(AnfwAnalysis.generatedAt, AnfwLogsAnalysis.generatedAt)`, not the browser clock and not either fetch's timestamp alone — the topology and log-Insights fetches are independent 4-minute-TTL caches, so using only one risks missing an edit that lands in the skew between them. A firewall switching which policy it uses mid-range, OR a firewall deleted outright mid-range, are both residual, undetected gaps — `AnfwFirewallRow` has no `lastModified` at all (unlike policies/rule groups, `DescribeFirewall` doesn't return one), and a deleted firewall's log group/hits still exist and still merge globally by SID even though the firewall itself has vanished from `resolveTargets`' current-inventory-driven target list, `alertCoverageComplete`, and every `lastModified`-based check above. Closing this would require correlating the already-fetched `?view=audit` CloudTrail stream for `DeleteFirewall`/`DisassociateFirewallPolicy` events in-range — a real follow-up, not implemented (no timestamp-based signal exists to fold into `attributionUnsafe` the way policy/rule-group edits are). Positive hits under `observability === 'unknown'` (some but not all serving firewalls confirmed logging) render as a `≥N` lower bound, same as the temporal-coverage and per-region-cap truncation cases, since the shown count may be missing matches from the unconfirmed firewalls. A region whose logging-config lookup is denied falls back to prefix-*discovery* (`AnfwLogTarget.discovered`); if discovery succeeds, that region's ALERT hits are NOT nulled and merge globally by SID same as any other region's — but that region's firewall/rule-group topology is unverifiable (the describe was denied), so a firewall/rule-group deleted there mid-range leaves no `lastModified` trace for any of the above checks to catch — so "any ALERT target is `discovered`" is folded into `attributionUnsafe` account-wide (the global SID merge applies to discovered regions too, not just enumerable ones) · `anfw-logs.ts` — Alert/Flow logs are aggregated via Insights only for CWL-destined groups (EVE JSON dot notation); when the logging-config lookup is denied, falls back to discovering the `/aws/network-firewall` prefix; `ruleHits: null` (query failed/chunk-truncated) is not the same as `[]` (queried successfully, zero hits) — callers must not collapse the two; the join cutoff (`ruleHitsTruncated`, top-100 sid) and the per-region overfetch cap (`ruleHitsPartial`, 150 rows/region — present sids can still be undercounted) are separate truncation signals, both must gate "confirmed idle" independently; `alertCoverageComplete` checks whether every used ALERT log group's `creationTime`/`retentionInDays` covers the range start — false collapses two distinct causes into one value ("coverage confirmed incomplete" vs. "coverage unverifiable" — group not found, missing `creationTime`, deadline hit, `DescribeLogGroups` denied) since both take the same conservative direction; it's an inference from log-group metadata, not proof that logging stayed continuously enabled on that group throughout the range · `sg-analysis.ts` — usage is ENI-Groups-attachment + SG-cross-reference (both 0 = unused); source/destination = SG reference → name · CIDR → VPC name · 0.0.0.0/0 → internet · prefix list → PL name; hit matching = Flow Logs (CWL, default-format parse, `dstaddr` ∈ own IP, inbound only — prevents misattributing outbound records). **(dstaddr, dstport, protocol) tuple match — not a rule-level "exact" figure**: if an ENI has multiple SGs or inbound rules overlap, traffic actually allowed by a different SG/rule can register as a hit on this rule (an overestimation bias — helps suppress false "idle" but the number itself must not be misread as precise rule attribution; caveat surfaced in the UI). The NFM fallback is **peer-identification only** (bidirectional byte aggregation can't attribute to a rule — `hits=null` suppresses false idle, across all 7 categories); rules referencing a prefix list/IPv6 CIDR/ICMP (type·code sit in FromPort/ToPort, making a dstport comparison meaningless) and SGs referenced outside the scanned range get `hits=n/a`; `?regions=` scans only the page's scope (per-scope detailCache separation); detailCache is build-then-swap (avoids an empty window during a rerun); `classifyEni` is reused from ip-inventory. diff --git a/web/lib/bounded-cache.test.ts b/web/lib/bounded-cache.test.ts index fc2129b9..f28b62b6 100644 --- a/web/lib/bounded-cache.test.ts +++ b/web/lib/bounded-cache.test.ts @@ -1,5 +1,5 @@ import { describe, expect, it, vi } from 'vitest';
