Acauã: Network Detection & Threat Hunting, heuristic analysis over a rolling 7-day window using deterministic math (time series, graph theory, information theory) instead of opaque ML models. Third product in the Ciberfauna ecosystem, alongside Guará and Sabiá. Follows the ecosystem's established conventions: OpenWolf project memory, bilingual PT-BR/EN docs and UI, Gitea Actions CI/CD on the same self-hosted runners, Conventional Commits, SemVer, logo and productName handling, MIT OR Apache-2.0 licensing. Architecture decision (made with the project owner after a dedicated consultation, not the original blueprint's suggested stack): Rust throughout, not Python/FastAPI/React. Most of the statistics (Bowley skew, MADM, Shannon entropy, PCR, Z-score, novel-edge detection, pivot chains) reduces to SQL over an embedded DuckDB/Parquet store; only the spectral analysis and graph centrality need host-language code, and both have workable Rust crates. Documented in full, including six corrections to the original blueprint's math (Rayleigh/Schuster instead of a degenerate Lomb-Scargle over bare timestamps, an explicit sentinel for Bowley skew's Q3=Q1 case, Jensen-Shannon instead of unbounded KL, a dedicated long-connection detector, JA4 vs. JA4+ licensing caution, deterministic per-alert evidence), in docs/architecture.md. Skeleton only: crates/acaua-core has the four detection pillars, fusion, storage, zeek log parsing and the updater as typed stubs that compile and return a clear "skeleton" status rather than real detection logic — that is separate, future work. crates/acaua-cli has serve/analyze/doctor/update. apps/gui is a minimal Tauri shell. Also already includes the one-click desktop self-update mechanism shared with Guará and Sabiá (AppImage/.deb/Windows installer), even with no release published yet, for consistency across the ecosystem. No Gitea repository exists for this project yet; this is a local-only commit.

The image is for lab and research use. It runs the same acaua binary as a
native install, with the embedded UI. The skeleton does not enable the DuckDB
feature in the image; the store remains reserved for a later release.
Build
docker build -t acaua .
docker run --rm -p 127.0.0.1:8787:8787 -v "$PWD/data/acaua:/data/acaua" acaua
The build stage uses rust:1-slim-bookworm; the runtime stage uses
debian:bookworm-slim and installs only ca-certificates, curl and tar
(the updater needs curl and tar).
Compose
cp .env.example .env # optional: set ZEEK_INTERFACE
docker compose up --build
The Compose file starts two services:
| Service | Purpose | Notes |
|---|---|---|
zeek |
Capture and write Zeek logs to ./data/zeek |
Host network and NET_RAW/NET_ADMIN |
acaua |
Read logs and serve the UI/API | Host port bound to 127.0.0.1:8787 |
acaua mounts ./data/zeek read-only at /data/zeek and ./data/acaua
read-write at /data/acaua. The daemon inside the container binds
0.0.0.0:8787, but the published port is loopback-only on the host.
Data layout
data/
zeek/ # Zeek logs, written by the zeek service
acaua/ # store, exports and runtime files
Do not mount the host root or a directory containing unrelated sensitive files. The parser is expected to confine paths to the dataset root; the skeleton does not parse records yet.
Security notes
- The
zeekservice needs packet capture privileges. Run it only on an interface and network you are authorized to monitor. - Do not change the host port mapping to
0.0.0.0:8787without an authenticating reverse proxy. - The image has no telemetry and no outbound connection except an explicit
acaua update. - The container is not a sandbox for hostile datasets. Treat a malformed capture as hostile input and keep the container unprivileged.
Limitations
- No DuckDB build in the image; the analytical store is not active.
- The UI is a shell and
analyzereturns a stub report. - The image does not include Zeek; the Compose file uses the upstream Zeek image.
- There is no published image registry yet. Build locally.
