Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):
- brain/ LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
dispatch, A51 channels, and the OSINT cluster
- knowledge/ LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
MITRE ATT&CK data
- reference/ defensive threat-reference (C3, shhbruh doc) + AdaYaml parser
License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.
Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

|
|
description: Build an append-only log integrity chain using SHA-256 hash chaining for tamper detection. Each log entry is
|
|
hashed with the previous entry's hash to create a blockchain-like structure where modifying any entry invalidates all subsequent
|
|
hashes. Implements log ingestion, chain verification, tamper detection with pinpoint identification, and periodic checkpoint
|
|
anchoring to external timestamping services.

# Implementing Log Integrity with Blockchain
|
|
|
|
|
|
## When to Use
|
|
|
|
- When deploying or configuring implementing log integrity with blockchain capabilities in your environment
|
|
- When establishing security controls aligned to compliance requirements
|
|
- When building or improving security architecture for this domain
|
|
- When conducting security assessments that require this implementation
|
|
|
|
## Prerequisites
|
|
|
|
- Familiarity with security operations concepts and tools
|
|
- Access to a test or lab environment for safe execution
|
|
- Python 3.8+ with required dependencies installed
|
|
- Appropriate authorization for any testing activities
|
|
|
|
## Instructions
|
|
|
|
1. Install dependencies: `pip install requests`
|
|
2. Ingest log entries from syslog, JSON, or plain text files.
|
|
3. For each entry, compute SHA-256 hash of: previous_hash + timestamp + log_content.
|
|
4. Store the chain as a JSON ledger with entry index, timestamp, content hash, previous hash, and chain hash.
|
|
5. Verify chain integrity by recomputing all hashes and detecting breaks.
|
|
6. Optionally anchor checkpoint hashes to an external timestamping service.
|
|
|
|
```bash
|
|
python scripts/agent.py --log-file /var/log/syslog --chain-file log_chain.json --verify --output integrity_report.json
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Chain Entry Structure
|
|
```json
|
|
{"index": 42, "timestamp": "2024-01-15T10:30:00Z", "content_hash": "a1b2c3...",
|
|
"prev_hash": "d4e5f6...", "chain_hash": "SHA256(prev_hash + timestamp + content_hash)"}
|
|
```
|
|
|
|
### Tamper Detection
|
|
If entry 42 is modified, chain_hash[42] will not match SHA256(chain_hash[41] + ...), and all entries from 42 onward will be flagged as invalid.
