Tamper Protection¶
Nyroxis includes strong tamper-protection mechanisms designed to ensure that no attacker can delete, modify, forge, or reorder logs without detection. These protections operate fully offline and are enforced inside the local database and event pipeline.
1. Hash-Chained Event Blocks¶
Each event is stored as: - Encrypted payload - Integrity hash of the block content - Sequential index - Hash of the previous block
This structure forms a hash chain.
Tampering becomes visible if: - A block is removed — next block's previous-hash will not match - A block is modified — block hash will not match - A block is injected — sequence numbers and chain hashes will fail - The sequence is reordered — index inconsistency is detected
Any mismatch breaks the chain and triggers an immediate alert.
2. Integrity Verification at Read Time¶
Every time the AI/ML engine or Dashboard reads data: - Hash is recalculated for each block - Sequence number is checked - Previous-hash match is validated
If anything has been altered, the system: - Rejects the tampered data - Flags a tamper event - Stores a security alert in the local database
All checks are local and offline.
3. Protected Write Path¶
Nyroxis Agent writes logs using: - Atomic write operations - Controlled file handles - Verified write sequences - Encrypted buffers
This prevents: - Partial writes that corrupt the chain - Injection of unverified data - Race condition corruption
4. Anti-Deletion Protection¶
If an attacker deletes event blocks: - The next block's previous-hash will not match the deleted block's hash - Nyroxis detects the gap in the chain - A tamper-deletion alert is generated and stored locally
Nothing can be removed silently.
5. Anti-Modification Protection¶
If an attacker modifies: - Timestamp - Event metadata - Event content - Block ordering
Nyroxis detects it through: - Hash mismatch on the modified block - Index inconsistency - Chain breakage
Modification is impossible without detection.
6. Anti-Injection Protection¶
If someone tries to insert fake log entries: - Sequence numbers fail validation - Hash chain validation fails - Integrity check fails
Nyroxis rejects the entire affected data slice and warns the user.
7. Platform Service Protection¶
Nyroxis System Guardian monitors Nyroxis Agent and Intelligence every 3 seconds.
If either service is stopped — by crash, system event, or deliberate interference: - Guardian detects it immediately - The shutdown attempt is logged as a security event - Corrective action is taken
The monitoring platform itself cannot be silently disabled.
Summary¶
Nyroxis tamper protection ensures: - Logs cannot be deleted without detection - Logs cannot be modified without detection - Logs cannot be injected without detection - Logs cannot be reordered without detection - The platform cannot be silently disabled
All protections operate locally, offline, and without cloud assistance — providing forensic-grade evidence integrity at all times.
