Monitoring

The monitoring system is an essential element of our log security architecture. It allows real-time surveillance of log file integrity, detection of any unauthorized modifications, and alerts administrators in case of an incident.

Surveillance Dashboard​

Our platform features a secure dashboard with individual authentication. Each user has their own credentials to access monitoring information.

Statistics and Performance​

The dashboard provides detailed statistics on the overall system status, including:

  • General statistics: Number of hashes, encrypted files, and processed messages
  • System performance: CPU, memory, and disk usage
  • Service status: Real-time monitoring of critical components (SFTP, Blockchain, Server)
  • Hedera TopicID: Tracking of blockchain topic ID.0.XXXXXX where hashes are published

Alert History​

The monitoring system maintains a complete history of raised alerts:

Alert Details​

For each alert, the system preserves detailed information enabling forensic analysis:

  • Name of the concerned log file
  • Date and time of detection
  • Status: restored (in case of an integrity test) / unrestored
  • Original hash
  • New hash / deleted hash
  • Email sent to administrator: yes / no
  • IP address of the server concerned by the alert

Blockchain Verification via Hashscan.io​

Our system publishes all hashes on the Hedera blockchain to guarantee their immutability. These entries can be independently verified via the Hashscan.io blockchain explorer using the TopicID.

This public verifiability confirms that the hashes have not been altered in our own storage system with MongoDB and offers an additional layer of security and transparency.

Email Alert System​

In case of anomaly detection (file modification or deletion), the system automatically sends an alert email to administrators.
