Data Tampering

The unauthorized modification of data to manipulate or compromise its integrity.

Understanding Data Tampering


Data tampering can occur at different levels:

  1. Database-Level Tampering – Altering records in SQL or NoSQL databases to commit fraud.

  2. Network-Level Tampering – Modifying data packets in transit using Man-in-the-Middle (MITM) attacks.

  3. Application-Level Tampering – Exploiting software vulnerabilities to change stored values, transactions, or logs.

Key Features of Data Tampering


  • Difficult to Detect – Attackers often cover their tracks by modifying logs or timestamps.

  • Targets High-Value Information – Financial transactions, medical records, government data.

Can Lead to Regulatory Non-Compliance – Violations of GDPR, HIPAA, PCI-DSS result in hefty penalties.

Best Practices for Preventing Data Tampering


  • Use Cryptographic Hashing (e.g., SHA-256, SHA-3) – Ensures data integrity verification.

  • Implement Write-Once-Read-Many (WORM) Storage – Prevents modifications to critical logs and records.

  • Enable Digital Signatures & Blockchain Technology – Creates immutable records resistant to tampering.

  • Regular Data Integrity Audits – Automates checks for unauthorized changes.
