🏦 SIDBI PII Encryption Review

Observation-Based Security Assessment
Skillmine Technology Consulting Pvt. Ltd.
📅 November 28, 2025 - Kickoff Meeting
⏰ Duration: 10 Working Days | End: December 12, 2025

📋 Today's Agenda

🎯 Engagement Overview

Objective

Assess whether PII data is stored, transmitted, or logged in unencrypted/clear-text format across SIDBI's infrastructure.

Scope

  • Oracle 19c (On-premise)
  • AWS S3 Buckets (5-6)
  • SQL Server (Cyfuture + ESDS x4)
  • Security Tools (SIEM, DAM, EDR, AV)
Final Deliverables: Assessment Report + CERT-In Certification

📋 Detailed Scope of Work

Objective: To assess whether PII data is stored, transmitted, or logged in an unencrypted or clear-text format across on-premises, cloud, and co-location environments. CERT-In certification will be provided upon completion.

💾 Data at Rest

Oracle 19c (On-premise): Verify TDE encryption status for PII data
AWS S3 Buckets (5-6): Validate SSE/KMS encryption configuration
SQL Server (Cyfuture + ESDS x4): Review TDE implementation and key management

🌐 Data in Transit

Traffic Sampling: Review exit points/perimeter devices (minimum 10 samples)
TLS Configuration: Evaluate Oracle, AWS, and SQL Server data transfers for encryption
Protocol Verification: Inspect perimeter devices for secure communication protocols

📋 Logs Review

SIEM, DAM, EDR/XDR, Antivirus: Confirm PII is not forwarded in clear text
Log Transfer Security: Assess whether logs are transmitted with encryption enabled
Pattern Detection: Search for PII exposure in security monitoring platforms

🔄 Our Assessment Process - 4 Steps

Step 1: Understand the System As-Is

📊 Initial discovery to understand your infrastructure, architecture, and current security controls

Step 2: Interview & Evidence Collection

📝 Structured questionnaire with stakeholders + Observation sessions where SIDBI team demonstrates systems and provides proof/evidence

Step 3: Analysis & Report Preparation

📑 Analyze PII encryption findings (Data at Rest, In Transit, Logs), perform gap analysis against best practices, and prepare comprehensive report on PII protection posture

Step 4: Daily Status Updates

📧 Daily progress reports to stakeholders ensuring transparency and alignment

👀 Observation-Based Audit Model

Key Principle: Skillmine has NO direct access to any systems. SIDBI team performs all actions while Skillmine observes and documents.

🏢 Onsite Mode

  • SIDBI staff uses their own laptop
  • Logs into systems
  • Navigates screens as requested
  • Skillmine observes and takes notes

🌐 Remote Mode

  • SIDBI shares screen via Teams/Zoom
  • Logs into systems
  • Navigates as requested
  • Skillmine observes remotely
