Secure Database

1. Introduction to Database Security

• Importance of Securing Databases
  • Role of databases in organizations
  • Consequences of data breaches
• Common Threats to Databases
  • External attacks (hackers, malware)
  • Insider threats
  • Physical threats
• Overview of Security Measures
  • Preventative, detective, and corrective controls

2. Authentication and Authorization

• Authentication Concepts
  • Definition and purpose
  • Methods: passwords, biometrics, multi-factor authentication
• Authorization Concepts
  • Access control principles
  • Privilege management
• Integration of Authentication and Authorization
  • Session management
  • Common database authentication protocols

3. Encryption Techniques for Databases

• Encryption Overview
  • Purpose and importance
• Symmetric Encryption
  • Algorithms (AES, DES)
  • Use cases in databases
• Asymmetric Encryption
  • Algorithms (RSA, ECC)
  • Key exchange mechanisms
• Hashing
  • Purpose and algorithms (SHA family, MD5)
  • Use in data integrity and password storage
• Key Management
  • Key generation, storage, rotation, and destruction

4. Database Access Control

• Role-Based Access Control (RBAC)
  • Role definitions and assignments
• Mandatory Access Control (MAC)
  • Security labels and classifications
• Discretionary Access Control (DAC)
  • Owner-based permissions
• Implementation Techniques
  • Granting and revoking permissions
  • Access control lists (ACLs)

5. Database Auditing and Logging

• Importance of Auditing
  • Accountability and compliance
• Types of Events to Log
  • Logins/logouts
  • Data modifications
  • Access attempts
• Monitoring Database Activity
  • Real-time vs batch monitoring
• Interpreting Audit Logs
  • Identifying suspicious activities
  • Reporting and alerting mechanisms

6. Secure Database Design Principles

• Least Privilege Principle
• Data Normalization
  • Reducing data redundancy and anomalies
• Input Validation
  • Preventing injection attacks
• Secure Coding Practices
  • Avoiding common vulnerabilities

7. Database Security Threats and Countermeasures

• Common Threats
  • SQL Injection
  • Insider threats
  • Unauthorized access
• Countermeasures
  • Input sanitization
  • Strong authentication
  • Regular patching and updates
  • Network security measures

8. Data Masking and Redaction

• Purpose and Benefits
• Data Masking Techniques
  • Static and dynamic masking
  • Tokenization
• Data Redaction
  • Methods for obscuring sensitive fields
