Mitigation Strategies Analysis for apache/shardingsphere

Mitigation Strategy: Implement Robust Sharding Key Management

  • Description:
    1. Step 1: Sharding Key Design: Design sharding keys that are based on non-sequential, non-predictable attributes. Avoid using easily guessable patterns like incrementing IDs or predictable timestamps. Consider using UUIDs, hashed values, or combinations of multiple attributes within ShardingSphere configuration.
    2. Step 2: Key Generation Security: Implement secure key generation processes. If using application-generated keys, ensure the generation logic is robust and resistant to reverse engineering. If using database-generated keys, ensure database security best practices are followed and integrated with ShardingSphere's key generation if applicable.
    3. Step 3: Key Rotation (If Applicable): For sensitive data, consider implementing a key rotation strategy for sharding keys over time to further reduce predictability and potential compromise window, and ensure ShardingSphere can handle key rotation if implemented.
    4. Step 4: Documentation and Training: Document the sharding key design and generation process clearly for developers and operations teams working with ShardingSphere. Provide training on the importance of secure sharding key management within the ShardingSphere context.
    • Threats Mitigated:
      • Threat 1: Data Leakage due to predictable keys (Severity: High) - Attackers could guess or infer sharding keys and access data belonging to other users or tenants through ShardingSphere.
      • Threat 2: Targeted attacks on specific shards (Severity: Medium) - Attackers could target specific shards known to contain valuable data by manipulating or predicting sharding keys routed by ShardingSphere.
    • Impact:
      • Data Leakage: High reduction - Significantly reduces the likelihood of unauthorized data access based on key predictability within ShardingSphere managed environment.
      • Targeted attacks: Medium reduction - Makes it more difficult for attackers to specifically target shards via ShardingSphere, but doesn't eliminate all shard-targeting risks.
    • Currently Implemented: Yes, a UUID-based sharding key generation is implemented in the data ingestion service interacting with ShardingSphere.
    • Missing Implementation: Review and potential refactoring of sharding key logic for legacy data migration processes that are managed by or interact with ShardingSphere.

Mitigation Strategy: Enforce Strict Access Control Across Shards

  • Description:
    1. Step 1: Database-Level ACLs: Configure database-level Access Control Lists (ACLs) for each backend database shard managed by ShardingSphere.
    2. Step 2: Principle of Least Privilege: Grant database users and application roles only the minimum necessary privileges required to access and manipulate data within each shard accessed through ShardingSphere. Avoid using overly permissive roles like db_owner or root.
    3. Step 3: ShardingSphere User Mapping: Configure ShardingSphere's user mapping to ensure that application users are mapped to appropriate database users with restricted access on backend shards, as enforced by ShardingSphere.
    4. Step 4: Regular Access Review: Periodically review and audit database access control configurations for each shard and ShardingSphere user mappings to ensure they remain aligned with security policies within the ShardingSphere managed environment.
    • Threats Mitigated:
      • Threat 1: Unauthorized access to sensitive data in shards (Severity: High) - If access control is weak, attackers who compromise ShardingSphere or an application using it might gain access to all sharded data.
      • Threat 2: Lateral movement within the sharded environment (Severity: Medium) - Weak shard access control can facilitate lateral movement if an attacker gains initial access to one shard via ShardingSphere.
    • Impact:
      • Unauthorized access: High reduction - Significantly limits unauthorized access to data at the database level within ShardingSphere managed shards.
      • Lateral movement: Medium reduction - Makes lateral movement more difficult but doesn't completely prevent it if application-level vulnerabilities exist alongside ShardingSphere.
    • Currently Implemented: Partially implemented. Database-level ACLs are in place, but ShardingSphere user mapping needs further refinement.
    • Missing Implementation: Detailed ShardingSphere user mapping configuration and regular automated access control reviews specifically for ShardingSphere configurations.

Mitigation Strategy: Encrypt Sensitive Data at Rest and in Transit within Sharded Databases

  • Description:
    1. Step 1: Database Encryption at Rest: Enable database-level encryption features (e.g., Transparent Data Encryption - TDE) for each backend database shard managed by ShardingSphere to encrypt data at rest.
    2. Step 2: Secure Connection Configuration (TLS/SSL): Configure TLS/SSL encryption for all connections between ShardingSphere and backend databases. Ensure strong cipher suites are used and certificates are properly managed for ShardingSphere connections.
    3. Step 3: Data Masking/Tokenization (Optional): For highly sensitive data accessed through ShardingSphere, consider implementing data masking or tokenization techniques in addition to encryption to further protect data in non-production environments or for specific use cases interacting with ShardingSphere.
    4. Step 4: Key Management: Implement a secure key management system for encryption keys used for data at rest and in transit within the ShardingSphere environment. Follow key rotation and secure storage best practices relevant to ShardingSphere's data handling.
    • Threats Mitigated:
      • Threat 1: Data breach in case of physical shard compromise (Severity: High) - If a physical shard managed by ShardingSphere is stolen or compromised, encryption at rest protects data confidentiality.
      • Threat 2: Eavesdropping on network traffic between ShardingSphere and shards (Severity: Medium) - TLS/SSL encryption prevents eavesdropping and data interception during transmission between ShardingSphere and shards.
      • Threat 3: Insider threats with physical access to database servers (Severity: Medium) - Encryption at rest mitigates risks from unauthorized physical access to storage media of shards managed by ShardingSphere.
    • Impact:
      • Data breach: High reduction - Significantly reduces the impact of a physical shard compromise within ShardingSphere context by rendering data unreadable without encryption keys.
      • Eavesdropping: High reduction - Effectively prevents eavesdropping on network traffic between ShardingSphere and shards.
      • Insider threats: Medium reduction - Mitigates but doesn't eliminate insider threats, as authorized users with key access through ShardingSphere can still access data.
    • Currently Implemented: TLS/SSL is configured for ShardingSphere connections. Database encryption at rest is partially implemented on some shards but not all within the ShardingSphere setup.
    • Missing Implementation: Full database encryption at rest deployment across all shards managed by ShardingSphere and formal key management system implementation for ShardingSphere's encrypted data.

      • Undiscovered vulnerabilities: High reduction - Proactive testing significantly reduces the risk of unknown ShardingSphere vulnerabilities being exploited.
      • Misconfigurations/weaknesses: High reduction - Audits and testing help identify and remediate existing ShardingSphere security weaknesses.
    • Currently Implemented: Security audits and penetration testing are performed ad-hoc and not regularly scheduled, specifically for ShardingSphere.
    • Missing Implementation: Establishment of a regular schedule for security audits and penetration testing specifically targeting the ShardingSphere implementation. Formalized process for ShardingSphere vulnerability remediation and follow-up testing.
