We need to develop a secure proxy for Redis that acts as an intermediary between clients and the Redis server. This proxy will introduce additional security features, such as access control, encryption, command filtering, and rate limiting, making Redis safer to use in production environments. The goal is to provide a transparent layer that enforces security policies without requiring significant changes to existing Redis clients or infrastructure.
Develop a proxy that sits between Redis clients and the Redis server, handling all communication.
Implement access control mechanisms to restrict which clients can connect and which commands they can execute.
Introduce encryption for data in transit to prevent eavesdropping and tampering.
Filter and log commands to prevent potentially dangerous operations
Implement rate limiting to protect against abuse and denial-of-service (DoS) attacks.
Provide detailed logging and monitoring of all interactions with Redis through the proxy.
Ensure compatibility with existing Redis clients and commands.
Proxy Design and Architecture:
Design the architecture of the proxy, focusing on modularity and security.
Define the communication flow between clients, the proxy, and the Redis server.
Outline the security features to be implemented, including access control, encryption, command filtering, and rate limiting.
Access Control Implementation:
Implement a basic access control list (ACL) to restrict which clients can connect to the Redis server through the proxy.
Allow configuration of ACLs based on client IP, user authentication, and command whitelisting/blacklisting.
Provide a mechanism for administrators to easily update and manage ACLs.
Encryption for Data in Transit:
Implement TLS
Command Filtering and Logging:
Implement command filtering to block potentially dangerous commands like FLUSHALL, and CONFIG SET.
Allow administrators to configure which commands are allowed, blocked, or require additional logging.
Log all filtered commands and provide detailed logs for audit purposes, including the client IP, timestamp, and command executed.
Rate Limiting and Abuse Prevention:
Implement rate limiting to control the number of requests a client can make within a specified time frame.
Allow configuration of rate limits on a per-client or per-command basis.
Implement penalties for clients that exceed rate limits, such as temporary blocking or delayed responses.
Documentation
Deployment and Monitoring:
Implement monitoring and alerting for the proxy, integrating with tools like Prometheus and Grafana.
