- Use
.env
files for local development (already in .gitignore) - Regularly rotate database passwords
- Monitor database access logs
-
Network Security:
- Restrict database network access to necessary hosts only
- Use firewall rules to limit database port access
- Consider using connection pooling and rate limiting
-
MCP Server Security:
