Our findings that the top ten Docker images contain over 8,000 paths to vulnerabilities, coupled with the observation that for almost every dependency present in these images a vulnerabilities was added, make a strong case for using minimal base images.
- SQL Server Runs on Windows, Linux and Docker Containers
- Graph Database Capabilities
- Python Support
- Resumable Online Index Rebuild
- New CLR Security Model
- Identity Cache
- Adaptive Query Processing
- Scaling Out Integration Services
