To enable developer teams to deploy new applications without the extensive overhead of network and security reviews, it’s recommended to mandate the use of infrastructure as code (IaC) and enforce policies through static analysis in CI/CD pipelines. This approach ensures that security and compliance policies are checked automatically during the development process.

Step-by-Step:

Adopt IaC: Use tools like Terraform or Google Cloud Deployment Manager to manage infrastructure as code.

CI/CD Pipeline Integration: Integrate static analysis tools such as TFLint or Checkov in the CI/CD pipeline to enforce security policies.

Policy Definition: Define security policies and best practices that need to be adhered to in the code.

Automated Checks: Configure automated checks in the CI/CD pipeline to review code against these policies before deployment.

Monitor and Audit: Continuously monitor and audit deployed applications to ensure ongoing compliance.

To enhance the security of your machine learning (ML) model supply chain within a serverless architecture, it's crucial to implement measures that protect both the development and deployment pipelines.​

Option A: While limiting external dependencies and rotating encryption keys are good security practices, they do not directly address the risks associated with the ML model supply chain.​

Option B: Implementing container image vulnerability scanning during development and pre-deployment helps identify and mitigate known vulnerabilities in your container images. Enforcing Binary Authorization ensures that only trusted and verified images are deployed in your environment. This combination directly strengthens the security of the ML model supply chain by validating the integrity of container images before deployment.​

Option C: Sanitizing training data and applying role-based access controls are important security practices but do not specifically safeguard the deployment pipeline against compromised container images.​

Option D: While strict firewall rules and intrusion detection systems enhance network security, they do not specifically address vulnerabilities within the container images or the deployment process.​

Therefore, Option B is the most effective approach, as it directly addresses the security of the development and deployment pipeline by ensuring that only vetted and secure container images are used in your environment.​

Cloud Bigtable is a fully managed NoSQL database service designed to handle large analytical and operational workloads. One of its key features is the ability to replicate data across multiple geographic locations automatically, ensuring high availability and resilience. Here’s a detailed explanation:

Replication: Cloud Bigtable supports multi-cluster routing and replication across different geographic regions. This means that data can be replicated across multiple zones within a region or even across regions, providing geo-redundancy.

Automatic Handling: Once configured, Bigtable automatically manages replication without requiring manual intervention. This is in line with the company's policy for long-term data storage that necessitates automatic replication over at least two geographic places.

Use Case Suitability: Bigtable is ideal for applications that require low-latency access to large amounts of data, which makes it suitable for various use cases including analytical applications, IoT, and financial data processing.

Configuration: Setting up replication involves creating instances in multiple zones and configuring them to replicate data. Google Cloud’s management interface and APIs make this straightforward to configure and monitor.

With Google Cloud Directory Sync (GCDS), you can synchronize the data in your Google Account with your Microsoft Active Directory or LDAP server. GCDS doesn't migrate any content (such as email messages, calendar events, or files) to your Google Account. You use GCDS to synchronize your Google users, groups, and shared contacts to match the information in your LDAP server.
