10 GCP Security Best Practices for Busy DevOps

Google Cloud Platform (GCP) has one major standout feature: It harnesses the power of the Google ecosystem. This prowess makes GCP an attractive platform for DevOps teams seeking agility and scalability.

GCP currently has 10% of the cloud infrastructure services market. In an industry worth almost $80 billion, that means an enormous amount of users and organizations whose assets must be kept under lock and key. Developers favor GCP for the BigQuery database, which handles scale and complexity with ease. GCP’s other attractive features include its focus on data analytics and machine learning and its reputation for innovation in cutting-edge technologies like Kubernetes and serverless computing.

But in the fast-paced world of DevOps, GCP security can sometimes take a back seat. Thankfully, it doesn’t have to be a complex roadblock, as these ten best practices show.

What is GCP security?

Google Cloud Platform (GCP) is a suite of cloud computing services offered by Google, providing a robust infrastructure for building, deploying, and managing applications and services. GCP security refers to the measures and practices implemented to protect your cloud resources, data, and applications from unauthorized access, data breaches, and other security threats.

Security is a shared responsibility between the cloud provider and the customer in the cloud. As the provider, Google is responsible for securing the underlying cloud infrastructure, while customers are responsible for securing their data, applications, and resources running on GCP. This approach is known as the shared responsibility model.

GCP offers various security tools and services, such as Identity and Access Management(IAM), Cloud Armor, and Security Command Center, to help customers meet their security obligations.

Understanding the GCP Architecture

Google Cloud offers extensive services to keep up with businesses’ cloud migration demands, including:

Compute Engine: Customizable virtual machines hosted in Google’s data centers, offering a wide range of options for CPU, memory, and storage to meet your specific needs.

Cloud Storage: A highly durable and available object storage service, ideal for storing and retrieving unstructured data like images, videos, and backups.

BigQuery: A fully managed, petabyte-scale data warehouse that leverages Google’s processing power to deliver lightning-fast query responses.

5 GCP Security Challenges

While GCP offers robust security features, maintaining a strong security posture in a fast-paced DevOps environment presents several challenges. Here are five key hurdles to consider:

1. Misconfigured Identity and Access Management (IAM)

GCP’s IAM system offers granular control over resource access, but this complexity can lead to misconfigurations and excessive permissions if not managed carefully. To mitigate unauthorized access, ensuring the principle of least privilege and regularly auditing IAM roles and policies is crucial.

2. Lack of Visibility into Resources

GCP offers a wide array of services, and keeping track of all deployed resources can be difficult. Without a comprehensive inventory, it’s easy to miss shadow IT – unauthorized resources provisioned outside established processes. Limited visibility also hinders effective security monitoring and incident response, as you can’t protect what you don’t see.

3. Overly Permissive Firewalls

Firewalls are essential for controlling network traffic, but overly permissive rules can expose resources to unauthorized access. DevOps teams might be tempted to create broad firewall rules to expedite development, but this can leave resources vulnerable to attacks that exploit these open pathways.

4. Unpatched Systems

Security vulnerabilities are a constant threat, and patching systems is crucial for maintaining a secure environment. However, patching can often fall behind schedule in a fast-paced DevOps environment. Unpatched systems become easy targets for attackers who exploit known vulnerabilities.

5. Threat Modeling Gaps

Effective security requires a proactive approach, including threat modeling to identify potential attack vectors and vulnerabilities. However, many organizations struggle to keep up with the evolving threat landscape, especially in the dynamic cloud environment, leading to potential blindspots in their security posture.

10 GCP Security Best Practices for Busy DevOps Teams

By implementing these ten best practices, busy DevOps teams can significantly improve your security posture without sacrificing development speed.

1. Prioritize Security Awareness and Training

Remember, the weakest link in security is often human error. Regular security awareness training equips your team with the knowledge to identify and avoid security risks. Training should cover topics like social engineering tactics, password hygiene, and best practices for handling sensitive data.

2. Enforce Least Privilege with IAM

The principle of least privilege dictates that users should only have the minimum permissions necessary to perform their jobs. Implement IAM roles with granular permissions and avoid assigning overly broad roles. Leverage tools like Control Plane’s fine-grained access controls to enable the principle of least privilege across clouds without the hassle of IAM credentials.

3. Automate Security with Infrastructure as Code (IaC)

IaC tools like Terraform and Cloud Deployment Manager allow you to define your infrastructure configuration as code. This approach of using DevOps automation tools ensures consistent and repeatable deployments, minimizing the risk of human error that can introduce security vulnerabilities. Integrate security checks into your IaC pipelines to identify and prevent insecure configurations automatically.

4. Embrace Data Security

Data is a crown jewel, and its security is paramount. Always encrypt data at rest and in transit. GCP services like Cloud Storage and Cloud BigQuery offer built-in encryption options, making it easy to safeguard sensitive data. Additionally, utilize Cloud Key Management Service (KMS) for centralized key management and access control over your encryption keys. Alternatively, Control Plane includes built-in access control to remove this burden.

5. Centralized Logging and Monitoring

Maintaining visibility into your GCP environment is crucial for proactive security. For example, you can utilize the centralized, built-in logging tools in Control Plane to gain complete visibility into your application logs. With the real-time logging and flexible querying features, you can identify issues quickly with real-time log ingestion and powerful querying using LogQL. It’s easy to seamlessly collect and centralize logs from workloads running across multiple cloud providers and locations, and you can visualize and analyze log data through the built-in Grafana explorer.

For containerized workloads running on Kubernetes Engine (GKE), leverage Cloud Monitoring and the Stackdriver Kubernetes Engine Monitoring agent to gain deep insights into your cluster health and security posture. Not using GKE? Control Plane provides you with the visibility to optimize your Kubernetes clusters regardless of cloud.

6. Automate Workflows for Faster and More Secure Deployments

DevOps is all about automation, and security should be no exception. Automate security checks into your CI/CD pipelines to identify and address vulnerabilities early in development. Tools like Cloud Build and Cloud Functions can be used to automate security testing, IaC scanning, and configuration management tasks.

7. Leverage GCP Security Blueprints

GCP offers a library of pre-configured security blueprints that provide a starting point for securing your cloud environment. These blueprints address common security best practices and can be customized to meet your specific needs. Security blueprints can save you valuable time and effort when implementing security controls across your GCP resources.

8. Schedule Regular Security Audits

Security is an ongoing process, not a one-time fix. Schedule regular security audits to identify potential weaknesses in your GCP environment. Your security team can perform these audits internally or outsourced to a qualified external security vendor. Regular audits help ensure your security posture remains strong as your cloud environment evolves.

9. Foster a Culture of Security

Security is everyone’s responsibility, hence why your people are often called the ‘human firewall’. Promote a security culture within your DevOps team by encouraging open communication and collaboration on security matters. Recognize and reward team members who identify and report security vulnerabilities. By fostering a culture of security, you can create a more secure and resilient cloud environment.

10. Implement Continuous Threat Detection and Response (CTDR)

Don’t wait for a security breach to happen before taking action. Implement a continuous threat detection and response strategy that continuously monitors your GCP environment for suspicious activity. Cloud Security Command Center (SCC) provides threat detection capabilities and integrates with security tools like Chronicle to help you investigate and respond to security incidents more effectively.
