Google vulnerability scanners are best known for finding vulnerabilities in your App Engine, Google Kubernetes Engine (GKE), and Compute Engine web apps.
Sophisticated threats aimed at your Google Cloud resources can be detected and patched in real-time with the help of GCP vulnerability scanning tools.
With its many distinct technologies and locations, the cloud environment mandates a different security method than a traditional on-premise data center.
To detect and mitigate threats targeting your Google Cloud resources, we walk you through this in-depth guide to provide deep insights about the feature and best practices.
What is the GCP vulnerability scanning tool?
The tool that automatically scans and detects exploitable vulnerabilities in the GCP infrastructure and application resources on the Google Cloud Platform is called the GCP vulnerability scanning tool. GCP scans different GCP resources like Compute Engine instances, App Engine apps, Kubernetes clusters, databases, and websites.
GCP assigns severity scores and provides remediation guidance to help organizations fix issues and strengthen the security of their GCP environments.

GCP vulnerability scanning tools should scan for vulnerabilities across all primary GCP services like Compute Engine, Kubernetes Engine, App Engine, Cloud Storage, SQL, and openness at the OS, network, and app levels, such as SQL injection, cross-site scripting (XSS), and remote code execution (RCE).
2. Continuous Scanning
Vulnerabilities can emerge anytime, so continuous scanning is essential for resources and workloads. It detects new vulnerabilities as they arise and provides real-time alerts. GCP vulnerability scanning tools comprehensively scan all assets in a user’s cloud infrastructure, including virtual machines, containers, and applications.
3. Integration with GCP
Google Security Scanner should integrate well with various GCP services like SIEMs, ticketing systems, and other DevOps tools. It allows for easy monitoring, alerting, and workflow automation and enables the device to provide better visibility into your security posture.
4. Vendor Reputation and Support
Having multiple support options like phone, email, documentation, and onboarding support helps the onboarding process and addresses issues during usage. The vendor providing the tool must have a proven track record of delivering reliable and effective vulnerability scanning tools.
5. Compliance checks
All Google cloud scanners should detect violations and scan for compliance with standards like PCI DSS, HIPAA, GDPR, etc.
6. Remediation recommendations
In addition to identifying flaws, it should make recommendations for addressing them. The recommendations should be prioritized based on the severity of the vulnerability and the potential impact on your GCP environment.
Importance of GCP vulnerability scanning software
- Identify Weaknesses: GCP vulnerability scanning tools help identify vulnerabilities, misconfigurations, and potential security weaknesses in cloud environments.
- Risk Mitigation: Risk mitigation involves applying security patches, updating software, changing configuration settings, or implementing additional security controls.
- Proactive Security Posture: GCP vulnerability scanning tools help maintain an aggressive security posture by identifying vulnerabilities before attackers can exploit them.
- Patch Management: Google cloud scanners can help manage security patches and updates across the cloud environment. The scanners identify which patches must be applied, schedule patching activities, and monitor patch compliance.
- Integration with DevOps: GCP vulnerability scanning tools can be integrated with DevOps processes to ensure security is built into the cloud infrastructure. Vulnerability scanning is part of the continuous integration and deployment (CI/CD) pipeline. Google Cloud security scanners can be integrated with SIEM systems, incident response tools, and other security services.
- Dynamic environments: GCP environments can change frequently with updates, new resources, etc. GCP vulnerability scanning tools are designed to work in dynamic cloud environments where resources are constantly being created, moved, and deleted.
What are the features of GCP vulnerability scanning tools?
1. Asset Discovery
The GCP scanning tools include asset discovery capabilities, which help users identify all the assets in their cloud infrastructure, including those that may have been forgotten or overlooked.
Asset discovery helps ensure that all potential security risks are identified and addressed. GCP tools use cloud metadata to discover assets and can be configured to find help in specific regions or projects.
2. Severity Assessment
Once vulnerabilities are identified, the scanning tools assess each exposure’s severity. GCP vulnerability scanning tools assess the severity of vulnerabilities based on industry-standard scoring systems such as the Common Vulnerability Scoring System (CVSS).
Severity assessment enables users to prioritize which vulnerabilities to address first based on their potential impact on the security of their cloud infrastructure.
3. Reporting and dashboards
The reports and dashboards include information on the number and severity of vulnerabilities discovered, the status of remediation efforts, and compliance status.
The new reporting and dashboard feature helps users stay informed about the security of their cloud infrastructure and make data-driven decisions about how to prioritize remediation efforts.
The Best practices for Google security scanners
Google Cloud security scanners are built on one of the most secure data infrastructures in the world. But it’s your responsibility to ensure your Google Apps security settings are set up correctly by following some of the best practices.
- Use Google’s Site Isolation feature to isolate each site in a separate sandbox or process. This contains vulnerabilities and prevents them from spreading.
- Integrate Cloud Malware Threat Protection to avoid data loss and severe threats to your organization’s customers, employees, trade secrets, and more.
- Require two-factor authentication for all Google accounts to add an extra layer of security beyond passwords.
- Enable automatic updates for all Google apps and plugins. Updates contain the latest security fixes for known vulnerabilities.
- Run regular security scans with Google’s Chrome Security Scanner and Android Device Manager to detect threats, malware, and vulnerabilities. Scan at least monthly.
- Limit employee access on a need-to-know basis. Only grant the minimum required access and promptly revoke access when no longer needed.
- Enable login notifications and activity auditing to monitor for suspicious activity. Investigate any abnormal login attempts or behavior.
- Provide ongoing security awareness training for employees on secure password practices, identifying phishing attempts, and other best security behaviors.
- Monitor the system and audit the Google Cloud security settings of the Google Cloud security scanner.
GCP vulnerability scanning identifies security weaknesses within Google Cloud Platform environments and infrastructures. GCP scans detect configuration issues, missing patches, and vulnerable software. Many vulnerability scanning tools exist for GCP.
Best practices include implementing multi-factor authentication, reviewing and prioritizing vulnerabilities, and rapidly remediating high-severity issues. When choosing a tool, consider the cost, compliance checks, compatibility with GCP, integration with DevOps tools, number of vulnerabilities detected, and false favorable rates to find a suitable option. Regular scanning with the right tool can significantly improve the security and resilience of your GCP infrastructure.
