What is cloud-native security?

Cloud-native security has several key elements that work together to protect applications and infrastructure:

Containers and Kubernetes security. Containers package applications and their dependencies, enabling application portability and scalability. Kubernetes orchestrates these containers, managing deployment and scaling. Security for containers and Kubernetes includes image scanning, runtime monitoring, and securing control planes. Misconfigured Kubernetes clusters are a common attack vector, making configuration management critical.

API security. Microservices communicate through APIs, which must be secured to prevent unauthorized access. API security includes authentication, authorization, and rate limiting. API gateways provide centralized control and monitoring, reducing the risk of data exposure.

CNAPPs. CNAPP solutions unify multiple security capabilities, including cloud security posture management (CSPM). These unified platforms provide end-to-end visibility across the application lifecycle, enabling risk-based prioritization, consistent policy enforcement, and faster threat detection and response.

Compliance and governance. Organizations must adhere to regulatory compliance standards such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), and the Payment Card Industry Data Security Standard (PCI-DSS). Automated compliance checks and reporting help maintain alignment with standards, reducing the risk of legal penalties.

AI workloads. AI models and data pipelines introduce unique cloud security challenges. Protecting training data, preventing model tampering, and ensuring ethical AI practices are essential. Security measures must address both the confidentiality and integrity of AI systems.

Cloud data security. Data is a primary target for attackers. Encryption, masking, and access controls protect sensitive information. Database security includes monitoring for unauthorized queries and ensuring proper configuration.

Identity permissions. Excessive privileges increase the risk of compromise. Identity governance tools help enforce the principle of least privilege and monitor for anomalies. Privilege escalation attacks are common in cloud environments, making identity security a top priority.

Multicloud posture consistency. Multicloud security is a concern for organizations using multiple cloud providers, each with unique security tools and configurations. Maintaining consistent policies across environments reduces complexity and risk.

Cloud-native container security. This includes securing container registries, implementing runtime controls, and monitoring for vulnerabilities in container images.

Cloud workload protection (CWPP). CWPP solutions provide visibility and threat detection for workloads across environments, including virtual machines, containers, and serverless functions.

Another key concept to know is the “four C’s” of cloud-native security. Each “C” represents one of the layers that must be secured to ensure a defense-in-depth approach:
 

1. Code—application code and infrastructure as code (IaC), including open-source dependencies.
2. Container—container images and runtimes.
3. Cluster—orchestration platforms such as Kubernetes.
4. Cloud—underlying cloud infrastructure, such as networks, virtual machines, storage, identities, and configurations.

We’ve covered many factors to consider as you devise your organization’s strategy. Here are a few more points to keep in mind as you choose the tools you need to strengthen your cloud security posture:
 

• Implement Zero Trust alongside microsegmentation to limit lateral movement and to reduce the impact of attacks.
• Encrypt data in transit and at rest to ensure the confidentiality and integrity of sensitive information.
• Automate vulnerability scanning in CI/CD pipelines to detect issues as early as possible in the development process.
• Conduct regular compliance audits and posture assessments to reduce your risk of incurring regulatory penalties.
• Enable continuous monitoring and threat detection, paired with dynamic risk prioritization, so security teams can focus first on the attack paths most likely to lead to a breach.

If you opt to adopt a CNAPP, be sure it offers:
 

• Agentless coverage for broad visibility without performance impact.
• Attack path prioritization to focus on critical risks that could lead to costly breaches.
• Identity permission reduction to minimize exposure from excessive privileges.
• Integration with an extended detection and response (XDR) solution for unified threat detection.
• Lifecycle-based remediation for faster resolution of vulnerabilities.
