Top Cloud-Native Security Practices Every Organization Should Follow

Although cloud-native environments drive modern innovation and enable scalability, they also introduce new vulnerabilities that traditional perimeter-based security models cannot address. According to Orca Security’s 2025 State of Cloud Security Report, 95% of organizations have at least one cloud asset that enables lateral movement, making it easier for cybercriminals to navigate cloud environments undetected. Cloud-native security addresses this risk by protecting distributed workloads, applications and infrastructure across the entire cloud lifecycle. Some of the top cloud-native security practices organizations should follow include adopting a zero-trust security model and enforcing strong access management policies to ensure consistent and scalable cloud operations.

Continue reading to learn the top seven practices every organization should follow to improve its cloud-native security strategy.

1. Adopt a zero-trust security model

A zero-trust security model is crucial for securing cloud-native environments, where dynamic workloads and remote access are common. Traditional perimeter-based security models implicitly trust traffic within a network, but a zero-trust security model operates under the assumption that no user, identity or system should be automatically trusted — even if it’s already within the environment. In a cloud-native architecture, where resources are typically distributed across multiple cloud providers, enforcing zero-trust security requires continuous authentication and authorization for users, systems and services. Two examples of how zero-trust security is implemented in modern cloud environments include:

• Service-to-service authentication: Cloud applications must authenticate each other before communicating, similar to how users must log in to access a specific system. Service-to-service authentication enforces zero-trust security by ensuring no service is implicitly trusted, using certificates and tokens to authenticate each request.
• Network segmentation: Instead of exposing networks to broad access, zero-trust security models segment networks into smaller, more closely monitored zones. Cloud-native platforms support network segmentation through zero-trust security policies that restrict access based on defined rules, ensuring services can communicate only when strictly necessary and authorized.

2. Enforce strong Identity and Access Management (IAM)

Identity and Access Management (IAM) is a key part of cloud-native security, ensuring that only the right identities have access to appropriate resources with least-privilege access. In dynamic cloud environments, where infrastructure scales quickly, identity-first security helps organizations prevent unauthorized access. Over-permissioned identities, hardcoded secrets and improperly managed credentials are common attack vectors cybercriminals use to inflict harm, especially in CI/CD pipelines. IAM best practices include:

• Role-Based Access Control (RBAC): Assigns permissions based on a user’s job.
• Just-in-Time (JIT) access: Eliminates standing access by granting time-bound, purpose-specific privileges.
• Credential and secrets management: Securely stores and rotates service account credentials, API tokens and other secrets.

Many organizations use Keeper^® to enforce these practices across cloud-native infrastructure and Kubernetes environments with secure password, secrets and privileged access management.

3. Secure containers and Kubernetes

Modern applications are often delivered using containers and Kubernetes, making them valuable targets for cybercriminals due to their broad access to sensitive data. Misconfigured containers or exposed Kubernetes dashboards can lead to significant data breaches. To reduce these risks, organizations should scan container images before deployment to identify security vulnerabilities and potential malware. They should also protect workloads at runtime with behavioral anomaly monitoring and real-time threat detection. In addition, it’s important to enforce Kubernetes security policies like network segmentation and RBAC to reduce the risk of unauthorized access. Full visibility across clusters and namespaces helps organizations detect misconfigurations and monitor activity in real time across cloud environments.

4. Shift security left in CI/CD pipelines

“Shift-left” security means integrating security at the beginning of the software development lifecycle rather than waiting until after deployment. In cloud-native environments, a shift-left security approach is crucial for catching misconfigurations and vulnerabilities before they reach production. Organizations should embed shift-left security into code repositories, build pipelines and Infrastructure as Code (IaC) by using automated scanning and policy-as-code to secure configurations. By integrating security into earlier phases of developer workflows, organizations can improve delivery while maintaining consistent policy enforcement across every stage of the CI/CD pipeline.

5. Implement continuous monitoring and runtime protection

Static security controls cannot keep up with the speed and scalability required in modern cloud-native environments. In these environments, infrastructure changes frequently, and new code is continuously deployed. To stay ahead, organizations need full visibility and control over cloud-native security to help prevent advanced cyber threats and respond to incidents quickly. Effectively implementing cloud security best practices requires continuously monitoring workloads across clusters, detecting suspicious activity like privilege escalation and responding to runtime security incidents as they occur. With proper automation and alert prioritization, security teams can dedicate more time to responding to high-level threats and enhance their organization’s security posture in distributed cloud-native environments.

6. Protect APIs and microservices

While APIs and microservices are foundational in cloud-native environments, they also expand the attack surface by exposing many interconnected entry points that cybercriminals can exploit to access critical systems. To prevent unauthorized access, organizations should secure APIs with strong authentication and authorization, use API gateways to enforce policies and encrypt service-to-service communication to protect data at all times. Securing every API interaction and enforcing least-privilege access across microservices enables organizations to enhance their cloud security and align with zero-trust security principles.

7. Automate compliance and policy enforcement

Due to the fast-paced nature of cloud-native environments, manual compliance checks are no longer sufficient. Continuously monitoring for compliance in modern cloud environments requires automated controls to ensure security policies are consistently applied across infrastructure and pipelines. Organizations should enforce security and compliance rules using policy-as-code, automated encryption and network segmentation, along with ongoing monitoring to detect misconfigurations and compliance violations in real time. Automating compliance reduces manual effort, improves audit readiness and ensures that regulatory standards are upheld.

Common mistakes in cloud-native security practices

Even organizations with ample resources can make mistakes when enforcing cloud-native security in modern environments. Here are some of the most common cloud-native security mistakes organizations make and the consequences of those mistakes:
