What are Cloud Native Applications?

A software program specially created and developed to utilize the architecture and concepts of cloud computing fully is known as a cloud-native application. Cloud-native apps are explicitly designed to take advantage of cloud settings’ scalability, flexibility, and resilience, unlike traditional apps, which might have started as on-premises servers and moved to the cloud.

Cloud-native applications also use orchestration and containerization technologies like Docker and Kubernetes. Applications may run consistently in various cloud providers and on-premises infrastructure environments thanks to containers, and orchestration solutions handle these containers’ deployment, scaling, and management.

Features:

  • Microservices Architecture:

Microservices design, which divides an application into tiny, loosely linked services that can be developed, deployed, and scaled separately, is frequently used to build cloud-native apps. Rapid development and adaptability are encouraged by this architecture.

  • Containerization:

Individual microservices are frequently packaged and deployed using containers such as Docker containers. A lightweight and uniform environment that can be used anywhere, from development to production, is provided by containers.

  • Orchestration:

Containers’ deployment, scaling, and operation are managed and automated by container orchestration platforms such as Kubernetes. Microservice load balancing and high availability are guaranteed by orchestration.

  • Continuous Integration and Continuous Deployment (CI/CD):

CI/CD pipelines are frequently used by cloud-native applications to automate code change deployment and testing. Faster development cycles and the capacity to react swiftly to client needs are the results.

  • Elastic Scalability:

Cloud-native apps can adjust their scaling dynamically to accommodate variations in workload. Their adaptability enables them to manage surges in traffic and reduce the wastage of resources during times of reduced demand.

  • Resilience:

Cloud-native applications are built to be resilient and fault-tolerant. They may gracefully tolerate failures by automatically recovering or rerouting traffic to healthy instances.

  • Decentralized Data Management:

Cloud-native apps frequently use decentralized databases and data stores, such as NoSQL databases and object storage, to accommodate the distributed nature of microservices.

  • API-Driven:

Cloud-native applications depend heavily on APIs. They facilitate communication between several microservices and integration with external systems and other services.

Security Tips For Cloud Native Applications

1. Implement Zero Trust Security:

A “Zero Trust Security” concept assumes that nobody can be relied upon by default, neither inside nor outside the company. Strict identity verification and least-privilege access constraints are enforced by it. With this method, all users and devices must authenticate and verify their identity to access resources regardless of whether they are connected to the corporate network. It is essential for thwarting lateral attacker movement and insider threats.

2. Multi-Factor Authentication (MFA):

Users must present two or more forms of identity as part of the multi-factor authentication (MFA) security procedure to be allowed access to a system, network, or application. This usually entails the user having something (like a hardware token or smartphone) and knowing something (like a password). By adding a layer of security, multi-factor authentication makes it much harder for unauthorized individuals to obtain access.

3. Continuous Monitoring and Logging:

Constantly scanning and evaluating an environment for security flaws and threats is known as continuous monitoring. Comprehensive logs are generated to monitor user activities, system modifications, and possible security issues. Suspicious activity or security breaches can be quickly identified and addressed thanks to effective monitoring, which supports enterprises in keeping a solid security posture.

  • Configure thorough logging for every cloud service.
  • Make use of solutions for centralized log management and monitoring.
  • Set up alerts for abnormalities and security incidents.

4. Data Encryption:

Data encryption entails converting data into a secure format (cipher) to prevent unauthorized access. It can be used for both transit data (data sent over networks) and data at rest (data being stored). Sensitive data is vitally protected by encryption, ensuring that even if a hostile actor got access to it, they couldn’t read it without the decryption keys.

5. Secure DevOps (DevSecOps):

The pipeline for development and operations, or DevOps, is enhanced by integrating security measures. It implies that security is integrated into the software development lifecycle at every level, not added on as an afterthought. This approach includes automated security testing, vulnerability scanning, and code analysis to ensure security is considered from the beginning of design through the actual deployment of the system in production.

6. Incident Response Plan:

An incident response plan describes the actions to be taken during a security incident or breach. It lays up the roles, duties, lines of communication, and steps to take to lessen and recover from security events. In a security breach, a business can minimize damage, cut downtime, and recover faster with a well-defined incident response strategy.

7. Third-Party Risk Assessment:

Evaluating the security posture of outside suppliers, partners, or vendors who handle your data or have access to your systems is known as third-party risk assessment. It guarantees that these outside parties adhere to your security guidelines and don’t create weaknesses within your ecosystem. Frequent evaluations assist you in controlling and reducing any dangers.

8. Serverless Security:

Protecting applications developed with serverless computing platforms, such as AWS Lambda or Azure Functions, is the primary goal of serverless security. To keep serverless apps safe, security precautions include managing secrets, configuring the proper permissions, and watching for unusual activity.

  • For serverless functions, set up appropriate access controls.
  • Observe how functions are being executed and provide alerts for any unusual behavior.
  • Use the runtime security features.

9. Identity and Access Management (IAM):

Managing user access to resources and systems is a part of IAM. It includes rights management, role-based access control (RBAC), user provisioning, and de-provisioning. Robust Identity and Access Management (IAM) Protocols ensure that only those with permission can access specific resources and that their access is restricted to what is required to perform their jobs.

10. Employee Training:

The training of employees is an essential component of cybersecurity. It includes teaching staff members about security best practices, how to identify and handle security threats, and how crucial it is to safeguard confidential data. The first line of defense against social engineering attacks and other security concerns is frequently knowledgeable personnel.

Conclusion:

In 2023, cloud-native application security will be more critical than ever due to the changing threat landscape. Adopting a thorough and proactive security strategy is crucial. This includes implementing Zero Trust, compliance and governance, encryption, strong IAM, serverless security, container security, API security, and logging and monitoring. A more secure cloud-native system also benefits from continuous testing, personnel training, third-party risk management, and a thoroughly documented incident response strategy. In the current technological era, enterprises can reduce risks and safeguard their cloud-native apps by adhering to these security recommendations.
