Cloud Native Security: What Does It Really Mean?

As enterprises move more of their workloads to the cloud, they must also adapt their security strategies to account for this shift. But what does “cloud-native security” really mean?

In this article, we explore the concept of cloud-native security and discuss its key features. We also offer some tips on how enterprises can make the transition to a cloud-native security approach.

What Is Cloud Native?

In recent years, the term “cloud native” has become increasingly popular in the tech industry. While the term is often used to describe applications or architectures that are designed to run in a cloud environment, there is no clear consensus on what “cloud native” actually means.

For some, cloud-native simply refers to any application that runs in the cloud. Others believe that cloud-native applications must be designed specifically for a cloud environment and take advantage of cloud-specific features such as scalability and elasticity. Still, others believe that cloud-native applications should be built from the ground up using a microservices architecture.

The term “cloud native” was coined by Adrian Cockcroft, an engineering director at Netflix. In a 2014 blog post, Cockcroft described how Netflix adopted a microservices architecture and migrated its applications to run in the cloud as part of its “Nuclear Option” initiative. In a 2015 interview with InfoWorld, Cockcroft described cloud-native applications as “built from the ground up for the cloud, using microservices and an event-driven approach. They’re designed to be highly scalable and resilient.

The Principles of Cloud Native

Simply put, cloud-native is a term used to describe applications or services that are built specifically for the cloud. These applications are designed to take advantage of the cloud’s unique properties and capabilities, such as scalability, flexibility, and agility.

However, cloud-native also comes with its own set of challenges, one of which is security. The security challenges of cloud-native applications are a big topic, especially considering that many of these applications are built using containers or microservices. In this post, I’ll briefly discuss some of the main concepts behind cloud-native and how they relate to security.

The Components of Cloud Native

There are four main components of cloud-native applications: containers, microservices, DevOps, and the cloud itself.

  • Containers are a way of packaging software so that it can be deployed anywhere, without any dependencies on the host system. This makes them ideal for running in the cloud, where infrastructure is often ephemeral.
  • Microservices are a type of architecture in which an application is divided into small, independent services. This makes developing and deploying new features easier and makes the application more resilient to failure.
  • DevOps is a set of practices that helps teams to deliver software quickly and reliably. DevOps is an approach that combines software development and operations. This makes it possible to quickly develop, test, and deploy new features. The cloud itself is the foundation of cloud-native applications.
  • The Cloud. Cloud-native applications can be deployed to any cloud and can take advantage of the elasticity and scalability of the cloud.

How to Secure Your Cloud Native Environment

To be genuinely cloud native, an application must take advantage of the many benefits the cloud offers, such as scalability, flexibility, and efficiency. And one of the most important aspects of any cloud-native application is security. Security is a crucial component of any application and is even more critical in the cloud.

Securing Containers:

As the world moves increasingly towards a digital landscape, container security has become a hot topic. Containers are a type of virtualization that allows for the abstraction and isolation of applications from their underlying infrastructure. This makes them appealing to developers and organizations looking to increase efficiency and speed of deployment. However, containers also present new challenges in terms of security. Because they are lightweight and portable, malicious actors can more easily target containers. Organizations must be aware of the risks and take steps to secure their containerized environments. There are several key considerations for securing containers. First, it is essential to understand the host environment and how the containers interact with it. This includes understanding which network services will be exposed and ensuring that only authorized users have access. Second, proper image management is essential to maintaining security in a containerized environment. Third, organizations should use a trusted registry to prevent the introduction of malicious images. Finally, organizations must ensure that container registry can be trusted by ensuring that they are secure and have a solid reputation.

Microservices Security:

Microservices have been a popular topic in the software development world for the past few years. With the rise of containerization and orchestration, microservices have become attractive for developers looking to build scalable and resilient applications. However, microservices architectures require an entirely new approach to security. Unlike traditional monolithic applications, microservices introduce a shift from a centralized security model to a decentralized model. Microservices are typically packaged and deployed separately. As such, there is no central control point for securing them. However, microservices come with their own set of challenges, one of which is security. Because each microservice is its own self-contained unit, it is difficult to secure them all at once. This is especially true when you have hundreds or thousands of microservices.

DevOps Security:

DevOps security is a term used to describe the security aspects of the DevOps methodology. DevOps is a software development approach that emphasizes communication, collaboration, and integration between software developers and information technology (IT) professionals. DevOps security aims to provide a secure environment for application development, testing, and deployment.

DevOps security measures include code signing, access control, and auditing. Code signing is a process that ensures that only code that has been approved by a trusted authority can be executed. Access control ensures that only authorized users can access sensitive data and systems.

Auditing provides a record of all activity in the system, which can be used to identify potential security issues. DevOps security measures include code signing, access control, and auditing.

Cloud Security:

As more businesses move their data and applications to the cloud, security concerns are top of mind. But with the right security measures in place, the cloud can be a safe and secure environment for your data. When it comes to cloud security, there are three key areas to consider: data security, application security, and identity and access management.

  • Data security is all about protecting your data from unauthorized access or theft. To do this, you need to encrypt your data at rest and in transit. You also need to implement strong access control measures so that only authorized users can access your data.
  • Application security is about protecting your applications from attacks. You need to implement firewalls and intrusion detection/prevention systems to do this. You also need to keep your applications up-to-date with the latest security patches.
  • Identity and access management is about managing your users’ identities and ensuring that they have the appropriate privileges to do their jobs. You need to implement the least privilege, which means that a user should be allowed to access only the resources they need to do their jobs.

“Cloud-native security” means that security is a fundamental design consideration for cloud-based applications and services. By taking a “security first” approach, organizations can ensure that their data and resources are protected against potential threats. As the use of cloud-based services continues to grow, so too will the need for effective security measures.
