The applications that are based on a new type of infrastructures like containers and serverless platforms refer to the Cloud Native and such types of platforms are being used by many organizations across the world. You can’t deny the fact that cloud-native applications are delivering amazing benefits but they are also raising challenges.
If we talk about cloud-native applications then they have a large number of moving parts. These types of applications include short-lived infrastructure elements that keep moving by the minute and this becomes one of the reasons that affect the security of a cloud-native application.
So, if you are also looking to find new strategies or tactics that can help you to strengthen the security of cloud-native applications then you are on the right page. In this article, we will help you to strengthen the security of the cloud-native application. So, with no further delay, let’s move forward to discuss more.
What Is Cloud Native?
An approach to develop or design, build, and run the application by approaching the techniques like continuous integration, container engines, and orchestrators is known as cloud-native. Nowadays the cloud is not limited to the only public cloud. It also can be a multi-cloud architecture including one or more than one cloud provider. To manage clouds in the containers the dynamic orchestration involves using tools such as Kubernetes. If you are not sure about containers then you can with serverless functions as it is being used as the substitute of containers. You can see it as another common variety of cloud-native computing.
Types of Cloud-Native Security Challenges
The cloud-native applications create major challenges that we have mentioned below. You need to understand the key challenges with the cloud-native application as it may help you to implement the new security measures to the cloud-native application.
Various Native Security Challenges
DevOps and other infrastructure originations provide microservices that help you run the cloud-native application. Virtual machines were used to run multiple processes or software functionalities earlier. But that was past nowadays. Each process, or capability is used to pack as a serverless function.
Different Architecture Patterns
The wide range of public and private clouds, cloud services, and application architectures are enclosed within the cloud-native systems. The vulnerabilities and security requirements are different for each architectural pattern. You need to find ways to secure each diverse architecture.
Environments in Flux
You should consider the fact that public and private cloud environments are constantly varying. You may need to update the microservices application on a daily basis because of rapid software release cycles. The approach should be to secure these deployments.
Tips to Secure Cloud-Native Applications
There can be various ways to strengthen the security of cloud-native applications. But we have mentioned the 6 most effective ways that will help you to secure cloud-native applications.
- Try to shift security left
If you are also using security tools that cannot control the speed, size, and dynamic network environment of cloud-native applications then you should leave the use of such tools. You should avoid adding serverless features as they can abstract the infrastructure. Many cybercriminals look for penetrability in containers and serverless function code. Whenever you are using a base image that has been retrieved from local storage or public domain make sure to check for security penetrability.

To avoid security issues, you need to go through the scanning process of images to ensure they do not have malware or malicious codes with them.
- Implement Perimeter Security
To provide security to the cloud-native application you need to apply perimeter security at the function and container level while developing a cloud-native application. As you know that in serverless applications the system is broken into multiple threads that creates several types of target possibilities for hackers.
To get rid of this issue you can use API and application security tools that are built for a cloud-native environment. As an option, you can implement perimeter security at the function and container level.
- Minimal Roles and Privileges
There may be various and many interactions between cloud-native resources. You can set unique permission to each container or serverless function to increase the security of cloud-native applications. Whenever you try to run an IAM on a per-function basis, you need to use those access controls to strengthen security.
- Secure Application Dependencies
Serverless functions may include packages like npm or PyPI. To provide ultimate protection to your application’s dependencies you should use automated tools that may improve application security during the development process. You can safeguard the cloud-native application from several malware attacks.
- Shared Responsibility for Security
You should make great bonding between the developers like Dev-ops and the security team. You need to understand the fact that although developers are not the experts of security, they should be educated in different security tactics and they can help you to strengthen the security of the cloud-native application.
- Use a Holistic Security Solution
The McAfee Total Protection can help to protect the cloud-native application from being infected by malware or malicious codes. McAfee provides ultimate protection from malware or antiviruses if you will install it on your device. So, investing in security solution programs may be an extra approach to provide security to cloud-native applications.
To sum up, we have discussed cloud-native applications and their security challenges. The tips and tricks are mentioned to strengthen the security of cloud-native applications. However, there is an additional way by approaching which you will be able to avoid hacking or cyber-criminal activities to the cloud-native applications. The use of antivirus software or a holistic security program can help you to prevent the attack of malware or malicious codes that can be a perfect partner to overcome cloud-native security challenges.
