Cloud Native Security for Cloud Applications
Given the increasing adoption of cloud-native applications and data, it’s more important than ever to ensure that your cloud infrastructure is secure. Cloud-native applications are a new breed of applications that are designed specifically for the cloud. They are built from the ground up with security in mind.
By leveraging the cloud’s inherent security features, they can help you keep your data safe and secure. On the other hand, although traditional applications (usually referred to as monoliths) can be ported to the cloud, they are not necessarily optimized for them. This means that they may not be able to take advantage of the cloud’s unique capabilities, which can put your data at risk. This challenge can be eradicated by a thorough security review completed to plug security holes and the application being properly refactored to run on the cloud.
We will explore four main components of cloud native security (Kubernetes cluster, container, cloud, code), and some of the most common security risks associated with cloud-native applications and offer best practices for mitigating those risks.
In this blog post, we will explore some of the most common security risks associated with cloud-native applications, along with four main components of cloud-native security (Kubernetes cluster, container, cloud, code), and offer best practices for mitigating those risks.
There are a number of cloud native security risks associated with running applications in the cloud. These include:
Cloud Native Security Risks
Data Breaches
One of the most common security risks associated with cloud computing is data breaches. Because data is stored remotely in the cloud, it is more vulnerable to attack than if it were stored on-premises. To mitigate this risk, organizations should encrypt their data both at rest and in transit. They should also utilize multiple layers of security, including firewalls and intrusion detection/prevention systems.
Insider Threats
Another common security risk is insider threats. This is when employees or contractors misuse their access to cloud resources for malicious purposes. To mitigate this risk, organizations should implement the least privilege principles, which state that users should only have the permissions they need to perform their job function. They should also utilize activity monitoring tools to detect unusual behavior that could indicate an insider threat. Finally, they should have policies and procedures in place for dealing with potential insider threats.
Denial-of-Service Attacks
A denial-of-service attack (DoS attack) is a type of attack where an attacker attempts to prevent legitimate users from accessing a service or resource. This is typically accomplished by flooding the target with requests that overwhelm its capacity to respond. To mitigate this risk, organizations should implement rate limiting and request throttling mechanisms. They should also have contingency plans in place for dealing with DoS attacks, such as using alternative sites or requesting additional capacity from their Cloud Service Provider (CSP). Other effective mitigation strategies include Geographic DNS load balancing and Anycast routing.
Main Components of Cloud Native Security
Below is a quick introduction to four main components of cloud-native security that need to be addressed when considering cloud security measures.
Kubernetes Cluster
A Kubernetes cluster is a group of servers that are used to run containerized applications. Kubernetes is a popular open-source orchestration tool for managing containerized workloads and services. In order to secure your Kubernetes cluster, you need to ensure that all communication between the server nodes is encrypted and that each node has been properly configured. You also need to deploy a network policy to control traffic in and out of the cluster.
Container
A container is a lightweight alternative to a virtual machine. To ensure that your containers are secure, you should use a tool like Docker Hub for image discovery and distribution. Also, make sure that you’re using images from a trusted source and that you’re running them with the appropriate privileges. Create user-specific containers with limited privileges. In addition, you should encrypt all data at rest and in transit within containers. Finally, you should deploy containers in a clustered environment using tools like Kubernetes
Cloud
A cloud is a group of remote servers that are used to store, manage, and process data. To ensure that your data is secure in the cloud, you should encrypt all data at rest and in transit within the cloud infrastructure. You should also use access control measures such as role-based access control to restrict access to sensitive data. In addition, you should implement activity monitoring to detect unusual or unauthorized activity within the cloud infrastructure. Finally, you should apply patches and updates to the cloud software on a regular basis.
Code
To ensure that your application code is secure, you should follow best practices such as writing code with security in mind and using automated static analysis tools to identify vulnerabilities early in the development process. In addition, you should protect secrets such as API keys by storing them in environment variables or using a secrets management tool like Hashicorp Vault. Finally, you should review code changes before they are deployed to production systems.
Conclusion
Cloud-native security is a complex issue, but one that needs to be given careful consideration due to its importance. Data breaches, insider threats, and denial-of-service attacks are just some of the risks that organizations need to be aware of when running applications in the cloud.
By encrypting data, implementing least privilege principles, and utilizing activity monitoring tools, organizations can help mitigate these risks and secure their Cloud Native Applications.
