Learn about enhanced data encryption options, isolate your application runtime for extended security, and use activity logs and security advisors to evaluate app security.

You’ve already developed and deployed an application on IBM Cloud. You’ve already followed the introductory tutorial on how to apply end-to-end security to an application.

Following “security by design,” you are now starting to look into the design of a new application, or perhaps you need to adapt an older application to new security requirements. If that is the case, our new tutorial on how to enhance the security of your deployed application is exactly right for you.

An existing solution is extended for enhanced security.

Isolate resources

One of the fundamental principles of cloud computing is the sharing of resources. This could be the sharing of a machine—applications from many users running on the same computer—or just sharing the data center and parts of the infrastructure. 

In the new tutorial, you’ll learn how you can isolate runtime environments, network traffic, and stored data to increase application security. Some options include the use of dedicated resources or virtual private clouds.

Hyper-protect your data

Almost all services on IBM Cloud that store data use encryption to protect the data against unauthorized access. When using database services or object storage, by default, the encryption key is system-generated. You can increase data protection by controlling the encryption keys. IBM Key Protect and Hyper Protect Crypto Services help you provision encrypted keys for storage services as well as apps.

In the new tutorial, you learn how to control and even bring your own encryption keys. You also find out about the LinuxONE-based Hyper Protect services on IBM Cloud. They provide an extra layer of protection and the highest level of isolation.

Evaluate and monitor app security

Events related to IBM Cloud account activities—such as logging in or provisioning a service—are logged to Activity Tracker with LogDNA. In the tutorial, you learn how to enhance your app to send security or audit messages and integrate them across the stack. Use security advisors and set up notifications to stay ahead and informed.

Get started with the tutorial

The tutorial on how to enhance security of your deployed application is part of the IBM Cloud solution tutorials. It helps you learn about enhanced data encryption options, isolate your application runtime for extended security, and use activity logs and security advisors to evaluate app security.

The advantages and disadvantages of private cloud 

6 min read - The popularity of private cloud is growing, primarily driven by the need for greater data security. Across industries like education, retail and government, organizations are choosing private cloud settings to conduct business use cases involving workloads with sensitive information and to comply with data privacy and compliance needs. In a report from Technavio (link resides outside ibm.com), the private cloud services market size is estimated to grow at a CAGR of 26.71% between 2023 and 2028, and it is forecast to increase by…

Optimize observability with IBM Cloud Logs to help improve infrastructure and app performance

5 min read - There is a dilemma facing infrastructure and app performance—as workloads generate an expanding amount of observability data, it puts increased pressure on collection tool abilities to process it all. The resulting data stress becomes expensive to manage and makes it harder to obtain actionable insights from the data itself, making it harder to have fast, effective, and cost-efficient performance management. A recent IDC study found that 57% of large enterprises are either collecting too much or too little observability data.…
