Cyber-attacks are a primary concern for businesses in today’s online environment. A security breach can create incredible financial and asset losses. Companies can lose up to $25 per minute due to data breaches alone. In addition, it can ruin the customer’s trust that their information is safeguarded and spoil the company’s overall reputation.
Now more than ever, organizations utilize cloud infrastructures to store important applications, data, and operations. However, despite all the advances in cloud security, cyber security remains a prominent concern, and businesses continue to look for cloud solutions. Therefore, companies must center DevSecOps in their business processes and strategy for the efficiency of cloud operations and to optimize their data protection.
When selecting a Cloud Service Provider (CSP), it’s crucial to consider the security factors involved during cloud migration and for cloud operations. In this blog, we’ll break down where the responsibility of cloud security lies; then discuss five security factors for consideration when migrating to the cloud and the digital transformation it brings.
Shared Responsibility Model
When developing a cloud migration strategy, you need to consider who is responsible for the different components of the cloud’s security. Depending on the cloud model the company chooses, such as SaaS, IaaS, or PaaS, the company will have varying responsibilities surrounding the environment’s security.
For example, suppose a company is using the Software as a Service (SaaS) model. In that case, the CSP is responsible for the security of the underlying infrastructure; such as the servers and operating systems on which the specific cloud application runs. But the business using the cloud is responsible for access to the application.
If a company uses an Infrastructure as a Service (IaaS) model, they are responsible for the security of the infrastructure, such as the servers, operating systems, and network devices. Here the business must ensure the systems are kept updated and properly configured. With this model, the cloud provider is only responsible for the physical security of the infrastructure.
Despite being aware of the shared responsibilities, the business is always accountable for the security of the data. If there is a compromise, the business is ultimately responsible, not the cloud provider. It’s essential to consider the service level agreements with the CSP to understand who’s responsible for each aspect of the service while assessing and understanding potential security factors.
