Cybersecurity in Cloud Computing: Threats & Risk Management

May 05, 2025 Digital & Product Solutions / Cyber Security
From startups to global companies, organizations are leveraging the power of cloud computing to scale operations, accelerate innovation and reduce costs. This has not only impacted on the management of the digital infrastructures, but it has also redefined the very foundation of business strategy.
However, this digital transformation comes with a new frontier of cybersecurity challenges. As data migration and the adoption of cloud applications increase, cyber threats and potential vulnerabilities arise. Misconfigurations, unauthorized access and increasingly sophisticated attacks have made cloud environments a prime target for cybercriminals.
From best practices in cloud application security to the most common types of attacks, this article uncovers the role of cybersecurity in cloud computing.

What is Cloud Computing?

Cloud computing is the on-demand delivery of computing services over the internet, providing access to a wide range of resources. It enables technologies to streamline operational efficiency, such as scalable data storage and software that runs on servers which automatically adjust resources based on real-time demand.
Cloud computing brings a comprehensive set of strategic benefits, including:
Scalability
It enables real time resource scaling based on their usage. Let’s analyze this practical example: consider a server hosting a web application that experiences a peak of requests, more than other applications do, during specific hours of the day. As demand increases, resources will increase too in order to provide seamless service delivery.
Cost Efficiency
Accessibility
Despite its advantages, cloud computing also presents security challenges.

Best Practices for Cybersecurity in Cloud Applications

Cloud application security involves securing cloud-based software applications through their development and lifecycle. It is especially important in multi-cloud environments, where the expanding attack surface significantly increases the risk of cyber-attacks.
It’s this growing complexity where the relationship between cloud computing and cloud application security emerges, defined by the “shared responsibility model”. This model states that cloud service providers are responsible for securing the underlying infrastructure, such as physical components, hardware or networks. Organizations, on the other hand, are responsible for everything built on top of that infrastructure, including operating systems and applications.
At this point, Cloud Application Security Assessment (CASA) plays a critical role. CASA is a cybersecurity assessment that provides a structured approach to maintain the security of Google user’s data. It verifies that cloud-based applications have been developed implementing security by design and can manage data securely, aligning with the shared responsibility model.

Cloud Application Security Assessment (CASA): Importance & Impact

This industry-recognized security assessment categorizes cloud and local storage integrations into risk-based tiers, providing clear guidelines and a standardized approach on how to ensure data security for cloud app developers and end users.
DEKRA is one of the 11 authorized testing laboratories of the App Defense Alliance (ADA), bringing together extensive knowledge and a global network of cybersecurity experts to address all your security needs.
Cybersecurity in cloud computing requires a combination of technologies, regulations and proactive measures to enhance the security of data applications, and most important: users. It’s our responsibility to take action to stay ahead of the evolving threats for building a secure and reliable cloud environment for the future.
