In the era of digital transformation, businesses are increasingly leveraging cloud computing services to enhance agility, scalability, and efficiency. However, the paramount concern for organizations considering a move to the cloud is the security of their data and operations. This article delves into the security aspects of the three primary cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

I. Infrastructure as a Service (IaaS): IaaS provides the fundamental building blocks of computing infrastructure, such as virtual ma-chines, storage, and networking. While IaaS offers a high level of control over the underlying infrastructure, security responsibilities are shared between the cloud provider and the customer.

1. Security Control: Customers are responsible for securing their operating systems, applications, and data. Cloud providers manage the security of the physical infrastructure, hypervisor, and network.

2. Customization: IaaS allows organizations to implement their security measures based on specific requirements. Greater control over security configurations and policies.

II. Platform as a Service (PaaS): PaaS abstracts the underlying infrastructure, offering a plat-form that allows developers to build, deploy, and manage applications. The security landscape in PaaS is characterized by shared responsibilities and automated services.

1. Shared Responsibility: Cloud providers manage the security of the underlying infrastructure. Customers are responsible for securing their applications and data.

2. Automated Security Features: PaaS platforms often include built-in security features, such as authentication and encryption. Automatic updates and patches enhance overall system security.

III. Software as a Service (SaaS): SaaS delivers fully functional applications over the internet, eliminating the need for users to manage the underlying infrastructure or application stack. Security in SaaS is a collaborative effort between the provider and the end-users.

1. Provider-Managed Security: Cloud providers handle security measures for the application, data, and infra-structure. Customers rely on the provider’s security protocols.

2. Limited Customization: Security configurations are predefined by the SaaS provider. Customers have minimal control over the underlying security architecture.

Conclusion:

The security of cloud services depends on various factors, including the service model, provider, and the specific security measures implemented by both parties. Ultimately, the choice be-tween IaaS, PaaS, and SaaS should align with the organization’s security requirements, level of control desired, and the resources available for managing security responsibilities. While each model has its strengths and considerations, a comprehensive and well-implemented security strategy is crucial regardless of the chosen cloud service model.

Sophos has compiled a report and released it stating 67% of IaaS cloud providers were hit by ransomware this year and the numbers to increase by a double fold this year. Unpatched vulnerabilities and configuration errors made it easy for hackers to steal info and encrypt data on the servers related to the cloud.

FYI, IaaS is a cloud computing server where an individual or a company offers computing, storage, and networking resources on demand and the user can pay-as-you use model, making it into one of the profitable businesses in the world of computing technology.

Experts from Sophos claim that users usually lack the visibility into the in-house resources and their configurations and it cuts down the ability to detect, investigate and remove threats in their IaaS cloud infrastructure. But isn’t it a workload of the operator or a CSP…?

Coming to the other news, Keralty Multinational Healthcare Organizations based in Columbia released a press update that it became a victim of a ransomware attack disrupting its website and company operations to a certain extent since Sunday.

Because of this malware attack, Keralty’s subsidiaries suffered Colsanitas, Sanitas USA and EPS Sanitas have suffered a cut down to medical records access and thus impact scheduling of medical appointments of over half a million patients from a total count of 6 million.

Unconfirmed sources from the Columbia’s Healthcare provider claim that disruption was caused because of a file encrypting malware attack on a third party that was offering IaaS to the healthcare service provider 371 medical centers spread across Asia, US, Spain and Latin America.
