Within one country it is a combination of cloud and enterprise security systems, their warranties and agreements. That is a combination of technical and judicial means. Usually, software security plays a very decisive role. Companies producing/exploiting this type of security software products never accept any responsibilities and sell/utilize software as is, while making reservations in license agreements that they will collaborate and strive to fix/remove any deficiencies, if they are encountered.

The situation is to some extent similar to security of keeping your money on a bank account - it's quite safe there but the money may be drastically depreciated through a quick inflation process. In such cases, banks aren't responsible, but the money security is somewhat insufficient from depositors' point of view.

Legal and contractual issues

https://en.wikipedia.org/wiki/Cloud_computing_security#Legal_and_contractual_issues

Aside from the security and compliance issues enumerated above, cloud providers and their customers will negotiate terms around liability (stipulating how incidents involving data loss or compromise will be resolved, for example), intellectual property, and end-of-service (when data and applications are ultimately returned to the customer). In addition, there are considerations for acquiring data from the cloud that may be involved in litigation.[45] These issues are discussed in service-level agreements (SLA).

The responsibility for ensuring the security of enterprise resources hosted on the cloud is a shared responsibility between the cloud service provider and the client.

Cloud service providers are responsible for the security of the cloud infrastructure, which includes physical security, network security, and other cloud-specific security controls. However, they may not be responsible for the security of the data and applications that are hosted on the cloud. In general, the security responsibility model is based on the type of cloud service model being used, i.e., Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS).

On the other hand, clients are responsible for the security of their data and applications that are hosted on the cloud. This includes implementing access controls, monitoring for security incidents, and enforcing security policies. Clients are also responsible for educating their users on the importance of online security etiquette and enforcing best practices.

In summary, both cloud service providers and clients have a shared responsibility to ensure the security of enterprise resources hosted on the cloud. Clients should be aware of their responsibility and take appropriate measures to secure their data and applications, while cloud service providers should provide a secure infrastructure and tools to help their clients secure their resources.

Securing enterprise resources is a shared responsibility that typically involves both the service providers and the clients. This is often referred to as the Shared Responsibility Model.

However, it's worth noting that these responsibilities can vary depending on the specifics of the service agreement. For instance, with Infrastructure as a Service (IaaS), the client is typically responsible for more layers of the technology stack, such as the operating system and application security. In contrast, with Software as a Service (SaaS), the provider usually takes on more responsibility, such as application security, because the client is only managing their own data and user access.

That said, the ultimate responsibility for the security of an enterprise's resources rests with the enterprise itself. It's incumbent upon the enterprise to ensure they understand the shared responsibility model and are actively managing the portions of security that fall within their domain. It's also vital that they select service providers who take their portion of the security responsibility seriously and offer the tools and capabilities the enterprise needs to keep their data secure.

Finally, to ensure all-round awareness, the organisation must have a robust security awareness program that educates all stakeholders, including employees, about the importance of security and the role they play in keeping enterprise resources secure. The program should be reinforced regularly and updated to address emerging threats and new technologies.

For enterprise resources hosted in the cloud and related security problems, numerous stakeholders share responsibility for resource security knowledge, implementation, and enforcement. Both CSPs and clients are included. This is how duty is usually split:

1. Cloud Service Providers (CSPs): - Infrastructure Security: Security of cloud services' infrastructure falls to CSPs. Data centre security, network security, and cloud service hardware and software security are included.

Compliance and Certifications: CSPs must follow industry standards and provide clients with compliance certifications like ISO 27001, SOC 2, and GDPR.

CSPs should offer encryption, access restrictions, firewalls, and intrusion detection systems.

Transparency & Communication: CSPs must disclose their security practises and notify clients of any security issues.

2. Cloud Service Clients: - Security Policy and Governance: - Clients establish and enforce security policies and governance structures. Who can use what resources and how.

Clients should instruct staff on online security etiquette and best practises. Know about phishing attempts, protect sensitive data, and comprehend the cloud computing shared responsibility paradigm.

Data security and encryption: CSPs provide the technologies, but clients must apply data encryption, manage encryption keys, and secure sensitive data.

Access Control and Identity Management: Clients must manage user identities and access rights to restrict cloud resource access to authorised users.

Regular Audits and Compliance Checks: The client must routinely audit their cloud resources to verify compliance with internal and external requirements.

3. Shared Responsibility Model: - The "Shared Responsibility Model." is well-established in cloud computing. According to this approach, CSPs are responsible for cloud infrastructure security, while clients are responsible for cloud security (including data and application security).

4. Effective cloud security involves continual collaboration and communication between CSPs and clients. The parties should collaborate to understand and apply best practises and respond quickly to security problems.

In conclusion, service providers and clients are vital to cloud-hosted enterprise resource security. Maintaining a secure cloud environment requires both parties to understand their roles and collaborate.
