“…Within the global shift of information technology from organization-internal, on-premise systems to broad usage of cloud services, multi-cloud strategy is arguably seen as a dominating trend for organizations of a certain complexity and size [8,9]. A multicloud strategy selects platforms, infrastructure and applications from different cloud service providers (CSPs), each for a specialized purpose, and integrates them organizationally and technically adapted to the requirements of an organization [10].…”

“…With these preparations, planning workshops were held with a senior staff group of responsible experts from IT and IT security departments. They developed three different models for the participation of external service providers in the SOC 9 . The method of rational consensus was employed again, and the group was asked to provide brief rationales for their decisions.…”

“…The rationales for the valuations are given per SOC main task group below the table. 9 It should be noted that the external entities are always thought of in the plural, although this is not explicit in the models. This allows for further model differentiation including the fact that already employed providers play roles in the SOC, for example as suppliers of know-how (e.g.…”

We present a case study on the strategic planning of a security operations center in a typical, modern, mid-size organization. Against the backdrop of the company’s multi-cloud strategy a distributed approach envisioning the involvement of external providers is taken. From a security-centric abstraction of the organizational IT-landscape, a novel strategic planning method for security operation centers is developed with an adaptable relationship matrix as core tool. The method is put to a practical test in modeling different levels of engagement of external providers in the center’s operation. It is shown that concrete output, such as a core statement of work for an external provider, can easily be derived.

“…Supports Multi-Cloud Environment-The cloud industry's gravitation towards offering support for many different cloud platforms can be attributed to its many advantages. There may be unique features and offerings by disparate CSPs that, when coupled, enhance the business capabilities of CSC, such as maintenance of information, preservation of data confidentiality, management of delicate infrastructure and improvements in performance [56][57][58][59][60]. 7…”

Security of Zero Trust Networks in Cloud Computing: A Comparative Review

Recently, networks have shifted from traditional in-house servers to third-party-managed cloud platforms due to its cost-effectiveness and increased accessibility toward its management. However, the network remains reactive, with less accountability and oversight of its overall security. Several emerging technologies have restructured our approach to the security of cloud networks; one such approach is the zero-trust network architecture (ZTNA), where no entity is implicitly trusted in the network, regardless of its origin or scope of access. The network rewards trusted behaviour and proactively predicts threats based on its users’ behaviour. The zero-trust network architecture is still at a nascent stage, and there are many frameworks and models to follow. The primary focus of this survey is to compare the novel requirement-specific features used by state-of-the-art research models for zero-trust cloud networks. In this manner, the features are categorized across nine parameters into three main types: zero-trust-based cloud network models, frameworks and proofs-of-concept. ZTNA, when wholly realized, enables network administrators to tackle critical issues such as how to inhibit internal and external cyber threats, enhance the visibility of the network, automate the calculation of trust for network entities and orchestrate security for users. The paper further focuses on domain-specific issues plaguing modern cloud computing networks, which leverage choosing and implementing features necessary for future networks and incorporate intelligent security orchestration, automation and response. The paper also discusses challenges associated with cloud platforms and requirements for migrating to zero-trust architecture. Finally, possible future research directions are discussed, wherein new technologies can be incorporated into the ZTA to build robust trust-based enterprise networks deployed in the cloud.

“…The design of extensible providers in the IaC toolchain allows the target environment to be set on either a private cloud based on OpenStack with Magnum, or IaaS clusters of mainstream public clouds. This enables a cloud-native service stack to support hybrid cloud multi-cloud environments [29] for performance and availability.…”

With the widespread acceptance of the cloud-native concept and the emergence of a large number of dedicated cloud-native applications, the service stacks of cloud-native applications have received extensive attention in the industry. To analyze the extensibility problems of service stacks, a cloud-native light-cone model is proposed, which focuses on the dimensions of application, infrastructure, tenant and workflow, and provides a perspective view that reflects the concerns of stakeholders. Based on this model, various challenges in designing extensible cloud-native service stacks are identified by classification. To solve these challenges, a holistic architecture and a set of key technologies are designed, involving unified runtime abstraction, cluster bootstrapped creation, application-specific controllers, etc. Furthermore, the OMStack (Oriental Mind Stack) is implemented, which integrates these technologies and provides a group of PaaS and SaaS services for container cluster (OMCC), artificial intelligence (OMAI), big data (OMBD) and so on. Experimental analysis and production applications demonstrate the practicality, efficiency and reliability of the proposed architecture, stack and services.
