Certificate of Cloud Security Knowledge (CCSK) Practice Test

The correct answer is the erosion of trust boundaries that is amplified by cloud computing, identified as re-perimeterization. In the context of cloud security, trust boundaries refer to the established security boundaries that define the levels of access and control over data and resources. Traditional models of security relied heavily on these boundaries, usually defined by firewalls and physical infrastructure. Cloud computing alters this dynamic significantly. As organizations transition to cloud environments, they're often extending their data and services beyond their previously well-defined boundaries. This results in the erosion of trust boundaries, as users and applications interact across disparate systems and locations, leading to greater exposure of sensitive data and increased risk. Re-perimeterization represents the evolving nature of these boundaries in the cloud. Organizations must shift their security perspectives towards embracing a more dynamic and adaptable approach. This includes implementing robust identity and access management, data encryption, and continuous monitoring to redefine and reinforce trust in a more complex landscape. In contrast, decentralization generally refers to distributing resources to avoid single points of failure, virtualization involves creating virtual resources for efficiency, and standardization pertains to uniform practices and protocols that may not directly address the complexities of trust boundaries in cloud environments. Each of these aspects has relevance in the cloud, but they do not specifically encapsulate
