Q4Cloud Computing

Cloud security requirements include: confidentiality — ensuring data is encrypted both at rest (in storage) and in transit (over the network), and accessible only to authorized parties; integrity — ensuring data cannot be tampered with undetected, whether in storage or during transmission; availability — ensuring cloud services remain accessible and resilient against outages, denial-of-service attacks, and hardware failures, typically achieved through redundancy and geographic replication; identity and access management (IAM) — ensuring only properly authenticated and authorized users/services can access specific cloud resources, typically using role-based access control; multi-tenancy isolation — ensuring that different customers sharing the same underlying physical infrastructure cannot access or interfere with each other's data or virtual machines; and regulatory/compliance requirements — ensuring the cloud provider's practices meet relevant legal and industry standards (such as GDPR, HIPAA, or ISO 27001) applicable to the specific data being handled.
