Q

List key roles of the cloud service customer and activities they are responsible for?

ISO standard that defines the roles and responsibilities of CSC?

A

Cloud architect: Evaluates cloud technologies and services and designs the overall architecture of the cloud deployment to meet organizational requirements.

Cloud service user: Uses services provided by the CSP.

Cloud service administrator: Configures, manages, and monitors the use of cloud services.

1SO17789 CSC Role

18
Q

Key roles and activities performed by the cloud service partner?

A

Cloud auditor: Performs audits of cloud environments and provides audit reports.

Cloud service broker: Provides a marketplace for approved services, manages contracting, and securely integrates cloud services with on-prem applications.

19
Q

IaaS Key Benefits

A

Cost Efficiency - Trade CapEx (capital expenditure) for OpEx (Operational Expenditure); cloud provider pays for managing physical security and energy of data center; reduction of maintenance support and ownership costs

Availability and Reliability - customers can load balance and have redundancy across infrastructure spanning regions

Scalability -additional resources can be procured, provisioned, and expanded quickly and with ease to support growing demand

Metered pay per use

20
Q

PaaS Key Benefits

A

Cost efficiency: Devs pay only for cloud resources they use

Flexibility: Devs can switch between OS and software versions

Simplicity: Infrastructure and OS managed by CSP, so devs don’t have to patch and upgrade OS or libs

Ease of access: Access dev environments from anywhere in the world and makes it easy to collaborate and share information

21
Q

SaaS Key Benefits

A

Cost Efficiency: Eliminates the need for Sys Admins and dedicated HW/SW.

Licensing: Effectively lease or borrow license as software is used, eliminating the need to purchase a full set of licenses. Use discounts realized by CSP, because the CSP has larger scale.

Standardization: Consistent experience for users because cloud provides standardized application, with the latest and greatest versions of software, with little to no action take by customer

22
Q

Public Cloud

A

A set of cloud computing services that can be accessed by anyone willing and able to pay for them; May be owned by business, academic or government organization

23
Q

Public Cloud Benefits

A

Easy to set up and manage
Highly scalable resources
Resource efficiency and cost effective

24
Q

Benefits of Private Cloud

A

Increased Ownership and Governance

High level of system and data control

25
Q

Community Cloud Benefits

A

Mirror public cloud (Easy to set up and and manage, Highly scalable, resource efficiency and cost Effective)

Common set of requirements ensures the cloud meets these requirements

26
Q

Hybrid Cloud Benefits

A

Reuse of existing infrastructure and technology: already have infrastructure from private or community cloud, but want the benefits of public cloud or may have to maintain some private/community cloud for compliance/legal/business reasons

Control over critical or sensitive systems: keep sensitive data in private/community cloud while allowing less sensitive data in public cloud

Disaster recovery support: Benefit from redundancy and reliability assurance of public cloud, for customers that already have private cloud

27
Q

Cloud (service) provider (CSP)

A

An entity making cloud services available for use.

The vendor offering cloud services.

28
Q

Cloud (service) customer

A

A person or group that is in a business relationship to provision and use cloud services from a cloud service provider.
The entity purchasing the cloud services e.g. paying the bill

1SO17789 primary role

29
Q

Cloud (service) user

A

A person or entity (which may be a device, for example) that uses cloud services on behalf of the cloud service customer.

1SO17789 primary Role

30
Q

Cloud service partner (CSN)

A

A person or group that supports the provision, use, or other activities of the cloud service provider, the cloud service customer, or both.

Includes all roles that are not CSC or CSP.

1SO17789 primary Role

31
Q

Cloud Auditor Desc?

What standard and subrole?

A

A cloud service partner who is responsible for conducting an audit of the use of cloud services. An audit may be for general security hygiene, but is often for legal or compliance purposes

Performs an independent examination of the cloud service provider with the intent to verify conformance to standards and/or compliance.

independent = third party

1SO17789 CSN Role

32
Q

CASB

Standard and Type of subrole?

A

Cloud Access Security Broker (CASB) A third-party entity offering independent identity and access management (IAM) services to CSPs and cloud customers, often as an intermediary. This can take the form of a variety of services, including single sign-on, certificate management, and cryptographic key escrow.

1SO17789 CSN Role

33
Q

Cloud (service) broker

Standard and Type of subrole?

A

A cloud service partner who negotiates relationships between cloud service providers and cloud service customers.

An individual or company that purchases services from a cloud provider, who adds value then resells them to its own customers.

1SO17789 CSN Role

34
Q

What does a CSB likely prevent?

A

Vendor Lock In because they should abstract proprietary implementation and provide standards based implementation or provides more favorable contract agreements to customer.

35
Q

What does a CSB provide to cloud customer?

A

Service Intermediation - improves specific capability and providing value-added services to cloud customers
Service Aggregation - combines and integrates multiple services into one or more new services
Service Arbitrage - broker has the flexibility to choose services from multiple cloud services providers

36
Q

Cloud Carrier

Is this role part of a security standard? If so which one?

A

Intermediary that provides the connectivity and transport of the cloud services between the cloud customer and cloud provide (ex. ISP)

1SO17789 Role

37
Q

SaaS Delivery Models

A

38
Q

IaaS Components and Characteristics

A

Scalability - support significant demand

Converged network and IT capacity pool - resource pool appears seamless and endless

Self service and on-demand capacity - customer can manage cloud resources without interacting with CSP

High Reliability and Resilience - infrastructure should be reliable and resilient while uphold the SLA

39
Q

PaaS Components and Characteristics

A

Flexibility - plugins can be added to the platform

Support Multiple languages and frameworks

Multiple hosting environments - can migrate from public to private or choose type 1 vs type 2 hypervisor

Ability to autoscale - per requirement (e.g. location)

Allow choice and reduce vendor lock-in

40
