Guidelines on security and privacy in public cloud computing

Abstract

The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST) promotes the U.S. economy and public welfare by providing technical leadership for the Nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analysis to advance the development and productive use of information technology.ITL's responsibilities include the development of technical, physical, administrative, and management standards and guidelines for the cost-effective security and privacy of sensitive unclassified information in Federal computer systems. This Special Publication discusses ITL's research, guidance, and outreach efforts in computer security, and its collaborative activities with industry, government, and academic organizations.Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for the purpose. National Institute of Standards and Technology Special Publication 800-144 80 pages (December 2011)iv AbstractCloud computing can and does mean different things to different people. The common characteristics most interpretations share are on-demand scalability of highly available and reliable pooled computing resources, secure access to metered services from nearly anywhere, and displacement of data and services from inside to outside the organization. While aspects of these characteristics have been realized to a certain extent, cloud computing remains a work in progress. This publication provides an overview of the security and privacy challenges pertinent to public cloud computing and points out considerations organizations should take when outsourcing data, applications, and infrastructure to a public cloud environment.

Cloud Computing: Information Security Concerns

“…NIST в своей специальной публикации [7] выделяет три модели облачных вычислений: инфраструктура как сервис (IaaS), платформа как сервис (PaaS) и программное обеспечение как сервис (SaaS); при этом для каждого типа управление данными меняется.…”

“…Однако провайдеры не спешат брать на себя ответственность за безопасность данных [6]. При передаче данных в облако владелец практически лишается возможности контролировать их безопасность [7].…”

Public cloud computing for Software as a Service platforms

“…Security in cloud-based systems is frequently mismanaged -in order to maximize effectiveness while also minimizing costs as well as the risk of security breaches, security and privacy must be considered from the initial planning stage at the beginning of the system development life-cycle. Addressing security issues after implementation and deployment is not only much more difficult and expensive, but also considerably riskier [10].…”

IT controls in the public cloud: Success factors for allocation of roles and responsibilities

“…In order to analyse the management of IT controls in a cloud environment, it is necessary to evaluate cloud computing deployment and services models. The management of computational resources in an organisation is broadly characterised by the cloud deployment model adopted by the organisation (Jansen & Grance, 2011). A variety of deployment models of cloud services have evolved in the marketplace (Krieger, McGachey, & Kanevsky, 2010;Vanmechelen, Depoorter, & Broeckhove, 2011;Venkatraman, 2013), with public, private, hybrid and community cloud deployment models being the most popular ones.…”
