Cloud Computing Architecture. It allows us to create, configure, and customize the business applications online. These platforms provide basic security features including support for authentication, DoS attack mitigation, firewall policy management, logging, basic user and profile management but security concerns continue to be the number one barrier for ent… Although encryption helps to protect data from any unauthorized access, it does not prevent data loss. These models require customer to be responsible for security at different levels of service. The Defense Information Systems Agency’s (DISA) Secure Cloud Computing Architecture (SCCA) is a set of services that provides the same level of security the agency’s mission partners typically … Some of the security issues related to Service Provider Layer are Identity, Infrastructure, Privacy, Data transmission, People and Identity, Audit and Compliance. This problem is overcome by cloud hosting. Understand the cloud service provider's system about data storage and its transfer into and out of the cloud. The cloud storage system returns the data to the broker. Cloud computing architecture is a combination of service-oriented architecture and event-driven architecture.. Delivery of software on demand 5. This … Analysis of data 6. Data in cloud should be stored in encrypted form. So the data in the cloud should have to be stored in an encrypted form. We can broadly divide the cloud architecture into two parts: Each of the ends is connected through a network, usually Internet. Cloud infrastructure consists of servers, storage devices, network, cloud management software, deployment software, and platform virtualization.. Hypervisor. It is the responsibility of the back end to provide built-in security mechanism, traffic control and protocols. Since data stored in cloud can be accessed from anywhere, we must have a mechanism to isolate data and protect it from client’s direct access. It is rather difficult to talk about cloud security architecture without first talking about the operational model. This document presents the NIST Cloud Computing Reference Architecture (RA) and Taxonomy (Tax) that will accurately communicate the components and offerings of cloud computing. The following diagram shows the graphical view of cloud computing architecture: Front End All of the above steps are shown in the following diagram: Encryption helps to protect data from being compromised. OpenSecurityArchitecture (OSA) distills the know-how of the security architecture community and provides readily usable patterns for your application. Moving upwards, each of the service inherits capabilities and security concerns of the model beneath. Before deploying a particular resource to cloud, one should need to analyze several aspects of the resource such as: 1. This book starts with a quick introduction to cloud native architectures that are used as a base to define and explain what cloud native architecture is and is not. With Cloud Computing, you have access to computing power when you needed. The term cloud refers to a network or the internet. Since then, cloud computing has been evolved from static clients to dynamic ones from software to services. Hosting blogs and websites 4. 3. Hypervisor is a firmware or low-level program that acts as a Virtual Machine Manager.It allows to share the single physical instance of cloud resources between several tenants. A fundamental reference point, based on the NIST definition of Cloud Computing, is needed to describe an overall framework that can be used government-wide.

Select resource that needs to move to the cloud and analyze its sensitivity to risk. Streaming … Reliability and Availability Most of the businesses are dependent on services provided by third-party, hence it is mandatory for the cloud systems to be reliable and robust. We can broadly divide the cloud architecture into two parts: Front End; Back End; Each of the ends is connected through a network, usually Internet. The proxy forwards the request to the broker. What is the Secure Cloud Computing Architecture? Prerequisites Knowledge of cloud computing is essential to understand the environment and its architecture. Lock In It is very difficult for the customers to switch from one Cloud Service Provider (CSP) to another. IaaS has the least level of integrated functionalities and integrated security while SaaS has the most. It is a set of control-based technologies & policies adapted to stick to regulatory compliances, rules & protect data application and cloud technology infrastructure. Finally the proxy sends the data to the client. It protects data that is being transferred as well as data stored in the cloud. Controls in the CA series increase in importance to ensure oversight and assurance given that the operations are being "outsourced" to another provider. Although the cloud computing vendors ensure highly secured password protected accounts, any sign of security breach may result in loss of customers and businesses. The data can be anything such as files, images, documents, audio, video, and more. Before deploying a particular resource to cloud, one should need to analyze several aspects of the resource such as: Select resource that needs to move to the cloud and analyze its sensitivity to risk. Cloud Security Alliance (CSA) stack model defines the boundaries between each service model and shows how different functional units relate to each other. This model describes the security boundaries at which cloud service provider's responsibilities end and the customer's responsibilities begin. Cloud Computing architecture comprises of many cloud components, which are loosely coupled. The server employs certain protocols known as middleware, which help the connected devices to communicate with each other. Services provided by the Cloud Computing environment are not under direct control and therefore a few control families become more significant. Storage, back up, and recovery of data 3. Each of the ends are connected through a network, usually via. However, cloud computing has increased the requirement for network perimeters to be more porous and many attackers have mastered the art of attacks on identity system elements (which nearly always bypass network controls). SECURITY ARCHITECTURE OF CLOUD COMPUTING The components of service provider are SLA monitor, metering, Resource provisioning, Scheduler & Dispatcher, load Balancer. Developing new applications and services 2. Security in cloud computing is a major concern. Consider the cloud type to be used such as public, private, community or hybrid. Iaas is also known as Hardware as a Service (HaaS).It is one of the layers of the cloud computing platform. Visibility into the cloud … Cloud Computing can be defined as delivering computing power( CPU, RAM, Network Speeds, Storage OS software) a service over a network (usually on the internet) rather than physically having the computing resources at the customer location. When the client issues request to access data: The client data request goes to the external service interface of proxy. Cloud Computing as per NIST is, “Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” Management Software 2 Agenda • Background: Cloud Computing • Threats to Cloud Security • Insider Threats in the Cloud • Present, Past, and Future Attacks • Threats to Cloud Security 2.0 • Future Research It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. It is a technology that uses remote servers on the internet to store, manage, and access data online rather than local drives. Cloud computing architecture consists of many loosely coupled cloud components. A particular service model defines the boundary between the responsibilities of service provider and customer. Since all the data is transferred using Internet, data security is of major concern in the cloud. Cloud application developers and devops have been successfully developing applications for IaaS (Amazon AWS, Rackspace, etc) and PaaS (Azure, Google App Engine, Cloud Foundry) platforms. There are the following operations that we can do using cloud computing: 1. To restrict client from accessing the shared data directly, proxy and brokerage services should be employed.
