    • About me & Submission details Parveen Yadav Security Researcher aka Ethical Hacker . Working as a Freelancer . White Hat Hacking work. Few Recognitions :- Got listed my name in Google Hall of fame,Amazon,Paypal,Adobe & Few others. Paper Title :- Cloud Computing & Security .
    • Cloud Computing
    • What is Cloud Computing ? Cloud Computing is a technology used to provide: Ease of access to user data, programs and security Services anytime and anywhereServices anytime and anywhere Ensuring complete reliability and security Reduces the cost of work..least possible expenditure
    • BASIC Characteristics of Cloud Computing Multi-tenancy Resources in cloud systems can be shared among a large number of users. Improve the efficiency of cloud systems and save cost for cloud service providers.
    • .. Scalability Even when the total work load for a cloud system increases dramatically, the system could improve its capacity by adding more hardware to handle the increased loadhardware to handle the increased load effectively
    • .. Elasticity A cloud system only delivers the minimum amount of computing resources that meet users’ need. The amount of resources provided to users increase when they need more, andto users increase when they need more, and decrease when they need less. Users only pay for whatever they consumed.
    • .. Device Independent Users can utilize cloud services using whatever device they have, should it be a laptop, an iPad or a smartphone, as long as they have access to the Internet.they have access to the Internet.
    • .. Low-cost Computing resources are provided by cloud systems. Users do not need to purchase expensive computers to perform tasks that need high performanceto perform tasks that need high performance computing.
    • .. Reliability Multiple redundant sites are used in cloud systems. There are always backups available when one or more sites are down.more sites are down.
    • History of cloud computing Evolution The idea of cloud computing dates as far back as the 1960’s when John McCarthy envisioned a time when computation may someday be orgainsed as a public organisation. Cloud computing has evolved through a number of phases which include grid and utility computing ,application service processing(ASP),software as a service (Saas)
    • Grid Computing a form of distributed computing,acting in concert to perform very large tasks. Utility Computing a metered service similar to a traditional public utility such as electricity.
    • Cloud Computing is an Evolution in IT 4
    • Major services Major Services Few other types of Clouds Network as a Service (NaaS) Storage as a Service (STaaS) Security as a Service (SECaaS) Data as a Service (DaaS) API as a Service (APIaaS)
    • Cloud Service Models Software as a Service (SaaS) Service provider’s apps User’s do not manage the Network, Servers, OS, Storage or applications by the user Platform as a Service (PaaS) User deploys their apps on the cloudUser deploys their apps on the cloud Controls their apps User’s do not manage Servers, IS, Storage Infrastructure as a Service (IaaS) User’s get access to the infrastructure to deploy their content Doesn’t manage or control the infrastructure Does manage or control the OS, storage, apps, selected network components.
    • Cloud Deployment models Public Cloud computing environment are open for use to anyone who wants to sign up and use them. These are run by vendors and applications from different customers are likely to be mixed together ondifferent customers are likely to be mixed together on the cloud’s servers, storage systems, and networks. Examples of a public cloud: Amazon Web Services and Google's AppEngine .
    • A private cloud is basically an organization that needs more control over their data than they can get by using a vendor hosted service. A hybrid cloud combine both public and private cloud modelscloud models.
    • Google Docs A cloud based online Office Allow you to create, edit and share documents online using web browsers, iPads or even smart phones.even smart phones. https://docs.google.com/demo/edit?id=scAAVln2yf3it2VCiVf- DUzGg&dt=document#document
    • Amazon Cloud Drive Amazon Cloud Drive is an personal hard drive in a cloud system. Store music, videos, photos, and documents on Amazon's servers. https://www.amazon.com/clouddrive documents on Amazon's servers.
    • Dropbox cloud provider Dropbox is a file hosting service that offers cloud storage,file synchronization & client software. It allows users to create a special folder on each of their computers,which dropbox then synchronizes so that itcomputers,which dropbox then synchronizes so that it appears to be in the same folder regardless of which computer is used to view it.
    • Rate/Price of Cloud Services
    • How Cloud Works :-
    • Opportunities and Challenges The use of the cloud provides a number of opportunities: It enables services to be used without any understanding of their infrastructure. It potentially lowers the outlay expense for start upIt potentially lowers the outlay expense for start up companies, as they would no longer need to buy their own software or servers. Cost would be by on-demand pricing. Data and services are stored remotely but accessible from “anywhere”. 22
    • Advantages Of Cloud Computing Lower total cost of ownership. Always on, Always available. Faster application delivery. Improved business continuity. Platform for easier and faster sharing, mobilePlatform for easier and faster sharing, mobile workforce. Rental pricing model. Pay-as–you-go, Try before you buy. Lower Infrastructure Cost .
    • Disadvantages Of Cloud computing Security issue Data Loss Risks Privacy policies But can we tackle it……How???43% of current cloud users reported a security incident in the past 12 months
    • Cloud Computing-Attacking methods Distributed Denial of Service Attacks (DDoS) . Authenticated Risks. Data Segregation Risks. Web-application Attacking methods.Web-application Attacking methods.
    • Distributed Denial of Service Attacks Distributed Denial of service (DDoS) attacks means many node systems attacking one node all at the same time with a Flood of useless messages to exhaust Web Server’s resources .
    • Authenticated Risks Authentication is a weak point in a hosted & virtual service’s and frequently targeted. Ways to check the Authenticity of the client : Leverage strong two –factor authentication techniques. Use of static I.P, Virtual I.P techniques . Designated Emplyoee’s Access .
    • Data Segregation Risks Data segregation is not easily facilitated in all cloud enviornments as all the data can’t be segregated acc. To the user needs.Some customers do not encrypt the data as there are chances for the encryption itself to destroy the data . The compromised servers are shut down whenever a data is needed to be recovered.The available data is not correctly sent toneeded to be recovered.The available data is not correctly sent to the customer at all times of need. When recovering the data there could be instances of replication of data in multiple sites.
    • How to safeguard your Cloud Database
    • Cloud computing & parameter security firewall .
    • Few things to know before choosing ..... Select the right Cloud service provider . Cloud provider Location. Market value of cloud provider. Pre-Examination Test .
