Cloud Computing & Security Concerns
- 1. Cloud Computing Services & Security Concerns for Data Storage
- 2. AGENDA What is Cloud Computing? Cloud Services and Deployment Models Why all the hype?? Security risks Future of the Cloud Computing Summary
- 3. What is Cloud Computing According to NIST ‘ Cloud computing is a model for enabling 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.’ According to Gartner ‘ Gartner defines cloud computing as a style of computing in which massively scalable IT-related capabilities are provided "as a service" using Internet technologies to multiple external customers’
- 4. Cloud Service Models The Cloud Service models are Cloud Software as a Service (SaaS) – no purchase of software, rent it and pay per use model Cloud Platform as a Service (PaaS) – development platform is offered as service Cloud Infrastructure as a Service (IaaS) – provides entire infrastructure, storage, networking, backup. Other type of models according to Juniper Networks Cloud Data as a Service (Daas) Identity and Policy Management as a Service (IPMaas) Cloud Network as a Service (Naas)

- 6. Cloud Deployment Models Private Cloud Internal cloud solely dedicated to single Organization. Security management managed by internal IT Public Cloud Owned by vendor, available to the public. Offered to multiple customers from common infrastructure Hybrid Cloud Runs non-core application in public cloud and sensitive data in private cloud
- 7. Why all the hype? Cloud Computing is internet based, real-time service and can access solution regardless of location It is massively scalable with flexible business model Provides a flexible pricing model, with a low upfront cost for both infrastructure and software End up being less maintenance, promoting energy efficiency (Green IT) and cost benefits. A recent survey conducted by Pew Internet showed that 69% of all Americans use cloud-based software to store pictures, videos, emails, calendars and other various data online http://www.pewinternet.org
- 8. Security Risks Security, timely availability and reliability of the data on cloud computing is the main concern Unplanned outages (Amazon S3 cloud service went down, 2008) Data recovery refer SLA’s / Cloud provider Google’s Apps users faced slow service, April 2009 Data location and Storage, there are jurisdictions involved Is it secured properly all the private and confidential information. Located in different geographic location, what are the ramification of laws for foreign entity.
- 9. Security Risk Management According to Mather, Kumaraswamy & Latif, 2009, research some of the standards to be used for Security Management in Cloud Computing Services: ITIL ISO/IEC 27001 and 27002. Cloud Services secure areas covered are: Availability management, Vulnerability Management, Access Control, Patch management, Configuration management, Incident response & System use and access monitoring
- 10. According to Gartner 25 Percent of new business Software will be delivered as Software as a Service (Saas) by 2011. http://www.gartner.com/it/page.jsp?id=496886 Cloud Security Alliance is a not-for-profit organization providing security assurance for Cloud Service. Jericho Forum working on getting secure collaboration for cloud computing for individual business needs. Federal CIO is a huge cloud Proponent. Many Cloud pilot programs with in the govt.Washington DC uses Google apps, twitter, you tube
- 11. Summary Cloud Computing is going to be around, accept it! Always understand the Service level agreements (SLAs) of Cloud Service providers, to understand the uptime and downtime Cloud Service is in IT security department and be due diligent. Users should consider what type of data to be used for cloud storage Cost savings can be huge, but be aware of security and governance issues

Editor's Notes
- #4: IT services – on demand, pay per service, internet delivery, etc
- #5: For IaaS model. Consumer must be in complete control of the geographic location of infrastructure and what runs on the server
- #6: From “ Characterizing Intrusion Detection Sensors” by Shaikh, A. S., Chivers, H., Nobles. P., & Clark. A.J. 2008, Network Security p.10 Copyright 2008
- #7: Customer have higher degree of control and transparency, comply with security standards, regulatory compliance Customer of public cloud has a low degree of degree, since security management are done by vendors Hybrid cloud combination of two or more type of clouds
- #8: -Scalability, as in flexible business model according to the size of the organization -Pay for use model. -less maintenance as in patches and updates, in this virtualized environment. Increased automation also saves cost. Flexibility and the ownership /operation of hardware all getting outsourced. . If you’ve ever used MySpace, Facebook, LinkedIn, Picasa, Flickr, Hotmail, or Gmail, then you’ve used cloud computing
- #9: concern is to trust that a company's or an individual's information is both secure and private Unplanned outages - Understanding the cloud provider’s disaster recovery and business continuity measures, negotiating strong service level agreements and disaster recovery commitments, A major concern with cloud computing is the difficulty of determining where data will be stored, and, thus, what courts have jurisdiction and what law governs the use and treatment of such data (i.e., local, state, federal, foreign, etc.). For the location of data you wouldn’t know where it is located too
- #11: Jericho Forum and CSA joined forces to push for technology to allow business , to collaborate securely in the cloud.
- #12: - Categorize data for private and public cloud – basic usage of data and requirement.
