Session presented at the 2nd IndicThreads.com Conference on Cloud Computing held in Pune, India on 3-4 June 2011. http://CloudComputing.IndicThreads.com Abstract:As part of this session I intend to provide a technical overview of how cloud computing can be made secure across various networks architectures and deployments such as (a) Security in public cloud deployments – data and application security. This will cover methods such as data encryption, multi tenancy, data wipeout, what type of data to place in public clouds, autentication methods. (b) Security by using public/private mix hybrid cloud deployments. This will cover using hybrid clouds effectively to segregate some portions of data in the public and some in hybrid and how a request can be moved across these. It would also cover options for enterprises to make their solutions secure. (c) Security features provided by current cloud vendors. (d) How a cloud deployer can ensure the solution they are providing is secure. Key Takeaway after this session: An understanding of various security solutions that developers, deployers, architects can use when using cloud computing solutions Speaker: Debashis Banerjee is a technology professional with 12+ years of expertise in development and leading global teams in development of Cloud, Security, Internet based and Telecom products. He is currently a Senior Engineering Manager with Yahoo! India.

4. Cloud Computing - Refresher
• Key aspects of using the cloud: Elasticity, On Demand,
Multi Tenancy, Multi Device, Ability to measure
Service
• Type of Clouds - Public Clouds, Private Clouds,
Hybrid Clouds, Community/Partner Clouds
• Deployment models : SaaS , PaaS , IaaS

5. Key questions to ask about security?
• What do you need to protect? Who are your users?
• Where does your data live? How does it flow? What
geographies?
• What are your compliance, logging needs?
• Is there SSO and Identity management in place?
• Do you have a mix of physical , virtual, cloud?
• Who pays for security? Who is accountable for what aspect of
• security?
• How do you react if a security breach takes place?

7. Security in Public Cloud Deployments
• Strong Identity management
• Privileged Account Management
• Place the appropriate type of data in the cloud
• Have access to compliance and logging , auditing
• Being a public cloud ensure you impose where you data can or
cannot travel
• Wipeout policies
• Ensure you are comfortable with the security of multi tenancy
• Secure keys

8. Security in the Private & Hybrid Cloud
Private:
• Design such that there is scope to move to a hybrid model
• Impose SSO
Hybrid:
• Segregate your data between clouds
• Use SAML and ensure appropriate enterprise credentials are
within the perimeter
• Have your Federation set up correctly. Enable SSO.
• Ensuring enterprise credentials do not travel into the cloud

9. Multi Device Cloud Security – Mobile
Phones
• The mobile device as an extension of the Cloud
• Secure Mobile Apps on the cloud.
• On Cloud and On Device virus scanning
• Seamless policies for mobile devices
• Credential life cycle management
• Secure Roaming Users

10. Multi Factor Auth – OTPs, SMS based
Use OTPs effectively to protect your data access to the cloud

11. Some APIs useful in cloud security
• Safe Browsing API
• VM Safe APIs

12. In Conclusion
• Cloud Security is critical to succeed in the cloud
• Choose Private / Public / Hybrid cloud & SaaS / PaaS / IaaS
• Identity & Privileged User Management
• Compliance, Certification and Logging
• Consider Multi Device Scenarios
• Use Strong Authentication
