Topic Overview  Introduction  Cloud Basics  Securing the Cloud  Leveraging the Cloud  Final Recommendations
Introduction  Cloud Computing Industry is growing  According to Gartner, worldwide cloud services revenue is on pace to surpass $56.3 billion in 2009, a 21.3% increase from 2008 revenue of $46.4 billion, according to Gartner, Inc. The market is expected to reach $150.1 billion in 2013.  Businesses are increasing Cloud adoption  "We expect a great deal of migration towards cloud computing within the federal government in addition to the already robust private sector growth. The growth of the cloud should not outpace our ability to protect the data that goes into it..." ~ Former White House advisor Paul Kurtz, partner with Good Harbor Consulting, LLC  How can IT leaders ensure security in the

Securing the Cloud  Security Interaction Model  Top Security Threats  Cloud Provider Security Practices – Google Case Study
Security Interaction Model
Top Security Threats  Abuse and nefarious use of cloud computing  Insecure interfaces & API’s  Unknown risk profile  Malicious insiders  Shared technology issues  Data loss or leakage  Account or service hijacking
Abuse and nefarious use of cloud computing  Stricter initial registration and validation processes.  Enhanced credit card fraud monitoring and coordination.  Comprehensive introspection of customer network traffic.  Monitoring public blacklists for one’s own network blocks. Insecure interfaces & API’s  Analyze the security model of cloud provider interfaces.  Ensure strong authentication and access controls are implemented in concert with encrypted transmission.  Understand the dependency chain associated with the API. Unknown risk profile  Disclosure of applicable logs and data. Partial/full disclosure of infrastructure details  Monitoring and alerting on necessary information. Threat Mitigation
Malicious insiders  Enforce strict supply chain management and conduct a comprehensive supplier assessment.  Specify human resource requirements as part of legal contracts.  Require transparency into overall information security and management practices, as well as compliance reporting.  Determine security breach notification processes. Shared technology issues  Implement security best practices for installation and configuration.  Monitor environment for unauthorized changes/activity.  Promote strong authentication and access control for administrative access and operations.  Enforce service level agreements for patching and vulnerability remediation.  Conduct vulnerability scanning and configuration audits. Threat Mitigation
Data loss or leakage  Implement strong API access control.  Encrypt and protect integrity of data in transit.  Analyze data protection at both design and run time.  Implement strong key generation, storage and management, and destruction practices.  Contractually demand providers wipe persistent media before it is released into the pool.  Contractually specify provider backup and retention strategies. Account or service hijacking  Prohibit the sharing of account credentials between users and services.  Leverage strong two-factor authentication techniques where possible.  Employ proactive monitoring to detect unauthorized activity.  Understand cloud provider security policies and SLAs. Threat Mitigation
Google Security Practices  Organizational and Operational Security  Data Security  Threat Evasion  Safe Access  Privacy
Google Organizational and Operational Security  Holistic approach to security  Security team  Develop with security in mind  Regularly performs security audits and threat assessments  Employees screened, trained  Works with security community and advisors
Google Data Security  Google Code of Conduct – “Don’t be evil.”  Physical security  Logical Security  Accessibility  Redundancy
Google Threat Evasion  Spam and virus protection built into products  Protects against application & network attacks
Google Safe Access  Avoids local storage  Access controls  Encrypted connections  Integrated security
Google Privacy  Privacy policy  Does not access confidential user data  Does not alter data  Maintain own IP rights  Indemnification, liability  End of use
Leveraging the Cloud  Decision Making Process  Clan Wars Case Study
Decision Making Process  Identify the asset for cloud deployment  Evaluate the asset requirements for confidentiality, integrity, and availability  Map the asset to potential cloud deployment models  Evaluate potential cloud service models and providers  Sketch the potential data flow  Draw conclusions
Case Study: Clan Wars Company Profile Online multiplayer game In Browser Flash Processes credit card payments
Case Study: Clan Wars Decision Making Process  Identified all components as candidates  Evaluation concluded:  Payment = High concern on all factors  Game & data = Medium on all factors  Primary components mapped:  Infrastructure (Servers, storage, etc)  Payment Processing  Collaboration
Case Study: Clan Wars Data Flow
Case Study: Clan Wars Conclusion Great fit Risk requirements met Data flow supports needs Added benefits Low cost (saving ~$500/month) Low maintenance Performance
Final Recommendation No universal answer Evaluate your security needs versus the capabilities of the provider
