1 Visions of Clouds and Cloud Security Rob Randell, CISSP Senior Security and Compliance Specialist VMware, Inc.

2 Visions of Clouds and Cloud Security What is the Cloud? PAAS SAAS IAAS Chris Hoff s Model of the Cloud Cloud Security Alliance s 15 Domains We will focus on IAAS Virtualization is the Basis Basic Virtualization Overview What is the private cloud? Internal Cloud External Cloud Internal Cloud + External Cloud = Private Cloud Benefits of the Private Cloud Limitations of the Private Cloud Cloud Security Reference Architecture

3 What is the Cloud? X as a Service Types of Clouds Software as a Service (SaaS) Salesforce.com Google Apps Platform as a Service (PaaS) Google App Engine Force.com Infrastucture as a Service (IaaS) Amazon EC2 Rackspace Savvis

4 Security Considerations of Each Type of Cloud Software (SaaS) Least extensibility and greatest amount of security responsibility taken on by the cloud provider Infrastructure (IaaS) Greatest extensibility and least amount of security responsibility taken on by the cloud provider Platform (PaaS) Lies somewhere in the middle, with extensibility and security features which must be leveraged by the customer

5 Cloud Model

6 What This Means To Security Salesforce - SaaS The lower down the stack the Cloud provider stops, the more security you are tactically responsible for implementing & managing yourself. Google AppEngine - PaaS Amazon EC2 - IaaS

7 Cloudanatomy Infostructure! Content & Context - Applications, Information, Services Metastructure! Glue & Guts - IPAM, IAM, BGP, DNS, etc. Infrastructure! Sprockets & Moving Parts - Compute, Network, Storage

8 Mapping the Model to the Metal Cloud Model Find the Gaps! Security Control Model Applications SDLC, Binary Analysis, Scanners, WebApp Firewalls, Transactional Sec.

16 To Build a Private Cloud Private Cloud Federation Virtualized Data Center Internal Cloud Virtualization Information Security Cloud Computing External Cloud

17 Benefits of the Private Cloud What are the benefits of a private cloud? Expand scalability Lower infrastructure Increase utilization Improve end-user productivity Improve reliability Increase security Gain access to more sophisticated applications Downsize the IT department Save energy

18 Limitations of the Private Cloud Limitations of Existing Cloud Computing Solutions A lack of interoperability Application Compatibility Difficulty in meeting compliance regulations Inadequate security
