In early 2010 I facilitated a Cloud Computing Risk Assessment for presentation at ISACA Victoria Chapter based on my own 22 years of experience on as both a customer and as a service provider. Over the course of the last 7 years I have been working almost exclusively with Cloud Computing Vendors, Suppliers, Cloud Computing Service Providers to adopt ISO 27001 – Information Security Management System (ISMS). The adoption of ISO 27001 ISMS has been very badly communicated because it is so new and so many consultants are jumping on the band wagon I felt that this would be useful. In 2010 I had no idea that ISO 27001 would become the De Facto security standard for Cloud Computing that it has. Since that time I have added additional slide share presentation to review what a typical statement of work would look like and the Human Resource Allocation might look like in attempts to raise awareness and knowledge of this rapidly growing profession. If you have any questions or require some of my expertise please contact me at mark.bernard@techsecure.ca or 250-812-7060. These day I have been traveling around the globe helping corporations and I know that I can help you too.

    • CICA is a new approach to message design aimed at resolving the costlyproliferation of differing (and often incompatible) XML messages used forbusiness-to-business data exchange. CICA gives developers access to reusablecomponents that can be used to construct interface standards to satisfy commonbusiness requirements as well as industry-specific needs.CICA is a syntax-neutral architecture that supports both business content andimplementation information. CICA messages ("documents") can currently beexpressed as XML schemata.

    • •Quality of Service standards?•Service Level Agreement?•Eliminating capital expenditures on hardware and software.•Transferring for Service Management to the Service Provider.•Access to broader ranges of applications at lower costs?•More functionality though their service offerings?•More flexibility with capital budget vs operating budget?•Improve the efficiency of their data center by transferring inefficient processes.•Who will champion the adoption of Cloud Computing?•Open standards that fuelled the rapid growth of Cloud Computing?
    • • Clouds are complex comprising highly specialized applications made up of even more granular, yet simple application procedures replicated thousands of times• Clouds can generate both security benefits and risks• How can we establish and maintain trust?• How can the virtualization of servers, and systems maintain acceptable levels of security?• How can encryption be successfully deployed and managed over extremely complex over millions and maybe billions of unique data streams and business channels?• How can we even hope to achieve mandatory compliance with statutes, regulations and contractual obligations?
    • •Tactically “Virtualization” is about saving money •Strategic “Virtualization” leads to flexible resourcing1). Enables economies of scale: Cloud providers maximize the usage of their resources to make money.2). Decouples users from implementation: Virtualization forces the relationship to change fromimplementation, to service level agreements.3). Speed, flexibility, agility: Early adopters of cloud computing talk about how quickly they can get newservers online. Compared to the 4-6 weeks it takes an average IT shop to deploy a server, just aboutanything is faster. However, virtual machines can be deployed roughly 30 times faster.4). Breaks software pricing and licensing: Software Manufacturers can’t charge users for physicalcapacity when only a small portion of that is used. Its also impossible to charge for every potential serverthe software might be running on.5). Enables, motivates chargeback: When servers can be delivered in minutes rather than weeks, IT usersask for more – roughly two times as much. IT needs to focus more on usage accounting, and chargeback.
    • The term "Web 2.0" (2004–present) is commonly associated with web applicationsthat facilitate interactive information sharing, interoperability, user-centered designand collaboration on the World Wide Web. Examples of Web 2.0 include web-based communities, hosted services, web applications, social-networking sites,video-sharing sites, wikis, blogs, mashups and folksonomies.A Web 2.0 site allows its users to interact with other users or to change websitecontent, in contrast to non-interactive websites where users are limited to thepassive viewing of information that is provided to them.
    • •Authority Attack (with or without artefact): using fake identification or badge, utility service, or law enforcementuniform, to gain access or identify a key individual by name/title as supposed friend or acquaintance or claimingauthority such as a lawyer or auditor and demanding information (impersonation).•Zero-Sum Knowledge Attack: Baiting someone to add, deny or clarify pieces of information or incorrectinformation, claiming to know more than they actual do, to solicit more information.•Persistent Attack: Continuous harassment using guilt, intimidation and other negative ways to reveal information.This could take place over days, weeks, months.•Stake-Out Attack: Analyze operational activity over a period of time including people, regular mail, or specialcourier, and/or supply deliveries, the patrol patterns of guards, location of CCTV, off hours activity.•“The boy who cried wolf” Attack: Setting off a series of false alarms, either physical or digital, until some getstied of responding and disables the alarm system.•Help Desk Attack: Impersonating a current or new end-use needing help with access to a network or server.•Fake Survey/Questionnaire Attack: Win a free trip to Hawaii, or somewhere special in exchangefor completing a survey and answering questions about work or you network.

    • SCOPE: Review and assess proposed Cloud services for Software as a Service, Platform as aService and Infrastructure as a Service.RATIONALE: Consideration was given for the fact that Cloud services are a new servicedeliver approach that has not been fully implemented. More emphasis on patterning with serviceproviders and dependency on managing necessary controls through collaborative partnershipsand/or transferring risk completely to the service providers. Transparency of processes,consistency of outcomes, and quality of service and deliverables will become more and moreimportant and thus understanding of the potential issues important to its success.The threat-risk assessment was facilitated against existing best practices for information securitymanagement systems, ISO/IEC 27001:2005. These controls are based on industry best practicefor information handling based on known vulnerabilities and risks associated with mostbusinesses, however this standard was initially developed by and for government in the UK.

    • Security Posture:•Equilibrium State (EQ): In this state the threats are identified and the appropriate safeguards are deemed to be in place .•Vulnerable State (VU): In this state the threats far outweigh the safeguards.•Excessive State (EX): In this state the safeguards far outweigh the threats. This can result in an overspending in the area of securitymeasures.Information Classification:•Low Sensitivity (L): a). limited financial losses, b). limited impact in service level, or, c). performance, embarrassment andinconvenience.•Medium Sensitivity (M): a). loss of competitive advantage, b). loss of confidence in the government program, c). significant financialloss, d). legal action, or, e). damage to partnerships, relationships and reputations.•High Sensitivity (H): a). extremely significant financial loss, b). loss of life or public safety, c). loss of confidence in the government, d).social hardship, or, e). major political or economic impact.•Unclassified (U): a) information of public knowledge that can be found on most government web sites and would include suchinformation as the government telephone books, advertisements for job opportunities in the various ministries, government-wideinitiatives such as Government-On-Line, public health information, job classification level and range of pay scale.
