1. Exploring the real definition of Cloud The most sensible Definition of Cloud:“Forget your technical definition of the Cloud, askyour mom what the Cloud is….…And what your mother will tell you about the Cloudis that it means it’s not on my computer.”Dave Asprey – Global VP, Cloud Security, Trend Micro‘Navigating through the Cloud ‘ - Podcast Episode 23 rd May 2012

2. Scope of this presentation • Mission critical, non-commodity, enterprise systems • Multi-year investment in a cloud solution • Shifting existing enterprise capability to Cloud, (or integrating) • Mid to large enterprise • High security, privacy and confidentiality needs • High governance loads and compliance environments • Low risk appetite / high failure penalty environments
3. Systemic vs. Technical RiskSystemic Risks• Taking a systemic view of risk will give you a better perspective of the actual risk, rather that what you think the risk might be• Systemic risks are those with the greatest potential impact as they affect the entire system (ie: Organisation, government, country, world…) • Case in Point: How is that the finance industry, which is one of the more regulated, and invests heavily in risk identification, mitigation and transference could be the cause of the current global financial problems?• Systemic risk for the enterprise is the silent killer and is often the hardest to identify as only a few have a complete, transparent and objective overview of the overall enterprise in sufficient detail.• Mitigation through approaches such as Enterprise Risk Management (ERM), origins in fraud, organisational governance, insurance, etc
3. Systemic vs. Technical Risk Technical (or functional) Risk • Identifying, categorising and ranking technical and functional risks is core to conventional IT risk assessment approaches: o Risk of a specific event = (Impact x Probability of that event occurring) + Risk Adjustment • Underpins conventional risk certification frameworks e.g. ISO 2700X • Certification does not necessarily equal security or effectiveness of your risk management model • Often focusing on the diverse range of technical risks, does not account for the interaction between risks. • Systemic risks are often more significant than the sum of the individual, technical risks
4. Hybrid Cloud is the reality Hybrid will be the dominant form in the enterprise “Within five years, it will be primarily deployed by enterprises working in a hybrid mode”. - Gartner Gartner "Predicts 2012: Cloud Computing Is Becoming a Reality” (Published: 8 December 2011 ID:G00226103)
4. Hybrid Cloud is the reality …. And with the Hybrid Cloud comes complexity….

4. Hybrid Cloud is the reality…… …. As is the potential for complexity….! • Orchestrating versioning, change control and rollback • Life expectancy alignments • Business Continuity • Identity Management • Due diligence • Forensics • BYOD • Mobility • Legislative / Jurisdictional • Contractual complexity ….. To name but a few

4. Hybrid Cloud is the reality…… "Cloud consumers should budget for additional integration costs which can range from 10% to 30% — and sometimes as high as 50% — of the total cost of cloud IT projects.“ Gartner Predicts 2012: Cloud Services Brokerage Will Bring New Benefits and Planning Challenges - Published: 22 November 2011 G00227370
4. Hybrid Cloud is the reality…… Review, define and assign key roles in your Cloud environment. – Define your Cloud Computing Reference Architecture (CCRA) by reviewing applicability against published models (Eg NIST, IBM, etc) – Ensure you do not miss important roles (Eg: IBM CCRA does not include Cloud Broker, Cloud Auditor yet included in NIST CCRA)
4. Hybrid Cloud is the reality…… The emergence of the ‘Cloud Broker’
4. Hybrid Cloud is the reality…… IT Department in the Cloud?

4. Hybrid Cloud is the reality Hybrid cloud can contribute to…. •Increased vulnerability due to its fragmented architecture and larger surface … •however if it is properly architected, risks largely eliminated by implementing measures such as… o Deploying effective policy based key management processes o Properly segmenting your public and private clouds o Encrypting each part of the hybrid Cloud with separate keys o … amongst other measures
5. Adding in Mobility Mobile Devices •Are powerful cloud access devices •Extend the perimeter of your cloud •Disperse the perimeter to your cloud Have the potential to increase the vulnerability •The compromising of one of these mobile devices could be significant and compromise your entire cloud. •Use policy based key management regimes for your data.
6. BYOD or Bring Your Own Disaster? BYOD stands for Bring Your Own Device, •Reflects the increasing demands of users and organisations of their own IT departments to be increasingly agile and responsive to their needs when it comes to iPads, tablets and other mobile devices. •Read the NIST Draft Guidelines http://csrc.nist.gov/publications/drafts/800- 124r1/draft_sp800-124-rev1.pdf
6. BYOD or Bring Your Own Disaster? BYOD requires management: •Deploy Mobile Device Management systems (Remote wipe, policy enforcement) •Introduce a non-porous Virtual Desktop environment - No data can flow between the Cloud system and the mobile device itself •Containerisation: • Segregates corporate from personal data and applications • Enforces encryption and prevention of data leakage between containers • Application / device specific therefore can be a challenge to expand across the entire mobile environment for all applications.
7 . Hybrid Cloud + Mobility + BYOD Systemic Risk? Is the Systemic risk increased by the combination of: – Hybrid Cloud Y es ’ r is ‘ – Mobility we e a ns – BYOD? a t th t th ges d s ug o ul Iw
8. Standards? Which standards? Plethora of forums, industry groups and associations – Cloud Security Alliance – Cloud Standards Customer Council – Distributed Management Task Force (DMTF) – Cloud Management Working Group (CMWG) – The European Telecommunications Standards Institute (ETSI) – National Institute of Standards and Technology (NIST) – Open Grid Forum (OGF) – Object Management Group (OMG) – Open Cloud Consortium (OCC) – Organization for the Advancement of Structured Information Standards (OASIS) – Storage Networking Industry Association (SNIA) – The Open Group – Association for Retail Technology Standards (ARTS) – TM Forum’s Cloud Services Initiative Source: cloud-standards.org
8. Standards? Which standards?• Compliance standards were originally designed for on-premise IT systems and infrastructure that were relatively static• Auditing institutions are averse to cutting edge technologies• Is your organisation (or parts thereof) standards/compliance driven? – Compliance to Standards vs. Unimpeded Innovation based on principle of caveat emptor?• Regulators not providing much specific and concrete guidance on Cloud
9. Orchestrating the Transition#1: Adopt an integrated approach to enterprise Cloud• Standardised, traditional methodologies within specific disciplines such as IT security, project management, audit, and information security, in and of themselves, can be self limiting.• Each discipline and/or technology is only really effective when applied actively coordinated with the other key moving parts of the organisation Harmonization of functionally specific methodologies and technologies unleashes value and eliminates waste Cloud solutions may or may not help!
9. Orchestrating the Transition #2: Manage the conflicting messages • 24% of CEOs surveyed in the 2012 PWC CEO Survey expect ‘major change’. • The eighth annual KPMG 2012 Audit Institute Report identified “IT Risk and Emerging Technologies” as the second-highest concern for audit committees, which is unprecedented in the history of the report. • Cloud evangelists see cloud as imperative, others not • Rigorously test generic, enterprise Cloud policy statements in the context of your business unit, agency or department. Map and quantify the gaps Develop an effective mechanism for interpreting these messages in the context of your organisation
9. Orchestrating the Transition #3: Actively identify, embrace and managing shadow IT “Shadow IT can create risks of data loss, corruption or misuse, and risks of inefficient and disconnected processes and information” – Gartner* Embrace shadow IT, and define what and what is not eligible to be considered enterprise IT Develop, socialize and police appropriate policies on the selection of Cloud based services, no matter how innocuous for your key information assets. *CIO New Years Resolutions, 2012 ID:G00227785)
9. Orchestrating the Transition #4: Identify systemic risks across the organisation • Systemic risks can jeopardise all or major parts of the organisation Ensure your executives and key decision makers are aware of long term, systemic risks Understand the systemic risks inherent in long lead time IT projects where Cloud plays a critical part Consider implementing Enterprise Risk Management (ERM)
9. Orchestrating the Transition #5: Don’t gloss over complexity • Senior LOB managers with agency and/or functional responsibility over specific vertical silos of the organisation may underestimate the overall complexity of their own organisations as a whole. • From a functional perspective, specific methodologies and technologies exist to support specific activities, however integration can be the Achilles heel for single instance Cloud applications. • Cost your medium / long term Cloud strategy with rigour. Don’t believe that simple IT solutions can paper over underlying business complexity. Test assumptions if critical.
