1 Security Considerations for Cloud Deployment Jeff Uehling, IBM i Network & Security Development [email protected] IBM - Rochester, MN

2 What is Cloud Computing? Is Cloud Computing really a new concept?

3 What is Cloud Computing? An IT consumption and delivery model Cloud computing is a consumption and delivery model inspired by consumer Internet service and is optimized for IT / Business Services Cloud enables: User self-service Outsourcing options Dynamic scalability Multiple types of clouds will coexist: Private Deployed Inside a customer s firewall Public Provided and managed by a 3 rd party via subscription Hybrid a mix of Public and Private models based on Workload An effective cloud deployment is built on a dynamic Infrastructure and should be part of an overall Data Center transformation plan

4 Clouds enable a broad spectrum of deployment options IBM Corporation IBM Corporation

5 Cloud Differentiators There are Many! Time to Deploy a Server Weeks or Months Seconds to Minutes Commitment to use Service Negotiate & Commit Year-long Contract Select from Catalog & Pay As You Go Necessary Upfront Investment $ $K-$M in Infrastructure $$ per IT hour No or Low Upfront per IT hour

6 IT Benefits from Cloud Computing are Real Results from IBM cloud computing engagements Increasing speed and flexibility Test provisioning Weeks Minutes Change management Months Days/hours Release management Weeks Minutes Service access Administered Self-service Standardization Complex Reuse/share Metering/billing Fixed cost Variable cost Reducing costs Server/storage utilization 10 20% 70 90% Payback period Years Months Source: Based on IBM and client experience.

8 Cloud: because the majority of IT cost is in people, Cloud Computing is becoming popular at the higher layers People Services MBPS (ehr, LBPS, etc.) Live Mesh Service Cloud Layers Business Services Application Services Platform Services ISSC/SO BCRS Live ISS Infrastructure Services Static, dedicated, outsourced Network-delivered, off-premises Shared, automated, dynamic

9 What Cloud Services are available today? Hundreds Thousands growing by the day!

10 Market Examples Cloud Delivery Examples IBM Examples Collaboration CRM/ERP/HR Business Processes Industry Applications Software-as-a-Service Middleware Web 2.0 Application Runtime Java Runtime Database Development Tooling Platform-as-a-Service Developer Cloud Data Center Servers Networking Storage Fabric Shared virtualized, dynamic provisioning Infrastructure-as-a-Service Computing on Demand

11 Top public workloads Audio/video/Web conferencing Service help desk Infrastructure for training and demonstration WAN capacity and VoIP infrastructure Desktop Test environment infrastructure Storage Data center network capacity Server Infrastructure and collaboration workloads emerge as most appropriate for a Public offering Top private workloads Data mining, text mining, or other analytics Data warehouses or data marts Business continuity and disaster recovery Test environment infrastructure Long-term data archiving/preservation Transactional databases Industry-specific applications ERP applications Database, application and infrastructure workloads emerge as most appropriate for a Private offering

12 Cloud Usage Models 1. End User to Cloud - Application running on the cloud with access for end-users 2. Enterprise to Cloud to End-user (Interoperability) - Applications running in the public cloud access from employees and customers 3. Enterprise to Cloud (Integration) - Cloud application integrated with internal IT capabilities 4. Enterprise to Cloud to Enterprise (Interoperability) - Cloud application running in the public cloud and interoperates with partner applications (supply chain) 5. Enterprise to Cloud (Portability) - Cloud application running in the cloud flexibility to move to a different cloud provider in the future or in-house 6. Private (intra) Clouds - Interoperability / integration within elements of a private cloud and between a private cloud and a traditional environment

13 Model 1: End User to Cloud What is it? Application running in the cloud with access for end-users Scenarios : Get new Web app provisioned worldwide quickly (e.g., the next facebook, linkedin, gmail, etc ) Don t need IT infrastructure, flexible acquisition Public Cloud Application

14 Model 2: Enterprise to Cloud to End-user What is it: Deploy cloud based application specifically for the cloud access for employees and for customers Scenarios: Online sales through catalog, needs to link back into enterprise systems for fulfillment web app and shopping cart in cloud, fulfillment inside existing enterprise systems Two sub-models End User is employee in the Enterprise (e.g., Travel Expense Account application) End User is Web customer outside the Enterprise (e.g., online sales) Public Cloud Application External Internal Enterprise IT (Traditional, Private Cloud or Hybrid)

15 Model 3: Enterprise to Cloud (Integration) What is it? Cloud application integrated with internal IT capabilities Scenarios : Typical approach of integrate with existing on premises and offpremises capabilities or other cloud application (customer list, access control, data) Integrate with existing on premise capabilities Public Cloud B Application / Data External Internal Enterprise IT (Traditional, Private Cloud or Hybrid)

16 Model 4: Enterprise to Cloud to Enterprise What is it? Cloud application running in the public cloud interoperate with partner applications (supply chain) Scenarios : Brokers, common function providers (e.g., supply chain, broadcast recall to multiple customers, broadcast RFP to suppliers, classic B2B) Large manufacturer A Public Cloud Application External Internal Large manufacturer B

17 Model 5: Enterprise to Cloud (Portability) What is it? Cloud application and/or data running in the cloud flexibility to move to a different cloud provider in the future or in-house Scenarios: Flexibility and choice to change application platform suppliers Write once, run anywhere Public Cloud A Application / Data Move to another cloud Public Cloud B Application / Data External Move inhouse Internal Application / Data Enterprise IT (Traditional, Private Cloud or Hybrid)

18 IBM Power Systems Model 6: Private (intranet) Cloud What is it? A private cloud-based service, offers many of the benefits of a public cloud computing environment. The difference is that data and processes are managed within the organization. Scenarios: The enterprise would leverage a private cloud to provide Self-service capabilities, real-time infrastructure. Interoperability / integration within elements of a private cloud and between a private cloud and a traditional environment On-Premise or Off Premise Private Cloud OS Images (Virtual / Physical) External Internal Database Schema /Instances Storage (SAN/NAS)

19 If this is so logical Why isn t everyone doing it?

20 So what type of business and security challenges does cloud computing introduce? Today s Data Center Tomorrow s Public Cloud We Have Control It s located at X. It s stored in server s Y, Z. We have backups in place. Our admins control access. Our uptime is sufficient. The auditors are happy. Our security team is engaged. Who Has Control? Where is it located? Where is it stored? Who backs it up? Who has access? How resilient is it? How do auditors observe? How does our security team engage?

21 Security is a top concern with cloud computing The Tale of two studies shows that Security is the number one inhibitor to customers adopting cloud technologies. What, if anything, do you perceive as actual or potential barriers to acquiring public cloud services? Security/privacy of company data 69% Service quality Doubts about true cost savings Performance / Insufficient responsiveness over network Difficulty integrating with in-house IT 54% 53% 52% 47% Source: IBM Market Insights, Cloud Computing Research Source: Oliver Wyman Interviews

22 Gartner s security risks of cloud computing Privileged User Access Data Segregation Data Recovery Investigative Support Regulatory Compliance Data Location Disaster Recovery Gartner: Assessing the Security Risks of Cloud Computing, June 2008

23 Risks introduced by cloud computing Restrictions imposed by industry regulations over the use of clouds for some application Challenges with an increase in potential unauthorized exposure when migrating workloads to a shared network and compute infrastructure Data Security Over where the information is located and stored, who has access and backups, how is it monitored & managed including resiliency Less Control Control needed to manage firewall and security settings for applications and runtime environments in the cloud Security Management Concerns with high availability and loss of service should outages occur Compliance Reliability

24 Top 10 factors for a secure Cloud Infrastructure Data Protection Access and Identity Application Provisioning & Deprovisioning Application & Environment Testing Service Level Agreement Vulnerability Management Business Resiliency Audit & Governance Cross Border Protection Intellectual Property & Export Laws

25 What are the Risks Policy and Organizational Risk - Things that may directly degrade the ability of the consumer organization to conduct business in efficient manner Legal Risk - Things that may put the consumer organization in breach of the law or that may prevent compliance with specific legal mandates Technical Risk - Things that may disrupt normal operations of the consumer organization or cause loss of value over intangible assets (data, reputation, etc.) Transitional Risk - Things that may temporarily put the consumer organization s traditional infrastructure and operations under increased risk

26 Policy and Organizational Risk 5 INTRINSIC RISKs 1. Resource sharing and pooling - Data (intangible assets) can not be tied to physical assets (tangible HW resources), assets must be referenced by their content not their supporting media or storage location 2. Network accesses - Porous perimeter, authorization & authentication become more important issues 3. Service elasticity and scalability - Grow-on-demand and pay-as-you-go can backfire. Seemingly infinite capacity may not be so under attack. 4. On-demand self-service - Hijacking of the consumer s control plane (user interface. 5. Measured service - Economic denial of service, depletion of service quota

27 Legal Risks E-discovery and Subpoena - Where is the evidence that I need to hand out? Intangible assets cannot be mapped to physical assets or geographical locations. Service provider may not be cooperative. Resources are pooled and shared so they can t be taken without affecting co-tenants and/or service provider operations. Change of jurisdiction - Which privacy (Data protection ) and security laws are applicable when intangible assets and processes are outsourced to service providers with distributed data centers across several continents? Do national laws local to the service provider s data center supersede those local to consumer s organization? Data protection - It can be difficult for the cloud customer (in its role of data controller) to effectively check the data processing that the cloud provider carries out, and thus be sure that the data is handled in a lawful way. Conflicting data encryption standard requirements, lack of notification of data breaches by the service provider, storage of data collected unlawfully by co-tenants.

28 Technical Risks Isolation failure - Break out of the VM, storage compartment, virtual network, VPN, etc. Compromise of the management interface - Hijack of the consumer organization s cloud computing infrastructure, loss of control plane (user interface). Data leakage Data Leakage to co-tenants (Intra-cloud ) or from the cloud Insecure data lifecycle management - Insecure or ineffective deletion of data, loss of consistency, data duplication Economic denial of service - Depletion of quota vs. runaway service costs vs loss of efficiency Coarse access control - Insufficient granularity to implement authentication, authorization or auditing controls Conflicting Provider- Consumer security standards - Provider can t meet the consumer organization s security requirements

29 Transitional Risks Disruption of endpoint security - Cloud applications that require installation of client-side components or use of specific desktop applications may weaken the consumer s security posture Credential Leakage - Improper lifecycle management of credentials needed to access cloud applications. Shared access for testing purposes, open access to cloud user interface Punctured perimeter - Punching temporary holes in network filtering rules. Network IDS with lost visibility, tunneling. Transitive trust - Internal/ legacy applications suddenly made to transitively trust the cloud. Reuse of credentials, hard-coded passwords, certificates, etc.

30 Security complexities raised by virtualization New complexities: Dynamic relocation of VMs Increased infrastructure layers to manage and protect Multiple operating systems and applications per server Elimination of physical boundaries between systems Manually tracking software and configurations of VMs Risk depends on cloud type Public cloud riskiest (mixed tenants) Private cloud least risky (BAU) but places higher demands on the company Hybrid (private + public) provides a balanced solution sensitive data stays private public cloud used for non-sensitive data. Can be always or just for demand spikes 1:1 ratio of OSs and applications per server 1:Many ratio of OSs and applications per server Additional layer to manage and secure

31 Different cloud workloads have different risk profiles One-size does not fit-all High Mission-critical workloads, personal information Tomorrow s high value / high risk workloads need: Need for Security Assurance Analysis & simulation with public data Quality of protection adapted to risk Direct visibility and control Significant level of assurance Today s clouds are primarily here: Low Training, testing with non-sensitive data Low-risk Mid-risk High-risk Business Risk Lower risk workloads One-size-fits-all approach to data protection No significant assurance Price is key
