1 Secure Cloud Computing

2 Agenda Current Security Threat Landscape Over View: Cloud Security Overall Objective of Cloud Security Cloud Security Challenges/Concerns Cloud Security Requirements Strategy for Securing Cloud Infrastructure & Services Approach & Methodology for Securing Cloud Infrastructure & Services Government laws regarding data security and controls Q&A

3 Advanced Targeted Attack Life Cycle Criminal Theft Espionage Sabotage After the Fact Expensive Public Uncertainty COMPROMISE CONTAINMENT ATTACK DISCOVERY High Value Data Key Systems Exploit Weakness Stealthy Replacement Process Preparation Sadder but Wiser 2

4 Security-Related TCO Is Skyrocketing Multiple products operate in separate functional silos Constantly rising costs of operational security No efficiency, no effectiveness Stale defenses lack adaptive, contextaware capabilities Increasingly complex to manage 4

5 Recent Notable Advanced Targeted Attacks Targeted attacks against Point-of-Sale (POS) systems Memory parsing/scraping malware Extracts full magnetic stripe data out of memory Not detected by traditional A/V Not detected for a significant amount of time Substantial damage million credit cards where ex-filtrated in the TARGET compromise Containment took long (VISA) 5

6 Evolution of Cloud Computing

7 Evolution of the Datacenter Discrete Datacenter Compute Management Storage Network Consolidation Discrete Networks Traditional Security - Policies tied to physical attributes Virtualized Datacenter Servers Unified Network VM VM VM VM Mgmt Storage Arrays Flexible Management 10G Unified Network Virtualized Security - Context aware policies Cloud Datacenter Cloud Infrastructure Security Network Storage Compute Datacenter Facilities (e.g. cooling, power) Efficient and Secure Open Architecture Simplified Network Federated Security - Security delivered as a set of services

8 Cloud Enabler-Virtualization Virtualization = New platform for greater flexibility Flexibility & Scalability Rapid deployment of Servers & Desktops based on standard built Heterogeneous OS & Application environment running on one single HW Virtualization changes the definition of an endpoint Virtualized systems are no longer systems, they become data Virtual images built on the fly re-define the notion of an asset

9 The Business Need for a New Model Reduce Costs, Improve Agility 5 weeks Workload Some minutes = Differentiated storage Differentiated networks Differentiated isolation Differentiated security Other 3 rd party services Few Days 9

10 Reduce Costs, Improve Agility for all Datacenter Security and Services Differentiated storage Differentiated networks Minutes VDC Differentiated isolation Differentiated security Few Days Other 3 rd party services Datacenter Security Consolidated Workload-centric Policy-driven Extensible

11 Virtual Datacenter Cloud Infrastructure Datacenter spans physical, virtual and cloud deployments SaaS Applications Manage Dashboard PaaS Workloads Data Policies Workflows Compliance Infrastructure IaaS Compute Storage Network Essential Characteristics Broad Access, Rapid Elasticity, On Demand Self Service, Resource Pooling

12 Overall Objective of Cloud Security: Transparency Secure cloud infrastructure- Physical & Virtual Delivering Secure Cloud Services Providers should implement current & future cloud Standards & Certifications Automation of auditing & security 12 Transparency Confidence

13 Cloud Security Challenges/Concerns Data and Identity Centric Controls in Cloud are hard Dynamic perimeter based on data access and service requirements vs. logical network separation How do provision (and de-provision) identify + authorization across a network of providers Data Leakage threats from Cloud Infrastructure Database Compromises from Cloud Infrastructure High Availability and Performance requirements Virtual infrastructure makes traditional security solutions difficult on both network Content security Lack of Visibility in Inter-VM traffic Advanced Persistent Threats (e.g. Stuxnet, Operation Aurora, Operation Shady RAT etc.) Security controls need to understand the legacy and next generation message exchange protocols Anti-malware protection across large volumes of data must be optimized Protect access to critical data resources from multiple threat vectors to include insiders

14 Cloud Security Requirements Dynamic Risk Assessment Enterprise framework that support Machine to Machine data collection for continuous monitoring Comprehensive assessment for vulnerability, behavior, configuration and impact Real-time discovery capability for assets, applications and data Threat-Based Defense Defend the key attack vectors and priority targets based on intelligence Automated assessments with countermeasure awareness No impact to availability or performance of critical systems Handling APT Attacks Monitoring across several domains Integration of IT risk data or events with cyber physical data for impact decisions & higher level decision support systems Handling Big Security Data

15 Strategy for Secure Cloud Infrastructure & Services

16 Cloud Security Approach/Methodology Secure the Physical and Virtual Datacenter Architecture Defend the whole of the datacenter from infrastructure to application and across all threat vectors Enable comprehensive readiness assessment for web applications, databases and systems Provide continuous monitoring, rapid data retrieval and analysis for incident response Application access through API Calls Secure the Cloud Provider Protect data and identity services in the provider datacenter Secure Software-as-a-Service providers with Cloud Security Platform Enable Secure Use of Cloud Services Understand messaging protocols to ease integration of legacy systems and provide data loss protection Identity management provided by Cloud Based Identity Management solution
