Cloud: Dawn of a New Age• Cloud – overhyped in the short run,
underestimated in the long term• Compute becoming a utility• Changes everything: business models, venture
capital, R&D, ……

What is Cloud Computing?• Compute as a utility: third major era of computing• Cloud enabled by
• Moore’s Law• Hyperconnectivity• SOA• Provider scale
• Key characteristics• Elastic & on-demand• Multi-tenancy• Metered service

2011-2014: the Hybrid Enterprise
enterprise boundary
public clouds
Extended Virtual Data Center
private clouds
cloud of users
Notional organizational
boundary
• Dispersal of applications• Dispersal of data• Dispersal of users• Dispersal of endpoint
devices

Cloud Forcing Key Issues• Critical mass of separation between data owners
and data processors• Anonymity of geography of data centers &
devices• Anonymity of provider• Transient provider relationships• Physical controls must be replaced by virtual
controls• Identity management has a key role to play• Cloud WILL drive change in the security status
quo• Reset button for security ecosystem

Key Cloud Security Problems of Today
From CSA Top Threats Research:• Trust: Lack of Provider transparency, impacts
Governance, Risk Management, Compliance • Data: Leakage, Loss or Storage in unfriendly geography• Insecure Cloud software• Malicious use of Cloud services• Account/Service Hijacking• Malicious Insiders• Cloud-specific attacks

Key Problems of Tomorrow
•Globally incompatible legislation and policy
•Non-standard Private & Public clouds•Lack of continuous Risk Mgt & Compliance monitoring
•Incomplete Identity Mgt implementations
•Haphazard response to security incidents

Sample Guidance - Governance• Best opportunity to secure cloud engagement
is before procurement – contracts, SLAs, architecture
• Know provider’s third parties, BCM/DR, financial viability, employee vetting
• Identify data location when possible• Plan for provider termination & return of assets• Preserve right to audit where possible• Reinvest provider cost savings into due
diligence
![Page 12: Cloud Security Challenges Today and Tomorrow](https://reader036.vdocuments.net/reader036/viewer/2022062302/56816975550346895de15a5a/html5/thumbnails/12.jpg)

Sample Guidance - Operating• Encrypt data when possible, segregate key
mgt from cloud provider• Adapt secure software development lifecycle• Understand provider’s patching, provisioning,
protection• Logging, data exfiltration, granular customer
segregation• Hardened VM images• Assess provider IdM integration, e.g. SAML,
OpenID

Cloud Controls Matrix Tool• Controls derived from
guidance• Rated as applicable to
S-P-I• Customer vs Provider
role• Mapped to ISO 27001,
COBIT, PCI, HIPAA• Help bridge the “cloud
gap” for IT & IT auditors
![Page 14: Cloud Security Challenges Today and Tomorrow](https://reader036.vdocuments.net/reader036/viewer/2022062302/56816975550346895de15a5a/html5/thumbnails/14.jpg)

Consensus Assessment Initiative• Research tools and processes to perform
shared assessments of cloud providers• Lightweight “common criteria” concept• Integrated with Controls Matrix• Ver 1 CAI Questionnaire released Oct
2010, approx 140 provider questions to identify presence of security controls or practices – use to assess cloud providers today
![Page 15: Cloud Security Challenges Today and Tomorrow](https://reader036.vdocuments.net/reader036/viewer/2022062302/56816975550346895de15a5a/html5/thumbnails/15.jpg)

CloudAudit• Open standard and API to automate
provider audit assertions• Change audit from data gathering to data
analysis • Necessary to provide audit & assurance at
the scale demanded by cloud providers• Uses Cloud Controls Matrix as controls
namespace • Use to instrument cloud for continuous
controls monitoring

The need for the Security as a Service Initiative• Information assurance challenged by disruptive
trends (cloud, mobility, social networking, etc)• Cloud provides opportunity to rethink security
(economics, architecture, service delivery models, etc)
• Fulfill 2nd half of mission statement:“To promote the use of best practices for providing
security assurance within Cloud Computing, and provide education on the uses of Cloud
Computing to help secure all other forms of computing.”
