Security – Grand Challenge for the Adoption of Cloud Computing

Security and Cloud Computing

What is Cloud Security?

Confidentiality, integrity, availability

of mission-critical IT assets

Stored or processed on a cloud computing platform

Cloud Computing

Software as a Service

Utility Computing

Grid Computing

There is nothing new under the sun

but there are lots of old things we don't know.

Ambrose Bierce, The Devil's Dictionary

where is the data moving from private to public leads to a real or perceived loss of control
Security and Cloud Computing



Of respondents are concerned with cloud interfering with their ability to comply with regulations

Of enterprises consider security #1 inhibitor to cloud adoptions

Of enterprises are concerned about the reliability of clouds


Where is the Data? – Moving from Private to PublicLeads to a Real or Perceived Loss of Control

We Have Control

  • It’s located at X.
  • We have backups.
  • Our admins control access.
  • Our uptime is sufficient.
  • The auditors are happy.
  • Our security team is engaged.

Who Has Control?

  • Where is it located?
  • Who backs it up?
  • Who has access?
  • How resilient is it?
  • How do auditors observe?
  • How does our security team engage?

Security and Cloud Computing

One-size does not fit-all:

Different cloud workloads have different risk profiles


Mission-critical workloads, personal information

Tomorrow’s high value / high risk workloads need:

  • Quality of protection adapted to risk
  • Direct visibility and control
  • Significant level of assurance

Analysis & simulation with public data

Need for Security Assurance

Today’s clouds are primarily here:

  • Lower risk workloads
  • One-size-fits-all approach to data protection
  • No significant assurance
  • Price is key

Training, testing with non-sensitive data

Security and Cloud Computing

Cloud Security = SOA Security + Secure Virtualized Runtime

  • Service-oriented Architecture
  • SOA Security model and protocols apply
  • Technical challenges: multi-tenancy, across trust domain, REST-based, new protocols (e.g., OpenID)
  • Definitional challenges: profiles and security SLAs for cloud

Virtualized Runtime

Top Threats and Risks in Cloud Computing

  • Process/VM Isolation, data segregation, multi-tenancy
  • Malicious insiders (co-tenants, cloud provider)
  • Management (incl. self-service) interface compromise
  • Insecure interfaces and APIs
  • Uncertainty over data location
  • Data protection and security
  • Data recovery, resiliency
  • Insecure or incomplete data deletion
  • Account or service hijacking
  • Abuse of cloud services (extrusion)
  • Compliance risks

Example for SOA-style Security applied to Cloud:IBM Tivoli Federated Identity Manager

SAML 1.0 / 1.1 / 2.0


Liberty ID-FF 1.1/ 1.2

Information Card Profile 1.0


Centralized user access management to on- and off-premise apps and services

Tools for user enrollment, WS-Trust based security token services, web access management

TFIM = Tivoli Federated Identity Manager

TFIM BG = TFIM Business Gateway for SMB deployment

TSPM = Tivoli Security Policy Manager for data entitlement management

Security and Cloud ComputingExample for Securing the Virtualized Runtime:IBM Security Virtual Server Protection for VMware vSphere 4
  • VMsafe Integration
  • Firewall and Intrusion Prevention
  • Rootkit Detection / Prevention
  • Inter-VM Traffic Analysis
  • Automated Protection for Mobile VMs (VMotion)
  • Virtual Network Segment Protection
  • Virtual Network-Level Protection
  • Virtual Infrastructure Auditing (Privileged User)
  • Virtual Network Access Control

This is an example where virtualization enables an approach to security that would not be possible in a non-virtualized infrastructure!
