2. Cloud Computing Storage Security …….?
Cloud describes the use of a collection of “SECURED”
services, applications, information, and infrastructure
comprised of pools of compute, network, information and
storage resources.
Cloud Security is security principles applied to
protect data, applications and infrastructure
associated within the Cloud Computing technology.

3. COMPANIES ARE STILL AFRAID TO USE CLOUDS

4. INTEGRITY
LACK OF TRUST IN THE CLOUD
LOSS OF CONTROL IN THE
CLOUD
MULTI-TENANCY ISSUES IN THE
CLOUD
Tenants share a pool of resources and have
opposing goals

5. •Encrypt data in transit, at rest, backup media
• Secure key store
•Protect encryption keys
•Ensure encryption is based on industry/govt
standards.
•NO proprietary standard
•Limit access to key stores
•Key backup & recoverability
•Test these procedures

6. Research for Storage Security:
1.Authorization:
2.Encryption:
3. Segmentation:
• Multi-level authorization
• The Face Fuzzy Vault
• RSA Encryption
• AES Encryption
• Hybrid Encryption
• Metadata Based Storage Model
• Multi-cloud Architecture Model

7. ESSENTIAL
CHARACTERISTICS
On-demand service
Get computing capabilities as
needed automatically
Broad Network Access
Services available over the net
using desktop, laptop, PDA,
mobile phone

8. ESSENTIAL
CHARACTERISTICS
 Resource pooling
 Provider resources pooled to
server multiple clients
 Rapid Elasticity
 Ability to quickly scale in/out
service
 Measured service
 control, optimize services based
on metering

9. CLOUD SERVICE MODELS
 Software as a Service (SaaS)
 We use the provider apps
 User doesn’t manage or control
the network, servers, OS, storage
or applications
 Platform as a Service (PaaS)
 User deploys their apps on the
cloud
 Controls their apps
 User doesn’t manage servers, IS,
storage

10. Infrastructure as a Service (IaaS)
Consumers gets access to the
infrastructure to deploy their stuff
Doesn’t manage or control the
infrastructure
Does manage or control the OS,
storage, apps, selected network
components

11. Cloud Computing
Advantages:
•Security
•Privacy
Disadvantages:
• Backup and Recovery
• Almost Unlimited Storage
• Efficiency and Performance Increasing
