3. Cloud Computing
Cloud computing means storing and accessing data and programs
over the Internet instead of your computer's hard drive. Everything
you need is physically close to you.
Meaning of Cloud – :
Common implies multi-tenancy, not
single or isolated tenancy
Location-independent
Online
Utility implies pay-for-use pricing
Demand implies
infinite,immediate,invisible
scalability

5. What is Cloud Security
 Cloud Security is security principle applied to protect
data, applications and infrastructure associated within the
cloud computing technology.
Why is Cloud Security Important?
 Increasing usages of cloud security in non-traditional
sectors.
 To protect confidential data of its customers
 Growing adoption of cloud security in government
departments.
 Growing usages of cloud services for critical data
storage.

6. Security issues associated with the cloud
 Cloud in a variety of different service models and
deployment models.
 Concerns associated with cloud computing.
Cloud Provider
• Person those provided cloud services
Customer’s
• Person who use cloud services

7. Cloud Security Challenges
 It is clear the security issue has played the most important role
in hindering cloud computing acceptance.
 Well known security issues such ass data loss,phishing,botnet
pose serious threat to organization’s data and software.
 Multi-tenancy model and the pooled computing resources in
cloud computing has introduced new security challenges that
requires novel techniques to tackle with.
 Insider threats.

8. Security Architecture

9. Techniques for cloud security
 Data Integrity
 Data Confidentiality
Homomorphic Encryption(RSA Algorithm’s)
Encrypted Search and Database(TSFS Algorithm’s)
Distributive Storage(Chunk’s & Shamir’s Algorithm’s)
Deletion Confirmation(FADE System)
Data Concealment(Watermarking Method)
Hybrid Technique(RSA Public key Algorithm)
 Data Availability
 Data Privacy(ORAM Algorithm)
