3. What is cloud computing?
Cloud Computing is a technology that uses the
internet and central remote servers to maintain data
and applications.
Simple applications of Cloud Computing is yahoo
email, Gmail or hotmail etc.

4. How cloud computing works?
Cloud computing consists of two layers, namely
BACK END
FRONT END

5. Two layers:
Front end - Is the part seen by the client,i.e. the
computer user. this includes the client’s network (or
computer) and the applications used to access the
cloud via user interface such as a web browser.
Back end – Is the ‘cloud’ itself, comprising various
computers, servers and data storage devices..

6. Types of clouds:

7. Public Clouds Computing environment are open for
used to anyone who wants to sign up and use them.
(Eg:Amazon Web services,google Apennine).
Private Cloud is a Cloud Computing infrastructure
created by an organization for its own internal use
rather than using someone else’s infrastructure.
(Eg:Amazon EC2)
Hybrid Cloud is a composition of at least one private
cloud and at least one public cloud.
(Eg.IBM)

8. Types of cloud
services:
SAAS END CUSTOMERS
PAAS DEVELOPERS
IAAS SYS ADMINS

9. What is IAAS?
Infrastructure as a service is provisional in which an
organization outsources the equipment used to support
operations, including storage,hardware,servers and
networking components
Characteristics and components of IAAS include:
o utility computing service and billing model.
o Automation of administrative tasks.
o Dynamic scaling.
o Desktop virualization.
o Policy-based services.
o Internet connectivity.

10. What is PAAS?
Platform as a service (PAAS) is the deliverance of a
computer platform and resolution stack as a service.
It regularly goes extra with the inclusion of a software
progress platform, that is designed for cloud computing at
the top of the cloud stack.
Characteristics of PAAS:
o PAAS includes workflow amenities for application
propositions.
o PAAS is app progress, testing use and hosting as well as
proposition services such as group partnership.
o PAAS is web service amalgamation,app
versioning,security,storage,persistence,scalability,state
administration and app instrumentation.

11. What is SAAS?
Applications or software is delivered as a service to the
customer who can access the program from any online
device who can access the program from any online device
,eliminating the need to install and run the applications
on the customer’s own computers and simplifying
maintenance and support.
Characteristics of SAAS:
o Multi tenant Infrastructure.
o Easy Customization.
o Better Access.

12. CLOUD
SECURITY:

13. Cloud Security Analysis:
Some key issues:
o Trust ,multi-tenancy,encryption,compliance.
Cloud Security is a tractable problem.
o There are both
ADVANTAGES
CHALLENGES

14. Security Advantage:
Shifting public data to a external clod reduces the exposure
of the internal sensitive data.
Cloud homogeneity makes security auditing/testing
simpler.
Clouds enable automated security management.
Redundancy/disaster recovery.

15. Some of the Security Challenges:
Trusting vendor’s security model.
Customer inability to respond to audit findings.
Obtaining support for investigations.
Proprietary implementations can’t be examined.
Loss of physical control.

16. Security Related Cloud services:
Cloud Provisioning Services.
Cloud Data Storage Services.
Cloud Processing Infrastructure.
Cloud Support Services.
Cloud Network and Premier Security.
Elastic Elements :Storage Processing.

17. Balancing Threat Exposure:
Private Clouds may have less threat exposure than
community clouds which have threat exposure than public
clouds.
Massive Public Clouds may be cost effective than large
community clouds which may be more effective than small
private clouds.

18. Putting it Together:
Most clouds will require very strong security controls.
All models of cloud may be used for differing tradeoffs
between threat exposure bad efficiency.
There is no one “cloud “.there are many models and
architectures.
Federated Risk Management of Cloud Systems.

19. Working Process of Fed RAMP:
Fed RAMP is the result of close collaboration with security
and cloud experts from the federal council and its working
as well as private industry.
Fed ramp will authorize cloud systems in a four step
process:
o INITIATING:
o ASSESSING:
o AUTHORIZING:
o LEVERAGING:

20. INITIATING: The Fed RAMP assessment process is initiated
by agencies or Cloud Service Provider (CSPs) beginning a
security authorization using the Fed RAMP requirements.
ASSESSING: CSPs must implement the Fed RAMP security
requirements on their environment and hire a Fed RAMP
approved third party assessment organization (3PAO) to
perform an independent assessment to audit the cloud system
and provide a security assessment package for review.
AUTHORIZING: The Fed RAMP Joint Authorization
Board(JAB) will review the security assessment package based on
a prioritized approach and may grant a provisional
authorization.
LEVERAGING: Federal agencies can leverage CSP
authorization packages for review when granting an agency
Authority To Operate (ATO) saving time and money.

21. Agency x has a need for
a new cloud based IT
system
Fed RAMP Authorization process:
Agency x gets security
requirements for the new IT
system from Fed RAMP and
adds requirements if necessary
Agency x releases REP
for new IT System and
awards contract to
cloud service provider
(CSP)
Agency X submits request to
Fed RAMP office for CSP to be
Fed RAMP authorized to operate
CSP is put into Fed RAMP priority queue
(prioritization occurs based on factors
such as multi-agency use, number of
expected users,etc.)

22. Fed RAMP AUTHORIZATION PROCESS (CONT):
CSP and agency
sponsor begin
authorization
process with Fed
RAMP office.
CSP agency sponsor and
Fed RAMP office review
security requirements
and any alternative
implementation.
Fed RAMP office
coordinators with CSP
for creation of system
security plan(SSP).
CSP has independent
assessment of security
controls and developers
appropriate reports for
submission for Fed
RAMP office.
Fed RAMP office
reviews and
assembles the
final authorization
package for the
JAB
JAB reviews final
certification package
and authorization CSP
to operate
Fed RAMP office adds CSP to
authorized system inventory
to be reviewed and leveraged
by all Federal agencies
Fed RAMP provide continuous
monitoring of CSP

23. Benefits of Fed RAMP:
Saves significant cost, time and resources “Do once
use many times”
Improves real-time security visibility.
Provides a uniform approach to risk-based
management.
Enhance transparency between government and cloud
service providers (CSPs)
Improves the trustworthiness,reliability,consistency
and quality of the Federal security authorization
process.

24. Final Word:
Without a doubt, Cloud Computing is Truly a
Revolutionary Concept for many Business Organization.
Because of the …,
 Technology's Ease of Adoption,
Significantly Lower Maintenance Costs and
Greater Workflow Efficiency.
There is no doubt that Cloud Computing will gain wide
Spread Popularity Going Forward…
