This document summarizes a technical seminar presentation on security issues in cloud computing infrastructure as a service (IaaS). The presentation covers IaaS components and security drawbacks, literature reviewing approaches to monitoring service level agreements and strengthening network isolation, and the conclusions that each IaaS component poses security risks, cloud requires balancing cost, security and privacy, and changes in trust increase challenges.

3. Abstract
 This paper presents an elaborated study of IaaS
components security and determines its drawbacks and
its countermeasures.
Cloud Infrastructure as a Service (IaaS) helps agencies
realize cost savings and efficiencies while modernizing
and expanding their IT capabilities.
Cloud-based infrastructure is rapidly scalable, secure, and
accessible over the Internet — you only pay for what you
use.
 Infrastructure as a Service (IaaS) serves as the foundation
layer for the other delivery models, and a lack of security
in this layer will certainly affect the other delivery models.

4. Introduction
Why CLOUD COMPUTING?

5. “In simple words, the Cloud refers to the process
of sharing resources (such as hardware,
development platforms and/or software) over the
internet. It enables On-Demand network access.
These resources are accessed mostly on a pay-per-
use or subscription basis.”
 Cloud computing is a technology that uses the
internet and central remote servers to maintain data
and applications.

6. Cloud computing is much more efficient computing
by centralizing storage, memory, and processing .
Data isn’t “chained” to one place; rather, it can be
accessed anywhere, from any medium.
Processor speed becomes less important then
internet connection speed.
Low maintenance.

7. Why do customers use the cloud?
Cloud computing allows consumers and businesses to
use applications without installation and access their
personal files at any computer with internet access.

9. Cloud Delivery Models
IaaS(Infrastructure – as- a- Service)
A. Iaas is a provision model in which an organization used to support
operations, including storage, hardware, servers and networking
components.
B. The service provider owns the equipment and is responsible for running
and maintaining it .
C. The client typically pays on a per-use basis.

10. PaaS(Platform –as- a- Service)
A. PaaS is a way to rent hardware, operating systems, storage and
network capacity over the Internet.
B. Operating system features can be changed and upgraded frequently.
C. Initial and ongoing costs can be reduced while developing a software.
SaaS(Software –as- a- Service)
A. SaaS sometimes referred to as "software on demand," is software that
is deployed over the internet .
B. It is deployed to run behind a firewall on a local area network or
personal computer.
C. With SaaS, a provider licenses an application to customers either as a
service on demand, through a subscription, in a "pay-as-you-go"
model.
D.This approach to application delivery is part of the utility computing
model.

14. Security- Who is in control ?

15. Understanding Security of Cloud
Security in cloud computing is a major concern. Data in
cloud should be stored in encrypted form.
Since all the data is transferred using Internet, data
security is of major concern in cloud. Here are key
mechanisms for protecting data mechanisms listed below:
Integrity
Accountability
Privacy
Access Control
Authentication
Authorization

16. RESULT

17. Conclusion
Each component in Cloud infrastructure has its
drawbacks which might impact the whole Cloud’s
Computing security.
Cloud is a tradeoff between cost, security and privacy.
Change in trust boundaries leads to security and
privacy challenges.
