SECURITY
What is CLOUD COMPUTING?
The most demanding computing.
Cloud computing means storing and accessing data and
programs over the Internet instead of your computer's hard
drive. [5]
Features of cloud computing
 On demand-self service
 Broad Network access
 Resource pooling
 Rapid elasticity
 Measured service
 Pricing [10]
CHALLENGES
IN CLOUD COMPUTING
o Security
o Costing model
o Charging model
o Service level agreement
o Cloud interoperability issue [7]
What do we mean by
CLOUD SECURITY ?
 Set of control-based technologies and policies designed to adhere
to regulatory compliance rules and protect information, data
applications and infrastructure associated with cloud computing use.
 It can be done without the cost of maintaining facilities and
hardware.
 It addresses both physical
and logical security issues across
all service models of software. [3]
INTRODUCTION
 The Introduction of numerous cloud based services and
geographically dispersed cloud service providers, sensitive
information of different entities are normally stored in remote
servers.
 Locations with the possibilities of being exposed to
unwanted parties in situations where the cloud servers
storing those information are compromised. [1]
Sometimes, it might be required or at least possible
for a person to store data on remote cloud servers.
Sensitive States of cloud computing :
 The transmission of personal sensitive data to the cloud
server.
 The transmission of data from the cloud server to clients'
computers.
 The storage of clients’ personal data in cloud servers which
are remote servers, not owned by the clients. [1]
PROBLEM STATEMENT
Cloud security is becoming a key differentiator and
competitive edge between cloud providers. So by applying
the strongest security techniques and practices, cloud
security may soon be more secure than the level that IT
departments achieve using their own hardware and
software.
TYPES OF CLOUD
• Private cloud
--The cloud is managed by an organization and serves it solely.
• Public cloud
--The cloud infrastructure is owned and managed by a large
Cloud Service Provider (CSP).
• Hybrid cloud
--The cloud infrastructure is composed of two or more of the
above models.
• Community cloud
--The cloud is managed by several organizations and supports
a specific community that has the same interest. [7]
If security is not robust and consistent, the
flexibility and advantages that cloud computing
has to offer will have little credibility.
Here, we are going to discuss about the security
issues of cloud computing.
SECURITY MEASURES OF CLOUD
 User control.
 Investigative support, investigating inappropriate or
illegal activity may be impossible in cloud computing.
 Intrusion detection and prevention.
 Misconfiguration takes place, because lack of
expertise coupled with insufficient communication.
 Threat to access important information is also a
major concern which can lead to huge loss of data
and can even lead to hacking.
 Availability and backup. [23]
Four General Server Risks in Cloud
APPLICATIONS OF CLOUD COMPUTING
1) Cloud computing provides dependable and secure data
storage center.
2) Cloud computing can realize data sharing between
different equipments.
3) The cloud provides nearly infinite possibility for users to
use the internet.
4) Cloud computing does not need high quality equipment
for the user and it is easy to use. [3]
FUTURE SCOPE OF CLOUD SECURITY
 It is facing many challenges regarding the security of data.
 Modification of this technology helps to secure the data.
 Many research on this technology are taking place which
would eventually help this technology to expand its scope in
future leading to more secure data.
 Architectures , thus it will help to grow the IT industry as well
as advancement of this technology would help in big
organizations as well as full-fill the requirement of public industry
as well. [23]
STEPS TAKEN FOR BETTER CLOUD
 There are organizations working towards a more secure cloud, such
as the CSA (CLOUD SECURITY ALLIANCE).
 Another is Silver Sky, an expert provider of cloud security and
provider of “the industry’s only advanced Security-as-a-Service
platform from the cloud”.
 The CTO of Silver Sky, Andrew Jaquith, explains that many CIOs are
moving their services to the cloud in order to save money, but that
security remains a key concern and these moves may be insecure
or at least hasty.
 On the other hand, he also explains that many cloud service
providers are becoming clearer, more transparent, and more
assured than ever before that they could protect customer data.
SOLUTIONS OF ISSUES IN CLOUD
SECURITY
‼ Network and security audits
‼ Security threat assessments
‼ Secure network and infrastructure design
‼ Network perimeter protection, including firewalls and
intrusion detection
‼ Remote access strategies, including VPN implementations
‼ Data loss prevention for information in motion and at rest
[23]
CONCLUSION
 The Cloud provides many options for the everyday computer user
as well as large and small businesses.
 Clouds are more subjected to the data theft, malicious access, and
unsecured internet access.
 Efforts have been made to enforce confidentiality, integrity and
privacy of data.
 We have discussed the Issues, Factors Affecting the Data Security,
Threats to it, Measures being taken towards it, Applications of it as
well.
