Cloud computing delivers internet-based services like servers, storage, and applications, facilitating faster and more efficient IT solutions with various deployment models: public, private, and hybrid. Security challenges include data protection, user authentication, and the risk of data breaches, alongside issues like denial of service and malicious insiders. To ensure safe practices, cloud providers should obtain certifications demonstrating sound internal controls, and users must remain cautious of the associated risks.
Cloud Computing Security Challenges
- 2. What is Cloud Computing? Cloud is Common Location –independent Online Utility available on Demand Services. Cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications —are delivered to an organization's computers and devices through the internet. Cloud computing is the broader concept of converged infrastructure and shared services. It not just promises cheaper IT, but also faster, easier, more flexible and more effective IT. It is also versatile and flexible application of internet. This are fully managed by the cloud provider; the consumer requires only a computer and internet access.
- 3. Clouds can be classified as public, private or hybrid. Private Cloud (Low Security Risk): > Typically owned by the respective Enterprise. > Functionalities are not directly exposed to customers. Public Cloud ( More Security Risk ): > Enterprises may use Cloud functionalities from others . > Scope of functionalities may differ. Hybrid Cloud ( High Security Risk ): > Mixed employment of private & Public cloud. > Provide highly customized, enhanced offerings to local companies & world class application Deployment TypeDeployment Type

- 6. PaaS as well as SaaS are hosted on top of IaaS; thus, any breach in IaaS will impact the security of both PaaS and SaaS services. PaaS offers a platform to build and deploy SaaS applications, which increases the security dependency between them. These relationships and dependencies between cloud models may also be a source of security risks. A SaaS provider may rent a development environment from a PaaS provider, which might also rent an infrastructure from an IaaS provider. Each provider is responsible for securing his own services, which may result in an inconsistent combination of security models. It also creates confusion over which service provider is responsible once an attack happens.
- 7. Cloud computing security challenges fall into three broad categories: Data Protection > Securing your data both at rest and in transit. User Authentication > Limiting access to data and monitoring who accesses the data. Disaster and Data Breach > Contingency Planning.
- 8. Data breaches: > It is an incident in which sensitive, protected or confidential data has potentially been viewed, stolen or used by an individual unauthorized. Data loss: > Valuable data disappear into the ether without a trace. Account or service traffic hijacking: > An attacker gains access to your account, he or she can eavesdrop on your activities and redirect your clients to illegitimate sites. Insecure interfaces and APIs: > Cloud computing providers expose a set of software interfaces or APIs that customers use to manage and interact with cloud services.

- 9. Denial of service: > DoS outages can cost service providers customers and prove pricey to customers who are billed based on disk space consumed. Malicious insiders: > It can be a current or former employee, a contractor, or a business partner who gains access to a network, system, or data for malicious purposes. Cloud abuse: > A bad guy using a cloud service to break an encryption key which is too difficult to crack on a standard computer. Shared technology vulnerabilities: > Cloud service providers share infrastructure, platforms, and applications to deliver their services in a scalable way. Cont……Cont……
- 10. How to ensure Users that bothHow to ensure Users that both Data and Code are safe ?Data and Code are safe ? Very hard for the customers to actually verify the currently implemented security practices and initiatives of a cloud computing service provider because the customer generally has no access to the provider’s facility which can be comprised of multiple facilities spread around the globe. Solution: Provider should get some standard certificates from some governing institution that ensure users that provider has established adequate internal control and these control are operating efficiently.
- 11. ConclusionConclusion Cloud computing can be seen as a new phenomenon which is set to revolutionise the way we use the Internet, there is much to be cautious about. There are many new technologies emerging at a rapid rate, each with technological advancements and with the potential of making human’s lives easier. However, one must be very careful to understand the security risks and challenges posed in utilizing these technologies.
