    1. 1. Mobile Cloud: Security Issues and Challenges Mrs. Vani, Mr. John & Mr. Manikandan Paper Presentation on
    2. 2. Evolution of Cloud Computing Mobile Cloud Computing Features Challenges Security Issues Existing Solutions Possible Solutions Conclusion Refernces CONTENTS
    3. 3. Cloud Computing - Evolution  Mainframe Computing - many users shared powerful mainframes using dummy terminals.  PC Computing - stand-alone PCs became powerful enough to meet the majority of users’ needs.  Network Computing - PCs, laptops, and servers were connected together through local networks to share resources and increase performance.
    4. 4. Cloud Computing - Evolution  Internet Computing - local networks were connected to other local networks forming a global network such as the Internet to utilize remote applications and resources.  Grid Computing - provided shared computing power and storage through a distributed computing system.  Cloud Computing - further provides shared resources on the Internet in a scalable and simple way.
    5. 5. Cloud Computing Common Location-independent Online Utility on Demand Common : implies multi-tenancy, not single or isolated tenancy Utility : implies pay-for-use on Demand : implies infinite, immediate, invisible scalability
    6. 6. Cloud Computing  Latest distributed computing model.  Implements the utility computing vision.  On-demand, pay-as-you-go, and utility computing.  A ubiquitous network access.  Objective - To increase the capacity and capabilities of client devices by accessing leased infrastructure and software applications instead of owning them.
    7. 7. Cloud Computing - Services A Few Services of Cloud:  SaaS - to use on demand software that is provided by the service provider via a thin client device for consumers  PaaS - applications deployed without the burden and cost of buying and managing the hardware and software for customers  IaaS - outsourcing of responsibility of equipment  MaaS, CaaS, LaaS, XaaS
    8. 8. Mobile Cloud Computing A new distributed computing paradigm for mobile applications whereby the storage and the data processing are migrated from the mobiles to resources rich and powerful centralized computing data centers in computational clouds. Aepona, “White paper, Mobile Cloud Computing Solution Brief”, November 2010.
    9. 9. Mobile Cloud Computing - Features  In MCC, these are Transferred to cloud  Intensive computing  Data storage  Information processing  Ubiquity and Mobility are two major features in next generation network.
    10. 10. Mobile Cloud Computing - Architecture
    11. 11. Mobile Cloud Computing -Characteristics  Scalability  Agility  Reliability  Security  Reduced Cost  Reduced Maintenance
    12. 12. Mobile Cloud Computing - Challenges  Limitation of bandwidth and communication latency  Signal Disturbance  Security  Limited power, memory, screen, OS  Low computing ability – Processing power  Quality of Service (affected by landforms, weather and buildings)
    13. 13. Mobile Cloud Computing - Challenges Limitations in contrast with PCs and Laptops  3 times less in processing capacity  8 times less in memory  5 to 10 times less in storage capacity  10 times less in network bandwidth
    14. 14. Mobile Cloud Computing –Security Layers Security Services are in three layers  Backbone layer – security surveillance in cloud physical system  Infrastructure layer – monitors VMs in cloud, storage verification, Evaluation and Audits, …  Application and Platform layer – user management, key management, authentication, authorization, encryption and data integration. Recent survey – 73% of IT executives and CEOs are unwilling to adopt cloud services due to privacy and security
    15. 15. Mobile Cloud Computing –Security Issues Security Issues in MCC  Data Ownership  Privacy  Data Security  Other security issues
    16. 16. Mobile Cloud Computing –Security Issues Security Issues in MCC  Data Ownership – MCC provides the facility to store personal data and other data (purchases) who owns the data? users need to be aware of different rights on purchases (Audio, Video, …).  Privacy – one of the biggest challenge Some apps store user’s data remotely, which may be sold to others (agencies ...) without the permissions of user. ( like updates about Location).
    17. 17. Mobile Cloud Computing –Security Issues  Data Security and Other security issues – Mobiles are famous for malicious code – gives possibility of loss.  Data loss from lost/stolen devices  Info stealing by malicious malware  Data leakage due to poorly written third party app  Unassured network access, unreliable APs  Insecure Market places  Near Field Communication and Proximity based hacking
    18. 18. Mobile Cloud – Existing Solutions  Anand Surendra – Secure framework to store data in secured fashion to protect user’s privacy.  Jibitesh Mishra – Secure architecture to maintain integrity and security of data.  Itani et. al – an energy efficient framework to assure user’s integrity.  Jon Oberheide – architecture with three components  Host Agent – lightweight process on device  Network Service – analyses what is sent by host  Cache - Global Shared & Local Private cache
    19. 19. Mobile Cloud – Existing Solutions  Chetan et. al – wildcat prevention and protection  Cloud access protection – OTP, OpAuTH  Embedded device identity protection – personalized profile on each device.  Marinelli – Hyrax, a MCC platform from Hadoop  Offers sane performance in data sharing  Allows users to utilize data and computing process on networks
    20. 20. Mobile Cloud – Possible Solutions Some steps for winning battle of breaches:  Prioritize the objectives and set the risk tolerance  there is no 100% secure.  Harddecisions on different levels of protection.  Protect data with proactive security plan  A plan with threat landscape in mind (hacking cyber crime, media & social scams, etc…)  With policies and technologies.
    21. 21. Mobile Cloud – Possible Solutions Some steps for winning battle of breaches:  Prepare the response to inevitable sophisticated attacks  Advanced continual threats need to be encountered.  Unified and tested response plan is needed.  Promote the culture of security awareness  Careless mistakes of individuals (an employee could affect master plan of CEO).  Build data security on culture of organization.
    22. 22. Conclusion  To attain more security and increase reliability  Threats need to be addressed & studied  Data security plan needs to be developed.  It is essential to keep in mind in designing a framework for MCC  More cost effective  More energy efficient  Better security  Better performance
