1. Seminar on
Secure Cloud
Presented by :-
1.Devyani B.
Vaidya.
Guided By:-
Prof. G. R.
Gosavi.

2. Contents
1. Introduction

3. Introduction
 Secure Cloud’s simple approach to data
protection safely delivers encryption keys
to valid devices without the need to
deploy an entire file system and
management infrastructure

4. Why Is There A Need For Cloud
Computing Backup?
 Backup services are also provided by cloud
computing and cover such functions like
availability of remote data, resiliency of data
center, compliance and security, server
performance, and data protection which are
especially practical and handy for business to
business backup.

5. Deployment Models
 Public
 Private
 Hybrid

6. Security Issues faced by Cloud
computing
1. Data Integrity
2. Data Theft
3. Privacy issues
4. Infected Application
5. Data loss
6. Data Location
7. Security on Vendor level
8. Security on user level

7. Risks of cloud computing
 Privacy agreement and service level
agreement.
 Security and data protection.
 Location of data.
 Loss Of Private/Important Data.

8. Why is Cloud Security Important
 Increasing Usage of Cloud Services in
Non-traditional Sectors
 Growing Adoption of Cloud Services in
Government Departments
 Rise in Cloud Service-specific Attacks
 Growing Usage of Cloud Services for
Critical Data Storage
 Rise in Employee Mobility

9. How to Secure Data on the Cloud
?
 Avoid storing sensitive information in
the cloud.
 Read the user agreement to find out
how your cloud service storage works.
 Be serious about passwords.
 Encryption.

10. Techniques Used To Encrypt Data
 The Caesar Cipher.
 Vigenere cipher.
 Rail Fence cipher.
 Steganography.

11. How To Encrypt file
 1. Choose the File that you want to
Encrypt .

12. Conti….
 2. choose any one algorithm .

13. Conti…
 3. choose format of Encryption.

14. Conti..
 4. Click on Encrypt.

15. Conti..
 5. After Encryption , Output.

16. Limitation..
 Secure Cloud Agent.
 Operating System.
 Volume Encryption.
 Boot Volume Encryption.

17. Conclusion..
 Thus We are Understand the concept of
cloud security and its encryption
technique . We also see that how to
encrypt our data before sending it on to
cloud.
