2. Project Goal Build a demonstration program to
study the concept of Cloud-based
Anti-Virus
A server utilizes current online Cloud-base AV engine (ClamAV, Symantec… )
Android client to sent file url to the server, receive result and take actions.
C++ is used for coding currently

3. Software Architecture

4. Current Progress Preparation 100% done
Setting up the cloud anti-virus environment. 100% done
Writing server(cloud) side code. Almost except communication part with client
Writing client side code. To do
Deploy the software on Ubuntu virtual machines. To do
Debugging. To do

5. Roadmap Tasks \ Time By 2/13 By 2/20 By 3/11 By 4/3 By 4/15 By 5/10
Preparation
Task 2 :
Setting environment
Task 3 :
Cloud Program
Task 4 :
Client Program
Task 5 :
Test and deploy

6. Task 1: Preparation
Investigate some current cloud based anti-virus engines. 100% done
ClamAV
Symantec Scan Engine
Decide the overall architecture of the software 100% done
Android users send a URL to the cloud.
Program running in the VM downloads the file and invokes different scan engines.
Send result back to the users.
User program take actions.

7. Task 2: Setting up environment
Step1:Install Ubuntu in VMware. 100% done
Step2:Download the newest Clamav scan engine and configure it. 100% done

8. Task 2: Setting up environment(cont)
Step3:Download libclamav package for development. 100% done
Step4:Download curl package. 100% done

9. Task 3: Building Server Program
Scan engine 1:Libclamav, licensed under GNU GPL v2
Step1: Get familiar with the ClamAV APIs 100% done
Head file
Initialization
Scan
Get feedback

10. Task 3: Building Server Program(cont)
Step2:Coding. 100% done
Step3:Compile and run the program.
100% done
Add another scan engine. To do

11. Difficulties Encountered
Some URL with JavaScript redirection feature can’t be downloaded by curl thus can’t be analyzed by ClamAV
Symantec Scan Engine still facing memory allocation error.

12. Task 4 : Building Client Software
To do next
Problems may encounter
How to get url from the user’s browser?
(Possible solution: Write an application with a browser component inside)
How to scan the files transmitted through Bluetooth or stored on Memory Card?
(Possible solution: Upload the file to the cloud for the file to be executed)

13. Task 5 : Testing and deployment
Combined test of client and server program. To do
Collect multiple virus samples to test its function. To do
Entering different type of URL to test.
Deploy this to the Mobicloud. To do

14. Thank you!
