Hi everyone, good to see you again. Today, I'll take a closer look at mcloudoc information leakage prevention. Nowadays, there are a variety of cloud services as well as computer peripheral equipment and the internet. So the paths for information leakage are increasing. mcloudoc is a very good solution to crack down on every channel of this information leakage without a separate security solution.
Then, mcloudoc’s prevention for information leakage! How is it different? Let’s take a look at it in a moment.
#2. Computer peripheral equipment information leakage prevention
First, let me copy the centralized document to the USB memory and smart phone that you use the most.
I tried to copy it to USB memory but it fails. I also try to copy it to my smartphone, but it fails. In addition to this, the document can’t be copied to the CD drives, network drives, or external hard disks. We also block information from being copied to various media such as infrared ports, Bluetooth, and so on.
#3. PC storage prohibition
For example, documents from programs such as MS Office or CAD, the programs you specify for your business, cannot be saved if you save the document to the C drive. So, you can save it in the central drive provided by mcloudoc such as the X, Y, or Z drive. This centralized document can only be read by programs that are allowed to be input/output from the center. When you try to save this read document back to the C drive, there is an error and you cannot save it. If you try to save this on a USB, network drive, or SD card as well as this (C:) drive, it will not be saved due to an error.
Here is another tip. Since ClouDoc controls this application, if you do not want the document to be leaked through the network, you can disable central input/output for a program that has a network transmission function. This is also a way to block information leakage through the network.
#4. Block clipboard copy, screen capture, print
Next, let's see clipboard copy, screen capture, and print block functions. MS Office input/output allowed I/O only centrally, while Notepad allowed only local disk I/O. So when I try to copy the contents of MS Word to the clipboard and paste it into Notepad, it fails. This time, let's take a look at screen capture.
I selected the screen capture tool to capture MS Word, and the MS Word document became black, which enabled capture. And when you look at the print section, I get an error when I try to select a printer to print it out. So in mcloudoc, you can specify a useable printer, or you can specify a printable program for each printer so that only those programs can print.
#5. Web mail/ Web bulletin information leakage prevention
You cannot copy a centralized document to a medium such as USB, and if you try to attach a document to the web, the error also occurs. If I try to attach a document to Google Mail without permission to export it, then I get an error. And when I try to attach the file to a Google blog site without permission, I also get an error.
Like this, information leakage through the Web is prevented.
#6. Messenger information leakage prevention
This time it’s messenger. Let's try to attach the centralized document to ‘Skype’. At the current setting, ‘Skype’ cannot read the centralized document because it is not on the WhiteList. So the attachment fails. Messengers such as ‘MSN Messenger’, ‘KakaoTalk’, ‘LINE’, ‘WeChat’, and ‘WhatsApp’ as well as ‘Skype’ are also not included in the WhiteList, so you can block information leaks.
#7. FTP information leakage prevention
Let's also look at FTP. Let me try to send a document through ‘filezilla’, which you know well. As you can see, you cannot send documents from a central drive to the outside via ‘filezilla’. This is also because ‘filezilla’ is not included on the WhiteList and cannot be read. Next, there is the FTP function provided by Microsoft Windows Explorer itself. This Windows Explorer is included in the WhiteList. So I try to use this to send a document. I used the FTP function here and it pops out to a web browser. This is because mcloudoc has blocked the FTP function in Windows Explorer.
#8. VM CDI information leakage prevention
Yes! ‘VMWare Workstation’ is installed on this computer. So there is a physical PC and there is one virtual machine in it. I will copy the document from the virtual machine and paste it into the physical PC. It does not copy. Conversely, even when there is a central drive in the physical PC, copying to the virtual machine is also blocked. When using the VDI environment, you can block the movement of files between the virtual machine and the physical PC in the same way to prevent information leakage.
#9. Remote desktop connection information leakage prevention
Your PC has a remote desktop feature. So anyone outside can log in via the remote desktop and use your PC. At that time, that person’s local disk (C :) can be displayed as a Windows Explorer drive in the remote desktop connection state. When I tried to copy the central drive document there, it’s blocks me. Also, if that person tries to copy the contents of the document in the remote desktop while connecting by copying the contents to the clipboard to his or her PC, it will also be blocked.
#10. Cloud information leakage prevention
Nowadays, there are a lot of problems in terms of cloud service information leakage prevention. Cloud services, of course, can create a low-cost, efficient work environment, but they can be vulnerable to information leakage. So information leakage is at your employee’s fingertips. Let me show you how we can block information leakage for a few cloud services.
If you see Google Drive, a program called ‘Backup and Sync’ will run. So even if you set the folder to backup, the Backup and Sync program is not on the WhiteList, so you cannot export the information.
Next, let's look at the ‘ONE drive’ from Microsoft. ‘ONE drive’ is also programmed. So if you try to upload to this ‘ONE drive’, you will not be able to leak information because ONE drive cannot read the centralized document.
Recently, many programs such as ‘dropbox’ have been plugged into Windows Explorer. It's on the WhiteList, but you can see that when you attempt to copy a centralized document to a plugged in ‘dropbox’, it will not be copied. This prevents information leakage on cloud services! mcloudoc also provides this functionality.
#11. Information leakage prevention by other programs
In addition to the programs I have explained so far, there are P2P programs such as ‘uTorrent’ and ‘Bittorent’, and remote support programs such as ‘TeamViewer’ or ‘rusupport’ for remote support of customers. Many other programs are free from information leakage because they are not part of mcloudoc's WhiteList.
#12. Application for document export
Here, the process of document export was not fully explained due to time constraints. Documents approved by the team leader can be exported as a web page, you can export them to USB or PC hard disk, transfer or take them to the outside.
#13. Ransomware blocking
You might be wondering about the Ransomware protection. Ransomware is one of the most dangerous malicious codes in that it does not leak information but it destroys it. There is a separate video for Ransomware on our homepage so please refer to that video.
#14. Separation of intranet and internet
This is one of the other features I did not demonstrate today as I'll have time to introduce it in a separate video later. There is a network separation function that completely separates the intranet and internet from the PC by software. This network separation function can be used as a personal information security function and can be used as a comprehensive function for preventing information leakage by malicious codes.
I will introduce this feature later.
I explained mcloudoc information leak prevention functions today and I hope it was helpful. Let me ask you today's question. ‘Can document centralization replace media control solutions and DRM solutions?’ Please leave a comment below the video. I hope that it will be a forum for quality discussions between you all and myself.
Thank you for watching. Please subscribe to the mcloudoc channel and please click the like button. I'll see you in the next video.
