Data encryption is a method in which highly important and sensitive data is converted into unreadable form before its storage or transmission over the LAN/WAN. You can read encrypted data or decrypt it, if you have access to password or secret key.
Case Study: MCS folder have two files name mcs-morning and mcs-evening. User A wants to secure mcs-morning file from user B and all other users in the network. But user B also wants to secure mcs-evening file from user A and all other users in the network.
To implement this, first make a folder with name MCS folder and set NTFS permission as only administrator, user A, user B access MCS folder and administrator have full rights and user A and user B have modify permission on MCS folder. Now to secure files, login with user A and follow the given steps.
First open the MCS folder and right click on mcs-morning file then click on properties.
Click Ok button then apply.
Here system will ask you to secure the parent file and folder or only this file to secure data.
Now click Ok button to finish the user A settings.
Now to secure files, login with user B and follow the given steps.
First open the MCS folder and right click on mcs-evening file then click on properties.
Now click on advance button then check to encrypt content to secure data.
Click Ok button then apply.
Here system will ask you to secure the parent file and folder or only file to secure data.
Now click Ok button to finish the user B settings.
After implement encryption, user A can not read mcs-evening file and user B can not read the mcs-morning file.
Decryption of data
First open the MCS folder and right click on mcs-morning file then click on properties.
Now click on advance button then uncheck to encrypt content to secure data.
Click Ok button then apply.
Here your computer will ask you to decrypt the parent file and folder to insecure data then press Ok button to finish process.
