So, in the question, this is grace portal.
00:10
So, he already has ssl as a security measure.
00:15
Now, other than ssl, we can have two -factor authentication 2fa.
00:24
In 2fa, let's say this is a user and this is the portal.
00:34
We add an extra layer of security between the user to log in a portal.
00:42
So, in this extra layer, in this a unique code is sent to user before logging into the portal.
00:55
So, this unique code can be sent by sms or the email.
01:03
Only after verifying this unique code, user can log in into the portal.
01:08
Second one can be sftp protocol.
01:13
What is this? this means secure file transfer protocol.
01:26
In this, the data packets are first get encrypted.
01:33
Then only they are allowed to transfer in the network.
01:38
Also this sftp uses ssh environment.
01:43
What is this? this is a secure shell.
01:50
So, normal command line interface does not work in sftp.
01:54
We have to have ssh in order to communicate or manipulate this data.
02:00
So, environment is also secure and data is also encrypted.
02:06
This is how sftp protocol works.
02:08
So, other than ssl secure sockets layer, we can have two -factor authentication and sftp protocol as an additional security measures for the grace portal.
02:27
This is the two -factor authentication and this is secure file transfer protocol.
02:34
Now let's talk about davis.
02:35
This is grace portal and this is davis.
02:48
Now davis wants to communicate to this portal...
