Credentials theft is a big issue for the enterprise and sadly many enterprises don't have dual factor authentication for their users when they VPN in. This opens a big door for hackers that would easily play man in the middle on users, get their username and password. Often times, this username and password is the same one they use to VPN in.
Hackers get into the network using VPN with the stolen credentials and have free reign on the network. This is a big risk for organization. This class shows you have to configure Cisco clientless VPN using the privacy idea solution to authenticate the users using Multi Factor Authentication. The beauty of this solution is it doesn't cost a dime..
Imagine going to your boss and fixing their Dual Factor Auth for free - You will be a hero in everyones' eyes. Hope you enjoy.
