Question

A company with a US-based sales force has requested that the VPN system be configured to authenticate the sales team based on their username, password and a client side certificate. Additionally, the security administrator has restricted the VPN to only allow authentication from the US territory. How many authentication factors are in use by the VPN system?

Answer 1

For a great security structure, THREE (3) AUTHENTICATION FACTORS ARE IN USE BY THE VPN SYSTEM.

The use of multiple authentication factors to prove one's identity is based on the premise that an unauthorized actor is unlikely to be able to supply the factors required for access. If, in an authentication attempt, at least one of the components is missing or supplied incorrectly, the user's identity is not established with sufficient certainty and access to the asset (e.g., a building, or data) being protected by multi-factor authentication then remains blocked.
