The IAO will ensure all AAA authentication services are configured to use two-factor authentication .

AAA network security services provide the primary framework through which a network administrator can set up access control on network points of entry or network access servers, which is usually the function of a router or access server. Authentication identifies a user; authorization determines what that user can do; and accounting monitors the network usage. Without AAA, unauthorized users may gain access and possibly control of the routers. If the router network is compromised, large portions of the network could be incapacitated with only a few commands.
