Army Knowledge Online (AKO) is the U.S. Army's main Intranet. It is said to be the world's largest corporate intranet.
The intranet is accessed through the Army's public Web page (also known as "AKO"), which it uses for recruiting and public information. Registering for an AKO account is mandatory upon enlistment in the army.
AKO access follows DoD security policy and requires a strong password or combination of a Common Access Card (CAC) smart card and personal identification number (pin). As of July 2010, soldiers must also answer 3 out of 15 personal questions of their own choosing in order to further validate access with knowledge-based authentication.
The main AKO intranet serves over 2 million registered users, including active duty and retired service personnel and their family members, and provides single sign-on access to over 300 applications and services. According to the Web site, AKO is the "pivotal tool" for use in "transforming the Army to a knowledge-based organization."
There is also a U.S. Navy Knowledge Online (NKO) and a U.S. Air Force portal. AKO has been expanded to the broader DoD community through Defense Knowledge Online (DKO).
