The following are the prerequisites to integrate Active Directory with Cisco ISE.
+ Use the Network Time Protocol (NTP) server settings to synchronize the time between the Cisco ISE server and Active Directory. You can configure NTP settings from Cisco ISE CLI.
+ If your Active Directory structure has multidomain forest or is divided into multiple forests, ensure that trust relationships exist between the domain to which Cisco ISE is connected and the other domains that have user and machine information to which you need access. For more information on establishing trust relationships, refer to Microsoft Active Directory documentation.
+ You must have at least one global catalog server operational and accessible by Cisco ISE, in the domain to which you are joining Cisco ISE.

Explanation

There are three basic categories of attack: + volume-based attacks, which use high traffic to inundate the network bandwidth + protocol attacks, which focus on exploiting server resources + application attacks, which focus on web applications and are considered the most sophisticated and serious type of attacks Reference: https://www.esecurityplanet.com/networks/types-of-ddos-attacks/
