SI-4(3)

Requirement

Employ automated tools and mechanisms to integrate intrusion detection tools and mechanisms into access control and flow control mechanisms.

Discussion

Using automated tools and mechanisms to integrate intrusion detection tools and mechanisms into access and flow control mechanisms facilitates a rapid response to attacks by enabling the reconfiguration of mechanisms in support of attack isolation and elimination.
