Question

From a traffic flow perspective, what type of device exists immediately below the firewalls (in both the Agency and Base tiers) in the JRSS stacks?

Answer 1

In JRSS stacks, an Intrusion Prevention System (IPS) exists below the firewalls in both Agency and Base tiers, adding an extra layer of security by monitoring and preventing potential threats.

Step-by-step explanation:

In the JRSS (Joint Regional Security Stack) architecture, which is used for cybersecurity and network management within the Department of Defense, the device that typically exists immediately below the firewalls in both the Agency and Base tiers is an Intrusion Prevention System (IPS). An IPS is a critical component of the security stack that monitors network traffic to identify and prevent potential threats and malicious activities. By analyzing the traffic that passes through it, an IPS can block attacks that a firewall may not catch, thus adding a layer of security that is vital for protecting network resources.
