You are required to secure a network against malware. You must ensure that in the event that a

compromised host is identified within the network. In this scenario after a threat has been

identified, which two components are responsible for enforcing MAC-level infected host ?

Show Suggested Answer Hide Answer
Suggested Answer: C, D

You are required to secure a network against malware. You must ensure that in the event that a compromised host is identified within the network, the host is isolated from the rest of the network. In this scenario, after a threat has been identified, the two components that are responsible for enforcing MAC-level infected host are:

C) Policy Enforcer. Policy Enforcer is a software solution that integrates with Juniper ATP Cloud and Juniper ATP Appliance to provide automated threat remediation across the network. Policy Enforcer can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies on the SRX Series devices and the EX Series devices. Policy Enforcer can also enforce MAC-level infected host, which is a feature that allows you to quarantine a compromised host by blocking its MAC address on the switch port.Policy Enforcer can communicate with the EX Series devices and instruct them to apply the MAC-level infected host policy to the infected host1.

D) EX Series device. EX Series devices are Ethernet switches that can provide Layer 2 and Layer 3 switching capabilities and security features. EX Series devices can integrate with Policy Enforcer and Juniper ATP Cloud or Juniper ATP Appliance to provide automated threat remediation across the network. EX Series devices can support MAC-level infected host, which is a feature that allows them to quarantine a compromised host by blocking its MAC address on the switch port.EX Series devices can receive instructions from Policy Enforcer and apply the MAC-level infected host policy to the infected host2.

The other options are incorrect because:

A) SRX Series device. SRX Series devices are high-performance firewalls that can provide Layer 3 and Layer 4 security features and integrate with Juniper ATP Cloud or Juniper ATP Appliance to provide advanced threat prevention. SRX Series devices can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies.However, SRX Series devices cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices3.

B) Juniper ATP Appliance. Juniper ATP Appliance is a hardware solution that provides advanced threat prevention by detecting and blocking malware, ransomware, and other cyberattacks. Juniper ATP Appliance can analyze the network traffic and identify the compromised hosts based on their behavior and communication patterns. Juniper ATP Appliance can also send threat intelligence feeds to Policy Enforcer and SRX Series devices to enable automated threat remediation across the network. However, Juniper ATP Appliance cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices.

That's a good point, Daryl. The Juniper ATP Appliance could definitely help in securing the network against malware.

Hmm, this seems like it's testing our knowledge of Juniper's security products. I'm familiar with the SRX Series and the EX Series, but the Juniper ATP Appliance and Policy Enforcer are new to me. I'll have to do some research on those before the exam.

Ugh, I hate questions that use so much technical jargon. 'MAC-level infected host'? What is this, a networking exam? I'm an IT generalist, not a network specialist. I'm just going to guess and hope for the best.

I feel like this question is trying to trip us up. What's the difference between a 'MAC-level infected host' and just a plain old infected host? I'm not sure I buy into this 'MAC-level' business. Maybe I'll just go with the two most 'security-sounding' options, B and C.

Okay, let's think this through step-by-step. We're looking for two components that can enforce security on a compromised host, and the options are SRX Series device, Juniper ATP Appliance, Policy Enforcer, and EX Series device. I'm leaning towards B and C, but I'm not 100% sure.

Hmm, this seems like a pretty technical question. I'm not sure I have the networking chops to answer it correctly. I might have to do some research on MAC-level security before taking this exam.

Whoa, this question is a tough one! Securing a network against malware is no easy task. I'm not sure I even know what 'MAC-level infected host' means, let alone which components are responsible for enforcing it.
