# Forescout: see first, then enforce, then orchestrate

Forescout is three products: see (eyeSight), enforce (eyeControl), orchestrate (eyeExtend). Dummy fs-em 10.10.10.30.

## The ticket

 Security asked for NAC. Networking heard 802.1X. Biomed heard “scanner.” Forescout can do all three badly if you enable Virtual Firewall on day one.

  Quick interview answer

  eyeSight  discovers and classifies IP-connected devices (docs: without agents; passive + careful active).  eyeControl  automates admission and post-admission actions.  eyeExtend  shares context and response with ISE, firewalls, ITSM. Enterprise Manager is the console brain; Appliances sit on spans and switch plugins — like PAN vs PSN, not identical.

 If you cannot classify it, do not Virtual-Firewall it.

## Three products

   Product  Job  This lab

  eyeSight  Discover, classify, posture  Always on
  eyeControl  Virtual FW, 802.1X, switch CLI, HTTP notify  Off until lesson 6
  eyeExtend  ISE / Palo Alto / ServiceNow  Lesson 8
  eyeSegment  Matrix segmentation (optional)  Mention only

  Like ISE personas — not the same

 EM vs appliance
  Enterprise Manager  console / policies

- Appliance fs-app1 span + plugin Switch / ISE enforce / RADIUS Rebooting EM because a span is dark is the wrong box. ## When to turn enforce on Week 1–2: discover only. Week 3: notify. Week 4+: Virtual FW or ISE handoff on known groups. Never enforce Unknown. https://fs-em.techclick-lab.in Training mock · not live Forescout Console Asset Inventory Policy Channels Tools Tools → Options → Modules ### Licensed modules eyeSight On eyeControl Installed, policies paused eyeExtend Cisco ISE Off until lesson 8 Cancel Save Forescout docs: eyeSight admin — discover/classify. Training mock. ## How you see it #### Side A — console Log into EM 10.10.10.30. Asset Inventory should start filling from the span on fs-app1.

- #### Side B — appliance Channel / interface: monitor (span) vs response (enforcement NIC). Do not put Virtual FW on the span NIC.

- #### Side C — prove Priya’s laptop and the printer appear with an IP and a first classification. No block actions yet.

## Four mix-ups

### 1 · Calling Forescout “just 802.1X”

### 2 · Enforce on day one

### 3 · EM down = “NAC down” while appliances still see

### 4 · eyeExtend fighting ISE on the same port

## How to prove it

  Close the intro only when

 1) You can say which product is on. 2) Inventory shows lab hosts. 3) No control action is hitting production VLANs. 4) You know EM ≠ appliance.

## Traps

   Phrase  Translate

  CounterACT  Older name for the platform / appliance
  eyeControl policy  The enforcement tree — not ISE policy set
  Virtual Firewall  Appliance inline/ACL-like control, not ASA

   Judgment items. One best answer. Reasons send you back to the matching section.

       Q1
       eyeSight’s job?

           Discover and classify
           Replace AD
           Terminate PEAP
           Be the WAN router

       Correct:  a . Docs.

       Q2
       eyeControl’s job?

           Enforce / automate control actions
           Only draw maps
           Only syslog
           Issue EAP certs

       Correct:  a . Concept.

       Q3
       eyeExtend’s job?

           Orchestrate ISE/firewall/ITSM
           Replace spanning-tree
           Hide NAT
           Run BGP

       Correct:  a . Concept.

       Q4
       Enterprise Manager is closest to…

           ISE PAN (console/policy)
           A switch access port
           MnT only
           A printer

       Correct:  a . SVG.

       Q5
       When do you enable enforcement?

           After you can classify and have a notify week
           During the first span cable
           On all Unknown hosts day one
           Never if ISE exists

       Correct:  a . Choose.

       Q6
       Virtual Firewall on the span NIC is wrong because…

           Monitor and response should be separate functions
           Forescout forbids all control
           Switches cannot span
           EM has no GUI

       Correct:  a . Runbook Side B.
