Exploitation

Lab

Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.

L2 attacks can take down networks — isolated lab only.

Learning L2 weaknesses on a lab switch — not on production home gear carelessly.

Use interactive mode on isolated lab topology; observe impact; document mitigations.

Home lab power users with managed switches should understand L2 risk.
