<p>In a <a
href="https://www.forensicfocus.com/stable/wp-content/uploads/2011/08/cold_boot_attack_for_forensiscs1.pdf">research
report from 2011</a>, Defense Research and Development Canada concluded that
cold boot attacks can be useful in some cases to acquire data in memory but are
not a panacea and have many drawbacks dictated by the laws of physics, which
cannot be overcome by the technique. The authors recommend to only use cold
boot attacks as a last resort when all other avenues have been exhausted.</p>

This page describes some of the security measures built into Tails to protect from such attacks and explains how to access some types of resources on the local network.
