"The Internet Control Message Protocol may seem harmless at first glance.
Its goals and features were outlined in RFC 792 (and than later cleared in
RFCs 1122, 1256, 1349, 1812), as a way to provide a means to send error
messages, troubleshoot networking problems, and more.

There is no consent between the experts in charge for securing Internet
networks (Firewall Administrators, Network Administrators, System
Administrators, Security Officers, etc.) regarding the actions that should
be taken to secure their network infrastructure in order to prevent those
risks.

The risks involved in implementing the ICMP protocol in a network, regarding
scanning, are the subject of this research paper".
