Re: Removing ping/icmp from a network

["Fabio Fagundes" <fabio.fagundes () gmail com>]

Hi all,

Please consider the risk of an intruder using ICMP as a Covert Channel
(http://en.wikipedia.org/wiki/Covert_channel).

Should one configure corporate routers to inspect and to rewrite ICMP
packets to avoid / reduce this risk ?

Regards,
Fabio.
