Talk:Covert channel

This article needs major revisions. It is not a good summary of existing work on covert channel. Even the definition part is not complete, making the following part confusing/misleading. In the literature, the term "covert channel" has several definitions that are not equivalent. Some of them, including the widely accepted one defined in the Orange Book, do not consider steganography as covert channels. In this sense, without clarifying the assumed definition, this article is flawed.  —Preceding unsigned comment added by 71.198.122.69 (talk) 08:20, 26 March 2008 (UTC)

message: This article is so incorrect that there may not be any sentences that can be salvaged.  I made a pass at fixing the main introduction.  It is written from the POV of cross domain solutions and trusting all the software to find the object hiding; not from sound COMPUSEC awareness.  We need to convert it to real covert channels.  Hopefully there is someone educated who can help.  John (talk) 04:35, 10 December 2009 (UTC)

message: Data hiding is an attack based on misuse of a legitimate data channel, categorically not a covert channel.  All the "Data Hiding" sections are misplaced in this article and I plan to delete them unless someone objects.  They may be excellent for another article.  John (talk) 06:24, 20 January 2010 (UTC)

"A similar case is port knocking. In usual communications the timing of requests is irrelevant and unwatched. Port knocking makes it significant."
I would fix to:

message: "a covert channel is a type of attack that creates a capability to transfer information objects between processes that are not supposed to be allowed to communicate by the computer security policy." But Covert channel is not an attack, or not only an attack, it is a vulnerability. I would fix to: "a covert channel is a vulnerability that allows to transfer information objects between processes that are not supposed to be allowed to communicate by the computer security policy. This can be due to a wrong design or to a specific attack."Truman (talk) 17:24, 4 March 2019 (UTC)
