    Security with apt
    Submitted by wyrmBait on Monday, April 08, 2002 – 15:28
    While reading this article over at Slashdot.org about the potential insecurity of creating a Single Point of Ownership, I couldn’t help notice the similarities between the offending program and our beloved apt. How secure is the protocol that apt uses? How resistant to attack are the Debian package servers? Is there any code signing done when a package is downloaded?

    I know I could get the answer to most of these from the source code, but I suspect the answers already, and would bring the question to the attention of more involved parties. Despite the fact that there are myriad package mirrors, many people (myself included) simply point apt to the main server, and, in any case, a package subverted in an attack on a main server could quickly propagate to the mirrors if it went undetected.

    IMHO, this is an issue that has been overlooked for some time is the context of open source, since the code is always there for inspection. The situation of automated updates does change things, though, and might require a re-examination of how much we trust pre-compiled code.

    Am I just being alarmist, or is this something that will have to be addressed in the development of Debian?

    Subject: signing packages with keys from website and/or .iso
    Author: kipple
    Date: Tuesday, 2002/04/09 – 12:21
    IMHO the security for the packages should be extended by using crypto and public key signing:
    1. the public key should be available on the website AND in every debian distro, so if the .iso are compromised we could always rely on the public key on the website, and vice versa;
    2. apt- should automatically check the sig for the packages using the pre-installed key and compare it with the key obtained from the website
    3. in this way if the website and/or any of the mirror are compromised, the debian community will notice it in very little time
    4. this could also lead to a better organization of packages, marking them as ‘approved by debian’. I know it could lead to discussion about ‘why was my package rejected?’, but still will centralize things

    ..those are just ideas, the methods could be discussed. I just would like to know if this makes sense or not

    greetings

    Subject: Signing should be done with GPG and public keys …
    Author: Anonymous

    …should be found in PGP-keyservers and therefore be themselves digitally signed with somone’s GPG public key which is known to the system. So one absolutely non-NSA-compromised known person’s GPG public key (keylenght >4096 bits) should come with the distribution and be found on mirror sites.
