Hello list, Proposal for access control related to PC/SC smart cards follows.
I have no idea if it applies to PKCS#11 or not but I think somebody knowledgeable in this area should look into it ...
I'm sorry Honza :-) Petr^2 Spacek -------- Original Message -------- Subject: F21 System Wide Change: Access control in PCSC Date: Thu, 27 Feb 2014 16:59:14 +0100 From: Jaroslav Reznik <jrez...@redhat.com> Reply-To: de...@lists.fedoraproject.org Organization: Red Hat, Inc. To: devel-annou...@lists.fedoraproject.org = Proposed System Wide Change: Access control in PCSC = https://fedoraproject.org/wiki/Changes/PcscAccessControl Change owner(s): Nikos Mavrogiannopoulos <n...@redhat.com> Add access control to PC/SC smart cards available in the system. Adding access control would (a) prevent unauthorized processes/users from reading data on a smart card, (b) prevent unauthorized processes/users from erasing a smart card, (c) prevent unauthorized processes/users from talking to the smart card firmware. == Detailed Description == Add access control to PC/SC smart cards available in the system. Currently smart cards may provide their own access control for certain elements of a card such as a private key. Their access control method is typically a PIN, but can also be a biometric based one. That however, is not sufficient to prevent certain actions on the non-PIN protected elements. For example cards that provide a PKCS #15 filesystem can be modified by anyone that has access in the system (e.g., erased using pkcs15-init -E). The default settings allowed should be similar to the default settings for hard disks, i.e., root and the user in console should be able to access the smart card. Adding access control would * prevent unauthorized processes/users from reading data on a smart card * prevent unauthorized processes/users from erasing a smart card * prevent unauthorized processes/users from talking to the smart card firmware The way access control will be implemented is using polkit which is already being used to control access to hard disks. As smart cards share a lot with hard disks (e.g., a filesystem, and are inserted by the console user), sharing the same access control method is beneficial. == Scope == polkit support has to be added to PC/SC daemon. An initial version has already been developed and communicated upstream * Proposal owners: The polkit support has to be merged with the Fedora package. That requires changes to the pcsc daemon only, but indirectly all packages that potentially may use smart cards are affected (opensc, firefox, ...). * Other developers: Packages that use PC/SC smart cards must be checked that they work as expected after the access control change. * Release engineering: No coordination is required. * Policies and guidelines: If there is any security policy documentation should be updated to include the new policies on smart cards (I couldn't find any such documentation though) _______________________________________________ Freeipa-devel mailing list Freeipa-devel@redhat.com https://www.redhat.com/mailman/listinfo/freeipa-devel
