Good idea. I will do that.

Hannes,

In the security considerations section, it would be worthwhile to indicate that the threats are addressed in details
in section 3.2 (Threat Descriptions) from [I-D.ietf-suit-information-model].

Denis
Hi Denis,

I think the risk of installing an old firmware version is covered in the information model document, which goes into the details of what a manifest has to contain. See Section 3.2.1 of https://tools.ietf.org/html/draft-ietf-suit-information-model-01

There are essentially three types of documents the working group is aiming to produce: an architecture document, the information model for the manifest and one or multiple serialization formats. You have been looking at the architecture but the appropriate document to read is the information model spec.

Ciao
Hannes

Subject: Re: [Suit] draft-ietf-suit-architecture-01

Hannes,

It is well known that software updates are often done to address a security issue. The same applies
to firmware updates. The current draft is lacking to address protections against the downloading of
an old firmware version. The threat should be mentioned in the security considerations section.

The main body of the document should mention mechanisms to prevent the replay of an old version
of the firmware.

Denis


Hi all,

I have just submitted version -01 of the architecture document. I have incorporate feedback from the working group, such as

*       New terminology,

*       Updates on the operating modes

*       New architecture figures,

*       New use cases (by David Brown)

Here is the new version:
https://tools.ietf.org/html/draft-ietf-suit-architecture-01

Here is the diff:
https://tools.ietf.org/rfcdiff?url2=draft-ietf-suit-architecture-01.txt

Feedback is appreciated.

Ciao
Hannes
