Kumar Mohit Sethi Filename : draft-irtf-t2trg-iot-seccons-10.txt Pages : 45 Date : 2018-02-12 Abstract: The Internet of Things (IoT) concept refers to the usage of standard Internet protocols to allow for human-to-thing and thing-to-thing communication. The security needs for IoT systems are well- recognized and many standardization steps to provide security have been taken, for example, the specification of Constrained Application Protocol (CoAP) secured with Datagram Transport Layer Security (DTLS). However, security challenges still exist, not only because there are some use cases that lack a suitable solution, but also because many IoT devices and systems have been designed and deployed with very limited security capabilities. In this document, we first discuss the various stages in the lifecycle of a thing. Next, we document the security threats to a thing and the challenges that one might face to protect against these threats. Lastly, we discuss the next steps needed to facilitate the deployment of secure IoT systems. This document can be used by IoT standards specifications as a reference for details about security considerations applying to the specified protocol.

However, security challenges still exist, not only because there are some use cases that lack a suitable solution, but also because many IoT devices and systems have been designed and deployed with very limited security capabilities. In this document, we first discuss the various stages in the lifecycle of a thing. Next, we document the security threats to a thing and the challenges that one might face to protect against these threats. Lastly, we discuss the next steps needed to facilitate the deployment of secure IoT systems. This document can be used by IoT standards specifications as a reference for details about security considerations applying to the specified protocol. This document is a product of the IRTF Thing-to-Thing Research Group (T2TRG).

Hi Stefan,

Thanks for the detailed review. We have submitted updated versions to address your concerns. You can find the latest version (-11) here: https://tools.ietf.org/html/draft-irtf-t2trg-iot-seccons-11 and the diff from the earlier version which you reviewed (-09) here:=C2=A0

https://tools.ietf= =2Eorg/tools/rfcdiff/rfcdiff.pyht?url1=3Dhttps://tools.ietf.org/id/draft-= irtf-t2trg-iot-seccons-09.txt&url2=3Dhttps://tools.ietf.org/id/draft-= irtf-t2trg-iot-seccons-11.txt

Here are our responses to your comments: 

I wasn't
clear who are the intended readers - if this is mainly
meant for the RG, then does it need to be an RFC? If
the intended readership is someone else, then who?
And will the current text be useful for that set of
folks?

The draft says in the abstract "This document can be used by IoT standards specifications as a reference for details about security considerations applying to the specified protocol.". Will this draft solve all the IoT security problems and save the world? No. That was never the intention. The draft provides a summary/collection of major security challenges for IoT and the existing tools and protocols that are available. This would serve as a good read for those designing new protocols. And instead of repeating many of the generic security considerations in each draft,=C2=A0 they could simply refer to this document.

(Note that I suggest referring to rfc 8240 and the LPWAN
overview draft and am an editor for both of those. I do
think they'd be good additions, but didn't want you to think
I'm sneakily trying to up my h-index:-)

They are now added at relevant places in the document.

- 50 pages, sheesh

The draft is currently 30 pages long with 10 pages of references. Yes, it is relatively long. But this an RG document that summarizes a lot of things.=C2=A0

- p1: crap code is surely the biggest security challlenge
=C2=A0 here, if this doc is to be useful it'll need to recognise that.

The draft says in section 3: "Vulnerable Software: Things in the Internet of Things rely on software that might contain bugs.=C2=A0 Th= is makes the things vulnerable to many different types of attacks, depending on the criticality of the bugs, e.g., buffer overflows or lack of authentication."

- p3: I don't see the point of sales-speak such as "The
=C2=A0 things that are part of the Internet of Things are no
longer unresponsive and have transformed into computing
devices that understand and react to the environment they
reside in."

Not a sales pitch but rephrased anyhow.

- p4, the lifecycle doesn't start when a tangible device is
=C2=A0 manufactured but rather when the oldest bit of code the
ends up in the device was written.=C2=A0 That's a significant
point, esp for smaller vendors who often re-use unpatched
old builds that "work" but may be wildly insecure.
- p4, I'd argue that the lifecycle could include some
recognition of OSS, but I'm not sure how to properly
include that.
- p4, the lifecycle could also include an on-the-shelf phase
=C2=A0 and a phase where a device is re-badged by some vendor who wasn't the actual original manuf.=C2=A0 Such phases can
significantly complicate s/w update and bootstrapping.
- p4, there are two other end-states that probably ought be
=C2=A0 part of the lifecycle - where a vendor end-of-life's a
device type that's still in use and where a device is simply
forgotten but keeps on trucking.

Good points. We have added a paragraph before Figure 1 stating that the described lifecycle is a simplified model that can be extended, e.g., with the situations that you describe.

- p7, section 2.2 seems pointless if it's not used later in
=C2=A0 the document - you may as well delete this. FWIW, I don't find figure 3 useful.

Removed.

- p9, the list seems to me to be very for-profit-vendor
=C2=A0 oriented.=C2=A0 I wonder would a non-profit or device-using<= br> organisation write a different list? I think they would,
e.g. they might include "crap s/w" and "attempted capture
via proprietary APIs/data formats/cloudy services" as
threats.

We do say that the list is not-exhaustive. Some of it has more to do with business security than actual device/system security.


- p11, I would argue that privacy deserves much more
=C2=A0 attention in this document than this, and that this
document isn't much use without that. For example, it's
important to include the scenario where a static sensor
emits a packet due to the presence/absence of people - in
that scenario anyone who can see that packet can potentially
invade the privacy of the people involved.=C2=A0 You do include
= more in section 5, but see my comment below about how that
section is(n't:-) organised.

We have added this example to Section 5.9.

- p20, "the fact is that many IoT devices and systems have
=C2=A0 very limited security." It seems a bit late to say this on page 20:-)

Added some text earlier in the document (for example, in the abstract).

- p21, I'm not sure an RFC is a good place to wonder about
=C2=A0 potential future regulation, unless that's to be done in a more thorough manner. I'd say deleting the last two
paragraphs of section 4.3 and replacing those with a single
sentence that "redional regulations aren't unlikely" might
be better.

Removed some text and added that regional regulations aren't unlikely.


- p22, I don't agree with the crypto points made (IMO, only
=C2=A0 devices that can verify an occasional signature ought be
= exposed to the Internet) - but even so the references here
aren't good - curve 25519 ought be the main ECC reference
relating to lessened CPU requirements. It's also a surprise
to not see a mention of chacha.

Added references to curve 25519 and chacha.


- p12, "Thus, ensuring a proper level of security in an IoT
=C2=A0 system at any point of time is challenging.=C2=A0 To address=
this challenge, a process for secure product creation is
required to ensure that an IoT system is secure and no
security risks are present." That's just silly - aiming for
a perfect system ("no security risks") is pointless as those
do not exist.

Rephrased

- p13, 4.1 should have some mention of LPWANs and indeed
=C2=A0 those deserve more text in general as the set of usable
security mechanisms and challenges differ in those parts of
networks.=C2=A0 You do mention LPWAN in 5.1.4 - which confused me as that text probably should be here in 4.x.=C2=A0 You might also wanna reference the LPWAN overview draft, currently in IETF
LC.

Added in 4.1.


- p16 and elsewhere - the state-of-the-art text should
=C2=A0 really try to indicate which things are or more, or less, importanct. That can be tricky, but e.g.=C2=A0 presenting HIP as being of equal importance to (D)TLS here isn't useful, nor
particularly credible. I also wonder if OSCOAP is as mature
and important as the text implies.

Text has been adapted to make clear that TLS, DTLS are the most important protocols. Wording is added to make clear that HIP is less relevant and OSCoAP is relatively new.

- p21, I don't get the logic behind the organisation of
=C2=A0 section 5, it seems to be a just-so list if things
described at fairly different levels of detail, e.g.=C2=A0 5.1 vs 5.2. I'd say a bit of thought as to how to organise this
section could lead to a better organised text.=C2=A0 I'm not sure how that'd be best done myself, but perhaps some discussion
within the RG would help there.

Section 5.2 is much shorter since the RG decided to include that material in a different Internet Draft.

- p24, homomorphic crypto? Huh? I don't buy= that at all.
=C2=A0 And following the [SEAL] reference leads to a dead end.
If you want to make a claim like this more detail would be
needed. I'd say deleting this is best.

The text says that it is limited in use. However, this is an area in which many people are working and thus, we would rather keep it. We have updated the reference. Microsoft updated it in the last months.<= br>
- p28 - how is referring to an expired draf= t from 9 years
=C2=A0 ago (yes, 2009!) useful?

Removed.

- p28, [iotsu] is better referred to via rf= c 8240 and I
=C2=A0 think a lot of the text in 5.4 is likely included in that report. The overlap is probably fine, but it'd be no harm to
just check to see if anything else from 8240 would be worth
including here.

Updated the reference to RFC 8240.

- p33, at the start of 5.9 "Users" is the wrong term, you
=C2=A0 should say "People" - that's not just a nit, but an
important difference (and one worth explicitly calling out)
as the people whose privacy is affected by devices need not
be "users" in any sense at all. Automatic number plate
scanners or camera based systems are usually good examples.
Updated as suggested.

- p34, in 5.10 you could add some mention o= f and reference
=C2=A0 to methods for h/w tamper detection/resistance.
=
Added


- p36 says "Thus, a potential approach is the definition and
=C2=A0 standardization of security profiles,..." That conclusion is not justified based on the text of this document.
(Where's there anything that implies that this conclusion is
warranted?) Secondly, I don't agree with the conclusion
itself - in the case of RPL that approach has lead to
nothing good happening that I've seen, and I'd expect it to
lead to more fig-leaves if applied in other cases. Now,
while I may be wrong, and your conlusion may be right, I
think I'm fairly safe in saying that much more justification
is needed before this conclusion could be credibly drawn.
Removed.

If you don't find some of your comments here, then we chose not to take any action on it. Please let us know if something is still needed.

Hiya,

Carsten asked me to take a look at this draft and
I said I would over the holidays, so I'm only a
wee bit later than promised:-)

In general, I think some more work is needed. Aside
from the specific points in the attached, I wasn't
clear who are the intended readers - if this is mainly
meant for the RG, then does it need to be an RFC? If
the intended readership is someone else, then who?
And will the current text be useful for that set of
folks?

Apologies in advance if some of the issues I raise
have been discussed in the RG before - I haven't
had time to participate in the RG to date. (I'm also
not subscribed to the RG list so please do cc me
on any follow ups.)

Cheers,
S.

So I'm not sure that the text in the abstract is really right, but maybe it's just me misinterpreting that. I do think this is a useful read for those writing code and specs for protocols in this space, but I do not think they can "simply refer to this" in order to deal with the challenges they face. If the abstract said this is background material but implementers and specification writers need to figure out and document their specific threat models, and mitigations based on those, then that'd be better. The reason I asked about this is that it's fairly common to find internet drafts where the security considerations just says "go read RFCxxxx" and I don't think pointers like that to this document would be a good outcome here. >=20 >> (Note that I suggest referring to rfc 8240 and the LPWAN >> overview draft and am an editor for both of those.

Yes, that is point#10 in section 3. Personally I think that's the biggest challenge in this space and deserves to be better highlighted. And it's not simply vulns, (all systems will have some CVEs) - some of the code we've seen deployed really is just very very crappy e.g. with default admin/admin access exposed to the Internet in gazillions of cameras all findable via shodan. IMO such cases aren't really "bugs." I forget if the draft says somewhere that if you deploy crap, that will be found and exploited, but it probably ought. And a couple of pointers to examples of that having happened would be good too. >=20 >> - p3: I don't see the point of sales-speak such as "The >> =C3=82=C2=A0 things that are part of the Internet of Things are no >> longer unresponsive and have transformed into computing >> devices that understand and react to the environment they >> reside in." >=20 > Not a sales pitch but rephrased anyhow. >=20 >> - p4, the lifecycle doesn't start when a tangible device is >> =C3=82=C2=A0 manufactured but rather when the oldest bit of code the >> ends up in the device was written.=C3=82=C2=A0 That's a significant >> point, esp for smaller vendors who often re-use unpatched >> old builds that "work" but may be wildly insecure. >> - p4, I'd argue that the lifecycle could include some >> recognition of OSS, but I'm not sure how to properly >> include that. >> - p4, the lifecycle could also include an on-the-shelf phase >> =C3=82=C2=A0 and a phase where a device is re-badged by some vendor wh= o >> wasn't the actual original manuf.=C3=82=C2=A0 Such phases can >> significantly complicate s/w update and bootstrapping. >> - p4, there are two other end-states that probably ought be >> =C3=82=C2=A0 part of the lifecycle - where a vendor end-of-life's a >> device type that's still in use and where a device is simply >> forgotten but keeps on trucking.=20 >=20 > Good points.

I'd highlight it more, but that's maybe a matter of opinion. For me, figure 1 still seems too much focused on what larger manufs will/can do for sets of devices sold to larger customers. >=20 >> - p7, section 2.2 seems pointless if it's not used later in >> =C3=82=C2=A0 the document - you may as well delete this.

I still think there'd be value in the RG trying to reflect inputs here from open-source developers, individual end users and maybe pentesters. Did anyone try get review from such folks? (Note: I'm not saying I know what they'd say, or if it'd make much difference, but I do wonder.) >> - p11, I would argue that privacy deserves much more >> =C3=82=C2=A0 attention in this document than this, and that this >> document isn't much use without that.

I still think the RG should consider whether to make a strong recommendation that devices that are incapable of verifying a reasonable signature are really highly likely to cause trouble. IOW, couldn't the RG RECOMMEND that such devices ought not be even indirectly exposed to the Internet, given the real-world threats faced? If the RG did have consensus on that, then that would I think help those developing standards and subsequent users of devices built to those standards. >=20 >> >> - p12, "Thus, ensuring a proper level of security in an IoT >> =C3=82=C2=A0 system at any point of time is challenging.=C3=82=C2=A0 T= o address >> this challenge, a process for secure product creation is >> required to ensure that an IoT system is secure and no >> security risks are present."

I think it'd be useful to explicitly point out the difference though - the set of people affected by devices can be much bigger than the set of users of those devices, and implementers and people writing standards ought to, but perhaps don't, consider both, esp. when it comes to privacy issues. >=20 >> - p34, in 5.10 you could add some mention of and reference >> =C3=82=C2=A0 to methods for h/w tamper detection/resistance. >=20 > Added >=20 >> >> - p36 says "Thus, a potential approach is the definition and >> =C3=82=C2=A0 standardization of security profiles,..."

Thanks. That does leave section 6 without "next steps" though doesn't it? I guess you could say that implementers and those writing spec need to consider how all of these issues (and those that emerge later) affect their work, and need to devote real effort to addressing these issues, and (for the spec writers) say how they've done that, so that those reading and implementing are less likely to screw up yet again;-) Cheers, S. >=20 > If you don't find some of your comments here, then we chose not to take= > any action on it.

Hi Stephen,

I still think the RG should consider whether to make a strong
recommendation that devices that are incapable of verifying a
reasonable signature are really highly likely to cause trouble.
IOW, couldn't the RG RECOMMEND that such devices ought not be
even indirectly exposed to the Internet, given the real-world
threats faced? If the RG did have consensus on that, then that
would I think help those developing standards and subsequent
users of devices built to those standards.

- p12, "Thus, ensuring a proper level of security in an IoT
=C3=82=C2=A0 system at any point of time is challenging.=C3=82=C2=A0 To a=
ddress
this challenge, a process for secure product creation is
required to ensure that an IoT system is secure and no
security risks are present." That's just silly - aiming for
a perfect system ("no security risks") is pointless as those
do not exist.


        

        
Rephrased



        

          
- p13, 4.1 should have some mention of LPWANs an=
d indeed
=C3=82=C2=A0 those deserve more text in general as the set of usable
security mechanisms and challenges differ in those parts of
networks.=C3=82=C2=A0 You do mention LPWAN in 5.1.4 - which confused me
as that text probably should be here in 4.x.=C3=82=C2=A0 You might also
wanna reference the LPWAN overview draft, currently in IETF
LC.=20


        

        
Added in 4.1.



        

          
- p16 and elsewhere - the state-of-the-art text should
=C3=82=C2=A0 really try to indicate which things are or more, or less,
importanct. That can be tricky, but e.g.=C3=82=C2=A0 presenting HIP as
being of equal importance to (D)TLS here isn't useful, nor
particularly credible. I also wonder if OSCOAP is as mature
and important as the text implies.


        

        
Text has been adapted to make clear that TLS, DTLS are the most
important protocols. Wording is added to make clear that HIP is less
relevant and OSCoAP is relatively new.



        

          
- p21, I don't get the logic behind the organisa=
tion of
=C3=82=C2=A0 section 5, it seems to be a just-so list if things
described at fairly different levels of detail, e.g.=C3=82=C2=A0 5.1 vs
5.2. I'd say a bit of thought as to how to organise this
section could lead to a better organised text.=C3=82=C2=A0 I'm not sure
how that'd be best done myself, but perhaps some discussion
within the RG would help there.


        

        
Section 5.2 is much shorter since the RG decided to include that
material in a different Internet Draft.



        

          
- p24, homomorphic crypto? Huh? I don't buy that=
 at all.
=C3=82=C2=A0 And following the [SEAL] reference leads to a dead end.
If you want to make a claim like this more detail would be
needed. I'd say deleting this is best.


        

        
The text says that it is limited in use. However, this is an area in
which many people are working and thus, we would rather keep it. We have
updated the reference. Microsoft updated it in the last months.


      

      
My scepticism remains unchanged:-)

I don't think this is useful background for the intended
audience until after someone has documented a usable scheme
e.g. via a CFRG RFC.



      

        

        

          
- p28 - how is referring to an expired draft fro=
m 9 years
=C3=82=C2=A0 ago (yes, 2009!) useful?


        

        
Removed.



        

          
- p28, [iotsu] is better referred to via rfc 824=
0 and I
=C3=82=C2=A0 think a lot of the text in 5.4 is likely included in that
report. The overlap is probably fine, but it'd be no harm to
just check to see if anything else from 8240 would be worth
including here.


        

        
Updated the reference to RFC 8240.



        

          
- p33, at the start of 5.9 "Users" is the wrong =
term, you
=C3=82=C2=A0 should say "People" - that's not just a nit, but an
important difference (and one worth explicitly calling out)
as the people whose privacy is affected by devices need not
be "users" in any sense at all. Automatic number plate
scanners or camera based systems are usually good examples.


        

        
Updated as suggested.


      

      
Thanks. I think it'd be useful to explicitly point out the
difference though - the set of people affected by devices can
be much bigger than the set of users of those devices, and
implementers and people writing standards ought to, but perhaps
don't, consider both, esp. when it comes to privacy issues.



      

        

        

          
- p34, in 5.10 you could add some mention of and=
 reference
=C3=82=C2=A0 to methods for h/w tamper detection/resistance.


        

        
Added



        

          
- p36 says "Thus, a potential approach is the definition and
=C3=82=C2=A0 standardization of security profiles,..." That conclusion
is not justified based on the text of this document.
(Where's there anything that implies that this conclusion is
warranted?) Secondly, I don't agree with the conclusion
itself - in the case of RPL that approach has lead to
nothing good happening that I've seen, and I'd expect it to
lead to more fig-leaves if applied in other cases. Now,
while I may be wrong, and your conlusion may be right, I
think I'm fairly safe in saying that much more justification
is needed before this conclusion could be credibly drawn.


        

        
Removed.


      

      
Thanks. That does leave section 6 without "next steps"
though doesn't it? I guess you could say that implementers
and those writing spec need to consider how all of these
issues (and those that emerge later) affect their work,
and need to devote real effort to addressing these issues,
and (for the spec writers) say how they've done that, so
that those reading and implementing are less likely to
screw up yet again;-)

Cheers,
S.

Hiya,

Carsten asked me to take a look at this draft and
I said I would over the holidays, so I'm only a
wee bit later than promised:-)

In general, I think some more work is needed. Aside
from the specific points in the attached, I wasn't
clear who are the intended readers - if this is mainly
meant for the RG, then does it need to be an RFC? If
the intended readership is someone else, then who?
And will the current text be useful for that set of
folks?

Apologies in advance if some of the issues I raise
have been discussed in the RG before - I haven't
had time to participate in the RG to date. (I'm also
not subscribed to the RG list so please do cc me
on any follow ups.)

Cheers,
S.

I agree that any "baseline" crypto capability recommendation
would need such exploration and justification. OTOH, we do
kinda know that s/w update pretty much needs signatures, which
is why I suggest that the ability to verify some signatures
at some time(s) could be a good baseline capability to consider.
(That's not to suggest that all inbound messages to all devices
be signed, as that'd not be a good plan:-)

What I'm suggesting is that the RG do the exercise of trying
to see if such a baseline could be usefully described. (And as
I'm not on the RG list, it could be that that's been discussed,
but if so, that's not visible in this draft.)

Cheers,
S.

Here is my usual eclectic condensed agenda based on the "FINAL" AGENDA
for IETF101.  Remember that "FINAL" means this will be the basis for
printed agenda sheets, there is still some potential for changes after
that.

SUIT is now on top of CORE (!??).

(Also, ICE has moved.)  The painful ones this time include: DINRG
vs. ACE, CBOR vs. TEEP, ROLL vs. traveling to OCF/WoT; also CORE
vs. ANIMA, CORE vs. QUIC, CORE vs. SECDISPATCH.

All times are actually in GMT (UTC+0000, DST only starts in London on
March 25).  (You can always get pure UTC times on
https://datatracker.ietf.org/meeting/agenda-utc, for those who want to
listen from remote.)

Abstract:
   The Internet of Things (IoT) concept refers to the usage of standard
   Internet protocols to allow for human-to-thing and thing-to-thing
   communication.  The security needs for IoT systems are well-
   recognized and many standardization steps to provide security have
   been taken, for example, the specification of Constrained Application
   Protocol (CoAP) secured with Datagram Transport Layer Security
   (DTLS).  However, security challenges still exist, not only because
   there are some use cases that lack a suitable solution, but also
   because many IoT devices and systems have been designed and deployed
   with very limited security capabilities.  In this document, we first
   discuss the various stages in the lifecycle of a thing.  Next, we
   document the security threats to a thing and the challenges that one
   might face to protect against these threats.  Lastly, we discuss the
   next steps needed to facilitate the deployment of secure IoT systems.
   This document can be used by implementors and authors of IoT
   specifications as a reference for details about security
   considerations while documenting their specific security challenges,
   threat models, and mitigations.

   This document is a product of the IRTF Thing-to-Thing Research Group
   (T2TRG).

Dear all,

The  document "Inter-network Coexistence in the Internet of Things" 
describes key challenges for coexistence for _administratively 
independent_ IoT networks sharing unlicensed spectrum.

Recent research results (our own and others) demonstrate the impact of 
protocol-level interactions on network performance.  A better 
understanding of these issues is needed to ensure successful deployment 
of IoT applications.

The document identifies two opportunities for the IRTF T2TRG community. 
The first is to define best practices for performance evaluation and 
protocol design in the context of network coexistence.  The second is to 
investigate the use of higher layer protocols to actively participate in 
managing network coexistence.

Version -01  (2017/10/30) is available at
https://tools.ietf.org/html/draft-feeney-t2trg-inter-network-01
Comments are most welcome.

If there is interest in further discussions, I will plan to be at the 
London meeting next month.

Regards,
Laura

Thanks, I found that to be a useful summary of the issues and to have some
good pointers.   I'd like to add one potential work item, though, before
"define best practices for performance evaluation":  "describe what a
useful lab setup would look like".  Looking back at our own experience at
building a lab, it strike me that we have many of the elements you describe
but lack one:  we have multiple, heterogeneous networks in a variety of
topologies, but we also have a single higher-order administration.  So we
may actually be scheduling away some of the real-world implications by
parceling out project activity in the lab.

Thoughts on how to avoid that from the group would make a good addition
(either to your doc or to the best practices doc).

regards,

Ted
