Last
week, I posted
that FERC will start auditing some entities for compliance with the NERC CIP
version 5 standards and also CIP-014 – and since then, I’ve been thinking about
what this means. It didn’t take much thinking to realize this will have a
profound impact on all NERC entities that need to comply with the CIP
standards. This post sets out steps I believe FERC needs to take in the near
term to address the primary problems with CIP v5.
First, it’s
important to know that FERC’s move will impact all NERC entities with CIP v5
obligations, even though it is clear they won’t be auditing all, or even the
majority of, entities. This is because I believe the mere fact that FERC may be their auditor will reset the
bar for compliance for most entities - since it is a fair assumption that
FERC’s auditors will be at least as strict as the Regional auditors, and often
more strict. All entities will now need to rethink their compliance programs
based on the assumption that FERC will be their auditor, not their Region (or
perhaps both, since FERC could conceivably just do one audit for an entity,
while leaving other audits to the Region. Hopefully, this is one issue that
will be addressed when FERC makes their announcement of this program).
FERC and
the entire NERC community are aware that compliance with the CIP version 5
standards is due starting April 1, 2016 – i.e., less than five months from now.
FERC is also undoubtedly aware that there are a number of serious
interpretation issues with CIP v5 that haven’t yet been addressed by NERC, and
are very unlikely to be addressed in any definitive way before April 1.
Moreover,
even if these issues are addressed before April 1, it may be too late. This is
because the big CIP v5 interpretation problems are all found in what I call the
fundamental requirements of v5 – the requirements that determine what cyber
assets are in scope for the standards, as well as whether or not they have
External Routable Connectivity (the concept of ERC doesn’t determine whether or
not a cyber asset is in scope for CIP, but it does determine how many
requirements are applicable to it). Since everything else that needs to be done
for v5 is based on how the entity complies with these fundamental requirements,
it is very likely not possible that an entity of any size can re-engineer its
compliance program now and still meet the 4/1/16 date, even if definitive
guidance comes out tomorrow on all of these problems.
This
means FERC will be auditing NERC entities for CIP v5 compliance, knowing they
haven’t had clear guidance on the meaning of the fundamental requirements in
question. These include CIP-002-5.1 R1 and Attachment 1 (and the definitions
that are integral to R1, including those of Cyber Asset, BES Cyber Asset and
BES Cyber System), as well as the different requirements that apply to BES
Cyber Systems with ERC.[i] Needless
to say, this is a problem.
How will FERC
deal with this problem? I can think of several ways:
1.
FERC could, in effect, say to the entities “Too bad you
didn’t have clear guidance on these issues when you needed it. But you’re still
in violation of the requirements as we interpret them.” I don’t think this will
win FERC too many friends; nor do I think they want to take this approach.
2.
Since the NERC Regional Entities have provided some guidance
to their members – either in public meetings or in private written
correspondence – FERC can say they will audit to that guidance, as long as it
is documented.[ii] The
problem here is that both NERC and the regions have also provided guidance that
isn’t documented in the Small Group Advisory Sessions (SGAS), as well as in
phone conversations and at meetings.[iii] What
will FERC do when an entity swears up and down that they were told during their
SGAS that procedure X is a good way to comply with requirement Y, yet FERC
(meaning the audit team) doesn’t agree with this interpretation? Does FERC
accept the entity’s word, or do they fall back on the approach described in
the previous bullet point? Frankly, I don’t believe either option would be
acceptable to FERC.
3.
FERC can put out their own “interpretations” of these
issues. For example, they can come out with their own “definitions” of
“Programmable” and “adverse impact on the BES”; they can provide their own
methodology for complying with CIP-002-5.1 R1;[iv] they
can provide their own interpretation of External Routable Connectivity;[v] etc.
I don’t
think it will shock you to hear that I think the third method is the only
workable one. But there is a problem with that as well: Given that FERC will be
changing the fundamental rules of the CIP v5 game less than five months before
the compliance date, they simply can’t expect entities to be compliant, based
on the guidance FERC does put out, by 4/1/16. I think FERC will need to
postpone the date on which v5 is enforced in some way.
I have
suggested one way this could be done, which is to have an “enforcement date”
for v5 one year after the “compliance date”. Since I was fairly sure that
wouldn’t happen, I had recently pointed out that
the “effective enforcement date” for v5 would be postponed regardless of any
official action; this refers to the date that the auditors will actually feel
comfortable issuing PVs for non-compliance. I think the effective enforcement
date will be after 4/1/16 because I believe auditors are unlikely to assess
violations for requirements where there is fundamental ambiguity – assuming the
entity has done all it could to come up with its own interpretation of the
ambiguous areas, while considering all available guidance from NERC and its
region.
However,
I’m certainly not ready to make this assumption about FERC auditors; they may
feel they have to issue violations whether or not there is ambiguity in the
requirement. As I said earlier, even if FERC were to release tomorrow a
complete set of interpretations of all the ambiguous requirements and
definitions in CIP v5, it may be too late for entities to revise their v5
programs to take advantage of those interpretations. This means FERC needs to
give them more time for compliance, whether through some formal Order or more
likely through an informal understanding. I don’t know the exact amount of
additional time that will be required for entities to come into full compliance
after 4/1/16 due to the ambiguity in the requirements; I’d say it’s at a
minimum six months, and probably closer to 12.
Note that
I’m not saying the compliance date needs to be pushed back for all of the CIP
v5 requirements; just those that are ambiguous enough that they require
guidance – including the requirements discussed above. To give an example of
how this might work for the “unambiguous” requirements (say for example the
requirements of CIP-009-6, Recovery Plans for BES Cyber Systems), I would say
the 4/1/16 compliance date can stand, provided FERC stipulates during an audit
that the entity has correctly complied with CIP-002-5.1 R1 and identified and
classified its BCS, including those with and without ERC. Once the
“Enforceable” date has been reached for CIP-002-5.1 R1 and other “ambiguous”
requirements, this stipulation can be removed and FERC can issue PVs for not
identifying BCS properly.
As FERC
probably realizes, what I’ve described above are short-term measures, designed
to allow CIP v5 to be rolled out without holding back enforcement until it can
be rewritten (since that will take years). In the second post, I will discuss
the longer-term measures that are required to have a sustainable NERC CIP
program. You may find what I say in that post to be surprising.
The views and opinions expressed here
are my own and don’t necessarily represent the views or opinions of Deloitte
Advisory.
[i] There
are certainly other areas of ambiguity in CIP v5. These will also have to be
dealt with, but they don’t affect all of the other requirements like these
“fundamental” requirements do.
[ii] Of
course, NERC has provided a number of guidance documents, including the Lessons
Learned, FAQs and the Memoranda. Since most of these are still in draft form or
have been withdrawn, and the few that have been finalized don’t address the
fundamental issues I’m referring to, I really can’t say that NERC has provided
documented guidance on these issues.
[iii] The
other problem is that even the documented guidance is almost always prefaced
with some statement that this is just the opinion of the individual providing
it, not of the Regional Entity. This of course is necessary since according to
the NERC Rules of Procedure, the only definitive “guidance” on the meaning of a
requirement is what is provided through the Request for Interpretation (RFI) process.
An RFI accepted today will likely take at least a year (and I’d guess more like
two years) to turn into an official, NERC and FERC-approved Interpretation. But
guidance on CIP v5 obviously can’t wait until a couple years after the
enforcement date.
[iv] As
I have been saying regularly, but most recently in this
post, the problem with interpreting this requirement is that there are so many
ambiguities and contradictions that no finite methodology could ever be written
down, that both could be followed and would be consistent with the words of the
requirement (and Attachment 1). However, there is a methodology that currently
guides how virtually all NERC entities are complying with the requirement. I
summarized that methodology in five steps near the beginning of the post just
referenced. I admit that was an over-simplification and there are probably more
like ten steps. I will do a post in the (reasonably) near future that will
outline what I consider a complete description of this methodology, which I’ll
call the “effective” CIP-002-5.1 R1 compliance methodology. I highly recommend
that FERC’s interpretation of R1 follow this methodology. After all, it’s the
one that the entities are using and the regions are teaching, even though the
methodology strays pretty far from the actual wording of R1 and Attachment 1.
There might be a methodology that could actually be followed that would be
closer to the wording. But to try to introduce that at this point – and
essentially require all entities with High and Medium assets to go back to
square one with their entire CIP v5 program – would be disastrous, in my
opinion.
[v] Of
course, I and many others think the discussion of Low-impact External Routable
Connectivity (LERC) in FERC’s NOPR on CIP v6 actually constitutes an
interpretation of the meaning of ERC as well. However, FERC needs to put out a
document explicitly addressing ERC.
