Back in May 2021, I sent <a moz-do-not-send="true"
href="https://lists.cabforum.org/pipermail/netsec/2021-May/000449.html"
class="">this message</a> to the NetSec Subcommittee
referring to RFC 3647 for guidance on the use of the terms
"audit log" and "records archival". In my understanding
the authors of RFC 3647 were trying to capture two
different sets of "evidence". Each set would need to
define the "types of events recorded/types of records
archived", the "retention period", the "protection"
controls, and the "backup" controls.<br class="">

class="">I agree that the authors of RFC 3647 intended for
more detail to be included in a CPS around each of these
sections than is currently in the BRs or added via the
proposed changes in this ballot, however I don’t believe that
RFC 3647 intends for 5.4 and 5.5 to represent two entirely
different sets of “evidence”. For example, in section 4.5.4
(“Audit Logging Procedures”) it indicates that coverage should
include “Frequency with which audit logs are processed or
archived”. Similarly, in 4.5.5 (“Records Archival”) the RFC
indicates that coverage should include “Types of records that
are archived, for example all audit data….”. These references
to archive and audits lead me to the interpretation that the
authors of RFC 3647 intended for the records archival process
to be an overarching collection and retention of audit data
(i.e. everything logged in section 5.4) along with other data
which may not be processed by event logging or audit systems
(such as documentation supporting certificate applications).
That is, as a Venn diagram, this is one circle inside another.
This ballot attempts to clearly outline the end result of this
relationship by delineating (and repeating, where relevant)
the categories of data accounted for in both sections 5.4 and
5.5. Given Aaron’s feedback, I definitely think there’s room
for improving <i class="">how</i><span style="font-style:
normal;" class=""> we outline that end result, however.</span></div>

scenarios and modernized validation/issuance processes, that
all data processed by the CA goes through event logging
systems, and therefore there would be no additional data
beyond audit data present in the records archive. I don’t
believe this ballot negatively impacts such a CA, but I would
love to hear if there are perceived unintended implications
from the proposed text which can be corrected.</div>

<font class="" color="#000000"><span style="caret-color: rgb(0,

to share here? FWIW, my understanding is that archival is,
as noted in 4.5.5 of RFC 3647, “records retention” — that
is, the continued possession and control of a collection of
records, typically (but not necessarily) on a less
frequently used storage medium. Perhaps this would be worth
including as a newly defined term, if there’s general
agreement that this represents what an archive is meant to
be in the context of 5.5?</span></font></div>

<br>
The notion of retention is also included in 4.5.4 in the phrase
"Period for which audit logs are kept" but I see your point.<br>
<br>
I believe the interpretation that audit logs (described in section
5.4 of the BRs) are a subset of records archival (described in
section 5.5) is fair and reasonable, and unless there are any
objections, we should adopt it as such in the BRs by providing the
necessary additional language. This will clarify the intent and
expectations from CAs and auditors evaluating these requirements.<br>
