This begins the voting period for the Ballot SC29v3: System Configuration Management

Having consulted on-list to see if the voluntary moratorium on changes was over, I got no objection to proceeding with voting on this ballot, so here it is.
Purpose of Ballot:

Two sections of the current NSRs contain requirements for configuration management. Section 1(h) demands a weekly review and Section 3(a) a process to monitor, detect and report on security-related configuration changes.

There was consensus in the discussions of the Network Security Subgroup that unauthorized or unintentional configuration changes can introduce high security risks but the current wording allows CAs to comply with s1(h) without noticing such a change for several days. Whether the weekly human reviews have to be performed every 7 days or just once per week is a matter of interpretation but for the discussion of our proposal this is immaterial. The change we are proposing seeks to encourage CAs to rely on continuous monitoring rather than human reviews because alerts created by a continuous monitoring solution can notify a CA by orders of magnitude earlier than a human review i.e. within minutes not within days.

To answer the question as to whether automated patching via defined software vendor repositories is allowed: the answer is YES - this is allowed by the text of the ballot. The proposers and seconders publish no judgement on the desirability of such a process, but if it defined and documented per the terms of the ballot, such a process does not contravene the text of this ballot.
