Ballot SC3: Two-Factor Authentication and Password Improvements
Purpose of Ballot: The Network Security Working Group met a number of times
improve the Network Security Guidelines requirements around authentication,
specifically by requiring two-factor authentication, and improving the
requirements in line with more recent NIST guidelines.
While CAs are encouraged to improve their password requirements as soon as
possible, a two year grace period is being given to allow organizations to
develop and implement policies to implement the improved requirements,
since some organizations may have to simultaneously comply with other
compliance frameworks that have not been updated yet and are based on older
guidance about passwords.
The following motion has been proposed by Tim Hollebeek of DigiCert and
by Dimitris Zacharopoulos of Harica and Neil Dunbar of TrustCor.
¡ª MOTION BEGINS ¨C
This ballot modifies the ¡°Network and Certificate System Security
as follows, based upon Version 1.1:
In the definitions, add a definition for Multi-Factor Authentication:
"Multi-Factor Authentication: An authentication mechanism consisting of two
more of the following independent categories of credentials (i.e. factors)
verify the user¡¯s identity for a login or other transaction: something you
(knowledge factor), something you have (possession factor), and something
are (inherence factor). Each factor must be independent. Certificate-based
authentication can be used as part of Multifactor Authentication only if the
private key is stored in a Secure Key Storage Device."
Capitalize all instances of the defined term "Multi-Factor Authentication".
Add a definition for Secure Key Storage Device:
"Secure Key Storage Device: A device certified as meeting at least FIPS
level 2 overall, level 3 physical, or Common Criteria (EAL 4+)."
In section 1.j., capitalize Multi-Factor Authentication, and strike the
parenthetical reference to subsection 2.n.(ii).
In section 2.f., add "(for accountability purposes, group accounts or shared
role credentials SHALL NOT be used)" after "authenticate to Certificate
Change section 2.g. to read:
"g. If an authentication control used by a Trusted Role is a username and
then, where technically feasible, implement the following controls:
i. For accounts that are accessible only within Secure Zones or
Zones, require that passwords have at least twelve (12)
ii. For authentications which cross a zone boundary into a Secure
Zone or High
Security Zone, require Multi-Factor Authentication. For
from outside a Secure Zone or High Security Zone require
passwords that have
at least eight (8) characters and are not be one of the
four (4) passwords; and implement account lockout for failed
in accordance with subsection k;
iii. When developing password policies, CAs SHOULD take into
account the password
guidance in NIST 800-63B Appendix A.
iv. Frequent password changes have been shown to cause users to
secure passwords. If the CA has any policy that specifies
password changes, that period SHOULD NOT be less than two
April 1, 2020, if the CA has any policy that requires routine
changes, that period SHALL NOT be less than two years.
In section 2.h., change "Require" to "Have a policy that requires"
In section 2.i., change "Configure" to "Have a procedure to configure"
Change section 2.k. to read:
"k. Lockout account access to Certificate Systems after no more than five
access attempts, provided that this security measure:
i. is supported by the Certificate System,
ii. Cannot be leveraged for a denial of service attack, and
iii. does not weaken the security of this authentication control;"
Change section 2.n. to read:
"Enforce Multi-Factor Authentication for all Trusted Role accounts on
Systems (including those approving the issuance of a Certificate, which
applies to Delegated Third Parties) that are accessible from outside a
or High Security Zone; and"
