Ballot SC3: Two-Factor Authentication and Password Improvements

Purpose of Ballot: The Network Security Working Group met a number of times to

improve the Network Security Guidelines requirements around authentication,

specifically by requiring two-factor authentication, and improving the password

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, especially

since some organizations may have to simultaneously comply with other

compliance frameworks that have not been updated yet and are based on older NIST

guidance about passwords.

The following motion has been proposed by Tim Hollebeek of DigiCert and endorsed

by Dimitris Zacharopoulos of Harica and Neil Dunbar of TrustCor.

— MOTION BEGINS –

This ballot modifies the “Network and Certificate System Security Requirements”

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 or

more of the following independent categories of credentials (i.e. factors) to

verify the user’s identity for a login or other transaction: something you know

(knowledge factor), something you have (possession factor), and something you

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 140-2

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 Systems".

Change section 2.g. to read:

"g. If an authentication control used by a Trusted Role is a username and password,

    then, where technically feasible, implement the following controls:

  i. For accounts that are accessible only within Secure Zones or High Security

Zones, require that passwords have at least twelve (12) characters;

  ii. For authentications which cross a zone boundary into a Secure Zone or High

Security Zone, require Multi-Factor Authentication.  For accounts accessible

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 user's previous

four (4) passwords; and implement account lockout for failed access attempts

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 select less

secure passwords.  If the CA has any policy that specifies routine periodic

               password changes, that period SHOULD NOT be less than two years. Effective

               April 1, 2020, if the CA has any policy that requires routine periodic password

               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 (5) failed

    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 Certificate

Systems (including those approving the issuance of a Certificate, which equally

applies to Delegated Third Parties) that are accessible from outside a Secure Zone

or High Security Zone; and"
