Login Security Extension for the Extensible Provisioning Protocol (EPP)
draft-gould-regext-login-security-03
Abstract
The Extensible Provisioning Protocol (EPP) includes a client
authentication scheme that is based on a user identifier and
password. The structure of the password field is defined by an XML
Schema data type that specifies minimum and maximum password length
values, but there are no other provisions for password management
other than changing the password. This document describes an EPP
extension that allows longer passwords to be created and adds
additional security features to the EPP login command and response.

1. Introduction
This document describes an Extensible Provisioning Protocol (EPP)
extension for enhancing the security of the EPP login command in EPP
RFC 5730. The enhancements include supporting longer passwords (or
passphrases) than the 16-character maximum and providing a list of
security events in the login response. The password (current and
new) in EPP RFC 5730 can be overridden by the password included in
the extension to extend past the 16-character maximum. The security
events supported include: password expiry, client certificate expiry,
insecure cipher, insecure TLS protocol, new pasword complexity, login
security statistical warning, and a custom event. The attributes
supported by the security events include identifying the event type
or sub-type, indicating the security level of warning or error, a
future or past-due expiration date, the value that resulted in the
Gould & Pozun Expires July 19, 2019 [Page 2]
Internet-Draft loginSec January 2019
event, the duration of the statistical event, and a free-form
description with an optional language.
1.1. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
XML is case sensitive. Unless stated otherwise, XML specifications
and examples provided in this document MUST be interpreted in the
character case presented in order to develop a conforming
implementation.
In examples, "C:" represents lines sent by a protocol client and "S:"
represents lines returned by a protocol server. Indentation and
white space in examples are provided only to illustrate element
relationships and are not a REQUIRED feature of this protocol.
"loginSec-0.3" is used as an abbreviation for
"urn:ietf:params:xml:ns:epp:loginSec-0.3". The XML namespace prefix
"loginSec" is used, but implementations MUST NOT depend on it and
instead employ a proper namespace-aware XML parser and serializer to
interpret and output the XML documents.
2. Migrating to Newer Versions of This Extension
(Note to RFC Editor: remove this section before publication as an
RFC.)
Servers which implement this extension SHOULD provide a way for
clients to progressively update their implementations when a new
version of the extension is deployed.
Servers SHOULD (for a temporary migration period) provide support for
older versions of the extension in parallel to the newest version,
and allow clients to select their preferred version via the
<svcExtension> element of the <login> command.
If a client requests multiple versions of the extension at login,
then, when preparing responses to commands which do not include
extension elements, the server SHOULD only include extension elements
in the namespace of the newest version of the extension requested by
the client.
When preparing responses to commands which do include extension
elements, the server SHOULD only include extension elements for the
extension versions present in the command.

Internet-Draft loginSec January 2019
3. Object Attributes
This extension adds additional elements to [RFC5730] login command
and response. Only those new elements are described here.
3.1. Event
A security event, using the <loginSec:event> element, represents
either a warning or error identified by the server after the client
has connected and submitted the login command. There MAY be multiple
events returned that provides information for the client to address.
The <loginSec:event> MAY include a free form description. All of the
security events use a consistent set of attributes, where the exact
set of applicable attributes is based on the event type. The
supported set of <loginSec:event> element attributes include:
"type": A REQUIRED attribute that defines the type of security
event. The enumerated list of "type" values include:
"password": Identifies a password expiry event, where the
password expires in the future or has expired based on the
"exDate" date and time.
"certificate": Identifies a client certificate expiry event,
where the client certificate will expire at the "exDate" date
and time.
"cipher": Identifies the use of an insecure or deprecated TLS
cipher suite.
"tlsProtocol": Identifies the use of an insecure or deprecated
TLS protocol.
"newPW": The new password does not meet the server password
complexity requirements.
"stat": Provides a login security statistical warning that MUST
set the "name" of the statistic.
"custom": Custom event type that MUST set the "name" attribute
with the custom event type name.
"name": Used to define a sub-type or the type name when the "type"
attribute is "custom".
"level": Defines the level of the event as either "warning" for a
warning event that needs action, or "error" for an error event
that requires immediate action.
"exDate": Contains the date and time that a "warning" level has or
will become an "error" level. At expiry there MAY be an error to
connect or MAY be an error to login. An example is an expired
certificate that will result in a error to connect or an expired
password that may result in a failed login.
Gould & Pozun Expires July 19, 2019 [Page 4]
Internet-Draft loginSec January 2019
"value": Identifies the value that resulted in the login security
event. An example is the negotiated insecure cipher suite or the
negotiated insecure TLS protocol.
"duration": Defines the duration that a statistical event is
associated with.
"lang": Identifies the language of the free form description if the
negotiated language is something other than the default value of
"en" (English).
Example login security event for a password expiring in a week:
<loginSec:event
type="password"
level="warning"
exDate="2018-04-01T22:00:00.0Z"
lang="en">
Password expiration soon
</loginSec:event>
Example login security event for identifying 100 failed logins over
the last day, using the "stat" sub-type of "failedLogins":
<loginSec:event
type="stat"
name="failedLogins"
level="warning"
value="100"
duration="P1D">
Excessive invalid daily logins
</loginSec:event>
3.2. "[LOGIN-SECURITY]" Password
The <loginSec:pw> element MUST override the [RFC5730] <pw> element
only if the <pw> contains the predefined value of "[LOGIN-SECURITY]",
which is a constant value for the server to use the <loginSec:pw>
element for the password. Similarly, the <loginSec:newPW> element
MUST override the [RFC5730] <newPW> element only if the <newPW>
contains the predefined value of "[LOGIN-SECURITY]", which is a
constant value for the server to use the <loginSec:newPW> element for
the new password. The "[LOGIN-SECURITY]" pre-defined string MUST be
supported by the server for the client to explicitly indicate to the
server whether to use <loginSec:pw> element in place of the [RFC5730]
<pw> element or to use the <loginSec:newPW> in place of the [RFC5730]
<newPW> element.
Gould & Pozun Expires July 19, 2019 [Page 5]
Internet-Draft loginSec January 2019
3.3. Dates and Times
Date and time attribute values MUST be represented in Universal
Coordinated Time (UTC) using the Gregorian calendar. The extended
date-time form using upper case "T" and "Z" characters defined in
[W3C.REC-xmlschema-2-20041028] MUST be used to represent date-time
values, as XML Schema does not support truncated date-time forms or
lower case "T" and "Z" characters.
4. EPP Command Mapping
A detailed description of the EPP syntax and semantics can be found
in the EPP core protocol specification [RFC5730].
4.1. EPP <login> Command
This extension defines additional elements to extend the EPP <login>
command and response to be used in conjunction with [RFC5730].
The EPP <login> command is used to establish a session with an EPP
server. This extension overrides the password that is passed with
the [RFC5730] <pw> or the <newPW> element as defined in Section 3.2.
A <loginSec:loginSec> element is sent along with the [RFC5730]
<login> command and MUST contain at least one of the following child
elements:
<loginSec:userAgent>: OPTIONAL client user agent that identifies the
client software and platform used by the server to identify
functional or security constraints, current security issues, and
potential future functional or security issues for the client.
<loginSec:pw>: OPTIONAL plain text password that is case sensitive,
has a minimum length of 6 characters, and has a maximum length
that is up to server policy. All leading and trailing whitespace
is removed, and all internal contiguous whitespace that includes
#x9 (tab), #xA (linefeed), #xD (carriage return), and #x20
(space) is replaced with a single #x20 (space). This element
MUST only be used if the [RFC5730] <pw> element is set to the
"[LOGIN-SECURITY]" value.
<loginSec:newPW>: OPTIONAL plain text new password that is case
sensitive, has a minimum length of 6 characters, and has a
maximum length that is up to server policy. All leading and
trailing whitespace is removed, and all internal contiguous
whitespace that includes #x9 (tab), #xA (linefeed), #xD (carriage
return), and #x20 (space) is replaced with a single #x20 (space).
This element MUST only be used if the [RFC5730] <newPW> element
is set to the "[LOGIN-SECURITY]" value.

Upon a completed login command (success or failed), the extension
MUST be included in the response based on the following conditions:
Client supports extension: client supports the extension based on
the <svcExtension> element of the <login> command.
At least one login security event: The server has identified at
least one login security event to communicate to the client.
The extension to the EPP response uses the <loginSec:loginSecData>
element that contains the following child elements:

One schema is presented here that is the EPP Login Security Extension
schema.
The formal syntax presented here is a complete schema representation
of the object mapping suitable for automated validation of EPP XML
instances. The BEGIN and END tags are not part of the schema; they
are used to note the beginning and ending of the schema for URI
registration purposes.

6. IANA Considerations
6.1. XML Namespace
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688]. The
following URI assignment is requested of IANA:
Registration request for the loginSec namespace:
URI: urn:ietf:params:xml:ns:epp:loginSec-0.3
Registrant Contact: IESG
XML: None. Namespace URIs do not represent an XML specification.
Registration request for the loginSec XML schema:
URI: urn:ietf:params:xml:schema:epp:loginSec-0.3
Registrant Contact: IESG
XML: See the "Formal Syntax" section of this document.

6.2. EPP Extension Registry
The EPP extension described in this document should be registered by
the IANA in the EPP Extension Registry described in [RFC7451]. The
details of the registration are as follows:
Name of Extension: "Login Security Extension for the Extensible
Provisioning Protocol (EPP)"
Document status: Standards Track
Reference: (insert reference to RFC version of this document)
Registrant Name and Email Address: IESG, <iesg@ietf.org>
TLDs: Any
IPR Disclosure: None
Status: Active
Notes: None
7. Implementation Status
Note to RFC Editor: Please remove this section and the reference to
RFC 7942 [RFC7942] before publication.
TBD
8. Security Considerations
The extension leaves the password (<pw> element) and new password
(<newPW> element) minimum length beyond 6 characters and the maximum
length up to sever policy. The server SHOULD enforce minimum and
maximum length requirements that are appropriate for their operating
environment. One example of a guideline for password length policies
can be found in section 5 of NIST Special Publication 800-63B [1].
The client SHOULD NOT decrease the security of a new password by
decreasing the length of the current password. For example, a client
with a 20 character password set using the extension, should not use
the login command in [RFC5730] without using the extension, to set a
new password that is less than or equal to 16 characters.
The extension provides an extensible list of login security events to
inform clients of connection and login warnings and errors.

Appendix A. Change History
A.1. Change from 00 to 01
1. Based on the feedback from Patrick Mevzek and a proposal from
Scott Hollenbeck, changed the minimum length of the password from
8 to 6, revised the description of the password, and added text
in the Security Considerations section for the server password
length policy.
A.2. Change from 01 to 02
1. Changed the XML namespace from urn:ietf:params:xml:ns:loginSec-
0.3 to urn:ietf:params:xml:ns:epp:loginSec-0.3, and changed the
XML schema registration from urn:ietf:params:xml:ns:loginSec-0.3
to urn:ietf:params:xml:schema:epp:loginSec-0.3 based on a request
from IANA with draft-ietf-regext-allocation-token.
A.3. Change from 02 to 03
Updates based on the review by Patrick Mevzek, that include:
1. Fix the inconsistent case for newPW, that required a global
change in the draft text and an update to the XML schema to
"urn:ietf:params:xml:ns:loginSec-0.3".
2. Changed "contains the following child elements" to "MUST contain
at least one of the following child elements", section "EPP
<login> Command" to ensure that an empty <loginSec:loginSec>
element is not passed.
3. Add "The client SHOULD NOT decrease the security of a new
password by decreasing the length of the current password." along
with an example to the "Security Considerations" section.
