1. Introduction
This document describes an extension mapping for version 1.0 of the
Extensible Provisioning Protocol (EPP) [RFC5730]. This document
describes an extension of the Registry Mapping
[I-D.gould-carney-regext-registry] to define the server policy of the
Gould Expires February 3, 2020 [Page 2]
Internet-Draft loginsec-policy August 2019
Login Security EPP extension [I-D.gould-regext-login-security] for a
registry system.
1.1. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
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.
The XML namespace prefix "loginSecPolicy" is used for the namespace
"urn:ietf:params:xml:ns:epp:loginSecPolicy-0.4", 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.
The XML namespace prefix "loginSec" is used for the namespace
"urn:ietf:params:xml:ns:loginSec-0.1", as defined in
[I-D.gould-regext-login-security], 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. Object Attributes
An EPP login security policy has attributes and associated values
that may be viewed and modified by the sponsoring client or the
server. This section describes each attribute type in detail. The
formal syntax for the attribute values described here can be found in
the "Formal Syntax" section of this document and in the appropriate
normative references.
2.1. 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 XML
Schema Part 2 [1] MUST be used to represent date-time values, as XML
Gould Expires February 3, 2020 [Page 3]
Internet-Draft loginsec-policy August 2019
Schema does not support truncated date-time forms or lower case "T"
and "Z" characters.
2.2. Event Types
The <loginSecPolicy:event> element has a REQUIRED "type" attribute
and an OPTIONAL "name" attribute that defines the security event
type. The "name" attribute is used to define a sub-type or the type
name when the "type" attribute is "custom". The enumerated list of
"type" values include:
"password": Identifies a password expiry event policy.
"certificate": Identifies a client certificate expiry event policy.
"cipher": Identifies an insecure or deprecated TLS cipher suite
event policy.
"tlsProtocol": Identifies an insecure or deprecated TLS protocol
event policy.
"newPW": Identifies the new password complexity requirements event
policy.
"stat": Identifies the login security statistical warning event
policy. The "name" attribute defines the statistic.
"custom": Identifies a custom event type that MUST set the "name"
attribute with the custom event type name.
2.3. System Object
The System object, represented by the <registry:system> element in
the Registry Mapping [I-D.gould-carney-regext-registry], is the
object that is extended by this extension with the
<loginSecPolicy:system> element. The <loginSecPolicy:system> element
contains the following child elements:
<loginSecPolicy:pw>: The login password format policy. The
<loginSecPolicy:pw> element contains the following child
elements:
<loginSecPolicy:expression>: The login password format
regular expression. The regular expression MUST conform
to the Perl-compatible Regular Expression (PCRE) [pcre]
syntax. Programming languages support different sets of
PCRE features, so the server SHOULD define a PCRE that
leverages features that are supported by a broad set of
client programming languages.
<loginSecPolicy:description>: The OPTIONAL human readable
description of the login password format policy. The
Gould Expires February 3, 2020 [Page 4]
Internet-Draft loginsec-policy August 2019
"lang" attribute MAY be present to identify the language
of the description if the negotiated value is something
other than the default value of "en" (English).
<loginSecPolicy:specialRules>: The OPTIONAL boolean element,
with a default value of "false", that indicates additional
special format rules apply that cannot be represented in
the regular expression. A value of "1" (or "true") means
that special format rules do apply that MUST be described
in the <loginSecPolicy:description> element for manual
review. The server SHOULD represent the most specific
regular expression possible with the
<loginSecPolicy:expression> element. A value of "0" (or
"false") means that the <loginSecPolicy:expression>
element fully represents the format requirements.
<loginSecPolicy:restrictedWords>: The OPTIONAL boolean
element, with a default value of "false", that indicates
that the server has a list of restricted words that cannot
be used in the password. The optional "url" attribute
references a description of the list of restricted words.
<loginSecPolicy:userAgentSupport>: OPTIONAL boolean value that
indicates the server supports the <loginSec:userAgent>
element, with the default value of "0" (or "false"). A value
of "1" (or "true") means that the server processes the
<loginSec:userAgent> element. A value of "0" (or "false")
means that the server ignores the <loginSec:userAgent> element
if passed by the client.
<loginSecPolicy:event>: Zero or more <loginSecPolicy:event>
elements that defines the policies associated with the
supported security events. The required "type" attribute and
the OPTIONAL "name" attribute defines the event type, as
described in Section 2.2. The <loginSecPolicy:event> element
contains the following child elements:
<loginSecPolicy:level>: One or two <loginSecPolicy:level>
elements that indicate the possible set of event levels
("warning" or "error") the server will return to the
client for the event type.
<loginSecPolicy:exDate>: OPTIONAL boolean element that
indicates whether the event type includes a
<loginSec:exDate> element with the default value of "0"
(or "false").
<loginSecPolicy:exPeriod>: OPTIONAL duration element that the
event type must be reset. For example, the password will
expire 30 days after being set.
<loginSecPolicy:warningPeriod>: OPTIONAL duration element
that indicates how long prior to expiry the server will
include a warning event. For example, the server will
Gould Expires February 3, 2020 [Page 5]
Internet-Draft loginsec-policy August 2019
include a password expiry warning event 15 days prior to
expiry.
<loginSecPolicy:errorAction>: OPTIONAL indication of what
action will occur with an error, including at expiry when
<leoginSecPolicy:exDate> is "1" (or "true"). The possible
<loginSecPolicy:errorAction> values include:
"connect": The client connection will fail. For example,
when the client certificate expires, the TLS handshake
will fail.
"login": The client login will fail. For example, when
the new password does not meet the server password
complexity requirements or when the password expires,
the login will fail.
"none": There is no predefined failure action. For
example, when the password expires, the server will
not fail the login.
<loginSecPolicy:threshold>: OPTIONAL threshold value that
triggers a warning event for a specific "stat" event. For
example, a "failedLogins" "stat" warning event will occur
if the number of failed logins exceeds 100.
<loginSecPolicy:period>: OPTIONAL period value that is
associated with a warning event for a specific "stat"
event. For example, a "failedLogins" "stat" warning event
will occur if the number of failed logins exceeds the
<loginSecPolicy:threshold> value over a period of 1 day.
Example of a <loginSecPolicy:system> element that defines the
password policy and the policy of each of the supported login
security events:
<loginSecPolicy:system>
<loginSecPolicy:pw>
<loginSecPolicy:expression>
(?=.*\d)
(?=.*[a-zA-Z])
(?=.*[\x21-\x2F\x3A-\x40\x5B-\x60\x7B-\x7E])
(?!^\s+)
(?!.*\s+$)
(?!.*\s{2,})
^[\x20-\x7e]{16,32}$
</loginSecPolicy:expression>
<loginSecPolicy:description>
16 to 32 printable characters (alphanumeric, space, and
special characters) with at least one number, letter, and
special character, with no leading or trailing whitespace,
and with no consecutive spaces.

3. EPP Command Mapping
A detailed description of the EPP syntax and semantics can be found
in the EPP core protocol specification [RFC5730]. The command
mappings described here are specifically for use in provisioning and
managing login security policy via EPP.
3.1. EPP Query Commands
EPP [RFC5730] provides three commands to retrieve object information:
<check> to determine if an object is known to the server, <info> to
retrieve detailed information associated with an object, and
<transfer> to retrieve object transfer status information.
3.1.1. EPP <check> Command
This extension does not define any extension of the EPP <check>
command or response described in the Registry Mapping.
3.1.2. EPP <info> Command
This extension does not add any elements to the EPP <info> command
described in the Registry Mapping [I-D.gould-carney-regext-registry].
Gould Expires February 3, 2020 [Page 8]
Internet-Draft loginsec-policy August 2019
However, additional elements are defined for the <info> response to a
query for the registry system attributes.
When an <info> command has been processed successfully, the EPP
<resData> element MUST contain a child elements as described in the
Registry Mapping [I-D.gould-carney-regext-registry]. In addition,
the EPP <extension> element SHOULD contain a child <lp:infData>
element that identifies the extension namespace if the system object
has data associated with this extension and based on server policy.
The <loginSecPolicy:infData> element contains the following child
elements:
<lp:system>: Element that contains the full set of login security
policy attributes for the system as defined in Section 2.3.
Example <info> response to query for the registry system attributes
including the login security policy attributes:
S:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
S: <response>
S: <result code="1000">
S: <msg>Command completed successfully</msg>
S: </result>
S: <resData>
S: <registry:infData
S: xmlns:registry="urn:ietf:params:xml:ns:registry-0.1">
S: ...
S: </registry:infData>
S: </resData>
S: <extension>
S: <loginSecPolicy:infData
S: xmlns:loginSecPolicy=
S: "urn:ietf:params:xml:ns:epp:loginSecPolicy-0.4">
S: ...
S: </loginSecPolicy:infData>
S: </extension>
S: <trID>
S: <clTRID>ABC-12345</clTRID>
S: <svTRID>54322-XYZ</svTRID>
S: </trID>
S: </response>
S:</epp>
Gould Expires February 3, 2020 [Page 9]
Internet-Draft loginsec-policy August 2019
3.1.3. EPP <transfer> Query Command
Transfer semantics do not directly apply to system objects, so there
is no extension defined for the EPP <transfer> query command.
3.2. EPP Transform Commands
EPP provides five commands to transform objects: <create> to create
an instance of an object, <delete> to delete an instance of an
object, <renew> to extend the validity period of an object,
<transfer> to manage object sponsorship changes, and <update> to
change information associated with an object.
3.2.1. EPP <create> Command
This extension does not add any elements to the EPP <create> command
or <create> response described in the Registry Mapping.
3.2.2. EPP <delete> Command
This extension does not add any elements to the EPP <delete> command
or <delete> response described in the Registry Mapping.
3.2.3. EPP <renew> Command
Renew semantics do not directly apply to system objects, so there is
no extension defined for the EPP <renew> command.
3.2.4. EPP <transfer> Command
Transfer semantics do not directly apply to system objects, so there
is no extension defined for the EPP <transfer> command.
3.2.5. EPP <update> Command
This extension does not add any elements to the EPP <update> command
or <update> response described in the Registry Mapping.
4. Formal Syntax
One schema presented here is the EPP Login Security Policy 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.

5. IANA Considerations
5.1. XML Namespace
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688].
Registration request for the login security policy namespace:
Gould Expires February 3, 2020 [Page 13]
Internet-Draft loginsec-policy August 2019
URI: urn:ietf:params:xml:ns:epp:loginSecPolicy-0.4
Registrant Contact: IESG
XML: None. Namespace URIs do not represent an XML specification.
Registration request for the login security policy XML schema:
URI: urn:ietf:params:xml:schema:epp:loginSecPolicy-0.4
Registrant Contact: IESG
XML: See the "Formal Syntax" section of this document.
5.2. 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 Policy Extensions Mapping 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
6. Implementation Status
Note to RFC Editor: Please remove this section and the reference to
RFC 7942 [RFC7942] before publication.
This section records the status of known implementations of the
protocol defined by this specification at the time of posting of this
Internet-Draft, and is based on a proposal described in RFC 7942
[RFC7942]. The description of implementations in this section is
intended to assist the IETF in its decision processes in progressing
drafts to RFCs. Please note that the listing of any individual
implementation here does not imply endorsement by the IETF.
Furthermore, no effort has been spent to verify the information
presented here that was supplied by IETF contributors. This is not
intended as, and must not be construed to be, a catalog of available
Gould Expires February 3, 2020 [Page 14]
Internet-Draft loginsec-policy August 2019
implementations or their features. Readers are advised to note that
other implementations may exist.
According to RFC 7942 [RFC7942], "this will allow reviewers and
working groups to assign due consideration to documents that have the
benefit of running code, which may serve as evidence of valuable
experimentation and feedback that have made the implemented protocols
more mature. It is up to the individual working groups to use this
information as they see fit".
6.1. Verisign EPP SDK
Organization: Verisign Inc.

The mapping extensions described in this document provide additional
security services beyond those described by EPP [RFC5730] and
protocol layers used by EPP. The security considerations described
in these other specifications apply to this specification as well.
This mapping does define the login security policy of the server,
where there are security considerations with defining the policy,
which include:
1. The server SHOULD follow login password complexity best
practices, such as the NIST Special Publication 800-63B [2].
2. The server MAY have a login password expiry that requires the
client to regularly change the login password.
3. The server SHOULD inform the client of the expiry of the login
password.

4. The server MUST store the login password at rest securely, such
as hashing or encrypting the login password.
5. The server SHOULD deprecate and eliminate insecure ciphers and
protocols.
6. The server SHOULD inform the client of the use of insecure
ciphers and protocols.
7. The server SHOULD inform the client of an expiring client
certificate.

Appendix A. Change History
A.1. Change from 00 to 01
1. Changed the <loginSecPolicy:exError> element to the
<loginSecPolicy:errorAction> element, to be more generic to
identify the action taken for an error level event for any event
type. The XML namespace was changed to
"urn:ietf:params:xml:ns:epp:loginSecPolicy-0.3" based on the
change to the XML schema.
2. Updated the Implementation Status section.
A.2. Change from 01 to 02
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:epp:loginSecPolicy-0.3".
A.3. Change from 02 to 03
1. Added support for the <loginSecPolicy:specialRules> and
<loginSecPolicy:restrictedWords> elements in the
<loginSecPolicy:pw> element to support cases where the server has
special format rules or restricts certain words for the password.
Adding the new elements resulted in updating the XML schema to
"urn:ietf:params:xml:ns:epp:loginSecPolicy-0.4".
