WCC3.EXE SCREEN DESCRIPTIONS
The User Name can be up to 30 characters (control codes, ALT
codes, and the double quote character are not allowed). The
password can be up to 20 characters (control codes, ALT codes,
and the double quote character are not allowed). The User Name
and Password are the ones set up for the Backtask program’s e-mail
account. Both the user name and password are case-sensitive.
Authentication:
For e-mail servers that require authentication, this fi eld should
be set to Auto, Login or Plain. For e-mail servers that do not
require authentication, this fi eld should be set to “No.” - See
your Internet provider and/or IT personnel for this setting.
E-mail authentication from the WCC3 system is the effort to
equip E-mail messages of the WCC3 e-mail transport system
with enough verifi able information, so that the End User
recipient’s E-mail server can recognize the nature of each
incoming message from the WCC III - MCD email’s SMTP
automatically without rejecting it as SPAM. WattMaster
Controls, Inc. supports 4 basic types of E-mail authentication—
AUTO, PLAIN, LOGIN, and CRAM-MD5.
AUTO :
In the WCC3 system, the selection for authentication
“AUTO” applies to The Password Authentication Protocol
(capitalized) and is sometimes abbreviated PAP. PAP is a simple
password authentication protocol that is used to authenticate a user
to a network access server used for example by internet service
providers. PAP is used by Point to Point Protocol to validate users
before allowing them access to server resources. Almost all network
operating system remote E-mail servers support PAP. It requires
that you have both a legitimate “User Name” and “Password”.
PLAIN: In the WCC3 system, the selection for authentication
“PLAIN” applies to unencrypted “Plain” text that is sent to and
from the E-mail SMTP server. It is most commonly associated
with a POP3 type E-mail server.
The Post Offi ce Protocol (POP) is an application-layer Internet
standard protocol used by E-mail user accounts to send and
retrieve e-mail from a remote server over a TCP/IP connection.
POP and IMAP (Internet Message Access Protocol) are the two
most prevalent Internet standard protocols for e-mail retrieval.
Virtually all modern e-mail clients and servers support both. The
POP protocol has been developed through several versions with
version 3 (POP3) being the current standard.
LOGIN: Login Authentication is a process closely related to
identifi cation. In online E-mail environments where “login”
authentication is required, the username identifi es the user, while
the password authenticates that the user is whom he or she claims
to be. Typically, the “Login” authentication is used on E-mail
servers with SSL type E-mail protocols.
Secure Sockets Layer (SSL), are cryptographic protocols that
provide a level of security for secure communications over
networks such as the Internet.
CRAM-MD: In CRAM-MD5 authentication, the server fi rst
sends a challenge string to the client. The client responds with a
username followed by a space character and then a 16-byte digest
in hexadecimal notation. The digest is the output of HMAC-MD5
with the user’s password as the secret key and the server’s original
challenge as the message. The server also calculates its own digest
with its notion of the user’s password, and if the client’s digest and
the server’s digest match then authentication is successful.
This provides three important types of security. First, others cannot
duplicate the hash without knowing the password. This provides
authentication. Second, others cannot replay the hash—it is
dependent on the unpredictable challenge. This is variously called
freshness or replay prevention. Third, observers do not learn the
password. This is called secrecy. The two important features of this
protocol that provide these three security benefi ts are the one-way
hash and the fresh random challenge.
System ID:
The system ID fi eld on the WCC3 System Parameters Screen
is used to identify the actual physical location of the WCC3
system. This System ID “Name” will be on all of the E-mails
that this specifi c WCC III - MCD will send out, in the center of
the Main Screen of the WCC3.exe program, and on the Energy
Consumption Table. This fi eld on the WCC3 System Parameters
Screen is limited to 50 total characters (control codes, ALT codes,
and the double quote character are not allowed) for the System
