301-0399-3 Rev A. - Page 13

3. Operations
Setting the HTTP authentication method:
The AmpMeter PDU HTTP server supports two authentication methods for security and validation of the
username-password – Basic and MD5 digest.
The Basic method utilizes Base64 encoding to encode and deliver the username-password over the network to
the HTTP server for decoding and authentication. This basic method is supported by all web browsers and
offers a minimum level of security.
NOTE: The Base64 algorithm is widely-known and susceptible to packet-sniffer attack for acquisition of the
encoded username-password string.
The MD5 digest method provides stronger protection utilizing one-way encoded hash numbers, never placing
the username-password on the network. Instead, the sending browser creates a challenge code based on the
hash algorithm, provided username-password and unique items such as the device IP address and timestamp,
which is compared against the HTTP server internal user database of valid challenge codes. The MD5 digest
method offers a higher level of security than the Basic method but at present is not supported by all browsers.
NOTE: MD5 is known to be fully supported by Internet Explorer 5.0+, Navigator 7.0+ and Firefox 1.0+.
Select Basic or MD5 from the Authentication drop-down menu and press Apply.
Setting SSL access level
AmpMeter PDU SSL supports configuration of SSL connections as being either optional or required. The
