74 MDS iNET 900 Series User’s Guide MDS 05-2806A01, Rev. E.1
• Encryption— Enable encryption of over-the-air data packets.
[
Enabled, Disabled; Disabled]
Enabling forces the transceiver to use 128-bit encryption on all
over-the-air messages. This option requires the Encryption
Phrase to be previously configured.
•
Auto Key Rotation—Enable automatic rotation of encryption
keys. [
Enabled, Disabled; Disabled]
Enabling forces the transceiver to use the key rotation algorithm
to generate a new encryption key after 500 kilobytes of informa-
tion has been transmitted, or one hour has elapsed. Key rotation
prevents reusing encryption data that could result in key-crack-
ing, unlike standard 802.11b communications that rely on static
encryption keys.
•
HTTP Access—Prevents remote access through HTTP (Web
browser) on Port 80 [
Enabled/Disabled; Disabled]
• SNMP Access— Prevents remote access through SNMP com-
mands on Port 161 [
Enabled, Disabled; Enabled]
• Telnet Access—Prevents remote access through Telnet sessions
on Port 23 [
Enabled, Disabled; Enabled]
• Approved Access Points/Remotes List (Menu)—Go to menu pro-
viding the creation and management list of units permitted (pro-
visioned) with which this unit will be permitted to
communicate.
•
Encryption Phrase—Phrase (text & numbers) that will be part of
the encryption algorithm.
[
Up to 29 alphanumeric characters; Blank]
• Force Key Rotation— It triggers an immediate key rotation of the
encryption keys before the internal counters do it automatically.
•
HTTP Security Mode—Select security mode/level of login via
HTTP browser.
HTTP Access disabled prevents access through
HTTP.
HTTP Security Mode is functional if HTTP Access is
enabled. [
Basic Auth, MD5 Digest; Basic Auth]
Basic mode requires a password, but the actual password text is
transmitted in the clear (unencrypted).
•
User Password—General administrative password only for this
unit. Used at log-in via COM1 Port, Telnet and Web browser.
[
Up to 8-character alphanumeric string without spaces (case-sensitive);
admin
]
TIP: For enhanced security, consider using misspelled words, a combi-
nation of letters and numbers, and a combination of upper and
lower case letters. Also, the password should use all eight charac-
ters. This helps protect against sophisticated hackers who may use
a database of common words (for example, dictionary attacks) to
determine a password.
