Level 1
Level 1 provides protection against
unauthorized network access. It does not
provide any protection against eavesdropping.
The use of Level 1 is described in NID naming
and security on page 97. Basically, the access
point only allows access to wireless clients with
specific MAC addresses.
This protects you from other normal wireless
LAN users, who might (inadvertently or
otherwise) attempt to join your wireless LAN,
but not against a determined masquerade
attack (where a hacker illegally discovers and
uses your MAC address).
Levels 2 and 3
Levels 2 and 3 use WEP (wire equivalent
privacy). WEP is designed to provide both
access control and eavesdropping protection.
WEP depends on the use of keys (equivalent to
passwords). Both the access point and the
wireless client must know the key. The success
of WEP depends on keeping the key away from
unauthorized persons.
The WEP encryption method is defined by
IEEE802.11. This means that you can use the
Nokia A032 in conjunction with other vendors’
wireless LAN clients that adhere to the
standard.
