Task 5: Configuring security
Perform this task to configure the PMP 450 system in accordance with the network operator‘s security policy.
Choose from the following procedures:
Isolating APs from the internet
: to ensure that APs are properly secured from external
networks
Encrypting radio transmissions
on page
: to configure the unit to operate with AES or DES wireless
link security
Managing module access by passwords
: to set up the AP to require SMs to authenticate via
the AP, Prizm, or RADIUS server
on page
: to filter (block) specified protocols and ports from leaving the
system
Requiring SM Authentication on page
: to configure the network to only allow registration to
authenticated SMs
Encrypting downlink broadcasts on page
: to encrypt downlink broadcast transmissions such as ARP
and NetBIOS
Isolating SMs on page
: to prevent SMs in the same sector from directly communicating with each
other
Filtering management through Ethernet on page
: to prevent management access to the SM via the
radio‘s Ethernet port
Allowing management only from specified IP addresses on page
: to only allow radio management
interface access from specified IP addresses
Configuring management IP by DHCP on page
: to allow the radio‘s management IP address to be
assigned by a network DHCP server
Isolating APs from the internet
Ensure that the IP addresses of the APs in your network
are not routable over the Internet.
do not share the subnet of the IP address of your user.
RFC 1918, Address Allocation for Private Subnets, reserves for private IP networks three blocks of IP
addresses that are not routable over the Internet:
/8 subnets have one reserved network, 10.0.0.0 to 10.255.255.255.
/16 subnets have 16 reserved networks, 172.16.0.0 to 172.31.255.255.
/24 subnets have 256 reserved networks, 192.168.0.0 to 192.168.255.255.
