Instructions for secure network design

Note the information below to protect your network against attacks:
● Use a secure connection with HTTPS
In contrast to HTTP, HTTPS allows you secure access for configuring the WLAN clients and
the access points using Web Based Management. For more detailed information, refer to
the section "Load & Save (Page 152)".
● Use WPA2/ WPA2-PSK with AES
Use only WPA2/AES to prevent password misuse. WPA2/ WPA2-PSK with AES provides
the greatest security. For more detailed information, refer to the section ""Security" menu
(Page 293)".
● Protect your network from man-in-the-middle attacks
To protect your network from man-in-the-middle attacks, a network setup is recommended
that makes it more difficult for the attacker to access the communications path between two
end devices.
– You can, for example, protect devices by arranging so that the Agent IP is only
– A further option is to install a separate HTTPS certificate on the WLAN client / access
● Use SNMPv3
SNMPv3 provides you with highest possible security when accessing the devices via
SNMP. For more detailed information, refer to the section "SNMP (Page 181)".
