Don't confuse wireless LAN security issues with wireless broadband security issues. The former are often discussed - e.g. ways to secure your wireless LAN router etc. The latter not so much but unlike wireless LANs (usually 802.11b/g operating in the 2.4GHz band) most people don't have the necessary equipment to eavesdrop and hack wireless broadband signals (usually WiMax or some variant on that theme operating at a different frequency to 802.11a (5GHz) or 802.11b/g (2.4GHz)). If you have a wireless LAN router then make sure that this is secured. Otherwise you can probably consider your wirelss broadband connection back to the IBB site as secure for all intents and purposes. However, as ever only used secure (HTTPS/SSL) sites for very sensitive stuff like online banking/purchases etc.). Hope that helps?
