My main concern is Internet Banking. The banks have protected themselves but have left a black hole where customer security should be in order to limit their liability. In the event of a loss of any size they can then point to a lack of security by the customer. This is a difficult area and many people have differing views on what is the right way to lock down a system. Currently I have a desktop and a laptop, single port Alcatel Speed Touch ADSL modem and Zone Alarm Pro, WinASO,Spybot, SpywareBlaster, SpywareGuard. I intend establishing..... Home network behind a Linksys WAG54G Wireless Router ADSL 2/2+Modem. (Overkill on the modem but I want ADSL2+ when available) With Zone Alarm Pro this gives me hardware and software modems. The laptop has sensitive information...banking, private correspondence, legal papers etc. The two desktops have the remaining programs and files. My intention is to do my periodic Internet Banking and then physically disconnect the laptop from the network until the next session. Maybe that is unnecessary but it does slam the door and the online exposure is minimal. The only problem I see here is incorrect settings in either firewall.....and I am not underestimating that Black Science. I am hoping that this will render most of the Security program add-ons ...Port Explorer, WinPatrol, TrojanGuard et al largely unnecessary. Speaking off the top of my head here because my understanding is minimal, I would like to close all ports on the laptop except that required for banking access. Is that possible and how would I determine that? Could some member point me to a good source for understanding ports? This is a very rough draft of my take on the possibilities and any input would be welcome.
