Can I ask for some informed opinions, please? The recent furore about potential or actual Mac vulnerabilities is causing me a few minor headaches. I have come to Macs from a Windows background mainly because I was getting fed up with being infected with so many viruses and other mal-wares (the majority being delivered courtesy of the 'totally secure' firewalled academic network on which I was linked - LOL). I have my two Macs (PowerBook G4 and PowerMac G4) configured identically and with fully up-dated Panther 10.3.9 as the OS. On both machines, there is the root administrator account (disabled by default but used regularly for running rkhunter to look for and eliminate any potential rootkits - none found so far), my own administrator account for routine maintenance and installation etc. of apps/utilities and a further 'daily' account that is the one I use routinely for running the apps. and doing my regular work, but where access to the utilities is denied. Both machines are connected to Broadband and I use Airport and a protected wireless router for having the PowerBook communicate with the PowerMac. I have the Mac OSX firewall active, all sharing is turned off and Safari is set to NOT open any downloaded material including pictures. Further, Little Snitch is constantly running in the background and pretty well every request to communicate with any address is denied unless I am certain that I, or the relevant app, am calling for it. As an extra, I am coming to the end of an evaluation period of The Little Dutch Moose that is the first thing to be loaded on start-up; its log suggests that there have been zero attacks or processes that are monitoring my machines. I don't go to any suspect web sites, don't have any software that derives from potentially unreliable suppliers (torrents, hacks, cracks or anywhere from Russia etc) and don't do on-line banking. Am I secure from any external attacks? Am I being over-the-top, even paranoid, in that, despite all the comments from seasoned Mac users, any OS is potentially vulnerable and someone out there could, and probably does, have the ability to do me some damage if I opened my door even an inch? Does anyone else follow my operational route, or am I wasting my time and having unnecessary CPU capacity occupied with trivial activities?
