Re: not just banks
Its difficult to resist as we're a curious lot in IT. Nowhere near a bank but in a lodge on IOW, I've snooped round in the loft and found their, quite decent switch that they use for each lodge. Good job I did as one of the bedroom TVs wasn't working. And turned out to be a loose cable in the switch, wasn't clicked into place. They correctly disabled all ports on the switch that weren't in use and the WiFi for each lodge had isolation on. The only shit part was their bullshit advertising of fast internet. It was far from it, it was worse than dialup.
Another site, the whole park was wide open. From the lodge you could get to the main router that control all the other 6 or 7 lodges. The password was left as the default. You could even connect to the printer in their office. Was at Christmas. I was very tempted to send a print but didn't.
Another place with a few lodges spaced a good distance apart also had issues. But the couple that run it are nice so I reported the issues via email. And gave them free IT advice or what to do to fix the issues (I guess thats why I have no money, giving advice for free instead of becoming a bullshitting consultant)
