    Are you concerned about sensitive data leaving the PC or some sort of infection (like a crypto-locker) being brought onto it? Also, what is your threat level? Are you likely to be targeted specifically?

    With an airgap, it would be pretty difficult to get data off of it without being onsite. The most important things would be physically securing the device (locked room), using full disk encryption, and using some sort of 2-factor login system. (hardware security key, like a yubikey ideally).

    Securing against infection is nearly impossible, as stuxnet showed. Your best bet to beat these is some common sense security with what you’re transferring and lots of backups. If you do find an infection, you just blow the whole system up and restore from a clean backup.








  • I believe the effect is entirely topical, it just doesn’t hurt to ingest a little too. The fluoride ions trigger re-hardening of the tooth enamel and can take the place of missing calcium in the outer enamel structure, but those only happen when they hit the outer enamel in your mouth, you don’t regrow enamel on fully formed teeth
