De helft van de internetgebruikers maakt verbinding met onveilig netwerk. Zomaar een berichtje over de gevaren van openbare, niet met een wachtwoord beschermde, WiFi netwerken. Allemaal leuk en aardig, maar al die berichten suggereren dat WiFi netwerken met een wachtwoord, of bekabelde netwerken, wel veilig zouden zijn. Niet is minder waar. Alle internetverbindingen zijn onveilig!

A big ransomware campaign is raging on the Internet. Updating your computer regularly, and blocking unneeded ports, are a good first line of defence. Backups are an essential second line of defence.

The person who asked me was busy with a project in a neighbourhood close to where I grew up. Part of it is a national monument. The neighbourhood association wanted to revive the history of the neighbourhood by creating a web page for every house in the neighbourhood. To also restore some of the community spirit they didn’t want to just set up a universally accessible website.
