How to Survive?

Attending a conference with a public network is not without security risks. You are often directly connected to the Internet. Consider it the Wild Wild West. Before coming to the event, please be sure to follow the following best practices:

• General rules
  • If possible bring a dedicated device to the conference with a fresh & limited set of softwares and data. Don't take a brand new one, it can be hit by flying objects, fall or flooded by beer.
  • Don't bring confidential data with you.
  • Do not carry business documents and keep your USB sticks away from other participants.
  • If you bring your regular device, perform a full backup of your data and restore them after the conference
  • Be sure to use fully-patched softwares
  • Take care of physical security: put BIOS passwords, don't leave your devices unattended.
  • Put labels on your hardware (if you'd like to remain anonymous, don't put your name but a unique detail like a sticker under the battery to make the device easily identifiable)
  • Encrypt everything, always
    • Encrypt your disks (TruCrypt)
    • If you need to communicate over the wild Internet, use VPN or any other kind of tunneling like SSH tunnels.
    • Avoid any unsecured protocols like POP3, IMAP, HTTP-auth, Instant Messenger, Twitter (cookies)
  • Do not trust anybody! Even not secured web-sites.
  • Don't log with administrative rights (Administrator, root, ...)
  • Lock your sessions if you stand-by your device
  • Be prepared to the worst case, shit appens!

• Platform Specific rules
  • Microsoft OS
    • Be sure to have an anti-virus running (with up-to-date signatures) and a firewall.
    • Disable all unwanted services (Go to 'Start', 'System Settings', 'Services', 'Properties of service' then 'Stop').
  • MacOS
    • Disable all unwanted services (Go to 'System Preferences', 'Sharing', 'Services' and uncheck all the things you don't need).
    • Protect your Keychain access (where all your password are stored). Start the Keychain utility (Go to 'Applications', 'Utilities' then 'Keychain Access'). Select the 'login' keychain from the sidebar and go to the menu 'Edit', 'Change Settings' for Keychain "login"'.
