It goes without saying that the majority of these are either the factory default settings, or painfully unimaginative. SplashData provided some tips for choosing passwords that are more likely to survive a brute-force password hack:
  • Vary different types of characters in your passwords; include numbers, letters and special characters when possible.
  • Choose passwords of eight characters or more. Separate short words with spaces or underscores.
  • Don’t use the same password and username combination for multiple websites. Use an online password manager to keep track of your different accounts.

Integrated Automation adds the following advice:

  • Ensure that passwords for control systems are unique for each individual, logout after a period of inactivity, and are changed periodically. We note however that it isn't always practical for a shared SCADA terminal for example to comply fully.
  • Ensure that automation networks are protected by firewalls to control traffic across all network segment interfaces.
  • Ensure that wireless systems use encryption, and try to contain spill beyond the premises by reducing signal strength, or using sectoral / directional antennas rather than omni-directional.
