certnz is our governmental agency charged with setting up a Computer Emergency Response Team (set up in 2016). It is a key part of NZ's cyber security strategy.
This month they are promoting a campaign targeted at making us more aware of the importance of keeping our online transactions safe. We all use multiple websites and apps and have a range of passwords that we hope will keep us secure, but in reality may well be quite insecure for a number of reasons. They may be short passwords or ones we have reused on many sites or ones that are reasonable easy to guess. And of course there continue to be leaks of details online which may see some details shared. certnz is promoting a campaign called "Password Perfect" and basing the campaign on using "passphrases" rather than passwords. The reason for this is reasonably simple - the longer a password is the longer it should take for any attack to crack the password. It is possible to have a password that could take longer then the life of the planet to crack yet remain easy for you to remember ... It is worth paying some attention to keeping your many online accounts safe. Passphrases are worth considering, and it is also worth reading the more detailed version on their website here www.cert.govt.nz/password-perfect/.
