Bob Metcalfe talking about ARPANET’s security in 1973 — could have been written today:

“Individual sites, used to physical limitations on machine access, have not yet taken sufficient precautions toward securing their systems against unauthorized remote use. For example, many people still use passwords which are easy to guess: their first names, their initials, their host name spelled backwards, a string of characters which are easy to type in sequence (e.g. ZXCVBNM)...We suspect that the number of dangerous security violations is larger than any of us know is growing. You are advised not to sit ‘in hope that Saint Nicholas would soon be there’.”
