Passwords and Policies
by Andrew McCaskey
Worth Noting, Again: Password Strength and Security May Not be Related
Always worthwhile to question how much security is really added by password rules and policies. The latest paper by Bruce Schneier notes once again that strong password policies tend to add little to the security posture, especially in the face of keyloggers and phishing attacks that exploit weaknesses in physical access or social engineering.
The combination of more complex user ID’s and shorter passwords (with a three tries rule) seems to offer more protection than enforcing use of more robust passwords. The most destructive combination of all seems to be forced password rotation every few weeks.encouraging trivial passwords with minor rotations ot tweaks. That’s because they are easiest to remember. Human behavior is so messy, yet predictable.
