In 2003, a manager at the National Institute of Standards and Technology (NIST) authored a document on password best practices for businesses, federal agencies, and academic institutions. Now retired, the author admits that his document was misguided. Find out why and what great passwords are made of.
The issue isn’t necessarily that NIST advised people to create passwords that are easy to crack, but it did steer people into creating lazy passwords, using capitalisation, special characters, and numbers that are easy to predict, like “[email protected]”
This may seem secure, but in reality, these strings of characters and numbers could easily be compromised by hackers using common algorithms.
To make matters worse, NIST also recommended that people change their passwords regularly, but did not define what it actually means to “change” them. Since people thought their passwords were already secure with special characters, most only added one number or symbol.
NIST essentially forced everyone, including you and your colleagues, to use passwords that are hard for humans to remember but easy for computers to guess.
One cartoonist pointed out just how ridiculous NIST’s best practices were when he revealed that a password like “Tr0ub4dor&3” could be cracked in only three days while a password like “correcthorsebatterystaple” would take about 550 years.
Simply put, passwords should be longer and include nonsensical phrases and English words that make it almost impossible for an automated system to make sense of.
Even better, you should enforce the following security solutions within your company:
- Multi-factor Authentication – which only grants access after you have successfully presented several pieces of evidence
- Single Sign-On – which allows users to securely access multiple accounts with one set of credentials
- Account Monitoring Tools – which recognize suspicious activity and lock out hackers
When it comes to security, ignorance is the biggest threat. If you’d like to learn about what else you can do to fortify security, just give Multi IT a call on 011 435 0450.
