Your password may not be secure — update it now

The National Institute of Standards and Technology (NIST) once said that a good password consisted of three things: upper- and lowercase letters, numbers, and symbols. However, the NIST has now reversed its stance on good passwords. Here’s why and what they are now recommending.

The problem

The issue isn’t that the NIST advised people to create easy-to-crack passwords, but their previous advice inadvertently made people generate weak passwords using predictable capitalization, special characters, and numbers, like “P@ssW0rd1.”

Such a password may seem secure, but the string of characters it’s made up of could easily be compromised by hackers using common algorithms.

Furthermore, while the NIST also recommended that people change their passwords regularly, they did not specify how and when to change them. Without proper guidance, many people assumed that this meant adding or changing one or two characters every year or so.
The NIST essentially forced everyone to use passwords that are hard for humans to remember but easy for a hacker’s algorithm to crack.

Eventually, the institution admitted that their recommendation creates more problems than it solves. The NIST has then reversed its stance on organizational password management requirements, and is recommending banishing forced periodic password changes and getting rid of complexity requirements.

The solution

Security consultant Frank Abagnale and Chief Hacking Officer for KnowBe4 Kevin Mitnick both see a future without passwords. Both security experts advise enterprises to implement multifactor authentication (MFA) in login policies.

MFA requires a user to enter one or more valid credentials aside from a password to gain access to an account. This could be a physical security key, a login prompt on a mobile device, or a facial or a fingerprint scan. Without the additional security requirements, hackers’ attempts to crack passwords would be futile.

Moreover, Mitnick recommended implementing long passphrases of 25 characters or more, such as “recedemarmaladecrockplacate” or “cavalryfigurineunderdoneexalted.” These are much more difficult to guess and less prone to hacking. Simply put, passwords should be longer and include nonsensical phrases and words that make them almost impossible for an automated system to crack.

What’s more, the NIST recommends making screening of new passwords against lists of common or compromised passwords mandatory. This is because a complex, 25-character password is already considered weak the moment it has been compromised.

Finally, you should also enforce the following security solutions within your company:

  • Single sign-on – allows users to securely access multiple accounts with one set of credentials
  • Account monitoring tools – recognizes suspicious activity and locks out hackers from the network OR keeps hackers from accessing the network.

When it comes to security, ignorance is your business’s kryptonite. If you’d like to learn about what else you can do to remain secure, just give us a call.

Very knowledgeable and professional staff that responded quickly, understood what I needed and resolved the issue economically. I had a very specific technical issue with an integration. Although AJ did not have specific knowledge of this very esoteric software, he managed to figure it out within minutes as we were discussing the problem. Very impressed. Thanks Swift Chip.
