Passwords May Never Die for Legal Reasons

"Passwords are dead," a Google information security manager decreed at last month's TechCrunch Disrupt. Other pundits have come to the same conclusion. However, these reports are greatly exaggerated.

Admittedly, passwords can be problematic, as this message board comment from E2 Editor-in-Chief Sara Peters illustrates:

You can set up the system so that users must use a password that's more than 8 characters long and has a mixture of uppercase letters, lowercase letters, numbers, and special characters; and that it be changed every three months, and when you change it, it can't be the same as any password you've had previously. That's not hard.

Not hard? Really? Because just thinking about that makes me want to shoryuken the nearest IT manager so hard that he goes back in time and changes his major to art history.

Besides, eight-character passwords are easily cracked, because they typically represent common password patterns. Real password protection comes from length and uncommon patterns. And, yes, a hacker might still crack a long and unusual password if he gets his hands on a list of encrypted hashes, but even that can be guarded against with honeypots.

But, as password naysayers whine, who wants to memorize a long password? So they are dead, right?

Biometrics have become hot in security circles. But a closer look shows that they simply don't compare to passwords. One reason is flexibility. Password choices are limited only by the imagination, but a person has only so many biometric markers. Dave Aitel, CEO of the penetration testing firm Immunity Inc., wrote in a USA Today article, "It's silly to only have 10 possible passwords your whole life (20, if you count toes)."

Worse, biometrics are generally neither temporary nor secret. Unlike a password, biometrics are easily observable (and therefore replicable) by others, and there's far less you can do about it if one gets compromised. "Today, if your Twitter account gets hacked, you just change the password -- but if you are using a biometric, you will be stuck with that hacked password for the rest of your life," Aitel wrote. "We need to keep that in mind before we start using biometrics to authenticate universal sign-ins and financial transactions."

Biometrics may be more hackable than passwords. Fingerprints, irises, and even chaotic heartbeat patterns can all be mimicked. Fingerprints, once the go-to biometric, have become disfavored since hackers revealed how easy it is to dupe the iPhone 5s fingerprint scanner.

Perhaps the best indicator that passwords are still one's best security bet is the arrest of Ross William Ulbricht, (a.k.a. Dread Pirate Roberts), the alleged Silk Road drug broker. Before arresting Ulbricht, FBI agents followed him -- to the San Francisco Public Library. What were they waiting for? They wanted Ulbricht to open his laptop and enter his passwords. Only after Ulbricht had done that did they swoop in to arrest him and seize his (now conveniently decrypted) laptop for evidence.

Had Ulbricht used a fingerprint scanner or other biometric-based security, law enforcement agents could easily have used his biometric markers to access the machine. Such markers are neither secret nor protected by the Constitution. However, compelling suspects to fork over a password is not always so easy. The US government has repeatedly had to go to court to compel a defendant to reveal a computer password, and it has not always succeeded. This is because a suspect's fingerprints and certain other biometric indicators are physical evidence, so they are not protected by the Fifth Amendment privilege against self-incrimination -- unlike, sometimes, the humble password.

The poor password isn't perfect, and two-factor identification combining a password with a hard token may be better (though a man-in-the-middle phishing attack can defeat that modus operandi). Still, if the full force and might of the US federal government can't always decrypt a perp's password-protected hard drive, declaring the death of the password is not just premature, but downright irresponsible.

Re: Does anyone know
I feel that password will always remain the most widely used security method as the element that requires a high degree of control will cost more and only those will be protected by state of art tech. I think biometrics is a good and valid option all together but must be used where essentialy required

Re: Does anyone know
Of course Nomi, there will be more options available and we will see them with the passage of time. A couple of decades ago it wasn't a practice to keep the password that complex also there weren't any method for dual authentication which is now in place as well. So more options are added when enhancements in the security is required.

Re: Does anyone know
Adil I think there will be more options available to have more security but its need to be found and implemented.

Re: Passwords May Never Die
Curious: Does anyone deploy the fingerprint security yet on the iPhone? 

We use Microsoft Active Sync to provide access to our firm's email on iOS devices and Active Sync does not support fingerprint security access currently.   We can use an iPhone 5s with its fingerprint security feature, however it still asks you to enter a four-digit PIN code as well.  Boo.

So for now, we are investigating other mobile management technologies to supplement Active Sync with an aim toward supporting fingerprint security.  Anyone there already?

Re: Does anyone know
Hayder you are right it makes the password more difficult to hack. Adding special character or number make the password more complex and even for a bruit force it will take a long time to get it cracked. And for every firm it is necessary to secure the gates first and password act like that security.

Re: Passwords May Never Die
@zerox203   I honestly don't understand what the rush is to use biometrics.  Sure it will improve security but hackers will surly find away around this as well.  You raise some great points, we here at E2 take technology for granted in a sense, assuming that everyone is as adept with it's inner workings as we (assume) we are.

But that is not the case, as you mention there are people ( believe it or not ) who do not either have a computer or are adverse to using it.  We have to consider these people ( and dare I say respect them as well ) .   While we wonder whether we are getting three or four G, some still live in the world of the 56k or DSL.

The argument I use here is the same in principle that I use against the Big Data craze.  Let's deal with the data we have before moving into deeper waters.  

The same sort of practical restraint should be practiced when it comes to passwords and Biometerics.
