Encryption Could Make You More Vulnerable

narramissic writes "It sounds like a headline straight out of The Onion, but security researchers from IBM Internet Security Systems, Juniper, nCipher and elsewhere are warning that the use of data encryption could make organizations vulnerable to new risks and threats. There is potential for 'A new class of DoS attack,' says Richard Moulds, nCipher's product strategy EVP. 'If you can go in and revoke a key and then demand a ransom, it's a fantastic way of attacking a business.'"

It's not so much 'more vulnerable'

[KublaiKhan]

I'd call it 'differently vulnerable' rather than 'more vulnerable'--all things come with inherent risks, and the risks of any particular action must be weighed against the rewards thereof.

Encryption is necessary for many businesses, and if such attacks are truly a worry, they should be addressed in the same manner as any other risk.

Yes, but splashing "MORE VULNERABLE" on a headline preys better on the fears of the uninformed than "DIFFERENTLY VULNERABLE"

We all know headlines exist solely to generate traffic...

Hmm

This sounds more like a problem in the encryption SYSTEM. Its kind of like saying "Encryption makes you weaker because your more likely to use passwords. Which can be brute forced!"

Yes but if encryption leads people to keep records they would not have kept or destroyed otherwise it could pose a risk if its eventually cracked.

Its like Mom always said; never write something down without expecting someone else to eventually read it. If its dangerous or hurtful information it should be destroyed. If its really important keep it in the only place its really safe your head.

Business are keeping more and more customer information. Information is leaked all the time stored encrypted or not. Encryption is likely to give an often false impression of security. People may think they are safely storing facts that will only be available to them and their organization and customers might end up really unhappy if they discover they were wrong about that some time.

5) Buy our stuff!

Really, I've never seen a setup where stealing ONE (or a few) keys could result in a situation where a whole enterprise gets shut down for ransom.

More likely, consider the situation where only two guys have the password to the domain name registrar's account, they get laid off, and a year later some one realizes the company domain expires in two days. Before anyone figures out how to renew it, it's in the hands of a pr0n site. There's your missing/lost key scenario, happens all the time.

Users are always the weakest link

Where I work, we have a policy to have encryption on every laptop. It has to be minimum of 8 characters and include a mix of capital and lower case, a number and one special character. Compared to every other password requirement we have, that's relatively strong.

The problem comes in when people can't remember the encryption password. Either they lock themselves out of the laptop or they do something brilliant like write the password on a post-it and tape it to the laptop case.

No matter what strategy you have, your own customers will find a way to mess it up.

Not new or groundbreaking

This is like saying that using locks on your car can leave you vulnerable. Sure, they keep casual thieves out and the newer systems keep go a long way towards preventing someone from hotwiring your car.

BUT, a mischevious person could put epoxy in all the keyholes, essentially revoking your keys and causing a denial-of-service.

Which is better, a small risk of being locked out of your data/car, or the larger risk of theft and/or misuse of your data/car due to lack of security?
