Verizon: Security Compliance Coming Up Short

If recent, highly publicized data breaches weren't proof enough, a report that Verizon Enterprise Solutions will issue next week shows businesses aren't doing an adequate job of maintaining compliance with security standards by constantly testing their systems.

Verizon issues two annual reports per year, one tracking data breaches and another detailing compliance with the Payment Card Industry (PCI) Data Security Standard. The PCI report, due out next Tuesday, shows that businesses are treating PCI DSS compliance a bit too casually. While a growing number (82%) of businesses meet overall PCI standards, less than one-quarter are doing the required regular security testing and even fewer (17%) the security monitoring that would detect breaches and enable a fast response. (See Verizon Finds Credit Card Security Iffy, Verizon Breaks Down Security Threats by Industry Segment, and Verizon: Hackers Still Using Old Tricks.)

While Verizon isn't commenting on the specific breaches at Target and Nieman-Marcus, that lack of ongoing testing and monitoring would explain why data breaches persisted for weeks or even months before being detected and stopped. "We can see an improvement overall across all industries in PCI compliance, but we also see that security testing is not performing well," says Ciske Van Oosten, an architect of the upcoming report and part of Verizon's PCI Security Practice, which does security assessments, program and project management, and risk assessments for businesses. "We know there is now increased awareness of data breaches but whether that leads to doing right things in terms of internal and external integration testing, we will have to see." (See Verizon Ventures into Risk Management.)

Because attacks are growing both in size and sophistication, and because newer attacks don't yet have signatures to make them detectable by malware prevention programs, it's important that businesses do daily testing and monitoring to maintain PCI compliance, Van Oosten says. Generally following a breach, a review of the invaded company's data logs show red flags indicating suspicious activity that could have been detected earlier and addressed, he adds. But even small companies handle such a volume of data that only automated daily monitoring would be effective.

"The PCI standard requires you to remain up to date -- on a daily basis with log monitoring, and that process needs to be automated, even if you have only a single server," Van Oosten comments. "Compliance in not just reducing the chance of being breached, it can help you respond sooner to it and contain the cost of a breach. But that means ongoing testing."

Most breaches today are detected by law enforcement or third parties, not by the businesses themselves, which catch less than 10% of the breaches.

Companies can also improve their chances against data breaches by using up-to-date software systems, by encrypting information at its point of entry into a company's network, and by maintaining separate secure status for the encryption keys. The latter approach would prevent most data captured in a breach from being used in a criminal way, unless those who steal the data are able to steal the encryption keys separately, he adds.

Re: It's all about the Benjamins
Seven -- Agreed -- we should be less concerned about individual dumb users than about people on the inside, whether dumb or corrupt. As your examples point out, internal stupidity and criminality are potentially orders of magnitude more damaging than someone hacking one external user's weak password. I've been hacked twice on credit card accounts, and both times it was obvious that the hacking was an inside job. And of course, there's Mr. Snowden.

What would constant review have accomplished?
Monday morning quarterbacking is always easy. I dare say that when humans are involved, the bad guys will always have the upper hand. To say that more monitoring would help is a cheap shot by Verizon. What happened to Target would have happened to any company in the retail business. 

Quite simply the bad guys have the money to hire creative pen-testers, and all it takes is one crack to get in. Whereas, the good guys have to do battle against EVERY possible crack.

Re: It's all about the Benjamins
I guess it all depends what you call "a lot".

ESET is a credible outfit and they have presented evidence below of some subscribers becoming more self-conscious about their on-line behaviour and hesitating to follow through on impulses where before they wouldn't have.

http://www.welivesecurity.com/podcasts/is-nsa-surveillance-affecting-online-behavior/

As you say, it's perhaps not "a lot" thus far. But the industry has got used to such a ferocious pace of consumption by consumers that even the prospect of a slight slowing in the rate of acceleration hasn't tended to figure much in people plans up until now.


Definitely something to watch verrrry closely I would think.

Re: It's all about the Benjamins
 

Ladies and Gentlemen,

 

I am providing a link here:

http://gcn.com/articles/2011/06/30/dhs-test-found-thumb-drives-disks-network.aspx?s=gcndaily_010711

To demonstrate that this is actually a lot harder than it may seem.  The biggest single issue in corporate security is users.  They do stupid things.  How many of you don't mouse over links in e-mails before clicking?  One example.  

In the case listed (from a couple of years ago), a number of usb flash drives were left in parking lots of DoD offices and contractors.  60% were plugged in.  Yes 6 0 not 6 not .6 but 6 out of 10.

If somebody wants into your network, they will get in.  That is a given.  It is not a question of IF they can get in it is HOW MUCH it will cost and HOW LONG it will take.  Let's use Target.  Imagine giving an IT security guy $1M as a bribe to let a hacker in.  Think you might be able to find someone in your organization disaffected enough to take a substantial bribe?

Then we get to the electronic bits of this.  Networks and systems are probed constantly.  You couldn't actually investigate every attempt as you probably have thousands per second at a major institution.  Most are simple enough to defeat, but the volume of stupid attacks makes finding that needle (aka the one sophisticated hack) a real hard bit to locate.

Security is imperfect in the non-electronic world.  Why do we expect that there is perfection in the electronic version?

Re: It's all about the Benjamins
I'm supposed to be the cynical curmudgeon. You're forcing me out of my comfort zone. Yes, in many ways we are the dull-witted sheeple that some outside observers make us out to be. But even Target has said publicly that the data breach has cost it business.

I am cynical on this subject. I don't see a lot of evidence that businesses and consumers are changing their behavior as a result of data breaches.

110 million (!) accounts potentially compromised -- that's close to the total number of US households. Don't see how that can be quickly forgotten.

Re: It's all about the Benjamins
I think it remains to be seen whether Target is  hurt long-term. They had tried to become a one-stop shop for bargain folks with taste (the folks with tight budgets that couldn't stand Walmart) by adding groceries. But from what I'm reading and seeing, folks are thinking twice about relying on their Red Cards to the extent they used to. 

It couild be this is quickly relegated to yesterday's news. At some point, though, consumers are going to balk at never knowing if their credit card data is sescure. 

There is also the issue of ongoing ramifications from the Target breach. People are still getting notified by banks and others than their accounts have been breached.

Will Target's brand really suffer long-term damage? Or will this be forgotten soon enough?
