South Carolina's IT Security Failure Teaches Valuable Lessons

Governor Nikki R. Haley of South Carolina has been uncommonly honest about the reasons for the recent Department of Revenue hacking incident, which resulted in the theft of almost 400,000 credit card records, and 10 times as many Social Security numbers.

"Could South Carolina have done a better job? Absolutely. We did not do enough," Haley said.

It would be refreshing to hear, just occasionally, similar frankness from enterprises that suffer security breaches and data losses. Specifically, South Carolina's cybersecurity failures included:

  • Insufficient levels of password security, and
  • Not encrypting Social Security numbers.

One might add inadequate training. The hackers gained access through straightforward spear phishing methods, getting state employees to click on malicious links in emails, which in turn permitted programs to access their accounts and steal their login details.

As a detailed audit by the security vendor Mandiant makes clear, the hackers used valid credentials to access a user account, credentials effectively handed over when the user clicked on the malicious email link. Once inside the account, the hackers leveraged the user's access rights to gain access to sensitive files.

Jim Etter, director of the Department of Revenue, has been asked to resign.

The apparent ability to re-set access rights from within an individual account, with no third-party supervision, is clearly questionable. The apparent readiness to click on links in suspect emails is predictable, but dismaying. The failure to encrypt sensitive data is culpable.

There are three lessons to be learned from the South Carolina experience. The first is that perfunctory security just isn't enough, especially for any enterprise or other organization that maintains databases of valuable personal information. Encryption isn't just optional, single passwords are often not enough, and training in security awareness should be mandatory. That's the first lesson, and it should be obvious.

The second lesson is that being open about what happened -- in the case of South Carolina, commissioning and then publishing a third-party audit -- can actually restore confidence rather than undermine it; as long, of course, as action is taken to remedy the flaws.

The final lesson is a painful one, and it's accountability. It seems unlikely that the director of the Department of Revenue had direct operational responsibility for cybersecurity, but he had a responsibility to see that the job was done, and done properly.

Executives need to understand that cybersecurity is no longer just something peripheral to the IT manager's agenda. In this data-driven age, it's crucial.

Honesty and apology when an organization has done wrong can earn back a lot of lost goodwill, where making excuses and coverup won't. 

Honesty and apology is less work too.

It is refreshing to see officials admit error and take responsibilty for errors and omissions. I wonder how the department heads will be affected and how many scape goats will be found to place blame upon in the situation.

How often do the officials admit their mistakes in the States, I am wondering, because  in Russia, they never do this.They are extremly talented in fiding  a guilty one.

indeed by accepting your mistakes and accepting your own flaws you make it easier for yourself and your organization to earn back its lost reputation.  The resignation of the Director, i hope, will result in some positive changes for the South Carolina's IT Security. They should recover from their flaws and do changes in their systems as soon as possible by  increasing the security and hiring  more IT professionals who are working in advance security ideas to keep their data secure.

And how interesting is it that every post so far reacts positively to the Gov rather than going down the all too familiar path of Deny Deny At All Costs instead takes to the great state of SC  will eat humble pie with some crow thrown in for good measure.

You would think that the main thrust of Kim's blog was the Governor's reaction to the security breach. And I thought political posturing ended a couple of wks ago.

Do you seriously think this will teach lessons for users related to security issues ? I do not think so since if they were to learn there were so many big incidents than this in the past but still the valunerability towards security and personal data is rising daily.

Make no mistake about it: the Director was the scapegoat.  Everybody else gets to keep their jobs, and he's out on the street, and with that well-publicized failure tied to his name to boot.  They should have cleaned house while they were at it, and assured that those who failed to encrypt, those who allowed single-party changes to access levels, and those who allowed inadequate training to continue were all removed (and preferably nailed to the barn door as a warning to others).  Falling on your sword is very noble, but not exactly fair.  Let's ignore the bowing and scraping, and concentrate on what's being done to fix the barn door, now that the horse has gotten out.

I agree it should be,but are you sure we will be secure enough then? I don't think so!
Just as we have find its solution and have started encrypting our sensitive data to avoid uneasiness, in the same way Hackers will soon find its way out too,thus if we really want to be protected we must have to keep  pace with the hackers' growing abilities.

The lessons you identify are spot on and those in responsibility must understand them.

The IT security failure you describe is a serious one, but a good lesson for others to sit up.

I agree with this statement. It's great to see a leader take responsibility for this, although I have a hard time believing that it was really his fault. Sure, he was the person who was in charge of things, but how much do you think that this guy actually knows about IT security? It's not his expertise. The problem here is that the person whose job it was to take care of things like this obviously dropped the ball big time. Time to clear house.
