I’ve stopped covering breaches. First, because clouds are nowhere to be found among them. (The focus of this blog is advice to enterprises that are moving, or have moved, to cloud computing.) Second, because it just seems like piling on a company that’s already in distress.

However, breaches are on the minds of enterprises on the move, due to the latest breach at Equifax.

What we know now about Equifax is that Equifax was aware of the breach well before it announced that hackers had gained access.Hackers made off with Social Security numbers, birth dates, and addresses of 143 million people. That’s enough to steal your identity. A few Equifax people resigned, but that does not fix anything.

Like the other major breaches that have occurred in the last few years, a tool betrayed Equifax: an unpatched vulnerability in Apache Struts, used to support an online dispute portal, provided the hackers with access to the website and attached data.

, but you’d be foolish to think it’s completely safe, at risk of getting complacent and as a result making the kind of mistake that gets you in trouble.

There’s a lot of commentary out there from people—vendors, consultants, and the press—who don’t know what actually happened at Equifax or don’t really know much about enterprise security, yet claim they would have done better. Don’t listen to such people.
