After the breach of the Target payment systems, a class action lawsuit was filed against the company. The action alleges that Target failed to implement strong enough security. Regardless of the merits of this action, it does bring to light a few things that we, as data professionals, should be aware of.
The first is that if our companies store any PII, financial, medical, or other sensitive data, we need to ensure that our management is aware of potential security pitfalls we see, as well as the possibility for legal action if the data is somehow disclosed. The risk and mitigation actions taken need to be weighed by management, and we should approach this as we might any other upgrade or enhancement to a system. With logic, and rational discussion about the issues, providing guidance and potential solutions.
However we also should be aware that no matter what security efforts we undertake, criminals are going to be finding ways around our defenses. As this piece notes, Target likely had security in place, but it’s never going to be enough because the attack vectors and techniques are out-pacing the ability of security techniques to provide protection. The solution, or at least a potential mitigating action, is one that data professionals can help with.
We, and the businesses that employ us, should be incorporating analytics into our defenses to detect abnormal actions, by both external and internal, users. We should be looking for potential ways that data is disclosed, and perhaps even scanning the Internet for potential leaks of data. We won’t prevent all problems, but if we can detect them early, we can limit the damage.
