The JPMC Breach Wasn't About Systems; It Was About People

According to a New York Times article, the major JPMorgan Chase (JPMC) breach was due to a single entry point: a single server in its vast array of servers, one that either has access to confidential data or acts as a gateway to the internal systems, was not fully patched. Does one patch really matter? It depends on what that patch is. A "patch" probably is not the right word for this.
