Tackling the Insider Threat - 0 views

Karl Wabst on 21 Apr 09Times are tough, and we all continue to hear about the heightened risk of the insider threat. Granted, unauthorized insider access to data has always been a concern. But the concern is increased now because of the tremendous changes that we are seeing in the economy. The term "disgruntled employee" now has a whole new meaning because there are more and more folks concerned about 'What if my job disappears? What kind of information can I keep? What kind of information can I have access to?' As one who's dealt with the insider threat, I have some questions of my own: What do you really mean by an insider? In our borderless world, the terms "insider" and "outsider" overlap. "Insiders" are not just employees and staff, but also service providers, business partners, consultants, contractors -- any number of parties who may work for companies we deal with. What do we really mean by an authorized versus an unauthorized insider? If you take a look at the Societe Generale situation, allegedly a fraud was committed by an authorized user with privileges he was not supposed to have. How? Well, the horribly overused cliché is that if you work with a company long enough, eventually you will have access to everything, and no one will know it. Bottom line: As people change jobs within a company, we are not good at updating their roles and responsibilities. If you look at all the efforts that have been spent on identity and access management products, the biggest challenge is trying to understand: What are the roles and responsibilities you are trying to apply to people? How do you develop these roles and responsibilities and how do group them? How do you really deal with people who have to change roles and responsibilities? How do you add and delete roles and responsibilities as people change jobs?
