So what steps should you be taking? Well very simply – every single shared identity from the workstation to the database must be protected and changed on a regular basis. Access to a shared account must be logged so that the individual who requires a particular password should be required to provide a reason, and this request should be authorized – dual control.
Each and every administrative/shared/privileged password should be unique. The practice of accepting the same administrative password on every workstation should be discontinued, since having access to the clerk’s password means access to the CEOs machine.
Administrative passwords must be changed on a regular basis, including workstations. This process can be completely automated, which adds the benefit that specific individuals are not aware of passwords until such time as they need them.
Audit logging of every access or request for a password is essential, and this must be done in a manner that it provides non-repudiation for external auditors. In other words can you prove that you are doing this and policies are being adhered to? Can you identify the individual who last had access to any system or application?
Is this paranoia? No – paranoia is wondering everyday if someone is looking over your shoulder. This is simply common sense advice to any enterprise that values its confidentiality, and is not in the business of unnecessary risk. If you value your business, then you should not be wondering if your assets are protected.
