A few days ago, security researcher Ira Winkler articulated one aspect of this very plainly.
Why is there a sudden epidemic of violations of sensitive personal information? The answer is, Because it’s there.The scenario of an employee viewing sensitive information that they shouldn't be viewing is a fairly common example of real-world insider security breaches. While it won't likely lead to a $7 Billion loss, it could mean a failed audit, bad publicity, lost customers, or other lost business opportunities. In today's transparent business environment, it's only a matter of time before juicy information is made public. State Dept. employees were probably snooping on passport information for years before they found the 2008 presidential candidates. Then, it got out and became a news story.
Winkler goes on to note:
Anyone developing or maintaining information just better accept that their fellow workers will look at information and that they need to track and limit access. More importantly, they better look at their audit logs and specifically search for violations.I agree. One of the scenarios I often run into is where administrators require access to files (in order to manage access) but they don't require access to the information within those files. A good example is the admin who controls access to HR files and has the ability to open offer letters containing salary and other personal information. To Winkler's point, if the capability is there, they will likely open the files to take a peek. After all, they have been explicitly granted access to those files in order to do their jobs. Doesn't that make it OK? No. And to Winkler's final point, the admin would probably exercise additional restraint if they knew that file access was being monitored.
