Locating and Controlling Sensitive Information

Recent Events

Recent events concerning the distribution and control of sensitive information located on university and personally owned information resources have forced all of us to analyze how we are collecting, receiving, accessing, storing, sending, and destroying sensitive information related to our student, faculty, staff, and business partners. Although the university as a whole can provide guidance to individuals on how to properly interact with sensitive information, it is ultimately up to each university employee to proactively protect the information people have entrusted into our care. Recently the President’s Cabinet has approved twenty-three University Procedures developed by the University Technology Council to help provide guidance related to individual and department responsibilities related to the university information resources including sensitive information. These University Procedures supplement the University Rule 21.01.06.C2 Security of Electronic Information Resources and are published to the University Rules web page. You can also find a consolidated version of these procedures on the TAMUCC Security web site in the Guides section.

One of the major issues facing this university is identifying information resources that contain sensitive information. Although the user of an information resource may not deal with sensitive information on a daily basis there is always the possibility of residual data that the user is not aware exists. To help locate and identify sensitive information all university employees should review all university computers, mobile devices, and removable storage devices and media that they have been assigned responsibility to maintain for any file that contains sensitive personal information. Individuals who have been permitted to utilize personal resources to conduct university business should also check these resources as well. Sensitive personal information includes a person's full or partial name in conjunction with other information such as complete or partial Social Security Numbers, date of birth, driver's license or government-issued identification number, or any financial information such as credit card or bank account numbers.

Locating Sensitive Information

One method for locating sensitive information on systems running Windows, Linux, Unix, or OS X operating systems is to utilize the “Spider” tool developed by security administrators at Cornell University. Detailed instructions for using the “Spider” tool have been included by the Cornell administrators. Using this tool will generate a list of files that may or may not contain sensitive information related to Social Security and credit card numbers. Special attention should be paid to the fact that this tool may misidentify certain files as containing sensitive information. These are generally limited to image files such as JPG and TIFF but may include text documents. Each text file identified should be reviewed individually to determine whether or not it contains sensitive information. Watch the Resources section of the TAMUCC Security web site for more information regarding the use of this tool.

Handling Sensitive Information

Although it is necessary to closely control sensitive information it does NOT mean that the information needs to be removed from an information resource. Individuals who locate sensitive information need to identify whether there is a specific business need to maintain the information on that resource. Any information that has been determined to be unnecessary should be immediately deleted. Individuals who identify files that contain sensitive information that is necessary to complete a specific business function will immediately notify their immediate supervisor for review, clarification, and instructions on how that to protect the information. There are other areas involving sensitive information that should be taken into consideration. Departments and divisions are required to review how they collect and store sensitive information via paper forms. During the review of paper forms, methods and techniques for removing fields associated with an individual's Social Security number from these forms will be considered so as to comply with up coming state legislation. Departments and divisions are also responsible for ensuring that each one of their employees completes a appropriate FERPA training course that will be provided by the university. This training is will be utilized to augment the university's Information Security Awareness training.

Positive Direction

Although these actions may seem a bit confusing and may prove to be initially time consuming the end result of providing proper protection for an individual’s sensitive information will ensure that this university can focus future activities to the normal services we provide to our students, faculty, and staff. Providing a safe and protective working environment for our students and employees has always been a top priority of this university. I assure you that these actions will ensure we are successfully moving down this path. Please contact me directly if you have any questions.
