Keep your sensitive data secure

Is your organisation responsible for complying with one or more of the many privacy-related pieces of legislation that have been introduced over the past decade? It's a good bet that it is.
Whether it's the Health Insurance Portability and Accountability Act (HIPAA), which addresses healthcare information, the Gramm-Leach-Bliley Act (GLBA), which addresses financial information, or even the Family Educational Rights and Privacy Act (FERPA), which addresses education information, chances are that one of these affects your organisation in some way.
Compliance is nothing to fool around with, and it's imperative that your organisation understands its responsibilities for safeguarding protected data. Protected data is any information that someone could use to identify an individual. Information protected by legislation can include:
- Salary and fringe benefits (except for federal employees)
- Terms of employment (including performance and disciplinary records)
- Academic and educational history
- Criminal investigation and arrest history
- Employment history (including general or security clearance information)
- Biographical history
- Social Security information
- Identification codes
- Personnel profile (including home address and phone number)
- Medical history
Your organisation's network obviously contains and/or processes protected sensitive information. Unauthorised disclosure of such sensitive information could adversely impact your organisation with both civil and criminal liabilities. To protect yourself and your company, it's vital that you implement some extra precautions.
Administrator responsibilities
If you're responsible for the security of your company's network, then you're also responsible for overseeing the day-to-day collection, storage and use of personal data subject to such legislation. You must apply adequate data security safeguards to protect data from the following:
- Inappropriate disclosure
- Improper use
- Access by unauthorised or unapproved users
- Data tampering
Individuals who fail to follow specific requirements can face large fines for violations, as well as misdemeanour charges. That's one more reason your organisation needs to take appropriate security measures to protect sensitive information. But don't forget that security measures, no matter how solid, are only as good as the educated employee who wants to do the right thing.
Employee responsibilities
An organisation's users are potentially the weakest link in your security efforts. You've heard it before, but it's worth repeating: Educate your users.
To better protect sensitive data, train all users to do the following:
- Label all media (for example, discs and documents) containing sensitive information
- Securely store sensitive information
- Immediately notify supervisors of any security breach
- Don't send unencrypted sensitive information via email
- Log off or use a screen saver with a password when leaving workstations unattended
- Erase all data from hard disks before sending PCs off-site for maintenance
- Store data on network drives instead of workstations
- Be on the lookout for hardware keystroke loggers
Final thoughts
Privacy-related legislation grew out of a concern over the potential misuse of the vast amounts and types of personal information collected and maintained on corporate networks, which store, manipulate and transmit the data for a variety of reasons. Don't become a statistic in the news by mishandling protected information — protect that information with adequate safeguards, and train your users to do the same.
