SecCompany, Inc. is a fictional name for the company whose label requirements are modeled in this example. To protect the corporation's intellectual property, the company's legal department mandates that employees use three labels on all sensitive email and printed materials. The three labels, from most sensitive to least sensitive are the following:
SecCompany Confidential: Registered
SecCompany Confidential: Need To Know
SecCompany Confidential: Internal Use Only
The legal department also approves the use of an optional fourth label,
Public label is for information that
can be distributed to anyone without restrictions.
At SecCompany, Inc, the manager in charge of Information Protection makes use of all possible channels to communicate labeling requirements. However, some employees do not understand the requirements. Other employees forget about requirements or ignore the requirements. Even when labels are properly applied, the information is not always properly handled, stored, and distributed. For example, reports indicate that even Registered information is sometimes found unattended. Copies of Registered information have been left next to copy machines and printers, in break rooms, or in lobbies.
The legal department wants a better way to ensure that information is properly labeled without relying totally on employee compliance. The system administrators want a better way to control the following:
Who can see or modify sensitive information
Which information is printed on which printers
How printer output is handled
How email at various levels of security is distributed internally and externally
Trusted Extensions software does not leave labeling up to the discretion of computer users. All printer output from print servers that are configured with Trusted Extensions is automatically labeled according to the site's requirements.
Even though security was not yet fully understood at the company, executives knew that Trusted Extensions could implement certain features immediately.
Automatic labeling of print jobs
Printers with restricted access by label
Email with restricted access by label
Each print job is automatically assigned a label. The label corresponds either to the level at which the user is working or to the user's level of responsibility.
INTERNAL_USE_ONLY. At this level,
the work should only be accessible by SecCompany employees and others who
have signed nondisclosure agreements. When the employee sends email to the
printer, the print job is automatically assigned the label
The printer automatically prints a company-specified label at the top and bottom of each page of printed output.
is printed at the top and bottom of every page.
Example 6.1. Handling Guidelines on Banner and Trailer Pages
This example shows the wording for a print job whose sensitivity level
has a classification of
NEED_TO_KNOW and a department of
HUMAN_RESOURCES. Banner and trailer pages are automatically created
for each print job and are printed with company-specific handling guidelines.
NEED_TO_KNOW HR DISTRIBUTE ONLY TO HUMAN RESOURCES (NON-DISCLOSURE AGREEMENT REQUIRED)
Printed below the sensitivity label, handling instructions provides distribution instructions for the printed material. The instructions state that the information should be distributed only to human resources personnel who need to know the information. Also, a reader must have signed a nondisclosure agreement.
Printers can be configured to print only jobs with labels within a restricted label range. For example,illustrates that the legal department's printer has been set up to print only jobs that have been assigned one of three labels:
NEED_TO_KNOW LEGAL – Can be viewed
only by employees with a need to know within the legal department
INTERNAL_USE_ONLY – Can be viewed
only by permanent employees of the SecCompany company and customers who have
signed nondisclosure agreements
PUBLIC – Can be viewed by anyone
This printer setup excludes jobs that are sent at any other label. For
example, this printer would reject jobs at the labels
Printers in locations that are accessible to all employees can be similarly
restricted. For example, printers can be configured to print jobs only at
the two labels that all employees can view,
Similar to how the printer label range controls which jobs can be printed on a particular printer, a user's account sensitivity label range limits which email the person can handle. shows email that is being labeled at the sensitivity label of the user's mail application. The email is sent to the mail application at that label.
Gateways to the Internet were set up to screen email so that emails
at inappropriate labels could not be sent outside of the company. Inappropriate
labels are any labels except
