White Paper

Integrating Mac Systems into

a Medical IT Infrastructure

Entry-Level Conguration Option

For users interested in a lower cost, entry-level workstation, the following recommended

Apple Mac Pro hardware conguration was list priced at US$6925 at the time of

publication.

• Two 3.0GHz Dual-Core Intel Xeon processors

• 8GB RAM

• 500GB 7200-rpm Serial ATA 3Gb/sec hard disk

• 16x SuperDrive

• NVIDIA GeForce 7300 GT 256MB (single-link DVI/dual-link DVI)

• Standard Apple Keyboard and Mighty Mouse (U.S. English)

• Accessory kit

• 30-inch Apple Cinema Display

Integrating and Securing the Workstation

Integrating any new system requires some important initial steps—namely, ensuring

that the system interoperates with communications and productivity applications

and making certain that it secures patient and hospital data. We followed a logical,

sequential process toward that goal. Key steps included:

• Integrating authentication services, email, and address book directories

• Setting user access controls, both individually and systemwide

• Protecting the workstation against security threats with virus detection software

Directory Integration

The rst step to add the OsiriX workstation was to access directory services so users

could transparently authenticate at le and print servers and make use of the hospital’s

email and address book architectures. Directory services help administer users and their

access to computers, peripherals, and network resources within a multiclient IT setting.

They allow IT managers to uniformly enroll access policies across the enterprise by

structuring users and computers into units and groups. This allows a user to log on to

any computer system within the IT environment to access his or her specic working

environment.

For directory services, however, heterogeneous IT environments can sometimes prove

troublesome. Due to the popular use of Microsoft Active Directory services, Mac OS X

or UNIX/Linux clients are not supported by many IT departments, and some medical

facilities even forbid the introduction of alternative operating systems.

Current Mac OS X versions provide powerful tools for integrating a Mac client system

into an Active Directory and for transparently authenticating users at associated

services like LDAP or Microsoft Exchange Server. Administrators can use the Mac OS

X Directory Access application to specify the details of the integration and to initially

Microsoft Active Directory users logging in to the Mac OS X environment access a

temporary local home directory structure—a structure similar to the standard Microsoft

Windows Desktop. This home directory includes the personal les normally found on

Windows clients and synchronizes with the user’s Active Directory prole upon log-

ging out. Users also can transparently access network resources such as le servers

and printers via the Mac OS X dialogs without the need for redundant authentications.

We also congured Apple Mail and Address Book applications to access Microsoft

Exchange accounts and associated LDAP services, leaving no further actions needed

to integrate the Mac with the hospital’s email and address book architecture.

details via the Max OS X Directory Access application.
