Military CAC Reader Installation

Military personnel often need to access secure systems requiring smart card authentication. This secure method is facilitated by a Common Access Card (CAC) and a CAC reader. Installing and configuring a CAC reader can be straightforward, provided one follows the right steps.

Requirements

Before starting the installation process, ensure you have the following:

• Common Access Card (CAC): Issued by the Department of Defense (DoD).
• CAC Reader: USB or built-in, compatible with your device.
• Computer: With USB port or compatible reader slot.
• Operating System: Windows, macOS, or Linux.

Software Installation

Different operating systems require specific software or drivers to work with CAC readers. Let’s break down the steps for Windows, macOS, and Linux.

Windows

Start with checking if the default drivers support your CAC reader. Most modern Windows systems come with built-in driver support.

1. Plug your CAC reader into the computer’s USB port.
2. Wait for Windows to automatically install drivers. You might see notifications in the taskbar.
3. If drivers do not install automatically, go to the manufacturer’s website and download the correct driver.
4. Install the driver following on-screen instructions.
5. Restart your computer to complete the installation.

After installation, ensure your browser can work with the CAC reader. Install middleware like ActivClient (often required for DoD systems). You can obtain ActivClient from official DoD sources or your IT department.

1. Install ActivClient by running the downloaded installer.
2. Follow the wizard prompts. Accept default settings unless instructed otherwise.
3. After installation, insert your CAC into the reader. ActivClient should detect it and prompt for your PIN.

macOS

macOS offers built-in support for CAC readers, but additional software might still be necessary for full functionality.

1. Plug your CAC reader into a USB port.
2. macOS should recognize the reader automatically. If it doesn’t, check for updates via the App Store.
3. Install middleware like CACKey or PKard.
4. Download the chosen middleware from the official website.
5. Run the installer file and follow the on-screen instructions.
6. Once installed, test the reader by inserting your CAC and accessing a DoD website.

Linux

Linux can be a bit more complex due to the variety of distributions, but it remains feasible.

1. Ensure your Linux distribution is up to date. Use your package manager to update the system.
2. Install necessary packages. Open a terminal and run:

   sudo apt-get install pcsc-tools pcscd pcsc-ccid libccid

3. Plug in your CAC reader and restart the PC/SC daemon:

   sudo systemctl restart pcscd

4. Test the reader with:

   pcsc_scan

   This should recognize the CAC reader and output card details.

5. Install middleware like CoolKey or OpenSC:

   sudo apt-get install coolkey

6. Insert your CAC into the reader and test accessing a DoD website.

Browser Configuration

After installing the reader and middleware, configure your browser for smart card usage. Below are steps for popular browsers.

Google Chrome

Chrome typically supports CAC out of the box if drivers and middleware are installed.

1. Enter chrome://settings in the address bar and press Enter.
2. Scroll down and click Advanced.
3. Under Privacy and security, click Manage certificates.
4. Import the DoD certificates if not already present. These can often be found with middleware installations.
5. Test by navigating to a DoD website and logging in with your CAC.

Mozilla Firefox

Firefox requires specific configuration to use CAC readers.

1. Enter about:preferences in the address bar and press Enter.
2. Scroll down to Certificates and click View Certificates.
3. Click the Authorities tab and import DoD certificates, which can be found within the middleware installation directory.
4. Set up a security device by clicking Devices under the Advanced tab.
5. Load the module corresponding to your middleware (e.g., “CACKey”) by browsing to its location.
6. Test accessing a secure DoD website.

Safari

For macOS Safari users, the setup is generally simple.

1. Ensure macOS recognizes your CAC reader.
2. Open Safari and try accessing a DoD website.
3. Safari may prompt you to select a certificate and enter your PIN.
4. Install the DoD root certificates if Safari presents any errors. These can be added via the Keychain Access utility.

Troubleshooting

Occasionally, you might encounter issues during the setup process. Here’s a guide to help resolve common problems:

Driver Issues

If your CAC reader isn’t recognized:

• Check Device Manager (Windows) or System Information (macOS) to ensure the CAC reader is listed without errors.
• Reinstall or update drivers from the manufacturer’s website.

Middleware Problems

• Ensure the middleware is the latest version and compatible with your OS.
• Reinstall middleware and restart your computer.

Browser Configuration

• Ensure all necessary DoD certificates are correctly installed in your browser.
• Reset browser settings and reconfigure as per guidelines above.

Contacting Support

If troubleshooting fails, seek assistance from your IT department or CAC resource office. They can provide specific guidance and support.

Common Access Cards are essential for secure access to military systems. Setting up a CAC reader involves careful steps but is manageable with the right guidance. Follow this process to stay up-to-date with secure authentication.
