Parts of this web site are protected and can only be accessed if you have a DoD Public Key Infrastructure (PKI) or Common Access Cards (CAC) correctly installed in your browser. They are marked with a key icon . Portions of other IAD web sites also require PKI/CAC certificates for access. Explicit instructions for joining other IAD web sites are outlined in the FAQ for each site. Currently, there are no requirements for joining this site; your certificate will automatically be recognized if it is correctly installed in your browser. If need information about obtaining a certificates, see DoD PKI/CAC Certificates.

Portions of this web site use SSL protection to help secure our content. Access to these areas require that a site security certificate is loaded into your browser. Other areas can only be accessed if you have a DoD Public Key Infrastructure (PKI) or Common Access Cards (CAC) correctly installed in your browser. Portions of other IAD web sites also require PKI/CAC certificates for access. Access to these sites and pages requires both your personal certificate and site security certificate. There are two ways to avoid site certificate error messages:

1. Add an exception for the web site (Mozilla Firefox only) or create a Trusted Site (IE only).
2. Import a DoD Root CA 2 Certificate (preferred).

While adding an exception is the faster, easier process, you might have to repeat the process for multiple protected DoD web sites. Importing the DoD Root CA 2 Certificate will take about 2 minutes, but it is the more thorough solution. You should only have to import it once per browser.

You may see some other messages, usually alerts, rather than error messages, even when everything is installed correctly.
