Every individual person who wants to sign electronic orders for controlled substances must enroll with the DEA to acquire his or her own personal CSOS Certificate.
Before using your personal CSOS Certificate, all four of the DEA’s CA Certificates must be installed. Installing the DEA’s CA Certificates allows your computer to trust your personal CSOS Certificate.
