SCEP Certificate-based authentication

BigFix MCM supports certificate-based authentication through Simple Certificate Enrollment Protocol (SCEP). SCEP is the fastest and most secure way to provision certificates to all your MCM-managed devices. With SCEP, IT Admins can automate issuing certificates to the endpoints to provide access to corporate Wi-Fi, VPN, and secure e-mail through encryption.

Advantages of SCEP

  • Facilitates to authenticate users via certificates.
  • Ensures secure network communication, where the data is encrypted and authenticated using certificates.
  • Simplifies certificate distribution to MCM-enrolled devices.
  • Facilitates distributing certificates in huge number of devices.
  • Reduces the burden on Network Administrators as the users can request their digital certificate electronically.
Note: SCEP policy is used for distributing client certificates to devices while WebUI certificate policy is used for distributing the CA certificates to devices.

SCEP architecture and communication flow

Certificate Enrollment Workflow
Certificate Enrollment Workflow
BigFix MCM supports the use of SCEP to authenticate connections to your apps and corporate resources. SCEP uses the Certification Authority (CA) certificate to secure the message exchange for the Certificate Signing Request (CSR). When your infrastructure supports SCEP, you can use SCEP certificate policy created through WebUI to deploy the certificates to your devices.

Using this protocol, SCEP servers issue a one-time password (OTP) to the user transmitted out-of-band (OOB). The user generates a key pair and sends the OTP and certificate signing request to the SCEP server, which validates it, signs it, and makes the signed certificate available to the user.

Applicable devices
