ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your organization plans to deploy 5,000 smart temperature sensors across manufacturing plants. Each sensor ships with username admin and password admin. Security policy mandates that default credentials must never be active in production. Which control BEST satisfies this requirement while minimizing hands-on configuration effort in the field?

  • Enable the vendor's zero-touch provisioning to generate a unique X.509 certificate for every sensor at first boot and automatically disable the factory credentials.

  • Retain the factory credentials but configure strong, unique SNMPv3 authentication strings for management traffic.

  • Place every sensor in a dedicated, WPA2-Enterprise-protected VLAN so the default credentials cannot be reached from other network segments.

  • Apply a network ACL that blocks all outbound traffic from each sensor until an installer manually changes the default password.
