Difficulty: EasyMobile Device and Embedded System Security

An IT technician is installing several new smart security cameras across an office building. These embedded IoT devices connect directly to the local network. Which of the following actions should the technician take first to prevent unauthorized administrative access to these devices?

  1. Change the factory default administrative password on each camera.Answer
  2. B
    Enforce a corporate Mobile Device Management (MDM) containerization profile.
  3. C
    Install physical bollards near the exterior wall mountings.
  4. D
    Reconfigure the access points to use unencrypted WPA2-Personal authentication.

Answer

Change the factory default administrative password on each camera.
The correct answer highlights changing factory default administrator credentials. Embedded systems and smart IoT devices often ship with standard passwords published in public manuals. Replacing these default credentials immediately upon setup blocks unauthorized administrative access.

Step-by-Step Solution

1
Identify the primary threat vector for newly deployed embedded/IoT hardware.
Recognize that IoT devices are frequently targeted using publicly known default vendor login credentials.
Manufacturers ship embedded devices with uniform default passwords that attackers easily exploit.
2
Evaluate the initial security baseline requirements.
Determine that updating administrative credentials before connecting or exposing devices to the broader network is the critical first defense.
Modifying default logins immediately eliminates automated script-kiddie and botnet compromise risks.
