During the initial setup of a network switch within a company's data center, the network engineer is implementing security measures. What should be the engineer's primary action to secure access to the switch's management interface?
Configure VLANs to separate traffic
Update the switch's firmware to the latest version
Install the latest security patches
Change the default password for the management interface
Changing the default password is essential as it prevents unauthorized access based on commonly known default credentials. Updating firmware, while important for security, does not prevent initial breaches that exploit default passwords. Installing security patches is important but secondary to securing access credentials. Setting up VLANs, though crucial for network segmentation, does not directly affect the management interface's security against unauthorized access.
