A network technician is assigned the task of hardening a Cisco switch before placing it into the LAN. The technician configures and encrypts the user and privilege mode passwords, creates a new management VLAN, and verifies that the IOS is up-to-date. What action should the technician take to ensure that remote access to the system is secure during transmission?
- Restrict VTY ports to only accept SSH connections.
- Configure port security on all Ethernet ports.
- Shutdown all unused Ethernet ports on the switch.
- Configure local users and encrypt their passwords.
Explanation & Hint:
SSH provides security for remote connections by providing strong encryption when a device authenticates (username and password) and when transmitting data between the communicating devices. Using the command on the VTY lines restricts the device to only accept SSH connections. |
