5.4.5 (cont)Securing a Router & 5.5.1 What Is Virtualization

Securing A Router

• Change default SSIDs & passwords for broadcasting security.

• Use smartphone app or web browser to access the router.

• In main menu, modify Current SSID and apply changes.

• SSID is case-sensitive.

• Changing Wi-Fi password follows similar process: erase old info and replace.

• Devices must reconnect after changes.

Pre-Shared Key

• Type of password for wireless network access in offices.

• Set up by IT when configuring routers/access points.

• Authorized users receive the key but must manage sharing risks.

Physical Device Security

• Lock doors & closets; use cable locks for laptops.

• Ensure all computers have strong login passwords.

• Use biometrics (like fingerprints) for secure logins.

• Routers have built-in firewalls for basic security.

• For complex networks, consider a standalone firewall for enhanced protection.

Virtualization on the Network

5.5.1What is Virtualization?

• Virtualization allows multiple operating systems to run on a single hardware platform.

• It enables the partitioning of a computer into separate spaces for virtual machines (VMs).

• VMs operate as individual systems, performing typical computing tasks.

• VMs can communicate over a network but typically do not share info with the host to mitigate security risks.
