M11: Secure Networking

What is UPnP used for?

• It allows your computer to discover your mouse without a special firmware update

• It encrypts smart home devices

• It makes it easier for devices in your home to discover the network and use the internet

• It prevents DDoS attacks

What issues does the UPnP setting on your router present (if enabled)?

• It can enable your household devices to be included in botnet armies

• None of these - UPnP improves security of your router

• Not as secure as WPA2

• When pushed, someone can log onto your network without a password

Why should you update your router's firmware soon after release?

• It secures the DHCP of your home network each time it is updated

• It usually allows remote management settings to be updated by your internet service provider

• Security patches in new updates, if not applied to your network, leave vulnerabilities open for hackers to exploit

• SSID in new updates help to secure your home network

_______ monitors and controls the traffic flow between the Internet and private network on the basis of a set of user-defined rules.

• Firewall

• Firmware

• SSID

• WPS

________ prevents outsiders from identifying the addresses of individual devices on the network.

• Hardware on your computer

• Network address translation system

• SSID

• WPS encryption

Which of the following is true of MAC addresses:

• no two devices have the same address

• Not every device connected to the network has a MAC address

• they are only used on Apple computers

• two devices in the same network may have the same address, but the router will assign a unique number to the network

One reason that MAC address filtering is easy for hackers to get around is that:

• A device that does not typically use a MAC address can be used to access the network instead

• a hacker may still be able to ask an employee for the password

• packet sniffers can see active MAC addresses on a network and can change their address to one that is active

• they can use a different SSID

CHECK ALL THAT APPLY: Some ways to keep devices in your home healthy are to:

• Backup data in a secure location

• Enable WPS

• Keep firmware up-to-date

• Use anti-malware
