Network Security and Configuration Quiz

Port security, purchasing a more expensive router, or using a separate firewall device.

Whitelisting specifies allowed IP addresses, while blacklisting specifies denied IP addresses on the network.

Whitelisting can be used to allow specific users, such as children or employees, access to approved IP addresses.

<p>UPnP is not secure due to the lack of device authentication and numerous security vulnerabilities. It considers every device trustworthy and can be exploited by malware to redirect traffic to external IP addresses, potentially compromising sensitive information.</p> Signup and view all the answers

<p>A demilitarized zone (DMZ) is a network that provides services to an untrusted network, typically hosting servers like email, web, or FTP servers. Its purpose is to ensure that the traffic using these servers does not come inside the local network, thereby protecting the internal network from potential attacks by this traffic.</p> Signup and view all the answers

<p>Home and small office wireless routers can mitigate the security risks associated with UPnP protocol by checking the configuration and disabling UPnP, which is often enabled by default. Additionally, using vulnerability profiling tools can help determine if the wireless router is exposed to UPnP vulnerabilities.</p> Signup and view all the answers

<p>A firewall typically manages traffic to and from the DMZ by controlling the flow of data between the DMZ and the internal network, as well as between the DMZ and the untrusted network. This helps in securing the network by regulating the communication and preventing unauthorized access to the internal network.</p> Signup and view all the answers
