Week Eight

 

Assignment Question:

 

It is well known that, the wireless signal of a Wi-Fi network is not confined to a cable as in a traditional network but instead is broadcast through the air. Recently, public Wi-Fi hotspots can be found everywhere, such as airports, hotels and coffee shops. Users can log onto the Internet with their mobile device. Along with convenience, public Wi-Fi hotspots can also provide an easy way for some attackers, like identity thieves and cybercriminals, to attack the wireless network or the users.

 

Please state two kinds of attacks that may occur in public Wi-Fi networks and provide an effective way for users to address the security issues when they access public Wi-Fi on their computer or mobile device.

Week Nine

 

 

Assignment Question:

 

Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility.

 

Cloud-computing providers offer their “services” according to different models. Explain the three basic service models including one example for each.
