13.3 A fraudulent financial deal has just taken place in the company where you are 
working as a network administrator. The data of the company will be collected in 
such a way that it can be presented in a court of law for the purpose of 
prosecution. Some of the forensic data available for analysis may be damaged 
or destroyed if improperly handled. You have been assigned the duty to 
safeguard sensitive information, logged data, and other legal evidence until the 
first responder or incident response team can take over the collection of 
evidence. To prevent contamination of evidence, you have made sure that each 
device involved is isolated-that is, the device is disconnected from the network 
and secured to ensure that no one else has contact with it until the response 
team arrives. What is the next step that you will take in the event of such an 
illegal activity?

13.4 Donald is a schoolteacher living in Atlanta. While conducting online classes, he 
experienced a momentary decrease in voltage. His computer shut down and 
when he switched it back on, he realized that he had lost some data. He called 
his friend Chadwick who is a network analyst to check out what the issue was. 
Chadwick found that there was a power flaw caused by an overtaxed electrical 
system. Such voltage decreases can cause computers or applications to fail and 
potentially corrupt data. What kind of power flaw caused this issue in Donald’s 
house?
