Chapter 8, Problem 1RQ
Program Plan Intro
System vulnerability:
- When huge data amounts are been kept in electronic form, it becomes susceptible to many threats.
- The information systems in many locations are been interconnected through communication networks.
- The unauthorized access can occur at many access points in network and is not limited to single location.
- The data flowing over networks could be accessed; valuable information could be stolen while transmission or data could be altered without authorization.
- The denial-of-service attacks are launched by intruders to disrupt website operations.
- Internets are vulnerable than internal networks as it is open to everyone.

Malware:
- A malware denotes a program that is harmful to a computer user.
- It includes viruses, worms, Trojan horses and spyware programs that gather information without user permission.
- Virus:
- o A program that would replicate itself by being copied.
- o It may initiate copying to another program, document or computer boot sector.
- Worm:
- o It denotes a virus that is self-replicating and does not alter files but resides in active memory.
- o It duplicates itself without human intervention.
- Trojan horse:
-
o A program in which malicious code is contained inside data or
programming that is harmless. - o It is not a virus as it does not replicate, but it denotes a way for other malicious code to be introduced into system.

The assignment here is to write an app using a database named CIT321 with a collection named
students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should
know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes
for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be
extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of
class.
The database contains 51 documents. The first rows of the CSV file look like this:
