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.
Explanation of Solution
Roles of firewalls, intrusion detection systems and antivirus software to promote security:
- Firewall:
- o A firewall denotes mixture of software as well as hardware.
- o It controls traffic flow that is incoming as well as outgoing.
- o The internal networks are been prevented from unauthorized access.
- o It monitors packets with incorrect source or destination and protects internal systems.
- o It offers proxy server by no access to internal documents.
- o It restricts type of messages that get through networks...

Explanation of Solution
Role of encryption and digital certificates:
- The digital certificates join with public key encryption for providing further protection of transaction by authenticating identity of user.
- Digital certificates denote data fields used for establishing sender’s identity and provides receiver with means to encode reply...
Explanation of Solution
Disaster recovery planning and business continuity planning:

- o It denotes back up files as well as maintenance of backup systems or recovery services...
Explanation of Solution
Security problems in cloud computing:
- The company needs to make sure data protection at a level that meets requirements of corporate.
- The company stipulates to cloud provider for data storage based on privacy rules.
- The encryption
mechanism of cloud provider should be verified by company...
Explanation of Solution
Measures to improve software quality and reliability:
- The measures for improving software quality and reliability are shown below:
-
o Software metrics:
- It denotes objective assessments of system in from of quantified measurements.
- It allows department of information systems and end users for combined measure of system performance.
- It helps to recognize problems that occur.
- The metrics must be designed carefully and should have consistent usage.
- The examples of software metrics includes:
- Count of transactions processed within a particular time.

Lab 07: Java Graphics
(Bonus lab)
In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to
implement the following:
➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a
Point (see java.awt.Point) in a PointCollection class (you need to build this).
о The points need to be represented by circles.
Below the drawing panel, you will need 5 buttons:
о
An input button to register your mouse to the drawing panel.
○
о
о
A show button to paint the points in your collection on the drawing panel.
A button to shift all the points to the left by 50 pixels.
The x position of the points is not allowed to go below zero.
Another button to shift all the points to the right 50 pixels.
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.…
If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?
Discuss how business intelligence and data visualization work together to help decision-makers and data users. Provide 2 specific use cases.

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forwardusing r languagearrow_forward8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects.

Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase.
