Chapter 8, Problem 4RQ
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.
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
Encryption protects information:
- It denotes coding as well as scrambling of messages used to secure transmissions over internet...
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:
- Disaster recovery planning:
- o It creates plans for renovation of services after any event of natural calamity.
- o It focuses on technical concerns involved in keeping systems functioning.
- 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.
- Online response time...
-
o Software metrics:

The Horse table has the following columns:
ID - integer, auto increment, primary key
RegisteredName - variable-length string
Breed - variable-length string
Height - decimal number
BirthDate - date
Delete the following rows:
Horse with ID 5
All horses with breed Holsteiner or Paint
All horses born before March 13, 2013
To confirm that the deletes are correct, add the SELECT * FROM HORSE; statement.
Why is Linux popular? What would make someone choose a Linux OS over others? What makes a server? How is a server different from a workstation? What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
Objective you will:
1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five)
2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector.
3. Compare the performance of TreeSort with C++'s std::sort on large datasets.
Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST):
1. Insert all elements into a BST (logically sorting them).
2. Traverse the BST in-order to extract elements in sorted order.
3. Store the sorted elements in a vector.
