PROGRAM REQUIREMENTS

In this assignment you will implement three basic graph algorithms: breadth-first search, depth-

first traversal, and topological sort. We are not providing any code template, but you must follow 

the input and output formats specified below. Read carefully what you are required to do to 

receive full credit and attempt the extra credit tasks only after you are done with the 

requirements. 

First, implement a graph data structure using adjacency lists. Your code must read graphs of 

arbitrary size from a file (as long as there is enough memory available, your code must work: do 

not assume a maximum number of vertices). The input format is as follows: one line per vertex, 

the first element is the vertex id and the following numbers are the adjacent vertices. The input 

file will always be a bunch of integers and white space. For example,

1 3 4 

2 

3 1 4 

4 1 3

is a graph with four vertices, and three undirected edges: (1, 3), (1,4) and (3,4). 

Then, implement three algorithms: 

• Breadth-first search. Calculate the distance from vertex 1 to all other vertices using BFS. 

Then, print all the vertices sorted by distance from vertex 1. Note that if the graph is 

unconnected, some nodes may have distance ∞.

• Depth-first traversal. Calculate discovery and finish times using DFT. Then, print all the vertices sorted by discovery time.

Topological sort. Print the topological sort of the graph. 

A few comments:

• Look carefully at the sample input and output files and follow the same format. 

• When you look through vertices, visit them in increasing order.

Extra credit: 

• Use BFS to determine whether a graph is connected. The input is a graph, and the output 

is yes or no.

• Implement an algorithm to detect whether a graph has a cycle. The input is a graph, and 

the output is yes or no.

• Design and implement an algorithm that takes as its input a graph ???? = (????, ????) and a 

permutation of ????, and outputs whether the permutation of ???? is a topological sort of ????.

Your algorithm must run in Θ(|????| + |????|).

Week 9 – Discussion

In a corporate, networked setting, should end users be allowed to install applications on their company workstations, whether the applications are on a DVD or downloaded from the Internet? Be sure to weigh security against usability. 

Internet Research – Wk 9

For this assignment, you are asked to locate any company privacy policy. Some of the more popular ones might include GOOGLE, APPLE, or MICROSOFT, but you may elect to review another agency.

Cloud computing offers a variety of service to its users and so is the audit of it multifunctional and multi-directional. The purpose of the audit can be many and based on that the audit report can reveal different information about the cloud computing audit. The scope of cloud computing audit in my the business will include the IT and its controls of the business as well as the administration, risk assessment, communication, monitoring several activities, system operation, logical as well as physical access and finally change management. “The importance  of  IT  auditing  and  especially  cloud  computing auditing  is  an  essential  effort to  ensure  the  proper  functioning processes  of  an  the organization’s  IT  systems,  management, operations, and  related  processes,  to  avoid  fraudulent,  in  order to  have  comprehensive  and  accurate financial view of their business” (Moghadasi, 2018).

The IT structure of the cloud computing of the business is the basic that needs to be understood to ensure that everything is in proper condition and place so as to enhance the overall business and the output and this is effectively understood by an audit of cloud computing structure. Another important area being targeted by the audit is risk assessment. With the advances in the cyber field, the types of risks to have advanced. Thus the business needs to have thorough knowledge about its cloud computing and related risk so as to take security measures against them. Cloud computing audit for risk assessment reveals information about qualitative and quantitative aspects of the risks and thus becomes crucial in securing the business from any future attack or breaches. “The outsourced data, however, in the cloud are not always trustworthy because of the inadequacy of physical control over the data for data owners” (Sookhak, 2017).

The activities being performed on the cloud can be monitored by the audit of it. It helps the business owner understand what employees are doing on the cloud and how fruitful an employee is towards the overall development and growth of the business. Any activity being performed which is not related to the work profile of the employee can thus be revealed in the audit so the business can take appropriate measures against such employees or clients. “Despite regulatory interest in the audit impact of new technologies, little empirical work has studied how auditors behave when clients introduce cloud platforms into their accounting information system” (Banker, 2020).

The organization systems operation is also an important scope of cloud computing audit. It investigates the working of several systems and informs what systems need to be upgraded or changed for better results. The communication happening on the cloud is a part of audit wherein the business owner gets to know who is communicating over the cloud and who is viewing the information stored overcloud. Any unauthorized access being taken by a third party to the cloud services will be revealed in the audit report thus helps in blocking such access and improving the accessibility features for the enhanced security of the business cloud computing (Moghadasi, 2018).

Cloud computing auditing ensures the proper functioning of the IT system, the operations, the management, and the related processes. It helps to avoid fraudulently that provides a comprehensive and accurate financial view of the business. Nurhajati states that cloud computing audits are relevant towards protecting the data, identification and access management, risk technology, setting up rules and ensure better operations (Nurhajati, 2016). It is through cloud computing audits that points out the risk that is related to cloud computing that ensures business continuity.

The objectives that are required to be covered by cloud audit is to provide the stakeholders with having an internal security policy and towards having a successful control process of the cloud computing service. It also helps to evaluate the productiveness. The purpose of cloud audit is also to provide an interface between the service provider and the clients of the company. It helps to identify the definiteness and the inadequacies that can be found in internal control. It also provides the assessment criteria and generates the capabilities of reporting (Marks, 2015). Thus the stakeholders become much more confident in regards to the quality of the audit that also ensure better internal control.  The auditors are also required to consider the control access, the control framework, and the features of authorization, notification in regards to a data breach, latency in communication and also take into consideration international law. The cloud auditor is also required to consider the cloud support and the IT support functions and towards anticipating re-enforcing the business function.

The cloud auditors are required to understand the risk association, the ways to deal and towards developing the abilities towards auditing the plan and the strategy. As the architecture for cloud computing consists of different models different components and services, it is required for the cloud auditor towards considering if the application is compatible with that of the cloud environment (Moghadasi, Mousavi, & Fazekas, 2018). This is because most of the application depends on the internal network of the organization and not the internet. Further, the web applications are required to be accessed that would assure authentication, monitoring, and access control. The cloud auditors are also required to assess the appropriateness of the control access over the other resources. They are required to access the endpoints and ensure that there is sufficient security. This would help towards gaining legitimate access towards the cloud resources (Halpert, 2011). Moreover, the service level agreement is required to be considered all communication and correspondence between the different vendors.

The audit process encompasses various phrases which include the planning process. In the planning process, it is required to understand the nature of the business. In the planning process, it requires examination of the controls and the procedures, the structure of the organization, the terms and the reviews and also understanding the application and also the comprehensive control review (Halpert, 2011). The next stage is the control examination phrase where the auditor is required to access the quality and towards specifying the degree to rely on. They are also required to execute and examine the control and test the outcome.
