Show The Breadth First Search Trees For The Following Graphsdiscussio

Show the breadth-first search trees for the following graphs. Discussion Post 1 System requirements are the configuration that a system must have in order to operate smoothly. System requirements are also considered the minimum systems requirements ("What are System Requirements? - Definition from Techopedia," n.d.). Many of the system requirements support each other to make the informational system more efficient (i.e., availability, reliability, portability, etc.). One system requirement that sometimes gets overlooked for its importance as a part of the system is User Authentication. User authentication prevents unauthorized access to parts of an informational system and ensures unauthorized persons do not gain access to sensitive information like PII. MTC Human Resources should be aware of this because of the high probability of background checks on applicants and the sensitive information involved ("Employment Background Checks without Employee's Permission," n.d.).

Discussion Post 2 When it comes to system requirements, availability is the period during which the system is operational and usable (Requirements, 2018). This is crucial for system performance within a company. Scheduled maintenance or testing can impact availability, so advance notifications with estimated times and durations are necessary for planning. For MTC, availability is vital because multiple departments depend on the system’s constant operation for tasks like recruitment and global expansion. Real-time access allows timely decision-making, and supporting international growth depends heavily on continuous system availability. References: Requirements [Course Resources]. (2018).

Discussion 3 For this assignment, I chose usability, which I believe is essential for end-user satisfaction. Usability refers to how easily users can access and operate a system, including password policies and authentication processes. An effective system should balance security with user convenience, avoiding overly complex or simplistic passwords. High usability reduces frustration and increases security, as users are less likely to adopt insecure practices like writing down passwords or choosing weak ones ("Why Password Management is So Important," 2019). For MTC’s hiring system, ensuring usability is critical because it encourages proper security practices among staff and reduces insider threats through layered authentication measures.

Group 2: For this week’s discussion, select one system performance or security area listed above. Define what this area means using the definitions from Week 5's Requirements reading and explain its importance for the MTC Hiring System. Write about two short paragraphs supporting your explanation with external research. Your initial post is due by Wednesday midnight. Respond to at least three classmates’ posts by Sunday midnight, providing constructive feedback and further insights supported by relevant research.

Paper For Above instruction

The initial instructions requested the demonstration of Breadth First Search (BFS) trees for specific graphs; however, the bulk of the provided text focused on system requirements such as user authentication, system availability, usability, and their relevance to a hypothetical MTC human resources system. These materials encompass different facets of system performance and security, which are critical in the context of information systems security, operational continuity, and user accessibility. The task includes explaining the significance of these areas and their implications for system performance, particularly within organizational environments like MTC, especially considering global expansion and sensitive data handling.

Given the instruction to show BFS trees for graphs, which is a graph traversal technique used in computer science, the main focus here appears to be understanding core system performance/security areas rather than actual graph algorithms. Therefore, this paper will explore how the key performance and security areas—specifically user authentication, system availability, and usability—impact the efficiency and security of organizational information systems, exemplified through MTC’s hiring system.

Understanding Breadth-First Search Trees in Computer Science Context

BFS is a graph traversal method that systematically explores vertices in layers, starting from a root node and exploring all neighbor nodes at the current depth before moving to nodes at the next level. It produces a BFS tree rooted at the starting node, useful for shortest path calculations, network topology analysis, and many other applications (Cormen et al., 2009). When illustrating BFS trees for specific graphs, one visualizes the traversal order and connection paths. While this concept may seem unrelated to system security, understanding graph traversal models equips system analysts to identify vulnerabilities and optimize network structures.

System Requirements and Their Significance

System requirements define the essential features and constraints necessary for the proper functioning of technology solutions within an organization. These include functional specifications and non-functional attributes like security, performance, reliability, and usability (Stair & Reynolds, 2019). The significance of these requirements lies in their influence on system effectiveness, user satisfaction, and organizational security. For example, user authentication is pivotal in ensuring only authorized individuals access sensitive information, mitigating insider threats and data breaches (Santos, 2020).

User Authentication and Security Considerations

User authentication involves verifying the identity of users before granting access. In the context of MTC Human Resources, authentication ensures that only vetted personnel can access applicant data or conduct background checks, thus maintaining data confidentiality (Sharma & Sahay, 2018). Proper layered authentication mechanisms, such as multi-factor authentication (MFA), bolster security against hacking attempts. As cyber threats evolve, organizations must balance usability with security, ensuring users do not bypass protections while maintaining system accessibility (Anderson, 2021).

System Availability and Organizational Performance

Availability refers to the system's uptime and readiness for use, directly impacting organizational processes like recruitment and decision-making. Any unplanned downtime may delay hiring, affect productivity, and hinder international expansion efforts. For MTC, maintaining 24/7 availability is crucial given their global operations, requiring proactive maintenance strategies and real-time notifications of system interruptions (Kuhn et al., 2017). Ensuring high availability necessitates redundant systems, cloud solutions, and effective incident response plans (Simmons, 2019).

Usability and User Experience

Usability determines how efficiently users can navigate and utilize a system. In HR systems, especially those handling sensitive data, usability impacts security adherence—complex password policies might discourage proper security practices, while overly simple policies could compromise security (Nielsen, 2012). A balanced approach involves designing intuitive interfaces and password policies aligned with organizational needs. Good usability reduces training costs and enhances compliance, critical for preventing insider threats or accidental data leaks (Jones & Marsden, 2020).

Relevance to MTC’s Hiring System

The performance and security attributes discussed—user authentication, availability, and usability—directly influence MTC’s operational efficiency and data security. Robust authentication prevents unauthorized access, especially during background checks involving sensitive PII. Ensuring high system availability facilitates timely hiring decisions and supports international growth by providing continuous access regardless of geographic or temporal barriers. Improving usability encourages secure user behavior, reducing risks associated with weak password practices or unsafe system interactions. Collectively, these factors create a resilient, efficient, and secure HR system capable of supporting MTC’s strategic objectives in a competitive global environment.

Conclusion

In conclusion, understanding the intricacies of system performance and security requirements is vital for developing efficient organizational systems. While BFS trees exemplify systematic exploration in graph theory, the principles of structured analysis translate into designing secure, high-performing systems. For MTC, focusing on user authentication, availability, and usability ensures a balanced approach to operational excellence and data security, fostering organizational growth and resilience.
