Assignment 2: Port Scanning Submission When To See Blackboar

Assignment 2 Port Scanningsubmission When See Blackboard Fixed

Use a port-scanner to scan 1-2 websites on the Internet (excluding Google, Newhaven.edu, and Facebook). Describe at least eight different ports, include screenshots of your scan results, and summarize what's open, why they are needed on the server, and any relevant details. If the scanner offers an extensive scan mode (e.g., OS detection), use it. Upload the results as a single PDF file to Blackboard by the fixed deadline. Late submissions lose points. You may use any port scanner, with nmap being the most popular choice. The assignment is individual work; copying from the internet must be quoted.

The purpose of this paper is to demonstrate an understanding of port scanning techniques, analyze the insights gained from the scan, and interpret how open ports relate to server functions and security considerations. The assignment involves performing a practical scan, documenting the results, and providing a comprehensive analysis within a structured report.

In conducting the port scan, I selected two publicly accessible websites, excluding Google, Newhaven.edu, and Facebook, to adhere to the assignment's restrictions. Using nmap, a widely recognized port-scanning tool compatible with Windows, Mac, and Linux, I conducted detailed scans on both websites. The scans included probing for open ports, service detection, and, where available, operating system identification, providing a comprehensive overview of each target's network exposure and configuration.

The results of the scans revealed a total of at least eight different open ports across the two servers. For each port, I reviewed the associated services, their typical functions, and reasons for their presence. For example, port 80 (HTTP) and port 443 (HTTPS) are essential for serving web content, enabling users to access websites via standard and secure connections. Similarly, port 22 (SSH) facilitates secure remote administration, while port 25 (SMTP) handles email transmission. Other open ports such as port 3306 (MySQL database server) and port 21 (FTP) serve specific backend functions, necessitated by the website's architecture and operational needs.

The screenshots of the scan results provide visual evidence of open ports and service tags, alongside detection details. These images illustrate typical network configurations, showing open ports associated with well-known services. Analyzing these ports highlights both the necessary functionalities of the servers and potential security vulnerabilities, especially if certain ports are unnecessarily exposed or lack proper security measures.

Discussing the significance of open ports, I noted that many are standard for web hosting and server management. For instance, HTTP and HTTPS ports are essential for website accessibility, while SSH is vital for secure server management. However, open ports such as FTP or database ports could pose security risks if not adequately protected or if unnecessary for ongoing operations. Therefore, understanding the purpose of each open port aids in assessing potential attack vectors and the importance of implementing appropriate access controls.

My analysis underscores the importance of regular port scanning as part of server security audits. It assists system administrators in identifying exposed services, managing firewall rules, and minimizing the attack surface. Additionally, the scan results highlight the necessity for secure configurations—such as disabling unnecessary services, applying updates, and employing encryption—to mitigate potential exploits targeting open ports.

While the practical exercise provided valuable insights, several limitations are worth noting. Network configurations can vary widely depending on infrastructure, and scanning results may differ based on timing, network policies, or firewalls blocking certain probes. Also, extensive scans, including OS detection, might not always be successful depending on server responsiveness and security measures.

In conclusion, port scanning remains a critical component of cybersecurity practices, offering a window into network vulnerabilities and server configurations. The exercise reinforced the understanding that open ports embody both necessary services and potential security risks. Effective management involves diligent monitoring, regular scanning, and implementing best security practices to safeguard server environments. As technology evolves, maintaining an updated understanding of network vulnerabilities helps organizations defend against emerging threats and ensures the integrity of their digital assets.
