Introduction

Understanding the network and system infrastructure of an organization is crucial in assessing its security posture. This process involves using specialized tools to scan, enumerate, and analyze network devices, operating systems, and services. Such evaluations help identify potential attack vectors, vulnerabilities, and misconfigurations that malicious actors could exploit. This paper discusses the use of a network scanning tool to evaluate a personal network, details the findings, and explores the relevant attack frameworks associated with the identified systems.

Tool Selection and Description

For this assessment, I utilized Nmap ("Network Mapper"), a widely adopted open-source network scanning tool recognized for its robustness and versatility (Lyon, 2009). Nmap provides capabilities for host discovery, port scanning, service detection, and operating system fingerprinting, making it an invaluable tool for security audits. Its scripting engine (NSE) extends functionality with a plethora of scripts that automate various scanning tasks. Nmap operates via command-line interface, offering detailed outputs that assist security analysts in detailed system enumeration.

Network Environment and Target Hosts

In this testing environment, I scanned my home network, which comprises several devices, including a personal computer running Windows 10, a smart home hub, and a Wi-Fi router. The primary target for this assessment was my personal computer, connected via a local Wi-Fi network, with the IP address 192.168.1.10.

Scanning Results and Analysis

Using Nmap with the command `nmap -sV -O 192.168.1.10`, the scan revealed several important details:

Open Ports and Services

The scan identified multiple open ports with their associated services and version numbers:

- Port 22: SSH service, version OpenSSH 7.9p1 (protocol 2.0)

- Port 3389: Remote Desktop Protocol (RDP), version Microsoft RDP 10.0

- Port 80: HTTP web server, Apache 2.4.41

- Port 445: Microsoft-DS (SMB), Samba 4.11.6

- Port 5985: Windows Remote Management (WinRM), version 3.0

Operating System Identification

The OS fingerprinting suggested that the target machine runs Windows 10 Pro, which aligns with the operating system identification (Microsoft Windows 10).

Detected Anomalies and Inaccuracies

During the process, I observed some anomalies:

- The reported SMB version (Samba 4.11.6) appeared somewhat outdated, suggesting potential security holes related to SMBv1 vulnerabilities.

- The tool flagged the RDP port as "possibly at risk" due to weak encryption protocols, indicating a need for configuration review.

- The OS detection was accurate, but the network interface information was incomplete, possibly due to firewall settings inhibiting certain probes.

Discussion of Attack Frameworks and System Vulnerabilities

Understanding the attack frameworks relevant to these systems is vital for constructing defense strategies. The MITRE ATT&CK framework provides a comprehensive matrix of tactics and techniques employed by adversaries (MITRE Corporation, 2021). In the context of my personal network, common attack vectors would include:

- Exploitation of vulnerable services like outdated SMB or RDP configurations, which are frequently targeted for remote code execution (Chen et al., 2018).

- Phishing or social engineering to obtain login credentials, enabling an attacker to leverage Remote Desktop access or Windows management tools.

- Exploiting open ports and unpatched services to establish footholds within the network.

The identified vulnerabilities, such as outdated SMB protocol implementations or weak RDP encryption, are classic attack vectors that align with tactics like Initial Access and Execution as outlined in the MITRE framework. To mitigate these risks, best practices involve regularly updating software, disabling unnecessary services, implementing strong authentication mechanisms, and reducing the attack surface with network segmentation (Scarfone & Mell, 2007).

Conclusion

Conducting an active network scan offers vital insights into the security state of personal or organizational systems. The application of Nmap revealed several operational services and potential vulnerabilities that could be exploited by cyber adversaries. Understanding these attack vectors within the context of established frameworks like MITRE ATT&CK enhances the ability to develop effective defense strategies. Continuous monitoring, timely patching, and informed security policies are essential to protecting modern network environments against evolving threats.
