This lab provides a real world hands on example of performing a baseline

This lab provides a real-world hands-on example of performing a baseline audit of a Windows system. In this lab, you will use WMIC and batch commands to query a Windows system for installed software, NICs, startup items, boot list, disk drives, environment variables, jobs, logons, network protocols, mapped drives, type of OS, installed hotfixes, running servers, shares, installed hardware, running services, user accounts, security groups, running processes, TCP/UDP connections, NetBIOS connections, system information, and scheduled tasks. This comprehensive baseline script captures extensive information necessary for system auditing.

The script’s design prioritizes compatibility and safety across all Windows environments, including sensitive systems like controllers or instrumentation devices. It is built solely on WMIC and batch commands, which require no external dependencies, ensuring universal operability. Moreover, due to its lightweight nature, the script does not cause system crashes or lockups, although it may slow down resource-constrained systems during execution. Proper caution should be exercised to prevent performance degradation in critical or resource-limited environments.

To execute the baseline audit, follow these steps: Right-click on the “baseline.bat” file and select “Edit” to review the WMIC and batch commands used for system queries. Next, right-click again on the same file and choose “Run as administrator” to execute it. A command prompt window will open, signaling the script’s operation. During execution, press Ctrl+Alt+Del, navigate to Task Manager, then Performance tab, and open Resource Monitor to observe resource consumption, particularly CPU usage. It is important to note which processes or operations are consuming the most CPU time to understand the system's current load. After the script has completed, two files are generated: “baseline.html” and “baseline.txt.”

Open “baseline.html” to review the structured, visual output of the collected system information. This file contains organized reports on hardware, software, network configurations, security settings, active processes, logs, and other system details, providing a comprehensive snapshot vital for vulnerability assessment and threat analysis. Conversely, “baseline.txt” offers a raw text view of the same data, providing a broad overview of the current environment to identify potential vulnerabilities, misconfigurations, or unusual behaviors that warrant further investigation. This holistic data collection facilitates effective security auditing and helps in forming baseline profiles essential for detecting deviations and potential threats in the system.

Performing a comprehensive baseline audit of a Windows system is a crucial step in cybersecurity practices, particularly for identifying vulnerabilities, assessing security posture, and preparing for incident response. An effective baseline provides a detailed snapshot of the current system state, encompassing hardware, software, network configurations, and security settings. The method outlined in this lab leverages built-in Windows tools—specifically WMIC (Windows Management Instrumentation Command-line)—and batch scripting, to create an audit that is universally deployable across Windows environments without additional dependencies.

The significance of using WMIC and batch commands lies in their simplicity, speed, and minimal impact on system resources. These tools enable administrators and security professionals to extract a wide array of system data efficiently and safely. This approach is especially advantageous when dealing with sensitive systems, such as industrial controllers or proprietary instrumentation, where stability and availability are paramount. The script's design ensures that these critical systems are not subjected to undue stress or risk of crash, which could occur with more intrusive or resource-heavy auditing tools.

Executing the baseline script involves a straightforward process: editing the batch file to review the commands being run, and then executing as an administrator to ensure full access to system information. During execution, careful monitoring of CPU and resources is recommended through tools like Task Manager and Resource Monitor. This monitoring helps identify any processes or commands that may temporarily consume excessive resources, which could impact system performance or uptime. Once completed, the script generates two key outputs: an HTML report (“baseline.html”) and a plain text file (“baseline.txt”).

The “baseline.html” file presents a structured, easy-to-navigate report that visually summarizes queried data. It includes sections on hardware configuration, installed software, network interfaces, active services, user accounts, security groups, and active connections, among others. This comprehensive report supports security analysts in quickly understanding the current environment, assessing vulnerabilities, and recognizing anomalies that may indicate security threats. The HTML format facilitates readability and can be integrated into larger security monitoring dashboards or documentation systems.

Conversely, the “baseline.txt” file provides a detailed raw text output of the same data, offering a thorough, unedited view suitable for in-depth analysis, scripting, or further processing with other tools. This holistic view allows security teams to evaluate the environment's overall security posture, spot unusual configurations, or detect signs of ongoing malicious activity. For example, abnormal open ports, unexpected user accounts, or unauthorized software installations can be flagged for further investigation based on this data.

The importance of maintaining such a baseline routine is underscored by the dynamic nature of cybersecurity threats. Systems continuously evolve, with new software installed, configurations changed, and vulnerabilities introduced. Regularly created baselines enable organizations to compare current states against known good configurations, thereby facilitating rapid detection of deviations. This proactive security measure is fundamental to effective vulnerability management, incident detection, and compliance auditing.

In conclusion, the described methodology for system baseline auditing makes use of accessible, non-intrusive tools that are suitable for a broad range of Windows systems. By generating detailed reports in both HTML and text formats, security professionals are equipped with valuable data to assess vulnerabilities, monitor deviations, and strengthen overall security postures. This approach epitomizes a practical, efficient, and safe method for ongoing system security assessment in diverse operational environments.
