Unlocking the Secrets of Your Network: A Comprehensive Guide to…

As the digital landscape continues to evolve, the threat of cyberattacks has never been more pressing. With the average organization facing over 2,000 attacks per week, it’s no wonder that cybersecurity has become a top priority for businesses of all sizes. In our previous articles, we’ve explored the importance of PowerShell in digital forensics and incident response (DFIR). In this installment, we’ll delve into the world of audits and ACL security, and how PowerShell can help you uncover potential vulnerabilities in your network.

The Hidden Dangers of Complacency

It’s easy to fall into a routine, especially when it comes to cybersecurity. We become complacent, assuming that our systems are secure and that attacks only happen to others. But the reality is that cyberattacks are becoming increasingly sophisticated and automated. In 2025, global cyberattack activity reached staggering levels, with estimates ranging from 2,200 to over 4,000 attacks per day worldwide. That’s an average of one attack every 39 seconds.

The economic impact is equally alarming, with global cybercrime costs estimated at around 10.5 trillion dollars for the year. And this trend is not slowing down. As new attack vectors emerge and artificial intelligence becomes a force multiplier for attackers, defenders must adapt quickly. The larger an organization becomes, the higher the probability that someone will eventually find a weak configuration or a small vulnerability that can be chained into a full domain compromise.

PowerShell to the Rescue: Workstation Security Audit Script

To combat this threat landscape, we’ll be looking at two PowerShell tools that can give you a deeper understanding of your security setup. The first is a workstation security audit script, designed to provide a comprehensive view of a workstation’s security posture in a clean, readable HTML report.

This script, published by @UK_Daniel_Card, evaluates the system across multiple dimensions, including password security, network protocols, patch levels, exploit protection, and more. The report is organized in a hierarchical manner, with high-impact findings clearly marked, while lower-severity issues are documented with practical recommendations.

For example, the report may highlight a critical issue such as an account without password expiration or an excessive number of local administrators. In many environments, three local administrators is considered a reasonable baseline. Anything beyond that deserves closer attention. At the same time, the report also points out low-level issues that can significantly improve security over time.

The Power of Sysmon

A good example of a low-level issue that can improve security is the recommendation to deploy Sysmon for enhanced logging. Sysmon, or System Monitor, is a Windows system service and driver developed by Microsoft that provides detailed visibility into process creation, network connections, file creation, and other low-level activities. In security operations, Sysmon is commonly used to enrich endpoint telemetry and feed high-quality data into a SIEM. While it does not replace antivirus or EDR solutions, it significantly improves detection capabilities when combined with proper logging and alerting rules.

Active Directory ACL Scanner

The second PowerShell tool we’ll be exploring is an Active Directory ACL scanner. This tool targets areas that teams often miss, providing a deeper understanding of access control lists (ACLs) and their potential vulnerabilities.

Benefits of PowerShell Audits and ACL Security

By using these PowerShell tools, you’ll gain a deeper understanding of your network’s security posture, including:

Identifying potential vulnerabilities and weaknesses
Improving password security and network protocols
Enhancing patch levels and exploit protection
Increasing visibility into process creation, network connections, and file creation
Improving detection capabilities with Sysmon and SIEM integration

Conclusion

In conclusion, PowerShell audits and ACL security are critical components of a comprehensive cybersecurity strategy. By using these tools, you’ll be able to identify potential vulnerabilities and weaknesses, improve your network’s security posture, and stay ahead of the evolving threat landscape.
