Windows Systems Breach Detection & Mitigation

I am writing this article to document some information and steps anyone can use to detect and mitigate compromise on their Windows systems. This article will not be highly technical but a resource on Windows systems breach detection and mitigation that someone can use to check the company procedures and quickly identify policies that should be in place and what should be included in those.

At least 600 million attacks per day were officially recorded in Windows systems based on Microsoft Digital Defense Report 2024, without including the number of attacks that Microsoft is unaware of, which certainly raises the number much higher. Such attacks have a significant cost, with the global average data breach cost of $4.96 million per incident based on IBM Cost of a Data Breach Report. Also, Studies estimate a 3-5% revenue drop, which might increase the price by losing clients or impacting the company’s stock if it is in the stock market.

There are two steps the Detection & Mitigation.

In Detection, we can include the following Categories:

Network Traffic Analysis

Analyzing traffic lets us pinpoint unusual outbound connections and check for large data transfers.

User and Account Monitoring

Failed login attempts and unknown new user accounts might be an indication of a breach as well.

Software and Services Audit

Installed software, startup programs, suspicious processes, and unauthorized services need investigation.

Log And Event Analysis

One of the most definite sources of information is the Windows Event Viewer, which should be correctly modified to record any login attempts and privilege escalation. Using the correct tool to analyze and report these proactively has significant value in your prevention policies.

Threat Detection Tools

Every company uses at least one Antivirus with or without advanced protection shields included. Ensure you have a custom policy defined for any software used and notifications properly configured for suspicious behavior.

In Mitigation, we can include the following Categories:

Isolation and Recovery

The first step that you should take when a compromised system is detected. Isolate any compromised OS and restore or rebuild the system.

Incident Response

If you do not have an internal cybersecurity team, engage with experts in forensic analysis to find the entry point and structure a defense strategy to prevent the same breach from reoccurring.

Here are some tools that are freely available to anyone and can significantly help to enhance security and track breaches:

Microsoft Security Response Center

Open Source Security Platform

SysInternal Suite

Key Takeaways:

      Preparing for an attack is the best way to avoid or reduce its impact. Make sure you have your policies and systems ready for such cases. When a crisis hits, the roles and responsibilities become often blurry, and the time to take action is impactful. Inform and train your staff about the procedures that will take place during such an event. Also, train them regularly to indicate and avoid such attempts. Remember that most breaches do not come from technical-aware employees. Periodically audit your systems and stay informed of emerging threats. In this article you can see how you can get the benefits of an open source security platform.
