Lab 6 Log Correlation Brief Summary

Lab 6log Correlationbrief Summary Of Labin This Lab I Was Reviewing C

In this lab, I reviewed computer logs to identify the perpetrator of a security breach. I collected relevant log files and used both manual examination and Splunk to analyze the data efficiently. The process involved loading the log files into Splunk, then analyzing various events to determine who was responsible for the security violation.

The steps began with uploading the data into Splunk, which confirmed successful integration. Next, I examined several logs, including physical security records, to contextualize events. A key event was the creation of an administrative user account at approximately 9:57. By analyzing the logs around this time, I could piece together user activity and identify the culprit as Drew Patrick.

The analysis process involved specific practices such as reverse searching events and examining user account activity. Using Splunk’s search functions, I tracked user sessions, login times, and account modifications. This method allowed for a detailed review of security events, helping to confirm the timeline and the individual involved. Ultimately, the investigation revealed that Drew Patrick was responsible for the unauthorized creation of an administrator account, leading to the security breach.

Investigating cybersecurity incidents is a critical aspect of maintaining organizational security, especially in environments where digital and physical security measures intersect. In this context, the use of log analysis tools like Splunk serves as an invaluable resource for forensic investigations, enabling security analysts to uncover suspicious activities and pinpoint responsible individuals with efficiency and precision.

The primary purpose of the lab was to review various logs to establish the involvement of a specific user in a security breach. The process began with collecting relevant log data, which included system logs, user activity logs, and physical security records. After data collection, the next step was to upload these files into Splunk, a leading security information and event management (SIEM) platform capable of indexing, searching, and analyzing security data in real-time. This step was crucial, as it facilitated a comprehensive view of the security events and allowed for automated searches that would be cumbersome manually.

Once the data was loaded into Splunk, the analyst conducted an initial review to verify successful ingestion. This involved examining logs for errors or inconsistencies and confirming all relevant log types, such as user login/logout records, account creation logs, and physical access logs. With the data confirmed, the investigation targeted specific events, notably the creation of an administrator account at around 9:57. This event was pivotal because it marked the point at which a potential security compromise occurred.

Analysis revealed that around this critical time, the user Drew Patrick was active on the system. Using Splunk's search capabilities, the analyst performed reverse searches to trace user activity, identify login times, and correlate user actions with physical security logs. This process involved filtering logs by timestamp, user account, and event type to narrow down potential suspects and establish a timeline of activities.

Part of the investigative process also involved examining user account modifications and access privileges. By correlating log entries related to account creation with physical location data, the analyst confirmed that Drew Patrick was responsible for creating the administrative account during the event window. The timeline established through this analysis was instrumental in linking the suspect’s activity to the security breach.

In conclusion, the effective use of log analysis tools like Splunk enabled systematic investigation of the security incident. The combination of manual review and automated searching helped identify the responsible individual accurately and efficiently. This process underscores the importance of comprehensive log management and analysis capabilities in modern cybersecurity practices, especially when physical and digital security events are interconnected. Vigilant monitoring, coupled with analytical tools, can significantly enhance an organization’s ability to respond to and prevent future incidents.
