CompTIA CS0-002 Actual Questions

A custom script is a piece of code that can be written to perform a specific task or automate a process. A custom script can be used to gather patch information on a specific server by querying the server’s operating system, registry, or patch management software and retrieving the relevant data. A custom script can be more flexible and efficient than other methods, such as Event Viewer, SCAP software, or CI/CD, which may not provide the exact information needed or may require additional steps or tools.

The Internet usage trend report shows that User 4 has an unusually high amount of data downloaded compared to other users. User 4 downloaded 2.5 GB of data in one day, while the average data downloaded by other users was around 0.2 GB. This could indicate that User 4 is engaged in some suspicious or malicious activity, such as downloading unauthorized or illegal content, exfiltrating sensitive data, or installing malware. Therefore, the security analyst should investigate User 4 further to determine the nature and source of the data downloaded.

The analyst should check if temporary files are being monitored first to respond to the issue. Temporary files are files that are created and used by applications for various purposes, such as storing data temporarily or caching data for faster access. However, temporary files are not meant to be permanent and are usually deleted when they are no longer needed or when the application is closed. Therefore, monitoring temporary files can generate many alerts from the file-integrity monitoring tool that are not relevant or useful for security purposes. The analyst should check if temporary files are being monitored and exclude them from the monitoring scope to reduce the number of alerts and focus on the files that should not change.

UEBA stands for User and Entity Behavior Analytics, which is a category of security products that use machine learning and statistical analysis to identify malicious actions by users or entities on a network. UEBA products can detect anomalous or suspicious behaviors that deviate from normal patterns or baselines, such as data exfiltration, privilege escalation, unauthorized access, insider threats, or compromised accounts. UEBA products can also provide alerts, reports, or recommendations for response actions based on the detected behaviors.
