A playbook in a SOAR tool

Suggested answer: A

Explanation:

Regular expressions are powerful tools for searching text based on specific patterns, making them ideal for parsing Linux log files to detect security events with repeatable patterns. In Bash, regular expressions can be used in commands like grep or awk to efficiently filter log data. CompTIA CySA+ emphasizes the use of regular expressions in log analysis for pattern matching, a common requirement for identifying suspicious activities in log files. Options B, C, and D are less suited for this specific task due to their limited pattern-matching capabilities or platform constraints.
