Final answer:
C. Security
Security and Access logs are crucial for identifying potential security breaches in a SQL Server database, with Security logs tracking login attempts and Access logs recording database queries by users.
Step-by-step explanation:
The types of logs that could provide clues that someone has been attempting to compromise the SQL Server database are primarily the Security logs and the Access logs.
Security logs are fundamental in identifying unauthorized attempts to access the system, recording login attempts, and tracking user activity.
The Access logs provide details about which parts of the database were accessed, when, and by whom. While SQL Server does maintain various logs for different purposes, specifically named SQL_LOG is not a standard term; instead, you may hear about SQL Server's transaction logs, which are not primarily used for security purposes but for data recovery.
Event logs might also provide some information about system-level events, including errors or warnings that could be related to security issues.
