According to theCCST Cybersecuritycourse, Windows Event Viewer’sSecurity logsrecord authentication-related events that can help identify password-guessing attempts (also known as brute force attacks).

"The Account logon failure event indicates that an authentication attempt has failed, which may suggest incorrect credentials were used. Multiple such events in a short time frame can indicate a brute-force attack. The Account lockout success event confirms that an account has been locked due to repeated failed logon attempts, which further supports the suspicion of password-guessing attacks."

Object access failurerelates to unauthorized attempts to open or modify files, not login attempts.

Account logon failure (B)shows failed login attempts due to invalid credentials.

Account lockout success (C)confirms that repeated login failures have triggered a lockout.
