Free CompTIA CySA+ CS0-003 Practice Question

A company's IT department is alerted to abnormal network behavior. Upon inspecting system logs from network devices, analysts observe numerous failed authentication attempts to a key resource followed by an unexpected, successful sign-in during off-hours. None of the attempts correlate with standard user activities or scheduled jobs. What does this scenario most likely suggest?

  • An external brute force attack might have occurred, leading to unauthorized access with higher-level privileges.

  • The legitimate user of the resource might have had trouble remembering their credentials and finally logged in successfully.

  • A periodic system update task could have triggered the sequence of sign-in attempts, eventually gaining access.

  • The resource was rebooting multiple times, causing a series of access entries from the management console.
