An action which this organization should take to find out if systems have been compromised is: C. Look for unauthorized accounts.
<h3>What is a penetration test?</h3>
A penetration test can be defined as a cybersecurity technique that simulates a cyber attack against an end user's computer system, so as to scan, identify, test and check for exploitable vulnerabilities and compromises in the following:
- Operating system
- Web software
- Host device
- Network
This ultimately implies that, a penetration test avails a tester the ability to exploit a weakness and potential security threats on a test network as a privileged user, during vulnerability assessments of the computer system.
In this scenario, we can reasonably infer and logically deduce that an action which this organization or cybersecurity specialist should take to find out if systems have been compromised is to look out for unauthorized accounts.
