Alex is asked to conduct a vulnerability scan. He does not know why the scan results are needed. What would be the BEST explanation for him in this situation?

Incident responders are aware that scan results can reveal vulnerable systems and services, which can help in determining how attackers gained access to the systems. However, the scans may not provide information about the specific programs used by the attackers, but they may reveal any services that have been changed or enabled by them. The scans can also show the software versions that were installed before the attack, but this information may not be helpful unless the attackers modified or upgraded the software or the software was already vulnerable. Additionally, the scans may indicate the location of network security devices, but this information should already be available to the incident response team without having to resort to scans to find it out.
