Which of the following is a weakness of a vulnerability scanner?

One weakness of a vulnerability scanner is that it is not designed to go through filters or bypass

security controls like firewalls or intrusion detection systems. Vulnerability scanners typically

perform well in identifying known weaknesses within the perimeter of a network or system but

might not effectively assess systems that are shielded by robust security measures, which can filter

out the scanner's attempts to probe or attack.
