A cybersecurity analyst is tasked with conducting a vulnerability scan to identify weaknesses that an attacker could exploit from outside the network. Which of the following types of scans is BEST suited to meet this specific requirement?
Conducting a scan utilizing internal IP addresses
Utilizing a scan with device fingerprinting capabilities from the demilitarized zone (DMZ)
Performing an external scan
Running a scan from the organization's internal network
An external scan is performed from outside the organization's network perimeter. It simulates an external attacker's perspective and reveals vulnerabilities that could be exploited from the internet. It is the best choice for discovering weaknesses from an attacker's viewpoint outside the network, as opposed to internal scans which are performed from within the network to identify threats that could be exploited from inside.
