External vs Internal Vulnerability Scans: Should You Do Both?
Enterprise Storage Forum, April 11th, 2023
Vulnerability scans come in two types depending on which part of the system they're conducted on: internally or externally.
Internal vulnerability scans are performed from inside your network's firewall. This enables them to reveal the most at-risk components of your system, as well as any vulnerabilities that lie in the inner architecture and design of your network.
External vulnerability scans, on the other hand, are performed from outside the network. Those target external ports and IP addresses; scanning the network's perimeter for any weaknesses or vulnerabilities that malicious actors may be able to exploit to gain access into your ecosystem.
