Spoofer looks for two types of spoofing risk:

  • Is your network vulnerable to a spoofed IP attack? Many organizations create internal security access lists only to allow source IPs that belong to their network. This is good “IF” the organization blocks the source IPs from the Internet. Otherwise, a threat actor can spoof your IPs and bypass your ACLs.
