How many probes do I need?
The number of probes required depends on the network topology and communication requirements between networks.
- One probe is needed for every accessible network. If networks are separated by a firewall or other restrictions, additional probes are required.
- Network Accessibility:
- Single Probe: Networks that can communicate directly require only one probe.
- Dual Probes: Firewalls or other restrictions require two probes for scanning.
- Additional Use Cases:
- Different Gateways: Networks with distinct gateways may need additional probes.
- Different VLANs: VLANs may require multiple probes if not reachable through existing infrastructure.
- Diverse Subnets: Additional probes may be needed if subnets cannot communicate directly.
I am not getting any results - what might I be doing wrong?
Firewalls could be blocking access to specific ports required to perform vulnerability checks. Ensure they allow communication between the probe and target devices on required ports.
