Message | P2P GNUTella client request |
Summary | A network-internal server has authenticated an external GNUTella client connection attempt and they have begun communications.
|
Impact | Possible policy violation.
|
Detailed Information | GNUTella is a P2P (Peer-to-Peer) protocol for exchanging arbitrary files. Depending on your site's policies, using it may be a policy violation.
If not properly configured, GNUTella clients may accidentally share out confidential files. GNUTella worms (which use deceptive names to encourage download) and viruses may also be accidentally downloaded by a client.
This rule being triggered means that a GNUTella server has been detected on the protected network.
|
Affected Systems | Any system with a GNUTella server installed (available for most platforms)
|
Attack Scenarios | It is possible for an inside attack to take place by using peer-to-peer clients to transfer corporate data from an internal resource to an external third party.
|
Ease of Attack | Simple. This is peer-to-peer activity.
|
Corrective Action | Depends on acceptable use policies.
