Shown below is the matrix used to determine the risk level of threats, spyware, and anti-virus.
An application that is generally used for system to system communication that facilitates network operation. This includes most of the IP protocols.
An application that uses a client-server model where one or more clients communicate with a server in the network.
An application that communicates directly with other clients to transfer information instead of relying on a central server to facilitate the communication.
An application that relies on a web browser to function.
Capable of File Transfer
Likely has more than 1,000,000 users. Has the capability to transfer a file from one system to another over a network. A streaming app that has no other mechanism to transfer files other than the video or audio streaming should not be flagged as able to transfer files.
Used by Malware
Malware has been known to use the app for propagation, attack, or data theft, or is distributed with malware.
Excessive Bandwidth Use
Consumes at least 1 Mbps on a regular basis through normal use.
Uses a port or protocol for something other than its originally intended purpose with the hope that it will traverse a firewall.
Likely has more than 1,000,000 users.
Has publicly reported vulnerability. For web-based apps, it should also be set to yes, as HTTP always has vulnerability.
Prone to Misuse
Often used for nefarious purposes or is easily setup to expose more than the user intended.
Tunnels Other Apps
Is able to transport other applications inside its protocol.
Should be set if app can upload or download a file-type over a decodable protocol (e.g. http).
Should be set if the app can upload or download an executable file over a decodable protocol.
Same as spyware ident.
For web-based apps, the vulnerability-ident should always be yes, since they are http and http always has some vulnerabilities.
For web-based apps,deny-action should be set to drop-reset (unless there is some issues with the app receiving tcp-reset).
