Abstract
Identifying a questionable network address from a network communication. In an embodiment, a network device receives an incoming or outgoing connection request, a web page, an email, or other network communication. An evaluation module evaluates the network communication for a corresponding network address, which may be for the source or destination of the network communication. The network address generally includes an IP address and a port number. The evaluation module checks a predefined white list for the network address to determine whether the network address is valid. Depending on the result, the evaluation module sets an indicator for preventing, allowing, or warning about the network communication. A category code, security code, organization code, or function code, may also be checked against the white list to ensure a valid network node is not compromised. A domain name may also be determined from the network address to further validate the network communication.
