Abstract:
1. A network traffic analyzer for use in analyzing a flow of network traffic between a first network and a second network, said network traffic analyzer comprising: a first interface configured for connection to the first network; a second interface configured for connection to the second network; a controller coupled to said first and second interfaces, said controller configured to: scan the network traffic between the first and second networks, wherein the network traffic includes a plurality of data packets; determine, for each data packet of the plurality of data packets, a character set used to encode at least one character included in the data packet by identifying a payload area of each data packet and comparing content of the payload area to a plurality of known character sets, wherein said controller is configured to compare content of the payload area to the plurality of known character sets by comparing groups of a first number of bytes of the content to a first subset of the known character sets, wherein the first number of bytes is a whole number multiple of a number of bytes with which a first subset of the known character sets encodes a single character; and store an indication of each determined character set.
