`ABSTRACT
`
`A security system for scanning content within a computer,
`including a network interface, housed within a computer, for
`receiving content from the Internet on its destination to an
`Internet application running on the computer, a database of
`rules corresponding to computer exploits, stored within the
`computer, a rule-based content scanner that communicates
`with said database of rules, for scanning content to recognize
`the presence of potential exploits therewithin, a network
`traffic probe, operatively coupled to the network interface
`and to the rule-based content scanner, for selectively divert-
`ing content from its intended destination to the rule-based
`content scanner, and a rule update manager that communi-
`cates with said database of rules, for updating said database
`of rules periodically to incorporate new rules that are made
`available. A method and a computer readable storage
`medium are also described and claimed.
