The Problem

• Constant New Threats and Vulnerabilities• Current Solutions Not Sufficient

• Reactive Solutions Incur False Positives• Reactive Solutions Miss Unknown Attacks• Do not allow for automatic action

Reconnaissance• 20 types• Precedes Majority of Attacks

Most network attacks are preceded by reconnaissance activity to determine available services and network resources .

Attacker Internet RouterFirewall Enterprise

Typical Attack Process

The network sends information about available hosts and services in response to the reconnaissance .



With this information, the attacker utilizes existing or new exploits to break into the network.



ActiveScout Intrusion Prevention

ActiveScout identifies all reconnaissance used by a potential attacker.


Scout

Site Manager

ActiveScout watches the network’s response, and sends its own unique information to the potential attacker. This unique information, or ‘mark’, is not distinguishable from the network’s legitimate response.


Scout

Site Manager


When the attacker uses the mark to launch an exploit, ActiveScout accurately identifies it and can actively block the attacker.
