Abstract: The present disclosure is directed towards systems and methods for adjusting impression inventory within overlapping packages and based on impression inventory reservations. The systems and methods receive attributes of a first package and a second package to create impression inventories for the first package and the second package. Additionally, the systems and methods determine overlap between the impression inventory of the first package and the impression inventory of the second package. Moreover, upon receiving an inventory reservation request, the systems and methods adjust, based on the reservation request, the impression inventories of both the first package and the second package.

Abstract: A system is disclosed for protecting a network against malicious attacks or attempts for unauthorized access. A network is connected to an external network by a number of firewalls. Inspectors detect packets blocked by the firewalls and some or all of the packets are detected to a labyrinth configured to emulated an operational network and response to the packets in order to engage an attacker. Blocked packets may be detected by comparing packets entering and exiting a firewall. Packets for which a corresponding packets are not received within a transit delay may be identified as blocked. Entering and exiting packets may be compared by comparing only header information. A central module may receive information from the inspectors and generate statistical information and generate instructions for the inspectors, such as blacklists of addresses known to be used by attackers.
