Evolution of High-Performance Networks Introduces New Problems for Security Management

    ATM switches lack general filtering mechanisms.

    ATM can hinder access to encapsulated higher-level protocol information
    • network- and transport-layer header segmentation;
    • application-layer segmentation;
    • IPv6;
    which limits atomic inspection.

    Network bandwidth increasing (much) faster than host speed.
    • contention for network monitor cpu and bus
