  • Denial of service (DoS) attack detection systems and methods
    Patent number: 9282113
    Abstract: Methods, systems, and apparatus that enable identification of network attacks such as denial of service attacks are disclosed. A network attack may be identified by monitoring packets received for delivery to devices on a network, and developing a historic packet profile by examining the monitored packets received during a number of time periods preceding an instant time period. An instant packet profile is developed by examining the monitored packets during the instant time period. The instant packet profile is compared to the historic packet profile to determine whether a deviation exceeding a predetermined statistical threshold deviation between the instant packet profile and the historic packet profile is present. The existence of a network attack is identified in response to determining that the deviation exceeds the predetermined statistical threshold deviation.
