Infrastructure distributed denial of service (DDoS) protection
A method of providing infrastructure protection for a network that includes IP addresses as low as a single IP address. An end user sends traffic to an IP address of a projected server publicly available as an anycast address, and sends traffic to the protected network. The traffic is routed via one of several scrubbing centers using the public IP address as anycast address, and the scrubbing center provides infrastructure protection by scanning and filtering the incoming traffic for illegitimate data. After filtering, the legitimate traffic is encapsulated, e.g., via including virtual GRE tunnel information that includes a secret IP address known only to the scrubbing center and the protected server that receives the network traffic. The protected server decapsulates the network packet and responds back to the end user via the scrubbing network. |

Methods and system for detecting behavioral indicators of compromise in infrastructure
A novel enterprise security solution allows for precise interception and surgical response to attack progression, in real time, as it occurs across a distributed infrastructure. The solution includes a data monitoring and management framework that continually models system level host and network activities as mutually exclusive infrastructure wide execution sequences and bucketizes them into unique execution trails. A multimodal intelligent security middleware detects indicators of compromise in real-time on top of subsets of each unique execution trail using rule based behavioral analytics, machine learning based anomaly detection, and other sources. Each detection result dynamically contributes to aggregated risk scores at execution trail level granularities. These scores can be used to prioritize and identify highest risk attack trails to end users, along with steps that such end users can perform to mitigate further damage and progression of an attack. |

A multipole ion guide (30) including a plurality of rod electrodes arranged at an angle to the central axis (C) is placed within a collision cell (13) located in the previous stage of an orthogonal accelerator (16). Radio-frequency voltages with opposite phases are applied to the rod electrodes of the ion guide (30) so that any two rod electrodes neighboring each other in the circumferential direction have opposite phases of the voltage.

Coil current feedback is used to adjust the PWM frequency and/or duty cycle so as to maintain the current through the coil at a certain level to maintain a desired holding force on the door lock. A degauss circuit inline with the current flowing through the coil is provided. When triggered either in an uncontrolled or controlled manner, a series RLC circuit that includes the coil inductance and resistance causes ringing to occur whereby the coil current reverses direction with sufficient amplitude and duration to degauss the coil. |
