Event driven route control
Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems. |

Denial of service mitigation
A web server operating in a container has resource and network limits applied to add an extra layer of security to the web server. If a monitor detects that the container's resource usage is approaching one or more of these limits, which may be indicative of a DDoS attack, (step 210) or identifies traffic sources exhibiting suspicious behaviour, such as frequently repeated requests from the same address, or from a related set of addresses, a restrictor function caps the resources allowed by the original Webserver container to allow it to recover from buffer overflow and protect servers running in other containers from overwhelming any shared resources. A duplicator function starts up replica containers with the same resource limits to take overflow traffic, and a load balancing function then directs incoming traffic to these overflow containers etc. Traffic from suspicious sources is directed by the load balancer to one or more specially-configured attack-assessment container(s) where a ‘dummy’ web server operates. The behaviour of these sources is analysed by a behaviour monitoring function over some time to determine if they are legitimate or malicious, which can control a firewall to block addresses identified as generating malicious traffic. |

Enhanced smart process control switch port lockdown
A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected.

Secure permissioning of access to user accounts, including secure deauthorization of access to user accounts
A permissions management system is disclosed for enabling a user to securely authorize a third-party system to access user account data and initiate transactions related to a user account, without disclosing to the third-party system account credentials. The system enables the user to also securely de-authorize the third-party system.

Anti-jamming and reduced interference global positioning system receiver methods and devices
Global navigation satellite system (GNSS) radio frequency signals broadcast from geo-stationary satellites 20,000 km above the earth when received by GNSS receivers are fundamentally weak. Accordingly, these GNSS receivers are vulnerable to accidental and deliberate interference from a range of synthetic sources as well as natural sources. Existing anti jamming technologies such as controlled reception pattern antennas, adaptive antennas, null-steering antennas, and beamforming antennas etc. are expensive and incompatible with many lower cost and footprint limited applications. However, in many applications the GNSS antenna is mounted upon a fixed or mobile element such that accidental and intentional jammers tend to be in the plane of the antenna or below it. Accordingly, there are presented designs and techniques to improve the anti-jamming or interference performance of GNSS receivers by further reducing the responsivity of the GNSS receiver to signals in-plane or below the plane of the antenna. |

Autonomous vehicle system configured to respond to temporary speed limit signs
Aspects of the disclosure provide for a method for identifying speed limit signs and controlling an autonomous vehicle in response to detected speed limit signs. The autonomous vehicle's computing devices identifies a speed limit sign in a vehicle's environment and a location and orientation corresponding to the speed limit sign. Then, the and orientation location of the speed limit sign is determined to not correspond to a pre-stored location and a pre-stored orientation of a speed limit sign that is pre-stored in map information. An effect zone of the speed limit sign is determined based on the location and orientation of the speed limit sign and characteristics of surrounding areas or other detected object before or after the speed limit sign. The autonomous vehicle's computing devices determines a response of the vehicle based on the determined effect zone, and controls the autonomous vehicle based on the determined response. |
