The policies may be composed of packet filtering rules with packet-matching criteria derived from cyber threat intelligence (CTI) associated with Internet threats. These CTI-derived packet-filtering rules may be created offline by policy creation and management servers, which may distribute the policies to subscribing TIGs that subsequently enforce the policies on in-transit packets. Each packet filtering rule may specify a disposition that may be applied to a matching in-transit packet, such as deny/block/drop the in-transit packet or pass/allow/forward the in-transit packet, and also may specify directives that may be applied to a matching in-transit packet, such as log, capture, spoof-tcp-rst, etc. Often, however, the selection of a rule's disposition and directives that best protect the associated network may not be optimally determined before a matching in-transit packet is observed by the associated TIG. In such cases, threat context information that may only be available (e.g., computable) at in-transit packet observation and/or filtering time, such as current time-of-day, current TIG/network location, current TIG/network administrator, the in-transit packet being determined to be part of an active attack on the network, etc., may be helpful to determine the disposition and directives that may best protect the network from the threat associated with the in-transit packet. The present disclosure describes examples of methods, systems, and apparatuses that may be used for efficiently determining (e.g., accessing and/or computing), in response to the in-transit packet, threat context information associated with an in-transit packet. The threat context information may be used to efficiently determine the disposition and/or one or more directives to apply to the in-transit packet. This may result in dispositions and/or directives being applied to in-transit packets that better protect the network as compared with solely using dispositions and directives that were predetermined prior to receiving the in-transit packet.

This disclosure describes embodiments of an improvement to the static group solution because all the administrator needs to do is specify the criteria they care about. Unlike static groups, where the administrator needs to keep track of the status of individual users and move them between static groups as their status changes, smart groups allows for automatic identification of the relevant users at the moment that action needs to be taken. This feature automates user management for the purposes of enrollment in either phishing and training campaigns. Because the smart group membership is determined as the group is about to be used for something, the smart group membership is always accurate and never outdated. The query that determines the smart group membership gets run at the time when you are about to do a campaign or perform some other action that needs to know the membership of the smart group.

Heuristic based approach to authentication of requests in a stateless protocol environment. Heuristics may be applied to a request to calculate a trust level for the request. The trust level for a request may at least in part be based on request parameters for the request and one or more previously received requests in a user context profile. Thus, historical request metadata may be used in calculating a trust value of a received request. If the trust value for a request exceeds a trust threshold, the request may be authenticated without forwarding the request to an authentication server. Thus, for requests in which the trust value exceeds the trust threshold, system performance may be improved by not requiring computational overhead and/or network bandwidth to be used in authentication. In this regard, the format of the request may still comport with the stateless protocol, but authentication may be made more efficient.

Techniques for providing secured, automatic log-in and authentication of a user to a website via a browser executing at the user's personal electronic device (PED) include generating a token based on an identifier of the PED and a user identifier, and storing the token at the user's PED for use in validating and authenticating the user and device credentials against those stored at back-end system and/or in another memory location at the device. Based on the persisted token (and optionally on a user preference), the user may be automatically logged in as the user navigates across restricted and unrestricted portions of the website, and/or to other websites (e.g., without the user's knowledge). At least these features enable automatic log-in and authentication to be performed on an as-needed basis, and/or on a per-device basis, thereby providing significantly more secure access as compared to known techniques.

One embodiment of the present invention provides a switch. During operation, the switch maintains a first counter to indicate a first number of packets in a queue of the switch. The switch then determines whether a clock of the switch has reached a threshold value.

The switch continues to decrement the first counter in response to a packet leaving the queue until the first counter reaches a value of zero. When the clock reaches a maximum value supported by the clock, the switch drops a third number of packets from the queue indicated by the first counter.

A cost effective congestion isolation for lossless Ethernet utilizing random selection is provided. Upon detecting congestion at one of its egress ports, a downstream device randomly selects a data packet received at one or more of its ingress ports for isolation in a congested priority queue at the ingress port.

The systems and methods discussed herein provide for faster communications, particularly for high priority traffic, across a distributed network with multiple exit points to a Wide Area Network. Rather than simply routing traffic based on internal or external destination, an intelligent router may measure latency to an endpoint destination via multiple paths, both external and internal, and direct traffic accordingly. Steering high priority traffic via the internal connection to an exit point near the destination server, and then to the server via the external network, may be faster than simply forwarding the connection via the external network from the exit point closest to the source device. Additionally, to reduce bandwidth requirements of the nearby exit point and provide capability for higher priority traffic, low priority traffic may be redirected back via the internal connection and transmitted via a distant exit point.

Techniques are described for facilitating node protection for Broadcast, unknown Unicast, and Multicast (BUM) traffic for a multi-homed node failure. For example, each VTEP (e.g., PE device) may advertise a protected VTEP address that indicates an IP address of a remote PE device that is to be protected in the event of a node failure. In the event a multi-homed PE device fails, the ingress PE device sends a BUM packet including the protected VTEP address for the failed node. When an egress PE device receives the BUM packet, the egress PE device determines whether the BUM packet includes the protected VTEP address and whether the egress PE device is operating as a backup designated forwarder (DF). If the BUM packet includes the protected VTEP address and the egress PE device is a backup DF, the egress PE device forwards the BUM traffic to the ESI.

A display may include an array of pixels, where each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The thin-film transistors may be controlled using at least first and second horizontal scan line signals. Loading different data values into any given row in the array may cause the scan line signals to exhibit varying rise/fall times, which results in horizontal crosstalk and luminance non-uniformity across the display. The rise and fall times of the second scan line signal are crucial, so the second scan line signal is driven by two separate scan line drivers formed on both sides of the display. Only the fall time of the first scan line signal is crucial, so the first scan line signal is driven by only one peripheral scan line driver and is coupled to an auxiliary pull-down circuit that is only activated during the pull-down transition.
