Proactive worm containment (PWC) for enterprise networks
A proactive worm containment (PWC) solution for enterprises uses a sustained faster-than-normal outgoing connection rate to determine if a host is infected. Two novel white detection techniques are used to reduce false positives, including a vulnerability time window lemma to avoid false initial containment, and a relaxation analysis to uncontain (or unblock) those mistakenly contained (or blocked) hosts, if there are any. The system integrates seamlessly with existing signature-based or filter-based worm scan filtering solutions. Nevertheless, the invention is signature free and does not rely on worm signatures. Nor is it protocol specific, as the approach performs containment consistently over a large range of worm scan rates. It is not sensitive to worm scan rate and, being a network-level approach deployed on a host, the system requires no changes to the host's OS, applications, or hardware.

Methods and apparatus for provision of equalization effort-balancing of transmit (TX) Finite Impulse Response (FIR) and receive (RX) Linear Equalizer (LE) or RX Decision Feedback Equalizer (DFE) structures in high-speed serial interconnects are described. In some embodiments, data corresponding to a plurality of transmit equalization values and a plurality of receive equalization values for each lane of a link having a plurality of lanes is detected. At least one of the plurality of the transmit equalization values and at least one of the plurality of the receive equalization values are selected for each lane of the plurality of lanes of the link based on detection of saturation in a Decision Feedback Equalizer (DFE) tap of a corresponding lane of the link. Other embodiments are also claimed and/or disclosed.
Forward channel variation detection in a wireless communication system
A method in a wireless communication system having a forward channel corresponding to transmissions from a first device to a second device, and a reverse channel corresponding to transmissions from the second device to the first device, includes initiating, at the first device, a first update of a steering matrix. The steering matrix is used to beamform transmissions on the forward channel. The method also includes monitoring, at the first device, a plurality of reverse channel estimates corresponding to the reverse channel, determining, at the first device, a metric indicative of a rate of change in the reverse channel based on the plurality of reverse channel estimates, and initiating, at the first device, a second update of the steering matrix based on a comparison between (i) the metric indicative of the rate of change in the reverse channel and (ii) a threshold.
