Abstract: A computer-implemented method, a system and a computer program for identifying malicious URI data items are provided. The method a) gathers URI data items and b) analyses said URI data items to classify them into malicious URI data items and non-malicious URI data items. The method also c1) intercepts communications with malicious servers, identified by malicious URIs, from several computing entities, using sinkholing techniques, and uncovers and retrieves information which is being exfiltrated to said malicious or supervised servers, and c2) periodically monitors a status of the malicious servers identified by the malicious URIs, to control if they have been taken down or not, and simulates an infected bot to get updates of the commands sent from said malicious servers. The method also d) processes the uncovered information with learning algorithms, e) delivers to a mass storage device normalized and interpreted data; and f) provides warnings about potential cyber threats.

Abstract: A wireless medium access control (MAC) protocol and system for implementing the MAC protocol is arranged to operate in such a manner as to avoid collisions from stations (STAs) comprising two or more IEEE 802.11 basic service sets (BSSs), collocated and operating in the same channel during contention free periods (CFPs). The MAC protocol utilizes ready-to-send (RTS)/clear-to-send(CTS) signals that are exchanged during CFPs to avoid potential collision from STAs in overlapping BSSs.

Abstract: Disclosed is a method and system for dynamically selecting a communication channel between an access point (AP) and a plurality of stations (STAs) in an IEEE 802.11 wireless local area network (WLAN). The method includes the steps of: determining whether a new channel between the AP and STAs within a particular basic service set (BSS) is needed; requesting a channel signal quality measure to some of the plurality of stations by the AP; reporting a channel signal quality report back to the AP based on a received signal strength indication (RSSI) and a packet error rate (PER) of all channels detected by the stations within the BSS; selecting a new channel based on the channel quality report for use in communication between the AP and the plurality of stations.

Abstract: A medium access control (MAC) protocol is provided for avoiding collisions from stations (STAs) comprising two or more IEEE 802.11 basic service sets (BSSs) collocated and operating in the same channel during contention free periods (CFPs). The MAC protocol includes hardware/software for utilizing ready-to-send (RTS)/clear-to-send(CTS) exchange during CFPs to avoid potential collision from STAs in overlapping BSSs and hardware/software for providing overlapping network allocation vectors (ONAV) in addition to a network allocation vector (NAV), the ONAV included to facilitate the effectiveness of the RTS/CTS during CFPs.
