Carbon Black unveils cybersecurity plug-in

Sterling, Va.-based Carbon Black has added a plug-in to version 2.5 of its security software solution that protects computers against malicious attacks from viruses that maintain persistence after the initial attack through an Autoruns key. The company cited a study conducted last year by information security firm Mandiant, which said that 97% of malicious software operates in this manner. The plug-in monitors each Autorun modification to determine its authenticity, so that users can more quickly identify suspicious behavior.

EWA supports another T-Band waiver request

The Enterprise Wireless Alliance (EWA), in comments filed with the FCC, supported the waiver request of Somerset County, N.J., which seeks to add Part 90 and Part 22frequencies to its existing T-Band (470-512 MHz) license, and to modify its transmitter locations. The EWA said in its filing that the commission’s freeze on T-Band licensing activity nearly a decade before the airwaves are to be auctioned to commercial entities does not serve the public interest, and added that serving the needs of land-mobile-radio users today would represent “more prudent spectrum management.” The T-Band is utilized primarily by public-safety entities in 13 metropolitan markets.
