Last Revised
The Federal Communications Commission (FCC) has released a public notice encouraging communications service providers to voluntarily use security best practices recommended by the Communications Security, Reliability, and Interoperability Council (CSRIC), a federal advisory committee to the FCC. These best practices help prevent exploitation of Signaling System 7 (SS7) network infrastructure, a signaling protocol that connects communication networks.
US-CERT encourages providers to review the FCC Public Notice and CSRIC's Legacy Systems Risk Reductions Report for more information.
