Critical infrastructure requires precise timing to operate. This reliance makes the infrastructure vulnerable to disruptions in timing that can be either intentional or unintentional. Intentional disruptions can be caused by GNSS jamming or spoofing or network attacks.. Unintentional disruptions are usually caused by equipment failures or acts of nature. Back in April 2022, Alliance for Telecommunications Industry Solutions (ATIS) hosted a webinar on this topic, a precursor to the Annual Workshop on Synchronization and Timing Systems (WSTS). The webinar featured top industry experts deliverin ..read more
