Broadcasters Need to Keep Eye on Latest EAS Updates

The new TLS protocol update needed before November 8

SUSAN ASHWORTH | RADIO WORLD

It’s time for broadcasters to confirm that their stations are up and running with the latest in EAS updates.

As it stands today, EAS participants are required to not only receive Common Alert Protocol messages from IPAWS but also configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature. Now, an effort to maintain compliance with commonly accepted security standards, FEMA is also taking the next step of removing support for older methods by requiring the use of an updated TLS 1.2 protocol to access FEMA’s IPAWS server, said Sage Alerting Systems and the Society of Broadcast Engineers. TLS, or Transport Layer Security, is cryptographic protocol providing communications security over networks and is often used for internet communications.

To acquire and verify IPAWS CAP alerts, a broadcaster’s EAS alerting equipment must be upgraded with the TLS 1.2 update prior to Nov. 8, 2019.
