47 C.F.R. § 11.35
Equipment operational readiness
(a) EAS Participants are responsible for ensuring that EAS Encoders, EAS Decoders, Attention Signal generating and receiving equipment, and Intermediate Devices used as part of the EAS to decode and/or encode messages formatted in the EAS Protocol and/or the Common Alerting Protocol are installed so that the monitoring and transmitting functions are available during the times the stations and systems are in operation. Additionally, EAS Participants must determine the cause of any failure to receive the required tests or activations specified in § 11.61(a)(1) and (2). Appropriate entries indicating reasons why any tests were not received must be made in the broadcast station log as specified in §§ 73.1820 and 73.1840 of this chapter for all broadcast streams and cable system records as specified in §§ 76.1700, 76.1708, and 76.1711 of this chapter. All other EAS Participants must also keep records indicating reasons why any tests were not received and these records must be retained for two years, maintained at the EAS Participant's headquarters, and made available for public inspection upon reasonable request.
(b) If an EAS Encoder, EAS Decoder or Intermediary Device used as part of the EAS to decode and/or encode messages formatted in the EAS Protocol and/or the Common Alerting Protocol becomes defective, the EAS Participant may operate without the defective equipment pending its repair or replacement for 60 days without further FCC authority. Entries shall be made in the broadcast station log, cable system records, and records of other EAS Participants, as specified in paragraph (a) of this section, showing the date and time the equipment was removed and restored to service. For personnel training purposes, the required monthly test script must still be transmitted even though the equipment for generating the EAS message codes, Attention Signal and EOM code is not functioning.
(c) If repair or replacement of defective equipment is not completed within 60 days, an informal request shall be submitted to the Regional Director of the FCC field office serving the area in which the EAS Participant is located, or in the case of DBS and SDARS providers to the Regional Director of the FCC field office serving the area where their headquarters is located, for additional time to repair the defective equipment. This request must explain what steps have been taken to repair or replace the defective equipment, the alternative procedures being used while the defective equipment is out of service, and when the defective equipment will be repaired or replaced.
(d) EAS Participants shall employ the following security controls with respect to EAS equipment, studio transmitter link equipment, and any remotely managed equipment that routes, processes, or inserts content into the transmission of the EAS Participant's programming:
(1) Prior to any use to broadcast to the public, EAS Participants shall change any default password, use strong passwords, and change any password if the EAS Participant has reason to believe that the password has been compromised.
(i) A strong password is any password that has a minimum of 15 characters and does not use dictionary words. Instead of using a strong password, EAS Participants may use alternative authentication measures, such as look-up secrets, out-of-band devices, single- or multi-factor one-time password devices, or single- or multi-factor cryptographic authentication, that are reasonably sufficient to mitigate the risk of unauthorized access.
(ii) Passwords employed to comply with this requirement shall not be reused for the EAS Participant's other accounts, equipment, applications, or services.
(2) Install security patches and security-related software and firmware updates issued by equipment manufacturers promptly after those patches or upgrades become available. Security patches and security-related software and firmware updates issued by equipment manufacturers may be tested before they are installed, provided that the testing begins promptly and is completed in a timeframe that is consistent with industry best practices; and
(3) Use a network firewall or comparable network segmentation practice that limits remote management access to authorized devices and authorized users.
