Edwards Cybersecurity

Edwards has a rigid cybersecurity protocol for EST4 fire alarm systems

As cybersecurity needs expand, Edwards EST4 provides solutions that can help meet the demands of a connected life safety system. Cybersecurity is essential, here are the ways Edwards keeps you protected:

  1. Email/SMS, ECPxml, web browser services are via 256 bit AES via SSL/TLS (FIPS-197)
  2. Email/SMS root certificates are from Mozilla Public License
  3. Central Station connections (IP dialer): 128 bit AES Tyco Protocol, encryption/authentication key provided by central station on an account by account basis
  4. Email/SMS and IP to a CMS are outgoing communication services only initiated by the EST4
  5. Browser and ECPxml communications are incoming communications using a passphrase for authentication within a TLSsession. ECP is hashed by port and requires a passphrase of up to 40 Unicode characters and a Hashed salted license key. The web browser session is authenticated by the rewall system, requiring a passphrase of up to 40 Unicode characters
  6. Web browser provides access only to system reporting functions, no update methods are provided
  7. 4-FWAL incoming service requests can be turned off at startup, by time of day or via programming, with only outgoing requests allowed. This rewall policy keeps system critical events always being able to be sent to services like central monitoring stations
  8. Session timeout is enforced
  9. Brute force access through the web browser shuts down after five unsuccessful authentication tries. These access attempts are stored to history as monitor events
  10. While the EST4 rewall works in tandem with the site IT infrastructure, the site should always include its own commercial rewall to protect the building network or intranet.
