The PRISMA VelaSync uses smart reference monitoring to validate the fidelity of all available references. It does this by actively comparing phase offset of each reference against the primary reference and each other. The phase error validation calculates long-term averages and standard deviations of the phase offset between the monitored external reference and the internal system reference. The standard deviation is used to calculate two validity thresholds; a higher and a lower one (the latter acts as a hysteresis buffer, preventing the status flip/flopping if the actual phase error validation value varies closely around the outer threshold).
Security is a priority within the PRISMA VelaSync and included as part of the standard platform. Capabilities include supporting centralized authentication (LDAP, RADIUS, TACACS+), journaled activity logging, secure protocol support (SSH, HTTPS), and more. Updates are generally released on a quarterly basis, but patches and fixes to major CVE’s are addressed as they are discovered.
