Byron V. Acohido on The Last Watchdog blog provides a discussion of the Zero Trust approach to computer networks. “All of this evangelizing of a ‘never trust, always verify’ posture has incrementally gained converts among early-adopter enterprises,” he writes.
Acohido focuses on a visit he made to Portsys, “a US-based supplier of advanced identity and access management (IAM) systems (that) has been a vocal proponent of Zero Trust,” to provide his review.
These are complex matters that don’t yield to summarization. So we refer you to the blog post itself for study and digestion of an important area of computer security. Acohido is a Pulitizer Prize-winning business journalist.
