Zero Trust Security

A key concept of zero trust security is that it assess security dynamically.

Zero Trust Network (ZTN)

Zero Trust Architecture (ZTA)

Zero Trust Network Access (ZTNA) is an IT security solution that provides secure remote access to an organization’s applications, data, and services based on clearly defined access control policies.

It may substitute a VPN and provide access not to all internal resources as default, but only to those the endpoint need access.

Service Access Service Edge (SASE) controls access to application regardless the location or users involved.

SASE may make use of Software-Defined WAN (SD-WAN).

Zero Trust is achieved through these elements (not extensible list):

  • NAC
  • Microsegmentation
