Default Shut vs. Default Open Systems

Default Open Systems

A default open system protects its territory starting from the outside. For example, using Firewalls, Permimeter defence mechanisms and ACLs is an open system practice.

Default Shut Systems

A default shut system protects its teritorry starting from the inside. For example, using PKC (publick key cryptography) and end-to-end encrypted software is a shut system practice.

tiCrypt is a default shut system with capabilities to add hybrid security layers such as firewalls, VPNs, ACLs and others.
