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.
