Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Fail-safe and fail-secure are distinct concepts. Fail-safe means that a device will not endanger lives or property when it fails. Fail-secure, also called fail-closed, means that access or data will not fall into the wrong hands in a security failure. Sometimes the approaches suggest opposite solutions.
When used in PPP, CHAP also provides protection against replay attacks by the peer through the use of a challenge which is generated by the authenticator, which is typically a network access server. Where CHAP is used in other protocols, it may be sent in the clear, or it may be protected by a security layer such as Transport Layer Security (TLS).
A couple of new HAIPE devices will combine the functionality of a router and encryptor when HAIPE IS version 3.0 is approved. General Dynamics has completed its TACLANE version (KG-175R), which house both a red and a black Cisco router, and both ViaSat and L-3 Communications are coming out with a line of network encryptors at version 3.0 and above.
An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.

Network security is a umbrella term to describe security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1]
Network cloaking may provide more operational security through obscuring devices from hackers. To access a network behind a gateway, an authorized user must authenticate themselves to the gateway before it allows them to see the devices they are permitted to by the security policy. Network cloaking obscures devices through the cloaking system ...
In this diagram the router is a single point of failure for the communication network between computers. A single point of failure (SPOF) is a part of a system that would stop the entire system from working if it were to fail. [1]
