Enterprise technology has changed. Work habits have changed. And the network perimeter has dissolved.
Network security must change to keep up with enterprise technology and work habits. This is causing a fundamental shift in network security. The difference is:
Network Access Control (NAC) Trusts Users Inherently
This trust model is designed to work inside the perimeter, yet Forrester says it is broken for four reasons:
- It's impossible to identify trusted interfaces
- The mantra "trust but verify" is inadequate
- Malicious insiders are often in positions of trust
- Trust doesn't apply to packets
Software-Defined Perimeter (SDP) Trusts No One
Abolishing the idea of a trusted network inside (or outside) the corporate perimeter.
NAC was designed to work inside the perimeter – Build a perimeter around the internal network, verify who users say they are, and once in the door users gain full access to the network or at least a large portion of the network. But in this changing world, NAC falls short for seven reasons.
In our eBook, How to Overcome NAC Limitations: Why a Software-Defined Perimeter delivers better network security for today’s enterprises, we discuss the reasons NAC solutions fail to protect your network and why a Software-Defined Perimeter overcomes these limitations.
This eBook is for security, network, IT architect, operations, infrastructure and GRC professionals who want to protect access to physical, virtual and cloud-based IT systems.
