A Black Cloud may be coming to many cloud sites. A “Black Cloud” or “Software Defined Perimeter (SDP)” is a need-to-know security model. Infrastructure is hidden or “black” and does not reveal DNS or IP information.
Software Defined Perimeters are an alternative to traditional security tools like VPNs and firewalls. The problem is that more and more devices are gaining access to networks. Telecommuting, IoT, and connections from smartphone and tablet devices are making the management of incoming traffic difficult — the perimeter or attack surface of network is bigger and harder to manage.
In 2017, Gartner began predicting the demise of the traditional VPN. “By 2021, 60 percent of enterprises will phase out network VPNs for digital business communications in favor of software-defined perimeters.”
What are some of the advantages of SDP?
- Components of a network are hidden and can’t be uncovered using port scanning
- User certificates are not needed
- Access is direct. No physical or application access is needed.
Technavio predicts that the software defined perimeter market will grow 34 percent annually from 2019-2023.
Paul Campaniello, Chief Marketing Officer at Cryptzone, said that “SDP enables organizations to provide feasible and fast access to networked systems, services and applications while effectively reducing the attack surface by making servers invisible to bad actors. Indeed, one of the biggest advantages of Software-Defined Perimeter is that it overcomes the constraints of traditional tools and effectively creates a dynamic, individualized perimeter for each user.”
