Sans today’s broadening horizons of technological reach, and the resulting dissolution of geographical boundaries, providing access to enterprise applications would have been a simplified process, given that all users would have resided in predictable locations, and would have used enterprise issued devices. However, with the advent of the cloud generation, access on the go has become paramount for the effective operation of any organization. This, in turn, creates multiple complexities, exposing the vulnerabilities that can be easily be exploited in traditional technologies like Virtual Private Networks. Essentially, enterprises using legacy-based VPN systems have to deal with higher risks of lateral movement attacks, a lack of device-level monitoring of access, and additional costs in deploying full VPN gateway application stacks while extending access to remote users.
The prospects associated with Zero Trust Architecture has thrown up a window of opportunity that has been suitably exploited with the introduction of a neoteric offering, Software Defined Perimeters. Contrary to the ineffectiveness, low scalability, and cost heavy nature of traditional network security constructs, Software Defined Perimeters provide a viable, scalable, highly productive alternative that secures your network infrastructure with greater accuracy.
With a view of upending cybersecurity infrastructures, SDPs serve to offer flexibility in security policies, in conjunction with granular level access control. As a result, SDPs significantly minimize the attack surface on offer, resulting in fewer exposable vulnerabilities in the network.
Operating on an ‘inherent distrust’ model, SDP’s dynamic and context-dependent trust validation system seeks to restrict access to resources based on credential policy thresholds. The SDP architecture further expands upon the “need to know” security model, providing additional layers of security like the Mutual Transport Layer Security. By extending protection beyond traditional perimeters with a hardware-free configuration, SDPs ensures that both the device and the user can access only what they are authorized to access. Further, SDPs endeavor to secure all critical resources by separating access control and data planes, thus rendering them invisible to external unauthorized users.
In essence, the following benefits may be derived from SDPs:
- Empowering digital transformation: SDP solutions ease your transition to the usage of transformative technologies like the Internet of Things (IoT), and cloud computing, with their scalability and cloud compatibility. Having been built on a connection based architecture, SDPs are specifically designed for scalability in today’s cloud environment.
- Granular level Analytics: SDPs effectively allow you to have a microscopic control on who has access to what, and through which device. Granular level monitoring and authentication processes take into account multiple sources of data and perform deep-dive analytics to garner new insights, along with greater visibility
- Reduced Attack Surface: SDPs significantly lessen the attack surface by blackening or rendering invisible the enterprise resources in the public network, effectively creating a nearly impenetrable intranet within the internet.
- Higher Flexibility: With its cloud-agnostic interface, SDP seamlessly functions with complete pliancy, enabling enterprises to migrate their workload to different cloud environments with ease.
- Simplified, Dynamic Operation: SDP provides a simple and dynamic alternative to existing security solutions, by incorporating an adaptive model that adjusts itself as per changes in an enterprise environment. With a hardware-free, zero-configuration model, it presents a simple, hassle-free substitute for complex traditional hardware-based solutions.
The ability to seamlessly integrate into existing security infrastructures, and authenticate and authorizing users continuously, with an adaptive deployment model that lays special emphasis on Continuous Diagnostics and Mitigation, makes SDPs a very viable alternative to existing security systems. The primary aim of the architecture is making access control as granular as possible, and at the same time, completely eradicating any form of unauthorized access.to enterprise resources.
InstaSafe combines the disparate needs of security and access of the digital worker into a single cloud-delivered scale-out platform, which can be deployed in minutes, and managed via intuitive policy-based management. It introduces a new software-defined, Zero Trust (ZTNA) architecture that uses a trusted broker to mediate connections between a specific private application and an authorized user. It allows teams to begin with zero trust, but then provide connectivity based on context (identity, device, etc.). Unlike VPNs, InstaSafe Secure Access delivers a means of application access without network access, and the ability to mask applications from the open internet.
