How Are Zero Trust Architectures Evolving within SASE Solutions?​

John Kindervag from Forrester Research formulated the zero-trust security paradigm. The aim was to address the constraints of traditional perimeter-focused security strategies. Visible in the name, zero trust strives to eliminate implicit trust in an organization's security program. It is a security framework centered on never trusting, always verifying, and is undergoing exciting advancements within the SASE domain. Imagine a castle with drawbridges raised, guards verifying every entrant, and limited access based on individual permissions. That's the essence of Zero Trust. It assumes every entity (user, device, application) is untrusted by default and requires continuous verification before granting access to resources. This contrasts with traditional perimeter-based security, where trust is granted once inside the network. The zero trust approach includes the least privilege, continuous verification, and micro-segmentation. Users only get the minimum access needed for specific tasks. Identity, context, and device posture are constantly assessed. Networks are divided into smaller, secure zones with granular access control.

The integration of a SASE platform makes it possible for enterprises to consolidate SWGs, DLP, DNS layer protection, SD-WAN, and other features into a single platform. All of the actions taken to secure the edge are reasonable and warranted. While SASE does not imply zero trust, establishing zero trust is fundamental to SASE. Zero trust is a philosophy, a journey, a progression, an evolution. Differentiating the methodology from the product is necessary. Most SASE systems do an outstanding job of establishing a zero-trust architecture. However, it is critical to note that installing SASE does not mean your journey to zero trust is complete.

It's important to consider that the foundational principle of zero trust isn't just about stopping potential threats. It's about mitigating the damage caused by infiltration. Implementing micro-segmentation, identity and access management, patching, and sandboxing are additional ways to improve your zero-trust maturity. Numerous incidents disclosed in industry and national news could have been prevented with a zero-trust strategy. SASE solutions are consistent with zero trust and can assist with containment. Consider solutions from vendors that back their performance claims with references, statistics, and third-party tests and efficacy reports.

SASE serves as a powerful platform for implementing and expanding Zero Trust principles. SASE's Contribution to Zero Trust Evolution includes the following features:

  • Identity-driven access: SASE works with identity and access management solutions to help users authenticate and authorize before allowing access to apps.
  • Dynamic context awareness: SASE uses contextual data such as the location of the user, type of the device, and program activity to make better access decisions.
  • Enhanced security services: Built-in security features like ZTNA, CASB, and SWG further strengthen data protection and threat prevention within the Zero Trust framework.
  • Micro-segmentation capabilities: SASE solutions often offer network segmentation functionalities, enabling organizations to create secure zones with distinct access policies.
  • Cloud-based enforcement: By centrally managing security and access control in the cloud, SASE simplifies zero-trust implementation across diverse environments.

Evolving Zero Trust within SASE:

  • AI and machine learning (ML): Integrating AI and ML into SASE platforms enables proactive threat detection, anomaly analysis, and real-time risk assessment, further refining Zero Trust access control.
  • User experience focus: Simplifying authentication processes and context-aware access control enhances user experience within the Zero Trust framework.
  • Granular policy management: Granular policy controls tailored to specific applications, users, and devices provide even more precise access control within the Zero Trust model.
  • Expanding SASE capabilities: Continued integration of security tools like DLP and FWaaS within SASE offerings further strengthens the Zero Trust architecture.

The most important distinction between Zero Trust and SASE is coverage. Zero Trust offers an approach to managing access and permission controls for authenticated users. In contrast, SASE is larger and more sophisticated. SASE provides extensive security and network services, including Zero Trust. The two frameworks differ in how they manage user identity and access.

What Is the State of SASE Integration with Edge Computing Technologies?​

Edge computing is a distributed computing platform that connects enterprise applications to data sources like IoT devices or local edge servers. This proximity to data at its source can deliver strong business benefits, including faster insights, improved response times, and better bandwidth availability. Factories, warehouses, hospitals, retail stores, windmills, and first-responder vehicles make up the network's farthest reaches. These are the locations where computing is done locally rather than in a cloud or data center. This proximity allows for quicker data processing and less latency, making it ideal for real-time applications. These locations have always produced a lot of data, mainly from IoT devices. The emerging difference is that now the data is not only created at the edge but also processed at the edge. Organizations are pulling back from the cloud-first mentality and asking instead how they can use all this data at the edge to make faster and smarter decisions or create new customer experiences. More than half of enterprise-managed data will be created and processed outside the data center, at the edge, by 2026.

Edge computing and SASE combine to reinvent industry standards, particularly in retail, manufacturing, and emergency services. SASE design protects and optimizes vast data streams from the edge. It enables smarter, faster, and more secure operations across these vital sectors. Edge computing can be incorporated into a wide variety of applications, products, and services listed below:

  • Security systems: The motion sensor computation is moved to the network edge instead of a cloud server. Each camera has its own internal computer to run the motion-detecting application and then send footage to the cloud server as needed. This would result in a significant reduction in bandwidth use, and the server could communicate with a higher number of cameras without lag.
  • IoT devices: Smart devices that connect to the Internet can benefit from running code on the device itself, rather than in the cloud, for more efficient user interactions.
  • Self-driving cars: Autonomous vehicles must react in real time, without seeking directions from a server.
  • Better caching: By running code on a CDN edge network, an application can customize how content is cached to more efficiently serve content to users.
  • Medical devices: It is crucial for medical devices to respond in real-time without waiting to hear from a cloud server.
  • Video conferencing: Interactive broadcasting requires a great deal of bandwidth, therefore relocating backend functions closer to the video source can reduce lag and latency.

The future of SASE and edge computing integration is promising with standardization efforts, advanced edge security features, and simplified SASE management. Industry collaboration is driving the development of standardized protocols and APIs for easier integration and interoperability. SASE vendors are incorporating edge-specific security features like container security and workload protection for comprehensive protection at the edge. Centralized SASE platforms will offer unified management of edge devices and applications, simplifying security operations.
