Zero Trust Solutions

Never trust, always verify with a Zero Trust security model

In this era of evolving business models, shifting workforce dynamics, cloud adoption, and increased device and connectivity complexity, many organizations are prioritizing the adoption of the Zero Trust security model. A Zero Trust strategy for cybersecurity provides the opportunity to create a more robust and resilient posture, simplify security management, improve end-user experience, and enable modern IT practices. Zero Trust by Deloitte offers a broad range of advisory, implementation, and managed services to help organizations align to the ‘never trust, always verify’ cyber approach while securing the ubiquitous nature of their modern enterprises.

Zero Trust Access

Deloitte’s Zero Trust Access service (ZTA) can help accelerate an organizations’ adoption of Zero Trust by securely connecting what matters most: users to applications. The service is designed to help businesses address the evolving requirements of enterprises to confidently protect their applications, infrastructure and data. It offers a cloud-native service that secures communications between end user devices, and enterprise applications, wherever they may reside. Deloitte’s Zero Trust Access can replace legacy remote access technology with a modern Deloitte managed service or complement a broader ecosystem of technologies and capabilities to accelerate Zero Trust adoption.

With innovative microcontainer-based data protection, the Zero Trust Access service enables organizations to protect sensitive information, prevent data exfiltration, and potentially replace costly and complex legacy solutions. The service provides a turnkey solution that accelerates Zero Trust connectivity with application segmentation and inherent data protection capabilities – relieving IT and security teams of the cost and complexity that’s typically associated with deploying and maintaining a myriad of security controls to achieve similar outcomes.

Zero Trust Network Access (ZTNA)

Software defined perimeter (SDP) architecture, coupled with application segmentation capabilities, removes the need to provision inbound network access to sensitive resources. Connecting users directly to target applications vs. broad network access prevents lateral movement risks by making the underlying networks inaccessible to the user.

Built-in Data Protection

Data at-rest, in-use, and in-transit is secured through strong encryption, configurable control over print/copy/paste features, anti-keylogging, anti-screen scraping, watermarking, remote data destruction, and other built-in data protection features.

Continuous Authorization

Authorization is continuously re-examined after initial access and can be dynamically adjusted based on contextual security information such as device security posture, location, time of day, and device integrity.

Ephemeral Connectivity

The cloud component brokers each connection and tears it down upon session completion. Peer-to-peer (P2P) communication between the end user and target application allows for data traffic to flow directly between the source and destination, rather than traversing third party environments - virtually eliminating man-in-the-middle threats.

Deloitte’s Zero Trust framework

A Zero Trust model is built upon strong foundational capabilities across five fundamental pillars: identities, workloads, data, networks, and devices.

A Zero Trust Fundamentals

A Zero Trust strategy brings with it a set of design principles that guide security architecture development and build on existing security investments and processes. To enforce access control, companies need to have situational awareness of their data and assets; companies that lag on basic cyber hygiene principles and practices may be challenged to realize the full benefits of Zero Trust. Fundamentals may include:

Benefits of a Zero Trust security model

A Zero Trust architecture may help overcome common challenges of traditional cybersecurity approaches by leveraging new capabilities and opportunities to close gaps and become more agile and efficient. Potential benefits of Zero Trust include:

The fully integrated, dynamic approach under Zero Trust can protect the organization regardless of where connections originate. This makes the organization more difficult to target than one whose infrastructure is easily identified by adversaries.

When users, devices, resources, and their related data are identified and isolated, intrusions that may occur can similarly be isolated to prevent lateral movement and limit the potential blast radius. Such an environment requires a high degree of automation and orchestration, resulting in a more secure, resilient, and integrated environment. This compares with a traditional, perimeter-centric approach to security where layered but siloed defenses can be pierced to expose the internal environment and potentially put the entire organization at catastrophic risk.

Analytics such as anomalous detection, machine learning, AI, and real-time data inventory and cataloging can enable organizations to gain broader, real-time visibility into their threat landscape. This deployment of active defense technologies can overcome the limited visibility that is common in organizations which identify threats only as they hit the perimeter.

Organizations can anticipate adversary movements and initiate pre-emptive action more proactively than with traditional defenses, which are more reactive in nature.
