In this article Digital transformation is shaping a new normal. Organizations are embracing digital transformation to manage continuous business environment changes by tracking: • Shifting business models and partnerships. • Technology trends. • Regulatory, geopolitical, and cultural forces. Additionally, COVID-19 remote work accelerated this transformation and is shifting security from a cost center to a strategic driver for growth. Zero Trust is security for digital business. Digital transformation requires updating traditional security models because traditional security approaches don’t meet current requirements for business agility, user experiences, and continuously evolving threats. Organizations are implementing Zero Trust to address these challenges and enable the new normal of working anywhere, with anyone, at any time. However, shifting from a traditional security model to Zero Trust represents a significant transformation that requires buy-in, adoption, and change management across an entire organization. Updating a traditional security model to Zero Trust is a transformation that takes time and requires buy-in, adoption, and change management across an entire organization. Business leaders, technology leaders, security leaders, and security practitioners all play critical parts in creating an agile Zero Trust security approach. Many security architects and IT teams ask for help communicating to business leaders, tracking progress, and driving adoption. This gu...

There’s no shortage of definitions of , which describes the following seven tenets of zero trust. 1. All data sources and computing services are considered resources Gone are the days of considering only endpoint user devices or servers as resources. Networks today consist of a dynamic array of devices from traditional items such as servers and endpoints to more dynamic cloud computing services such as , which may execute with specific permissions to other resources in your environment. For all data and computing resources in your environment you must ensure you have basic, and when warranted, advanced authentication controls in place as well as least-permissive access controls. Feeding into subsequent tenets, all these resources are communicating to some extent and can provide signal context to help drive decisions made by the architectural components in zero trust, which are discussed in tenet 7. 2. All communication is secured regardless of network location In zero trust environments, the concept of In a ZTNA environment, the access policy instead is a default-to-deny. Explicit access must be granted to specific resources. Furthermore, users operating in ZTNA environments won’t even have awareness of applications and services within environments without those explicit grants of access existing. It is hard to pivot to something you aren’t aware exists. Today’s geographically dispersed workforce, further exacerbated by the COVID pandemic has made tenet 2 even more critica...

/ What Is Zero Trust? What Is Zero Trust? Zero trust is a framework for securing organizations in the cloud and mobile world that asserts that no user or application should be trusted by default. Following a key zero trust principle, least-privileged access, trust is established based on context (e.g., user identity and location, the security posture of the endpoint, the app or service being requested) with policy checks at each step. Zero Trust Architecture Explained Zero trust is a cybersecurity strategy wherein security policy is applied based on context established through least-privileged access controls and strict user authentication—not assumed trust. A well-tuned zero trust architecture leads to simpler network infrastructure, a better user experience, and improved cyberthreat defense. A zero trust architecture follows the maxim "never trust, always verify." This guiding principle has been in place since John Kindervag, then at Forrester Research, coined the term. A zero trust architecture enforces access policies based on context—including the user's role and location, their device, and the data they are requesting—to block inappropriate access and lateral movement throughout an environment. Establishing a zero trust architecture requires visibility and control over the environment's users and traffic, including that which is encrypted; monitoring and verification of traffic between parts of the environment; and strong multifactor authentication (MFA) methods beyo...

The perimeter-based model considers users, devices and resources residing directly on the corporate LAN and WAN as more trustworthy than those from outside the network. The But making the switch to a zero-trust model requires logistical considerations and planning. To help with the migration from a perimeter-based security architecture to a zero-trust framework, many organizations have referred to the Forrester Zero Trust eXtended (ZTX) model to help. ZTX has become a go-to reference on how to best purchase and implement the right tools, policies and methodologies. 7 pillars of the zero-trust model The Forrester zero-trust framework breaks down seven necessary pillars to 1. Workforce security The workforce security pillar centers around the use of security tools such as 2. Device security Much like workforce security, the primary goal of the device security pillar is identification and authorization when devices attempt to connect to enterprise resources. The devices may be user-controlled or completely autonomous, as in the case of IoT devices. 3. Workload security The workload security pillar refers to the applications, digital processes, and public and private IT resources used by an organization for operational purposes. Security is wrapped around each workload to prevent data collection, unauthorized access or tampering with sensitive apps and services. 4. Network security The network security zero-trust pillar is used to help 5. Data security This zero-trust pillar r...
