Introduction
The zero trust network access (ZTNA) architecture was designed for today’s business environment. It is intended to reduce the attack surface of a company’s digital networks and to prevent unauthorized users from accessing these networks. ZTNA, a deliverable from numerous technology and security businesses, takes a person-centric approach to network authentication and authorization.
What Is Zero-Trust Network Access?
ZTNA is a cybersecurity architecture that operates on the premise that no one can be trusted and that all resources, including systems and applications, must be verified and approved. It takes a person-centric approach that is based on identity and authorization rules. It is built on the three concepts of least privilege, least effort, and least exposure, which means that only those who require access to their unique resources are permitted access.
By preventing unauthorized users from accessing resources, the architecture serves to reduce the attack surface of a company’s digital networks. ZTNA aids in the protection of data and resources from potential threats both inside and outside the network. It accomplishes this by utilizing role-based access management, multi-factor authentication, and device posture verification.
ZTNA is a product offered by several technology and security firms, including Microsoft, Google, Symantec, and Sailpoint. The Zero Trust Model from Microsoft is built on four critical components: authentication, endpoint security, identity and access management, and data privacy and protection.
Related Events
As ZTNA is a rapidly expanding technology field, there are numerous connected events and conferences. The Zero Trust Accelerator and the Zero Trust Leadership Summit are two examples. The Zero Trust Accelerator is a two-day virtual event aimed to hasten the transition of traditional networks that require some level of trust to a zero trust architecture. The Zero Trust Network Alliance (ZTNA) is hosting the event. The Zero Trust Leadership Summit is an annual conference to discuss and advance the ZTNA, as well as to establish an open, vendor-neutral international network of ZTNA professionals.
Qualifications and Education
ZTNA is associated with several credentials and training courses. These include the Zero Trust Network Alliance (ZTNA) Zero Trust Network Certificate, the Institute for Network Security (INS) Certified Zero Trust Network Security Analyst, and the Information Systems Audit and Control Association (ISACA) Zero Trust Network Security (ZTNS) certification. These certifications are intended to provide organizations confidence in Zero Trust Network Access thinking and best practices.
The expansion of ZTNA
As enterprises strive to protect their networks and applications from cyber threats, the need for Zero Trust Network Access is growing. In 2018, the global Zero Trust Network Access market was worth around USD 10.48 billion, and it is expected to increase at a compound yearly growth rate of 24.2% from 2019 to 2025. The growing need for identity and access management (IAM) solutions, as well as the necessity for enhanced security solutions, are propelling the market forward.
Conclusion
Zero trust network access (ZTNA) is a cybersecurity architecture that helps safeguard an organization’s digital networks by reducing the attack surface and preventing unauthorized individuals from accessing them. Multiple technological and security businesses, including Microsoft, Google, Symantec, and Sailpoint, are delivering the technology. There are numerous ZTNA-related events, conferences, qualifications, and training available, and the demand for this sort of architecture is increasing as enterprises appreciate the significance of securing their networks and applications from cyber threats.
