In the first article in this series, we discussed what zero trust security is and why it matters. In this article, we will take a deep dive into zero trust network access, how it works, and its benefits to the modern organization.
What Is Zero Trust Network Access?
Zero Trust Network Access, or ZTNA, is a security solution that many IT departments and IT organizations use to ensure secure remote access to a range of data, applications, networks, and services within an organization. ZTNA is based on defined access control policies that clearly communicate who has access to what and for how long that access is granted.
ZTNA is a gap-filler when it comes to secure remote access tools, methods, and technologies. VPNs or virtual private networks are different from zero trust network access because VPNs give access to an entire network rather than specific applications or data. As the remote workforce continues to take shape and many companies lean on it as a source of employee satisfaction and employer productivity. Zero trust network access is pertinent to keeping the right people in and the wrong people out of your organization’s systems.
How Does Zero Trust Network Access Work Continue reading
Zero Trust is a framework for security in which all users of an application, software, system, or network, inside or outside of an organization, must be authenticated, verified, and frequently validated before being granted access to specific data or tools within the company’s network. In the zero trust framework, networks can be in the cloud, hybrid, or on-premise with employees in any location. The assumption is that no users or devices are to be trusted with access without meeting the necessary validation requirements.
In today’s modern digital transformation forward environment, the zero-trust security framework helps to ensure infrastructure and data are kept safe, and more modern business challenges are handled appropriately. For example, as the pandemic has evolved, securing remote workers and their access will be of greater importance for organizations that want to scale their workforce. Ransomware threats and attacks are increasing, and zero trust implementation can detect these threats, from novel ones to custom-crafted malware, far before they cause harm.
What Foundation Makes up Zero Trust?
Zero Trust security is built on the architecture established by the National Institute of Standards & Technology (NIST). The
