Zero trust is an IT security approach towards keeping sensitive data safe while staying compliant to new privacy regulations. As the use of cloud services rapidly expands, it also creates new potential for compromised or stolen credentials of a privileged administrator or application. Additionally, it can open the potential for data theft, and cyber criminals to conduct cyber fraud, as effective security controls are often an afterthought. Zero trust makes it possible for organizations to regulate access to systems, networks, and data without giving up control. Therefore, the number of organizations that are moving to a zero-trust security model (meaning trusting nobody) is growing, so that companies can safeguard data with security controls that restrict access to the data according to a specific policy.
A standard network security posture is focused on stopping threats that come from outside the network perimeter, but can leave data vulnerable to theft inside the network. This approach utilizes firewalls, VPNs, access controls, IDS, IPS, SIEMs, and email gateways with security on the perimeter that cyber criminals now know how to breach. This means someone with the correct credentials could be admitted to any network’s sites, apps, or devices. With zero-trust security, no one is trusted by default from inside or outside the network. Zero trust operates from the start by requiring verification from every user trying to gain access to resources, thereby authenticating users and regulating access to systems, networks, and data. This process involves validating user identities, associated access rights to a particular system, and enables organizations to manage the digital identities of users ensuring the appropriate access. To strengthen authentication, zero trust also uses several layers of advanced access control for access to network devices and the servers that support resources. This approach also enables the ability to track user activities, create reports on those activities, and enforce policies to ensure compliance.
The principles of zero-trust architecture as established by the National Institute of Standards & Technology (NIST) are:
Reduce risks from constant threats with security-first design principles. Use technologies such as built-in tenant isolation and least privilege access also helping with compliance and privacy regulations. With well-managed identities, organizations enable greater control over user access, which translates to reduced risks of internal and external breaches.
A zero-trust security approach involves capturing user information, managing user identities, and orchestrating access privileges to help with regulating access to systems or networks for individual users within an organization.
Enhance organizations’ security posture
Sharpen competitive edge
Organizations that adjust from a standard perimeter security approach to a zero-trust model take advantage of automation, security, and governance, which enhances their overall competitive advantage and business agility.
Organizations that pursue a zero-trust security model must:
An effective zero-trust security model will deliver:
- Isolated network virtualization
- Granular separation of duties
- Least privilege access
- Automated threat mitigation and remediation
- Default-enabled, ubiquitous encryption
- Continuous monitoring of user behaviors
- Context aware adaptive authentication
