Why is Zero Trust security model critical?
In enterprises, network security through perimeter security evolved over time to avoid external attacks from the network intruders. This evolution includes new network security protocols, encryptions and authentication algorithms and methods to protect against malware, hacking and identity theft.
Improving productivity through “always-connected” technologies, enterprise mobility architecture, cloud applications for collaboration, and BYOD for enterprise access has posed additional challenges to enterprises to enhance their security architecture.
- Device Loss/Theft
- Unsecured Mobile apps
- Access/Authorization controls
Therefore, enterprises are migrating from perimeter to perimeter less security architecture (Zero Trust Model for securing Network & Application access) without impacting their “always-available” mobility enabled application architecture.
What is Zero Trust
Enforces enterprise to not trust network perimeters and verify anything and everything that tries to connect to applications and systems before granting them access. The Zero Trust Security model moves access control mechanisms from the network perimeter to the actual users, devices and systems.
Zero Trust emphasizes robust user authentication and device validation over network and endpoint security as key to protecting applications and data against new and emergent threats. Instead of having enforcement mechanisms at the network perimeter, zero trust focuses on moving them as close as possible to the actual application or surface that needs to be protected.
The Zero Trust security model relies on existing technologies such as multi-factor authentication (MFA), analytics, encryption, micro-segmentation & granular perimeter enforcements and applies them based on the users, their location and other data to determine whether to trust user, machine or application seeking access to a particular part of the enterprise. It includes compliance processes to accomplish its mission of securing the enterprise environment (i.e., networks, application & systems) by governing the policies to restrict a user with contained access to accomplish a specific task.
