In today’s world of growing technology, network infrastructure is constantly changing. It adopts hybrid and multi-cloud architecture for providing flexibility, scalability, and redundancy. But they also face their own challenges, while securing access to resources and users across various cloud environments. Zero Trust Network Access (ZTNA) provides secure connectivity in diverse and complex infrastructures. Tata Communications provides Zero Trust Network Access that has become important nowadays in India for cloud-native applications which verifies every request, user, and workload.
In this blog, let us learn about ZTNA in multi-cloud environments: ensuring consistent security across platforms.
Why Is ZTNA Important In A Multi-Cloud Environment?
Where traditional network security systems fail to manage the dynamic nature of multi-cloud architecture, Zero Trust Networking Access comes into action in securing multi-cloud environments.
How ZTNA Ensures Consistent Security Across Platforms?
- Seamless Integration Across Cloud Providers:
ZTNA provides seamless integration and networking across multiple cloud environments like AWS, GCP, Oracle Cloud, and Azure.
- Advanced Identity And Access Management:
It integrates with leading IAM solutions and provides strict access controls based on Zero Trust principles.
- Multi-Factor Authentication (MFA):
It requires multi-level verification to authenticate users.
- Role-Based Access Control (RBAC):
It enables users to have the permissions only for the necessary things to perform their tasks.
- Contextual Access Control:
It evaluates the major factors such as user location, device health, and behavioural patterns to provide or deny access.
- Micro-segmentation:
It supports micro-segmentation and allows enterprises to create individual segments within their multi-cloud networks. It prevents the possible risks of security breaches associated with a specific segment and prevents lateral movement.
- Automated Compliance Management:
It streamlines compliance management across various multi-cloud environments. It provides automated tools for
- Policy Enforcement:
It ensures constant security policies across all cloud environments.
- Audit Trails:
It manages detailed logins and reports for compliance audits.
- Security Posture Management:
It regularly monitors and tests the security of multi-cloud environments to find and resolve possible issues.
What Are The Core Principles Of Zero Trust?
Zero Trust Networking Access works on the following core principles.
- Continuous Verification:
It validates and authenticates every user and device regularly.
- Least Privilege Access:
It provides minimal access that is necessary for users to perform their tasks.
- Micro-Segmentation:
It breaks down network perimeters into smaller zones to check the possibility of potential breaches and limit lateral movement.
- Assume Breach:
It functions with the assumption that the network already has been compromised, ensuring quick response and containment strategies.
What Are The Advantages Of ZTNA?
Zero Trust Network Access provides multiple benefits to enterprises.
- Working From Home:
ZTNA helps to manage remote workers or work-from-home officials. Zero Trust Network Access simplifies deployment and enrollment processes which would have consumed your time and money with traditional VPN methods. This one is a transparent and simpler security measure for remote working environments.
- Application Micro-Segmentation:
ZTNA also provides application security with micro-segmentation, the integration of device health into access policies, constant authentication and verification. It also reduces the implicit trust and the lateral movement associated with VPN.
- Stopping Ransomware:
ZTNA also reduces the chances of Ransomware or other network-based attacks.
- On-board New Applications And Users Quickly:
ZTNA ensures better security and flexibility in quickly changing environments where users come and go. This also helps to install new applications securely and quickly, easily accept or deny users and devices, and give analysis for usage and status of applications.
Final Thoughts
In the world of improved technology, cyber threats are increasing rapidly and are becoming more advanced. Zero Trust Network Access not only helps to protect your remote working system but it is also a necessary option in providing better security and improving your business growth.
