A variety of recent trends have forced businesses to rethink their approach to data loss prevention. The accelerating shift to cloud, proliferation of SaaS applications and the shift to hybrid work all have resulted in businesses becoming more vulnerable to data breaches.

Traditional approaches to security, which trusted devices within a perimeter or firewall, or even those connected by a VPN are no longer relevant in these complex networks.

Data breaches are costing businesses more than ever. According to IBM’s Cost of a Data Breach 2022 Report, the average cost of a data breach in the ASEAN region was USD 2.87 million, rising from USD 2.71 million in 2021. There is a clear necessity for enterprises to make a radical shift in their data loss prevention strategy. One new approach to deal with data loss risk is Zero Trust security.

In fact, Zero Trust approach is also receiving support from various government bodies as they introduce compliance requirements for organizations to follow. In the US, a White House Executive Order specifically mandated zero trust approach as a best practice for modern cybersecurity programs across sectors. 

How Zero Trust Protects Enterprise Data

Zero Trust architecture relies on distinct techniques to be adopted across key pillars including those on the user end, at the application or data level and during transmission.

Protection from User Side

On the user side, zero trust goes beyond user and device identification. It has evolved to include integration with an Identity Access Management (IAM) system and authentication through Multi-factor authentication (MFA) and Single Sign-On (SSO).  Every device or user is authenticated and explicitly authorized using least privilege access control, so that only essential data that is under the user’s authority scope is given access.  The security of the user’s device is also checked to avoid cyberthreats.

Protection from Application/Data Side

At the level of the application or data, zero trust will eliminate the attack surface from the network and creates a safe zone for sensitive data. The connections will be directly from the user to the app or between apps, which helps eliminate lateral movement within the network and prevents compromised devices from infecting other resources. With users and apps being invisible to the network, they can’t be discovered or attacked. Additionally, data loss protection features work to prevent cases of screenshot, printing, copy and paste, file transmission and may even generate watermark. 

Protection from Data Transmission

In zero trust architecture, a number of techniques are used for protecting data on the transmission side, such as mutual TLS or MTLS, HTTPS, IPsec and data loss protection.  

A HTTPS tunnel is also used to create a secure connection between the connector and user client. It could also be used to create a secure connection between two or more devices on a network.  mTLS is a method for mutual authentication and ensures that users at the end of a network connection both have the correct private key. The TLS certificates of each party at the end will also have information for additional verification. 

IPsec is a set of protocols that provides security for Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. Data loss prevention involves a set of processes and tools that are designed to protect sensitive data in organizations from unauthorized access.

Why Use CDNetworks for Your Zero Trust Architecture?

CDNetworks understands the importance of Zero Trust Architecture in today’s enterprises. With this need in mind, we offer Enterprise Secure Access (ESA), a cloud service that provides enterprises with secure remote access. ESA incorporates all the essential techniques needed for establishing zero trust access, and much more, so you can continue using cloud-based applications while following hybrid working environments.

ESA is implemented with a Software-Defined Perimeter(SDP) infrastructure which lets you enforce zero trust policies to and from any platform in any environment on any device. With ESA, you also get to take advantage of CDNetworks’ globally distributed DDoS-resistant edge network to accelerate remote access and provide users with speedy and secure access to applications. It’s easy-to-manage platform also means you can set up and maintain applications and users individually and in batches, while visualized reports and alerts give you insights for intelligent decision making.
