Many organizations encounter difficulties when attempting to merge their existing security frameworks with zero-trust network access (ZTNA) solutions. While ZTNA can enhance the security and adaptability of a distributed workforce, its integration often presents challenges, particularly when it conflicts with legacy systems and established security protocols.
To start, security teams must consider the current infrastructure, identify potential friction points, and ensure a smooth user experience when incorporating ZTNA. Fortunately, new tools and methodologies are emerging that simplify this process, allowing companies to reap the benefits of ZTNA without compromising their existing security measures.
To help you smoothly integrate ZTNA into your cybersecurity strategy, here are some best practices for successfully implementing ZTNA using your current security infrastructure.
Why Should Businesses Adopt ZTNA?
With the increasing prevalence of cyber threats, the need for robust cybersecurity measures has never been more critical. Recent data reveals that in 2023, 82% of cloud breaches involved data stored in cloud environments.
In response, many businesses are turning to a zero-trust approach to network security. For instance, nearly 40% of financial institutions report extensive use of zero-trust networks, leading to significant cost savings. On average, these organizations save $850,000 by adopting zero-trust principles.
The financial advantages of ZTNA go beyond direct savings. Studies indicate that zero-trust strategies can reduce the overall cost of a data breach by approximately $1 million, as they allow for quicker identification and containment of breaches, minimizing the impact and costs associated with remediation, legal fees, and regulatory fines.
In addition to financial benefits, ZTNA provides a security framework that addresses the unique challenges of today’s distributed and cloud-based business environments. By verifying the identity, device, and context of every user and device before granting access, ZTNA significantly reduces the risk of unauthorized access, data theft, and other cyber threats.
Top Use Cases for ZTNA
ZTNA excels in managing remote access, striking a balance between the flexibility of remote work and maintaining network security. It enables users to access specific applications without granting unrestricted access to the entire network, thereby improving performance by directly connecting users to hosted resources. This approach alleviates internal bandwidth issues and ensures that access to applications is restricted until proper authentication is achieved.
Furthermore, ZTNA offers advantages over traditional VPNs and MPLS systems. Unlike MPLS, which requires expensive hardware, or VPNs, which may grant overly broad access, ZTNA simplifies network management and provides controlled access to cloud resources.
ZTNA also enhances internal network isolation. By adopting a least-privilege access model, it limits exposure to internal resources, granting users only the necessary permissions for their roles. This approach significantly reduces the potential damage from data breaches by restricting the amount of accessible and exploitable data.
Implementing ZTNA in Your Company
The first step in implementing ZTNA is identifying the “Protect Surface”—the most critical Data, Applications, Assets, and Services (DAAS) that require the highest level of security. Instead of mapping out the entire network, which is challenging due to its constant expansion, focus on pinpointing these key elements.
Next, analyze and document how specific applications interact within your network. This understanding will help you determine where to apply access controls and security measures, even if you don’t have full visibility across the entire system.
As you outline the “Protect Surface,” you can begin defining your zero-trust architecture, incorporating security measures that limit access to critical areas of your network.
Employ the Kipling Method—asking “Who? What? When? Where? Why? How?”—to establish the criteria for trustworthy access to protected areas. Ensure that all user-application communication is known and approved by your administrators.
Ongoing documentation of activity within your environment is equally important. This data enables administrators to strengthen your zero-trust security by refining access permissions over time. Continuous monitoring is essential to the effectiveness of your zero-trust strategy.
Choosing the Right ZTNA Provider
When selecting a ZTNA provider, consider factors such as flexibility, scalability, and ease of use. The ideal ZTNA solution should integrate seamlessly with your existing security infrastructure and provide robust features without compromising performance or user experience.
Look for providers that offer strong authentication, device trust verification, and granular access controls. Compliance features and reporting capabilities are also crucial to meet regulatory requirements. The right ZTNA solution will be adaptable to your organization’s needs, easy to manage, and capable of enhancing your overall security.
By carefully evaluating these factors, you can choose a ZTNA solution that aligns with your goals and lays the foundation for a successful zero-trust implementation, ensuring your organization is well-prepared to navigate the evolving cybersecurity landscape.
