How Zero Trust Network Access (ZTNA) is evolving for enterprise network security

In an increasingly complex world of cybersecurity, Zero Trust Network Access (ZTNA) is growing in popularity. This technology offers a more secure approach to managing access to networks and applications. The principle of cybersecurity is based on the principle of “trust no one.” In contrast to traditional security models that assume that all devices within an internal network are secure, ZTNA requires every user and device to be rigorously authenticated and authorized before being granted access to network resources, regardless of location.

Differences between ZTNA and Traditional Security Systems Traditional security systems often rely on firewalls to protect the network perimeter. Therefore, ZTNA adopts a “trust no one” approach to be more effective in countering threats from within the network. ZTNA is able to limit access and network segmentation so that it limits access permissions according to needs. That way, the risk of misuse of access and cyber attacks can be minimized.

Why is it important to implement ZTNA?

  • Shifting Work Landscape: With more employees working remotely and the widespread use of cloud computing, traditional network perimeters are becoming increasingly sparse.
  • Ever-Increasing Cyber ​​Threats: Cyber ​​attacks are becoming increasingly sophisticated and often start with compromise of user credentials. ZTNA helps reduce this risk by continuously verifying user and device identity.
  • Strict Regulations: Many industries have strict compliance requirements regarding data protection. ZTNA can help organizations meet these requirements by providing an additional layer of security.

How does ZTNA work?

  • Identity Verification: Every user and device must go through a strong authentication process before being granted access.
  • Policy-Based Authorization: Access to network resources is restricted based on strict policies, which consider factors such as user location, devices used, and access times.
  • Encryption: All network traffic is encrypted to protect data from eavesdropping.
  • Needs-Based Access Control: Access can be granted based on user or device attributes, such as role, group, or security status.

Benefits of Using ZTNA in corporate networks

  • Better Security: ZTNA provides better protection against cyber threats by reducing the attack surface and limiting access to sensitive data.
  • Better Visibility: ZTNA provides better visibility of user and device activity on the network.
  • Easier Compliance: ZTNA can help organizations meet stringent compliance requirements.
  • Better User Experience: ZTNA can provide a better user experience by enabling faster and more secure access to needed applications and data.

The ZTNA concept can be implemented as a separate solution or can be implemented as part of a SASE solution. ZTNA is included in the SASE components, along with Software-Defined Wide Area Network (SD-WAN), Cloud Access Security Broker (CASB), and Secure Web Gateway [SWG]. One of the advantages of implementing this system is simpler network security management for optimal network performance.

ZTNA in SASE Key to Security in the Digital Era

In the digital industry era, data security has become a top priority, especially as data protection becomes increasingly complex. Secure Access Service Edge (SASE) is the right solution. As one of SASE’s features, Zero Trust Network Access (ZTNA) is based on the principle that nothing should be implicitly trusted, neither users nor devices. Every action will go through a continuous Authentication-Authorization, and Audit process.

This verification process is not only based on user identity but also on other factors such as location, device used, and user behavior. So ZTNA acts as an enabler of access control in Secure Access Service Edge (SASE) over static company policies to become more dynamic, policy-based, and tailored to needs.

What are the benefits of ZTNA in SASE?
  • Higher Security Level: By verifying every connection, ZTNA reduces the risk of cyber attacks such as hacking and malware.
  • Flexibility: ZTNA allows secure access to applications from anywhere, supporting a more flexible work style.
  • Easier Management: On some brands, ZTNA can be integrated with a broader SASE platform, making network security management easier.
  • Comprehensive Cloud Protection: ZTNA provides extra cloud-based protection, and its packages can be customized per user as needed.

 

For example, an employee wants to access company financial data from their personal laptop. With ZTNA, the system will verify the employee’s identity, check the security status of their device, and ensure that they only have access to the necessary data.

ZTNA is an important component of SASE that provides an additional layer of security for organizations. By adopting ZTNA, you can protect your company’s IT infrastructure from increasingly sophisticated cyber threats and ensure that your business runs smoothly.

The ZTNA concept can be implemented as a separate solution or can be implemented as part of a SASE solution. ZTNA is included in the SASE components, along with Software-Defined Wide Area Network (SD-WAN), Cloud Access Security Broker (CASB), and Secure Web Gateway [SWG].

Zero Trust Network Access: A Reliable Network Security

The increasingly flexible work environment with many employees working from anywhere has opened doors for hackers. As physical office boundaries become increasingly blurred, traditional defenses become vulnerable. Zero Trust Network Access (ZTNA) emerges as a modern defense fortress that never lets down its guard. Every access to company data, no matter where it comes from, is always strictly verified. With ZTNA, you can sleep soundly without worrying about your company data falling into the wrong hands. But what is ZTNA? What are the benefits of using ZTNA? Let’s explore further.

 

 

Zero Trust Network Access Definition

Zero Trust Network Access (ZTNA) is a security approach that treats all users and devices as potential threats. Unlike traditional network security, which trusts everyone inside a network, ZTNA verifies each user and device before granting access to company resources. This “never trust, always verify” principle helps protect against cyberattacks.

The traditional “castle and moat” security model, where a strong external defense protects everything inside, is no longer effective. With data spread across different locations, including cloud platforms, securing an entire network is challenging. ZTNA offers a more robust solution by continuously verifying access, reducing the risk of data breaches. As remote work becomes common, ZTNA is essential for safeguarding company information.

 

 

What are the Main Principles Behind Zero Trust Network Access?

Continuous Verification

Zero trust assumes that threats can come from both inside and outside the network. Therefore, it constantly checks and confirms the identity and security of users, devices, and connections. Logins and connections time out periodically once established, forcing users and devices to be continuously re-verified.

 

Least Privilege

This principle means giving users only the absolute minimum access they need to do their job. It’s like providing soldiers with only the information they must know, limiting each user’s exposure to sensitive parts of the network and their potential to cause damage.

 

Strict Device Control

Zero trust carefully monitors and controls which devices can access the network. It ensures all devices are authorized and free from security risks to protect the entire network. This further minimizes the attack surface of the network.

 

Microsegmentation

To enhance security, Zero trust divides networks into small, isolated segments. This prevents unauthorized access to sensitive data. For example, a network might have dozens of separate, secure zones. Access to each zone requires specific permission, preventing intruders from moving freely within the network.

 

Preventing Lateral Movement

Lateral movement happens when attackers move from one part of a compromised network to another. Zero trust stops this by creating isolated network segments. If an attacker gains access to one segment, they can’t easily spread to others. This makes it easier to identify and contain the threat.

 

Multi-Factor Authentication (MFA)

Zero trust emphasizes strong authentication. This means requiring multiple forms of identification, not just a password. For instance, users might need to enter a password and a code sent to their phone. This extra layer of security makes it harder for unauthorized individuals to gain access.

 

 

Benefits of Zero Trust Network Access

Secure Remote Access

ZTNA provides a secure method to connect users, applications, and data regardless of their physical location. This is crucial in today’s complex IT environments where applications and data are often spread across multiple cloud platforms and on-premises infrastructure.

 

Flexible and Secure Access

Modern businesses require their digital resources to be accessible from anywhere, at any time, and on any device. ZTNA delivers this flexibility while maintaining robust security by granting access to specific applications based on user identity, location, and other relevant factors.

 

Reduced Security Risk

ZTNA helps to mitigate security risks by limiting access to only what is necessary. Unlike traditional network security models that grant broad access, ZTNA adopts a “zero trust” approach, verifying user identity and device trust continuously. This prevents unauthorized access and protects sensitive data.

 

 

How to Implement Zero Trust Network Access?

There are two primary methods for setting up ZTNA: a standalone system or a cloud-based service.

Standalone ZTNA involves building and managing the entire ZTNA infrastructure within your organization. This approach suits companies that prefer to avoid cloud services. However, it requires significant effort to set up, maintain, and manage the system.

ZTNA as a Service relies on a cloud provider to handle the ZTNA platform. Your company only needs to purchase user licenses and install connectors on your applications. The cloud provider takes care of network connections, system capacity, and overall infrastructure. This option simplifies management and often provides faster network speeds.
