Can you explain what NetCloud SASE with clientless Zero Trust Network Access (ZTNA) is and how it differs from traditional client-based ZTNA?

NetCloud SASE with clientless ZTNA is a security solution that allows organizations to grant secure access to their network without requiring a software client on the user’s device. Unlike traditional client-based ZTNA, which necessitates the installation and maintenance of client software, the clientless approach simplifies access by enabling users to connect through a secure URL. This eliminates the challenges of managing software on every device, making it ideal for dynamic environments with various types of devices and users.

How does the clientless ZTNA feature improve the security of organizations that need to connect third-party and BYOD users?

The clientless ZTNA feature enhances security by implementing advanced isolation technology. When third-party and BYOD users connect to the network, their application sessions are handled in isolated cloud containers. This creates an air-gap that prevents any potential malware on unmanaged devices from spreading to corporate systems. It ensures that even if a device is compromised, the threat is contained within the isolated environment and cannot affect the enterprise’s critical resources.

What motivated Ericsson to develop a clientless ZTNA solution specifically for dynamic, wireless-first environments?

Ericsson recognized the increasing trend of businesses adopting wireless-first strategies, particularly with the rise of 5G technology. These dynamic environments often include a mix of managed and unmanaged devices, making it challenging to ensure secure access.

By developing a clientless ZTNA solution, Ericsson aimed to offer a more flexible, easy-to-deploy security measure that caters to the needs of modern, wireless-centric organizations.

How does the isolation technology in NetCloud SASE enhance protection against third-party cyber incidents?

The isolation technology in NetCloud SASE operates by detaching application sessions from corporate networks. When third-party users access company resources, their sessions are processed in isolated cloud containers. This means that any malicious activity is confined within the container, preventing it from reaching the core network. This containment strategy significantly mitigates the risk of cyber incidents that often arise from third-party accesses, such as malware infections or data breaches.

How do isolated cloud containers work to secure application sessions for unmanaged or BYOD device access?

Isolated cloud containers function by creating a virtual environment that is completely separate from the main network. When a user from an unmanaged or BYOD device connects to the network, their session is contained within this isolated space. Any interactions, data transmissions, or potential threats are restricted to the container, ensuring that no adverse effects spill over into the corporate network. This prevents vulnerabilities from personal devices from compromising enterprise security.

What are the main advantages of using clientless secure access compared to traditional VPNs, clients, or special browsers?

Clientless secure access offers several significant advantages. First, it streamlines deployment since there is no need to install and maintain software on each user’s device. This reduces the workload on IT teams. Additionally, by utilizing a secure URL for access, it simplifies the user experience. It also mitigates risks associated with software vulnerabilities and outdated clients, providing a robust security posture that adapts to varying device types and user contexts.

Can you explain the steps involved for a contractor or BYOD user to access isolated applications via a secure URL?

For a contractor or BYOD user to access isolated applications, the process is straightforward. Upon receiving authorized credentials, the user navigates to a secure URL provided by the organization. They log in using their credentials, and once authenticated, their sessions are initiated within isolated cloud containers. This secure environment ensures that their access is both limited to necessary resources and is executed in a manner that protects the core network from any potential security threats.

How does NetCloud SASE protect IoT/OT assets and corporate applications from potential malware infections?

NetCloud SASE safeguards IoT/OT assets and corporate applications by employing an isolation-first approach. By channeling interactions through isolated containers, it ensures that any malware from unmanaged user devices does not infiltrate the core network. This containment strategy is particularly crucial for IoT/OT assets, which can be vulnerable entry points for cyber attacks. By isolating these interactions, NetCloud SASE effectively shields these critical systems from potential malware infections.

In what ways does granular access based on least privilege improve security?

Granular access based on least privilege significantly fortifies security by ensuring that users only have access to the minimum resources necessary for their tasks. This approach limits the potential for unauthorized access or misuse of information. By implementing role-based policies, organizations can tailor access levels appropriately, reducing the risk of insider threats and minimizing the attack surface, thereby maintaining a stronger security posture overall.

How does Ericsson’s ZTNA continuously assess risk and revoke access in response to changes in user context and risk levels?

Ericsson’s ZTNA leverages real-time analytics and intrusion detection/prevention systems to continuously monitor user activity and context. If the system detects any anomalies or heightened risk levels, it can promptly revoke access to prevent potential security breaches. This dynamic assessment allows for immediate responses to emerging threats, ensuring that the network remains secure even as user contexts or behaviors change.

Can you describe the “zero-trust” architecture used in NetCloud SASE and its key security features?

The zero-trust architecture of NetCloud SASE is predicated on the principle of “never trust, always verify.” This model eliminates the need for static public IP addresses and hides all internal IPs, preventing unauthorized access. Every access request is subject to scrutiny, requiring verification before granting entry. Key features include micro-segmentation to prevent lateral movement inside the network, default-deny policies, and continuous risk assessments to adapt to real-time threats and vulnerabilities.

How does the removal of static public IP addresses and hiding all internal IPs contribute to network security?

Removing static public IP addresses and concealing internal IPs significantly enhances network security by reducing exposure to external threats. Without static IP addresses, it becomes much harder for attackers to locate and target specific devices within the network. Hiding internal IPs adds another layer of security, minimizing the risk of unauthorized access and making it more challenging for potential attackers to map or break into the network.

What role does micro-segmentation play in preventing lateral movement within the network?

Micro-segmentation divides the network into smaller, isolated segments, each with its own access controls and policies. This division ensures that if an attacker breaches one segment, they cannot easily move laterally to other parts of the network. By limiting movement, micro-segmentation helps contain threats and minimizes the potential damage from a security breach.

How does the integrated management platform in NetCloud Manager simplify deployment, visibility, and policy enforcement?
