By https://interview.quicktechie.com/tenants/ Section: NGFW and SASE Solution Functionality — 18 Percent This section focuses on understanding the key functionalities of Next-Generation Firewalls (NGFW) and Secure Access Service Edge (SASE) solutions from Palo Alto Networks. As organizations move to hybrid and cloud-first architectures, it becomes critical to know how firewall series, SD-WAN, and cloud components work together to secure the modern enterprise. Let’s explore each topic in detail. 2.1 Explain the Function of Cloud NGFWs, PA-Series, CN-Series, and VM-Series Firewalls Palo Alto Networks offers multiple firewall series to cover diverse deployment needs. Each of these solutions is designed to provide consistent security across physical, virtual, and cloud environments. 2.1.1 Perimeter and Core Security PA-Series and CN-Series firewalls protect both the perimeter and the core of the network. Perimeter security deals with external threats, while core security focuses on protecting internal assets from lateral movement. The VM-Series and Cloud NGFWs extend this functionality into virtualized environments and public clouds like AWS and Azure. Cloud NGFW offers managed firewall-as-a-service, eliminating the need to manage infrastructure while retaining full inspection capabilities. 2.1.2 Zone Security and Segmentation Firewalls create zones to segment network traffic based on trust levels. For example, you can define Trust, Untrust, DMZ, and Guest zones. Policies are written between zones, which improves security and control. Segmentation also helps enforce the principle of least privilege, ensuring only necessary communication occurs between applications and users. By https://interview.quicktechie.com/tenants/
