Q: What is the difference between a Palo Alto Networks firewall and a traditional firewall?
Ans:
Palo Alto Networks firewalls give you visibility into and control over users, content, and applications at the application layer. Standard firewalls can't recognize apps; they usually function at the network layer.
Q: How does Palo Alto Networks prevent threats using Threat Prevention?
Ans:
Palo Alto Networks uses vulnerability protection, antivirus software, and anti-spyware to identify and stop known and new threats. It makes use of WildFire as well for effective threat analysis.
Q: What is WildFire, and how does it contribute to threat prevention?
Ans:
Palo Alto Networks offers a cloud-based threat analysis service called WildFire. It checks unidentified files for malware and exploits and offers threat intelligence that security policy updates can use.
Q: Explain the concept of App-ID in Palo Alto Networks?
Ans:
Palo Alto Networks firewalls provide a feature called App-ID that allows it to recognize and manage apps irrespective of their protocol, port, or defensive techniques. It includes a variety of techniques, such as behavioral analysis, algorithms, and signature matching.

Q: Explain the function of the Palo Alto Networks URL Filtering feature?
Ans:
URL categories are used by URL filtering to regulate website access. By keeping users off of harmful or inappropriate websites, it improves security and complies with regulations.
Q: What is User-ID, and how does it enhance security?
Ans:
By linking user identities to network behavior, User-ID enables policies to be created based on groups and people as opposed to only IP addresses. Granular control and visibility into user-specific activities are made possible, which improves security.
Q: How does SSL Decryption work in Palo Alto Networks?
Ans:
The firewall can inspect and manage encrypted traffic through SSL decryption. Before forwarding SSL/TLS traffic, it decrypts it, verifies its security, and then re-encrypts it.
Q: What is Panorama, and how does it simplify firewall management?
Ans:
Palo Alto Networks uses Panorama as its central management tool. It simplifies configuration, logging, and network monitoring by offering a single pane of glass for managing numerous firewalls.
Q: Explain the function of Security Policy in Palo Alto Networks?
Ans:
Palo Alto Networks Security Policy establishes the guidelines for permitting or prohibiting traffic depending on a number of factors, including source, destination, application, and user. It is essential to the implementation of security controls.
Q: What is the purpose of the Threat Landscape dashboard in Palo Alto Networks Panorama?
Ans:
A visual representation of the current danger landscape, comprising the most popular applications, threats, and URLs, may be found in Panorama's danger Landscape dashboard. It assists security teams in promptly recognizing and countering new threats.
Q: What is the difference between Threat Prevention and URL Filtering?
Ans:
Threat prevention uses techniques such as behavioral analysis and antivirus software to detect and stop both known and undiscovered threats. In contrast, URL filtering improves security and compliance by restricting access to websites based on their categories.
Q: Explain the purpose of the Palo Alto Networks Expedition tool?
Ans:
A tool called Expedition is intended to help users in converting firewall configurations from other vendors to Palo Alto Networks standard. It guarantees a seamless transition and expedites the migration process.
Q: How does Palo Alto Networks contribute to Zero Trust security principles?
Ans:
Palo Alto Networks supports zero trust by protecting and inspecting all traffic, independent of its source or destination, and by offering granular management depending on user and application.
Q: What is the purpose of GlobalProtect in Palo Alto Networks?
Ans:
Palo Alto Networks offers a VPN product called GlobalProtect. It extends the firewall's protection to distant places by giving users and devices safe remote access to the network.
Q: How does Palo Alto Networks support High Availability (HA) configurations?
Ans:
Palo Alto Networks offers capabilities such as Active/Passive and Active/Active modes that facilitate HA deployments. Continuous availability and failover in the event of hardware or software failure are guaranteed by HA.
