1. Is Palo Alto a stateful firewall?

Ans:

The answer would be yes because here all the firewall traffic can be transmitted through the Palo Alto system, and later these are matches against a session. More importantly, each session should match against a firewall cybersecurity policy as well.

2. What is the purpose of Palo Alto Focus?

Ans:

Palo Alto Focus is one of the services available in Palo Alto to identify the critical attacks and take necessary action without using any additional resources. It is considered as the cloud-based threat intelligence service.

3. Name the types of deployment modes in Palo Alto?

Ans:

There are four deployment models available such as;

Tap mode: this mode allows users to monitor any type of traffic flow across the networking system with the help of tap or switch SPAN/mirror port.

Virtual wire: in this deployment model, the firewall system is installed passively on any network segment by combing two interfaces together.

Layer 2 mode: in this layer mode, multiple networking interfaces will be configured into a “virtual-switch” or VLAN mode.

Layer 3 deployment: In this layer 3 deployments, the Palo Alto firewall routes allow traffic between multiple interfaces. User should add the IP address to each interface.

4. What are the scenarios for failover triggering?

Ans:

The following are the scenarios that explain the failure over triggering,

Failure occurs, if one or more monitored interface fail.

Failure occurs, if one or more specified destinations cannot be pinged by the active firewall.

If the active device does not respond to heartbeat polls or loss of three consecutive heartbeats over a period of 1000 millisecond this time failure occurs.

5. Which command is used to check the firewall policy matching in Palo Alto?

Ans:

Open the Palo Alto web browser -> go to test security -> policy -> match from trust to untrust destination.

6. What is the zone protection profile?

Ans:

With the help of the Zone protection profile, you will get complete protection from attacks like floods, reconnaissance, and packet-based attacks. The flood attacks can be of type SYN, ICMP, and UDP, etc. The reconnaissance protections will help you to defend against port and host sweeps. The packet protections help you to get the protection from the large ICMP and ICMP fragment attacks.

7.Name the types of protections used in Palo Alto?

Ans:

The following are the major protections used in Palo Alto;

Zone protection profile: examples are floods, reconnaissance, and packet-based attacks.

Configured under Network tab protection: Network profiles, and zone protections.

8. Mention the advantages of the Palo Alto firewall?

Ans:

The following are the important features of the Palo Alto firewall;

• Offers high throughput and low latency
• Palo Alto provides high-level active security functions
• Supports the provision of single and fully integrated security policy
• Easier to use management policy.

9. Define WAF and its purpose?

Ans:

WAF refers to the Web Application Firewall. The primary purpose of WAF is to monitor web applications to enhance the security and its features in web applications. It protects the web application by filtering the traffic between the internet and the application.

10. What is APP-ID?

Ans:

The built-in data types are also known as primitive data types in Typescript. These are given below.

App-ID is nothing but the short form for the application identifications. This is one of the main components in Palo Alto. The major responsibilities of App-Id included are identifying the applications and transverse the firewalls independently.

11. What are Active/passive and Active/Active modes in Palo Alto?

Ans:

There are many modes that can be used in Palo Alto configuration.

Active/passive: This mode in Palo Alto is supported in deployment types including virtual wire, layer2, and layer3. In this mode, the configuration settings are shared by both the firewalls. In this case, the active firewalls fail, the passive firewall becomes active and maintain network security.

Active/Active: This mode in Palo Alto is supported in deployment types including virtual wire and layer 3. In this mode, both the firewalls work synchronously and process the traffic.

12. What is an HSCI port?

Ans:

SCI is a layer 1 of the SFP+ interface. In an HA configuration, this connects any two PA -200 firewall series. This port can be used for both HA2 and HA3 network connections and the raw layer can be transmitted to the HSCI ports.

13. What are HA1 and HA2 in Palo Alto?

Ans:

HA1 and HA2 in Palo Alto have dedicated HA ports. HA1 port is a control link whereas HA2 is just a data link. These links are primarily used to synchronize the data and also help to maintain the state information.

14. What is incomplete and application override in palo Alto?

Ans:

Application Incomplete can be interpreted as-either the three-way TCP handshake is not completed or completed, and there was no information to classify the process just after handshake.Where as Application override is being used to bypass the App-ID (Normal Application Identification) for unique traffic transmitted via a firewall.

15. What is Single-pass parallel processing?

Ans:

Single-pass parallel processing allows the system to operate on one packet. The following are important features of Single-pass parallel processing such as policy lookup, identifying applications, performing networking functions, decoding, and signature matching. The content in the Palo Alto firewall is scanned only once in the architecture.

16. What is u-turn NAT and how to configure ?

Ans:

U-turn NAT is applicable when internal resources on trust zone need to access DMZ resources using public IP addresses of Untrust zone.



In above example, the website company.com (192.168.10.20) statically NAT’ed with public IP address 81.23.7.22 on untrusted zone. Users in the corporate office on the 192.168.1.0/24 segment need to access the company webpage. Their DNS lookup will resolve to the public IP in the Internet zone. The basic destination NAT rules that provide internet users access to the web server will not work for internal users browsing to the public IP.

17. How to publish internal website to internet. Or how to perform destination NAT?

Ans:

To publish internal website to outside world, we would require destination NAT and policy configuration. NAT require converting internal private IP address in to external public IP address. Firewall policy need to enable access to internal server on http service from outside .We can see how to perform NAT and policy configuration with respect to following scenario

Provide the access to 192.168.10.100 through the public IP address 64.10.11.10 from internet



Following NAT and policy rules need to be created. NAT:-> Here we need to use pre-NAT configuration to identify zone. Both source and destination Zone should be Untrust-L3 as source and destination address part of un trust zone.

18. Explain about various links used to establish HA or HA introduction ?

Ans:

PA firewall use HA links to synchronize data and maintain state information. Some models of the firewall have dedicated HA ports—Control link (HA1) and Data link (HA2), while others require you to use the in-band ports as HA links.

Control Link : The HA1 links used to exchange hellos, heartbeats, and HA state information, and management plane sync for routing, User-ID information and synchronize configuration . The HA1 should be layer 3 interface which require an IP address.

Data Link : The HA2 link is used to synchronize sessions, forwarding tables, IPSec security associations and ARP tables between firewalls in an HA pair. The HA 2 is a layer 2 link.

Backup Links: Provide redundancy for the HA1 and the HA2 links. In-band ports are used as backup links for both HA1 and HA2. The HA backup links IP address must be on different subnet from primary HA links.

Packet-Forwarding Link: In addition to the HA1 and HA2 links, an active/active deployment also requires a dedicated HA3 link. The firewalls use this link for forwarding packets to the peer during session setup and asymmetric traffic flow.

19. What are the Various port numbers used in HA ?

Ans:

HA1: tcp/28769,tcp/28260 for clear text communication ,tcp/28 for encrypted communication
HA2: Use protocol number 99 or UDP-29281

20. What are the scenarios for fail-over triggering ?

Ans:

• if one or more monitored interfaces fail
• if one or more specified destinations cannot be pinged by the active firewall
• if the active device does not respond to heartbeat polls (Loss of three consecutive heartbeats over period of 1000 milliseconds)

21. How to troubleshoot HA using CLI?

Ans:

• show high-availability state : Show the HA state of the firewall
• show high-availability state-synchronization: to check sync status
• show high-availability path-monitoring : to show the status of path monitoring

25. What are the different states of HA Firewall?

Ans:

State	Occurs In	Short Description
Initial	A/P or A/A	Transient state of a firewall when it joins the HA pair.
Active	A/P	State of the active firewall in an active/passive configuration.
Passive	A/P	The passive firewall is synchronizing flow state, runtime objects, and configuration.The passive firewall is monitoring the status of the active firewall using the hello protocol.
Active Primary	A/A	In an active/active configuration, state of the firewall that connects to User-ID agents, runs DHCP server and DHCP relay, and matches NAT and PBF rules with the Device ID of the active-primary firewall. A firewall in this state can own sessions and set up sessions.
Active Secondary	A/A	In an active/active configuration, state of the firewall that connects to User-ID agents, runs DHCP server, and matches NAT and PBF rules with the Device ID of the active-secondary firewall. A firewall in active-secondary state does not support DHCP relay. A firewall in this state can own sessions and set up sessions.
Tentative	A/A	Caused due to Failure of a firewall, Failure of a monitored object (a link or path), The firewall leaves suspended or non-functional state.
Non-Functional	A/P or A/A	Error state due to a dataplane failure or a configuration mismatch
Suspended	A/P or A/A	The device is disabled so won’t pass data traffic and although HA communications still occur, the device doesn’t participate in the HA election process. It can’t move to an HA functional state without user intervention.

26. What is a service route? What interface is used by default to access external services?

Ans:

The firewall uses the management (MGT) interface by default to access external services, such as DNS servers, external authentication servers, Palo Alto Networks services such as software, URL updates, licenses and AutoFocus

27. What is bootstrapping in Firewall?

Ans:

Bootstrapping speeds up the process of configuring and licensing the firewall to make it operational on the network with or without Internet access.

28. A traffic log displays “incomplete” for a new application. What does that mean?

Ans:

Incomplete means that either the three-way TCP handshake did not complete OR the three-way TCP handshake did complete but there was no enough data after the handshake to identify the application. In other words that traffic being seen is not really an application.

29. How Does Panorama address new logs Logs when It Reaches Maximum Storage limit?

Ans:

When log storage reaches the maximum capacity, Panorama automatically deletes older logs to create space for new ones.

30. What is the Captive portal and its usage?

Ans:

The Captive Portal is used to create a user-to-IP mappings on the Palo Alto Networks firewall. The portal is triggered based on the Captive Portal policies for http and/or https traffic only and is triggered only for the IP addresses without existing user-to-IP mapping.

31. What is the flow logic of the Next-Generation Firewall (Palo Alto)?

Ans:

Palo Alto Networks Next-Generation Firewalls works with the concepts of zones not interfaces, once a packet enters the firewall, the Palo Alto Networks Next-Generation Firewalls identifies from which zone the packet came and where it is destined to go. This is similar to Cisco IOS Routers Zone-based Firewalls and Cisco ASA Firewalls.

34. Why you are using Security Profile?

Ans:

Security Profile using to scans allowed applications for threats, such as viruses, malware, spyware, and DDOS attacks. Security profiles are not used in the match criteria of a traffic flow. The security profile is applied to scan traffic after the application or category is allowed by the security policy. You can add security profiles that are commonly applied together to a Security Profile Group.

35. What You Mean By Zone Protection Profile and GUI configuration ?

Ans:

Zone Protection Profiles offer protection against most common flood, reconnaissance, and other packet-based attacks. For each security zone, you can define a zone protection profile that specifies how the security gateway responds to attacks from that zone.

The following types of protection are supported:—-

Flood Protection— Protects against SYN, ICMP, UDP, and other IP-based flooding attacks.

Reconnaissance detection—Allows you to detect and block commonly used port scans and IP address sweeps that attackers run to find potential attack targets.

Packet-based attack protection—Protects against large ICMP packets and ICMP fragment attacks.

Network tab -> Network Profiles -> Zone protection.

52. What is Dynamic Service Chaining in Palo Alto?

Ans:

A typical security stack often consists of multiple systems such as a NGFW, intrusion detection or prevention systems (IDS/IPS), data loss prevention, and malware analysis tools. All these systems require access to decrypted data for inspection. SSL Orchestrator easily integrates with existing security architectures and centralizes SSL/TLS decryption across multiple inspection devices in the security stack. This “decrypt once and steer to many inspecting devices” design addresses latency, complexity, and risk issues that can occur if every single security device performs decryption. You can also create multiple service chains for different traffic flows using the context engine.

53. What is Health Monitoring?

Ans:

SSL Orchestrator provides various monitors to check the health of the security devices in a service and handles any failures instantly. For example, in a Palo Alto service, should a NGFW fail, the SSL Orchestrator system will shift the load automatically to the active NGFWs. If all the firewalls in the service were to fail, SSL Orchestrator would bypass the service to maintain network continuity and maximize uptime.

54. What is IT and OT integration?
