    1. Is Palo Alto a stateful firewall?


      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?


      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?


      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?


      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?


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

    6. What is the zone protection profile?


      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?


      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?


      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?


      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?


      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?


      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?


      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?


      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?


      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?


      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 ?


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

       u-turn NAT
       u-turn NAT

      In above example, the website company.com ( statically NAT’ed with public IP address on untrusted zone. Users in the corporate office on the 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?


      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 through the public IP address from internet

       Destination NAT
      Destination NAT 

      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 ?


      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 ?


        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 ?


    • 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?


    • 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
    • request high-availablity state suspend : to suspend active box and make the current passive box as active

    23. What you mean by Device Group and Device Template?


      Device group

      Device group allows you to group firewalls which is require similar set of policy , such as firewalls that manage a group of branch offices or individual departments in a company. Panorama treats each group as a single unit when applying policies. A firewall can belong to only one device group. The Objects and Policies are only part of Device Group.

      Device Template :

      Device Templates enable you to deploy a common base configuration like Network and device specific settings to multiple firewalls that require similar settings. This is available in Device and Network tabs on Panorama

    24. Why you are using Security Profile?


      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

      Following are the Security Profiles available

    • Antivirus Profiles
    • Anti-Spyware Profiles
    • Vulnerability Protection Profiles
    • URL Filtering Profiles
    • Data Filtering Profiles

    25. What are the different states of HA Firewall?


      StateOccurs In Short Description
      InitialA/P or A/ATransient state of a firewall when it joins the HA pair.
      ActiveA/P State of the active firewall in an active/passive configuration.
      PassiveA/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.
      TentativeA/ACaused due to Failure of a firewall, Failure of a monitored object (a link or path), The firewall leaves suspended or non-functional state.
      Non-FunctionalA/P or A/AError state due to a dataplane failure or a configuration mismatch
      SuspendedA/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?


      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?


      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?


      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?


      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?


      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)?


      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?


      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 ?


      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.

      F5® VIPRION® platform (chassis) High-end VIPRION platform delivers decryption throughputs greater than 100 GB, providing the ability to aggregate and to manage an ever-increasing volume of network traffic. Modular design and clustering capabilities allow the VIPRION to easily scale as network needs evolve.

    52. What is Dynamic Service Chaining in Palo Alto?


      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?


      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?


      IT/OT integration is the end state sought by organizations (most commonly, asset-intensive organizations) where instead of a separation of IT and OT as technology areas with different areas of authority and responsibility, there is integrated process and information flow.

    55. Which is IT & OT convergence layer in the network?


      IT/OT convergence is the integration of IT systems with the operational technology (OT) systems traditionally used in industrial environments to monitor processes and devices. Put another way, IT/OT convergence is the introduction of a factory-wide IT network into the industrial environment.

    56. Why Use Palo Alto Networks With My Splunk?

    58. Why Use Splunk With My Palo Alto Networks Products?


      Palo Alto Networks products offer wonderful levels of visibility into community visitors and malicious hobby, each inside the network and at the endpoint. Combining this visibility with Splunk lets in a consumer to make correlations and carry out analytics around different types of facts. These correlations may be between specific types of Palo Alto Networks information, as an instance, correlating Wildfire reviews in opposition to site visitors logs to hit upon infected hosts, or correlating firewall logs with endpoint logs. But the actual energy of Splunk is correlations and analytics across multiple assets of records and a couple of vendors, as an instance, correlating firewall logs with webserver logs, or superior endpoint safety logs with Windows event logs.

    59. Does The App Conform To The Common Information Model?


      Yes! The Common Information Model (CIM) is a fixed of standards and an app that help other apps conform to a common naming and tagging scheme. This permits Splunk users to look for records throughout multiple styles of logs from more than one providers the use of the identical area names to get right of entry to the facts, which eases correlations across one-of-a-kind forms of records. For example, a Splunk consumer could correlate among firewall logs and web server logs. To Splunk for Palo Alto Networks app conforms strictly to the Common Information Model.

    76. What is a zero trust approach?


      Zero Trust is a strategic initiative that helps prevent successful data breaches by eliminating the concept of trust from an organization’s network architecture. Zero Trust is not about making a system trusted, but instead about eliminating trust.

    77. What capabilities are required to implement zero trust security?


      A Zero Trust solution requires operational capabilities that: Never trust, always verify – Treat every user, device, application/workload, and data flow as untrusted. Authenticate and explicitly authorize each to the least privilege required using dynamic security policies.

    78. What is Security Operating Platform?


      The Security Operating Platform empowers you to confidently automate threat identification and enforcement across cloud, network and endpoints – using a data-driven approach and precise analytics. It blocks exploits, ransomware, malware and fileless attacks to minimize infected endpoints and servers.

    79. What is the Framework of a Security Operating Platform?


      The Security Operating Platform empowers you to confidently automate threat identification and enforcement across cloud, network and endpoints – using a data-driven approach and precise analytics. It blocks exploits, ransomware, malware and fileless attacks to minimize infected endpoints and servers.

    80. What is IT OT Convergence?


      IT/OT convergence is the integration of information technology (IT) systems with operational technology (OT) systems. IT systems are used for data-centric computing; OT systems monitor events, processes and devices, and make adjustments in enterprise and industrial operations.

    81. What was there before Zero Trust Architecture?


      By taking advantage of micro-segmentation and granular perimeters of enforcement around your most critical data, Zero Trust combats the exfiltration of sensitive data and prevents threats from moving laterally within a network.

    82. Why do you need Static Analysis, Dynamic Analysis, and Machine Learning?


      Machine learning compensates for what dynamic and static analysis lack. A sample that is inert, doesn’t detonate, is crippled by a packer, has command and control down, or is not reliable can still be identified as malicious with machine learning.

      All federal agencies, departments and contractors are required to comply with FISMA standards (whether they are a cloud service provider or not), whereas FedRAMP is reserved only for agencies or cloud service providers who currently use or plan to use a cloud solution to host federal information.

    86. Why is 5G a security risk?


      With 5G, there are new and potentially greater security risks to consider as cloud, data and IoT threats merge. In fact, 32% of operators point to an increased attack surface as a key challenge here. The pandemic has only intensified these issues, especially the risk of ransomware-related breaches.

    87. What is PCI DSS means?


      The Payment Card Industry Data Security Standard (PCI DSS) is required by the contract for those handling cardholder data, whether you are a start-up or a global enterprise.

    88. What is a Pay Load based Signature?


      Payload-based signatures detect patterns in the content of the file rather than attributes, such as a hash, allowing them to identify and block altered malware. … With payload-based signatures, one signature can block tens of thousands of variants from the same malware family.

    90. What is the purpose of an IT security policy?


      In TypeScript, static typing means parameters, variables, and object members have types that compiler recognizes at the time of compile. This helps in detecting early errors faster than unit test runs. It also greatly helps IDEs with auto-completion and API exploration with statically typed DOM. Static typing is an important chapter which supports a number of TypeScript Interview Questions, so it’s crucial to practice this one.

    91. What is an Intrusion Prevention System?


      An intrusion prevention system (IPS) is a network security tool (which can be a hardware device or software) that continuously monitors a network for malicious activity and takes action to prevent it, including reporting, blocking, or dropping it, when it does occur.
