Port numbers, protocols, and IP addresses are useful for network devices, but they tell you nothing about what is on your network. Detailed information about the applications, users, and content traversing your network empowers you to quickly determine any risks they pose and quickly respond.

Leveraging the rich context provided by Palo Alto Networks firewalls, our visualisation, analysis, and reporting tools let you quickly learn more about activity on your network and analyse incidents from a current or comparative perspective.

Watch this video to see how much could be visible on your network. It allows you to keep your finger on the pulse of what is going on. Knowledge is power. Learning more about new or unfamiliar applications or threats that are displayed in ACC takes just a single click, which shows you:. Integration with a wide range of directory services allows our system to display detailed user information along with their IP addresscomplementing the application and threat information you receive.

You can add additional filters to learn more about application usage for individual users, along with the threats detected within your application traffic. In only minutes, ACC arms you with the data you need to make more informed security policy decisions and take action to reduce risk in your enterprise. A standard feature in both our device web-interface and Panorama centralized managementApp-Scope reduces the amount of time you have to spend investigating unusual behaviour.

Our log viewer provides a fine-grain view into your network activity. It summarises all traffic traversing the network — including apps, user information, and threats. Logs can be sent automatically to your syslog server, while individual filter results are exportable to a CSV file for offline archival or further analysis. More than 50 predefined, customisable reports — incorporating elements you choose from other reports — are available. You can automate reports to run on a scheduled basis and have the results emailed or exported to a PDF or Excel spreadsheet.

Users: an integral component for secure application enablement policies. Traditionally, security policies were applied based on IP addresses, but the increasingly dynamic nature of users and applications mean that IP addresses alone have become ineffective as a policy control element for safe application enablement.

Our next-generation firewalls integrate with a wide range of enterprise directories and terminal services offerings, allowing you to:.

Visibility into the application activity at a user level, not just at an IP address level, allows you to determine patterns of usage along with the associated business and security risks. With just a few clicks, you will gain visibility into the application bandwidth and session consumption, the associated threats, as well as the source and destination of the application traffic.

With this knowledge, you can more proactively align application usage with your business unit requirements through safe application enablement policies. Visibility into application usage means that you can quickly analyse the role and risk of applications, and who is using them, then translate that information into user-based safe application enablement policies.

User-based policy controls can be assembled based on the application, which category and subcategory it belongs in, its underlying technology, or the application characteristics. Examples of user-based policies might include:. User information is pervasive throughout our firewall feature set — and that includes fine-grained forensic analysis and reporting.

You can easily create log filters by clicking on a cell value, which can then be expanded with additional criteria using the expression builder. Informative reports on user activities can be generated using any one of the many pre-defined reports, or by creating a custom report from scratch, or by modifying a pre-defined report.The internet has changed the way we live.

However, the internet also makes us susceptible to hackers, targeted advertisements and other privacy concerns. A virtual private network VPN allows you to safely connect to another network over the internet by encrypting the connection from your device.

A VPN makes your internet connection more secure and offers both privacy and anonymity online. Organizations, governments and businesses of all sizes use VPNs to secure remote connections to the internet for protection against malicious actors, malware and other cyberthreats. All information travelling from a device connected to a VPN will get encrypted and go through this tunnel.

The VPN will forward device traffic to and from the intended website or network through its secure connection. This allows remote users and offices to connect securely to a corporate network or website.

It also shields device IP addresses from hackers and prying eyes. Site-to-site VPN is used to connect branch offices to a central office over the internet when distance prevents direct network connections.

Remote access VPN allows individual users to remotely connect to a central network. In this case, the devices are referred to as endpoints. With a VPN, data traverses the internet through a secure tunneling protocol, where it is encrypted to stop any third party from reading your data as it travels. The two most popular network protocol suites for encryption are:. Essentially, encryption scrambles the contents of your information — making it unreadable — in a way that can only be unscrambled, or decrypted, using a key.

The tunneling protocol also encapsulates, or wraps, the data with routing information for the receiving user. Once received, the remote access connection is subject to an authentication, authorization and accounting AAA server program, which authenticates the user, authorizes access and accounts for all activity for the duration of the connection. For enterprises that operate multiple locations and access the cloud, a software-defined wide area network SD-WAN can offer many benefits above and beyond a VPN, including increased flexibility and agility to connect remote networks, improved user experience, and reduced costs.

By unifying the management of SD-WAN and security, enterprises can avoid leaving gaps in their security posture. This can also help maintain consistent security policies from the network core out to branches.

Source and Destination NAT Example

Faced with increasingly sophisticated, persistent cyberthreats, they wanted to tie in endpoint protection with their firewall. They got a full breadth of security capabilities at about half the cost by moving to Palo Alto Networks Next-Generation Firewall.In the previous installments of Getting Started, we covered how to set up the firewall from scratch.

In this next series, we'll be covering more advanced configuration features that will help you fine tune your firewall to better suit your environment. This week, we'll take a look at Layer 2 interfaces and how the firewall can be set up to provide bridging between VLANs while enforcing security policies and providing threat prevention to keep your network secure. We'll start with a simple example where we have two Layer 2 interfaces in the same zone and the same VLAN.

This configuration will ensure your hosts all remain on the same IP subnet, but can be segregated depending on their role. More interfaces can be added to provide even more segments or tagged subinterfaces can be added in a similar fashion as described in Getting Started: Layer 3 — Subinterfaces. You may have noticed some Layer 3-looking configuration in the VLAN configuration earlier, and this is where we will need to enable the functionality.

Any sessions originating from your internal hosts to the outside world will be handled by the firewall as coming from the Layer 3 Trust zone going to the Layer 3 Untrust zone. Please be aware you may need some additional configuration to allow for outbound connections, including the default route in your virtual router, NAT configuration so the internal IP subnet is translated to the public IP address of the firewall and maybe a DHCP server to automatically assign IP addresses to workstations joining your network.

I hope you enjoyed this article and found it useful. Feel free to post any remarks or questions in the comment section below. For more details on Layer 2 interfaces, please take a look at the Tech note on Layer 2 Networking. What more can my firewall do?

There will already be one default VLAN interface present, which you can reuse if you like, but we'll create a new one by clicking the Add button.

You'll assign the interface an ID, add any relevant comment and assign the interface to the default Virtual Router and add it to the Trust zone. Note that the ID is simply an identification number for the interface and does not influence any Simply give it a name and click OK for now.

The VLAN interface should look somewhat like this. Go ahead and click OK. This is because we have not yet created any Layer 2 Security Zones. Any Security Zone configured on the firewall is also attached to a specific network type, like Layer 3, VWire, or Layer 2. This is to allow traffic to pass from Layer 2 to Layer 3.

We'll take a look at that after we've completed this phase of the Layer 2 introduction. The last stage is to create an intrazone security policy to allow more granular control over applications connecting both segments and applying security profiles to these sessions.

Open the Policies tab and navigate to Security on the left pane. Click Add to create a new security policy. From the Rule Type dropdown, select 'intrazone' as the Type. Next, navigate to the Source tab, click Add, and set the source zone to L2-Trust. Because this is an intrazone Security Policy, the destination zone selection has been made inaccessible and is dependent on the source configuration. Set the applications to what is appropriate between the segments.Hence I am only showing the differences within the configuration and some listings from common CLI outputs for both firewalls.

The reason was some kind of differences within the IPsec tunnel handling between those two firewall vendors. Here are the details along with more than 20 screenshots and some CLI listings. Please note that I have many different VPN tutorials on my blog.

Have a look at this list to find the appropriate post. This one here focusses on IPv6 tunneling. I am using some uncommon but highly secure crypto protocols: ….Our previous article explained how Palo Alto Firewalls make use of Security Zones to process and enforce security policies.

This article will explain the different configuration options for physical Ethernet and logical interfaces available on the Palo Alto Firewall. Network segmentation becomes easier due to the flexibility offered by a single pair of Palo Alto appliances. Below is a list of the configuration options available for Ethernet physical interfaces:.

The various interface types offered by Palo Alto Networks Next-Generation Firewalls provide flexible deployment options. The advantage of this deployment model is that it allows organizations to closely monitor traffic to their servers or network without requiring any changes to the network infrastructure.

Tap mode offers visibility of application, user and content, however, we must be mindful that the firewall is unable to control the traffic as no security rules can be applied in this mode.

Tap mode simply offers visibility in the ACC tab of the dashboard. The catch here is to ensure that the tap interface is assigned to a security zone. The great thing about V-Wire deployment is that the firewall can be inserted into an existing topology without requiring any changes to the existing network topology.

The V-Wire deployment options overcome the limitations of TAP mode deploymentas engineers are able to monitor and control traffic traversing the link. In this mode switching is performed between two or more network segments as shown in the diagram below:.

Figure 3. In Layer 2 deployment mode the firewall is configured to perform switching between two or more network segments. Traffic traversing the firewall is examined, as per policies, providing increased security and visibility within the internal network.

In this mode the firewall interfaces are capable of supporting Access or Trunk Links Any BPDUs received on the firewall interfaces are directly forwarded to the neighboring Layer 2 switch without being processed. Layer 3 deployment mode is a popular deployment setup. In this mode the firewall routes traffic between multiple interfaces, each of which is configured with an IP address and security zone.

The Firewall interfaces can also be configured to obtain their IP address via a DHCP server and can be used to manage the security appliance. The diagram above shows a typical Layer 3 deployment setup where the Firewall routes and controls traffic between three different IP networks. Similar to other setup methods, all traffic traversing the Firewall is examined and allowed or blocked according to the security policies configured. In this article we examined a few of the different deployment modes available for Palo Alto firewalls.

Each deployment method is used to satisfy different security requirements and allows flexible configuration options. Visit our Palo Alto Firewalls Section for more in-depth technical articles.

Palo Alto Firewall Configuration Options. Tap Mode, VirPalo Alto Networks Next-Generation Firewalls rely on the concept of security zones in order to apply security policies. Palo Alto Networks Next-Generation Firewalls zones have no dependency on their physical location and they may reside in any location within the enterprise network.

This is also illustrated in the network security diagram below:. Figure 1. Palo Alto Firewall Security Zones can contain networks in different locations.

When aggregation interface ae1. Creating a Security Zone involves tasks such as naming the zone, assigning the interfaces to the new zone created and more. The diagram below depicts the order in which packets are processed by the Palo Alto Firewall:.

Figure 2. It is without doubt Zone based firewalls provide greater flexibility in security design and are also considered easier to administer and maintain especially in large scale network deployments. Figure 3. Palo Alto Networks Next-Generation Firewalls have special zone called External which is used to pass traffic between Virtual Systems vsys configured on the same firewall appliance.

The External zone type is only available in the Palo Alto Networks Next-Generation Firewalls which are capable of Virtual Systems and also the External Zone is visible only when the multi-vsys feature is enabled. Step 1.

Step 2. Step 3. Provide the name for the new Zoneand select the zone type and click OK :. In a similar manner we can repeat steps 1 to 3 to create TapVirtual Wire or Layer 2 security zones. Finally it is important to note that the zone names is case sensitive, so one needs to be careful as the zone FiewallCX and firewallcx are considered different zones:. Figure 6.

Identically named Security zones using different letter cases result in different Security zones.
