When implementing active-active high availability (HA), a floating IP address must be configured to allow the HA pair to share a single IP address that may be used as the network's gateway IP address. This floating IP address ensures that either of the active-active firewalls can assume control of the traffic without interruption in case of a failover.

Intrusion Prevention System (IPS):The CN-Series firewalls incorporate an Intrusion Prevention System to detect and prevent exploits and attacks on applications and systems. This feature is essential for securing east-west traffic, as it can identify and block threats within the data center traffic between pods in different trust zones.

Layer 7 Visibility:CN-Series firewalls provide Layer 7 (application layer) visibility, enabling deep inspection of application traffic. This allows the firewall to understand and enforce policies based on the application and its behavior, rather than just ports and protocols, ensuring comprehensive security for east-west traffic within a Kubernetes environment.

CN-Series for DevOps deployments:

The CN-Series firewall is specifically designed to secure containerized environments and is ideal for protecting extensive DevOps deployments. It integrates seamlessly with Kubernetes and other container orchestration platforms, providing the necessary security controls for DevOps processes.

Creating a New Virtual Switch:

By creating a new virtual switch, you can segment the network within the ESXi environment. The VM-Series firewall can then be used to provide security controls between these virtual switches using virtual wire mode.

Zero Trust implementation revolves around the principle that no entity, inside or outside the network, should be trusted by default. The primary methods that benefit an organization are:

Security automation is seamlessly integrated: Zero Trust requires continuous monitoring and verification of every device and user attempting to access resources. Automation helps in efficiently managing these processes, ensuring that security policies are consistently enforced without human error. Automated tools can quickly detect anomalies, respond to threats, and update access controls dynamically.

To configure a default route to an internet router, you need to perform the following steps:

Select Network > Virtual Router, then select the default link to open the Virtual Router dialog.

Select the Static Routes tab, then click Add to create a new static route.

These steps ensure that the default route is correctly added to the virtual router configuration, allowing traffic to be directed to the appropriate internet gateway.

Palo Alto Networks has deep integrations with:

Cisco ACI:Integration with Cisco Application Centric Infrastructure (ACI) allows for automated security provisioning and enforcement within the Cisco data center environment, leveraging the tight coupling of network and security policies.

VMware NSX-T:Integration with VMware NSX-T enables advanced security features and visibility within VMware's software-defined data center (SDDC) environment, facilitating automated security policies and enforcement across virtualized workloads.

Advanced URL Filtering (AURLF) leverages machine learning (ML) to provide real-time analysis and defense against new and unknown threats:

Real-time analysis: AURLF uses ML models to analyze web traffic in real-time, identifying malicious URLs and preventing access to harmful content before it reaches the user.

Defending against new and unknown threats: The ML capabilities allow the system to detect and block previously unknown threats by analyzing patterns and behaviors associated with malicious URLs, ensuring a proactive security posture.

This step involves setting up a connection between Panorama (the centralized management platform for Palo Alto Networks firewalls) and the VMware NSX Manager. This communication is essential for managing and orchestrating the VM-Series firewalls within the NSX environment.
