The CLI command that allows you to view latency, jitter, and packet loss on a virtual SD-WAN interface is:

show sdwan path-monitor stats vif

This command displays the statistics related to the virtual SD-WAN interface, including important metrics such as latency, jitter, and packet loss. These metrics are crucial for monitoring the performance and quality of the SD-WAN connections to ensure optimal network performance and quick identification of issues.

In PAN-OS, when a portable executable (PE) file larger than 10 MB (default threshold) is encountered, it is not forwarded to the WildFire cloud service. This is due to size limitations on file submissions to the service.

Default Behavior:

Files exceeding the size limit are not forwarded to WildFire for analysis.

The Vulnerability Protection profile on Palo Alto Networks Next-Generation Firewall includes signatures to protect against a variety of threats, including brute force attacks.

Vulnerability Protection Profile:

This profile contains specific signatures designed to detect and block attempts to exploit vulnerabilities, including those used in brute force attacks.

Palo Alto Networks uses proprietary technologies to identify and control traffic sources regardless of IP address or network segment. These technologies include:

User-ID (A): This technology maps IP addresses to user identities, allowing policies to be enforced based on user or group identity rather than just IP addresses. This is especially useful in dynamic environments where IP addresses can change frequently.

Device-ID (A): This technology helps to identify and control devices accessing the network. It provides visibility into which devices are on the network and ensures that policies can be applied based on device type and identity.

Using a virtual wire (vWire) interface configuration can enhance the security of a production online system while minimizing the impact on the existing network.

Virtual Wire:

A vWire interface operates transparently at Layer 2, allowing the firewall to inspect traffic without making changes to the existing network topology.

This mode is ideal for inline deployments where minimal changes to the network configuration are desired.
