Having WildFire machine learning (ML) capability inline on the firewall provides significant advantages in real-time threat prevention.

Inline ML Capability:

The firewall can analyze and block unknown malicious files in real-time, preventing the first instance of infection (patient zero).

This enhances security without disrupting business productivity, as threats are mitigated immediately.

When having a customer pre-sales call, the aspect of the NGFW that should be covered is:

A. The NGFW simplifies your operations through analytics and automation while giving you consistent protection through exceptional visibility and control across the data center, perimeter, branch, mobile, and cloud networks.

This aspect highlights the key benefits of using the NGFW, such as operational simplification through advanced analytics and automation, and comprehensive protection across various parts of the network. This message effectively communicates the value proposition of the NGFW to potential customers, making it a crucial point to cover in pre-sales discussions.

Logs from various products can be sent to the Cortex Data Lake, which serves as a centralized logging and data repository:

PA-3260 firewall: This next-generation firewall (NGFW) is capable of forwarding comprehensive logs, including threat, traffic, and user activity data, to the Cortex Data Lake for centralized analysis and response.

Prisma Access: This cloud-delivered security service ensures secure access to applications and data from anywhere. It integrates with Cortex Data Lake to provide consistent security across all users, irrespective of their location, by logging security events and user activities​ (Palo Alto Networks)​​ (Palo Alto Networks)​​ (Palo Alto Networks)​.

For large-scale deployments of Next-Generation Firewalls (NGFWs) with multiple Panorama Management Servers, the Panorama Interconnect plugin is essential. This plugin enables the interconnection and management of multiple Panorama instances, allowing for centralized policy management and configuration across a distributed network environment. It ensures scalability and efficient management in large deployments.

The Palo Alto Networks Cloud Identity Engine (CIE) includes services such as Directory Sync and Cloud Authentication Service. These services support identity providers (IdP) using standards like SAML 2.0 and OAuth2. Directory Sync ensures that user and group information from on-premises directories are available in the cloud, while Cloud Authentication Service facilitates secure authentication and single sign-on (SSO) for users.

Palo Alto Networks updates Command-and-Control (C2) signatures frequently to ensure the latest threats are detected and blocked. The recommended schedule for updating C2 signatures is once a day. This daily update ensures that the firewall has the most current threat intelligence, providing robust protection against C2 traffic.

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.

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.

WildFire, a cloud-based threat analysis service from Palo Alto Networks, is capable of detecting zero-day malware across several types of traffic, including SMTP, HTTPS, and FTP. By analyzing files transmitted over these protocols, WildFire can identify malicious activities that traditional security measures might miss. SMTP (Simple Mail Transfer Protocol) is used for email transmission, HTTPS (HyperText Transfer Protocol Secure) secures web traffic, and FTP (File Transfer Protocol) is used for file transfers. These protocols are commonly exploited by attackers to distribute malware, making WildFire’s ability to monitor and analyze them critical for comprehensive network security.

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.
