SASE (Secure Access Service Edge) is a cloud-based solution that combines networking and security capabilities to address modern enterprise needs. However, there are scenarios where an on-premises solution is more appropriate.

A . High growth phase with existing and planned mergers, and with acquisitions being integrated.

This scenario typically favors a SASE solution since it provides flexible, scalable, and centralized security that is ideal for integrating newly acquired businesses.

B . Most employees and applications in close physical proximity in a geographic region.

This scenario supports the choice of an on-premises solution. When employees and applications are concentrated in a single geographic region, traditional on-premises firewalls and centralized security appliances provide cost-effective and efficient protection without the need for distributed, cloud-based infrastructure.

C . Hybrid work and cloud adoption at various locations that have different requirements per site.

This scenario aligns with a SASE solution. Hybrid work and varying site requirements are better addressed by SASE's ability to provide consistent security policies regardless of location.

D . The need to enable business to securely expand its geographical footprint.

Expanding into new geographic areas benefits from the scalability and flexibility of a SASE solution, which can deliver consistent security globally without requiring physical appliances at each location.

Key Takeaways:

On-premises solutions are ideal for geographically concentrated networks with minimal cloud adoption.

SASE is better suited for hybrid work, cloud adoption, and distributed networks.

Zero Trust principles revolve around minimizing trust in the network and verifying every interaction. To adopt Zero Trust, customers should start by gaining visibility and understanding the network and its transactions.

A . Understand which users, devices, infrastructure, applications, data, and services are part of the network or have access to it.

The first step in adopting Zero Trust is understanding the full scope of the network. Identifying users, devices, applications, and data is critical for building a comprehensive security strategy.

C . Map the transactions between users, applications, and data, then verify and inspect those transactions.

After identifying all assets, the next step is to map interactions and enforce verification and inspection of these transactions to ensure security.

Why Other Options Are Incorrect

B: Enabling CDSS subscriptions is important for protection but comes after foundational Zero Trust principles are established.

D: Implementing VM-Series NGFWs is part of enforcing Zero Trust, but it is not the first step. Visibility and understanding come first.

Palo Alto Networks' PAN-OS supports API keys for authentication when interacting with the firewall's RESTful and XML-based APIs. By default, API keys do not have an expiration time set, but the expiration time for API keys can be configured by an administrator to meet specific requirements, such as a time-based deactivation after two hours. This is particularly useful for compliance and security purposes, where API keys should not remain active indefinitely.

Here's an evaluation of the options:

Option A: This is incorrect because the default setting for API keys does not include an expiration time. By default, API keys are valid indefinitely unless explicitly configured otherwise.

Option B: This is incorrect because PAN-OS fully supports API keys. The API keys are integral to managing access to the firewall's APIs and provide a secure method for authentication.

Option C: This is incorrect because PAN-OS does support API key expiration when explicitly configured. While the default is 'no expiration,' the feature to configure an expiration time (e.g., 2 hours) is available.

Option D (Correct): The correct response to the RFP clause is that the default API key settings need to be modified to set the expiration time to 120 minutes (2 hours). This aligns with the customer requirement to enforce API key deactivation based on time. Administrators can configure this using the PAN-OS management interface or the CLI.

How to Configure API Key Expiration (Steps):

Access the Web Interface or CLI on the firewall.

Navigate to Device > Management > API Key Lifetime Settings (on the GUI).

Set the desired expiration time (e.g., 120 minutes).

Alternatively, use the CLI to configure the API key expiration:

set deviceconfig system api-key-expiry <time-in-minutes>

commit

Verify the configuration using the show command or by testing API calls to ensure the key expires after the set duration.

When sizing a Palo Alto Networks NGFW appliance, it's crucial to consider variables that affect its performance and capacity. These include the network's traffic characteristics, application requirements, and expected workloads. Below is the analysis of each option:

Option A: Connections per second

Connections per second (CPS) is a critical metric for determining how many new sessions the firewall can handle per second. High CPS requirements are common in environments with high traffic turnover, such as web servers or applications with frequent session terminations and creations.

This is an important sizing variable.

Option B: Max sessions

Max sessions represent the total number of concurrent sessions the firewall can support. For environments with a large number of users or devices, this metric is critical to prevent session exhaustion.

This is an important sizing variable.

Option C: Packet replication

Packet replication is used in certain configurations, such as TAP mode or port mirroring for traffic inspection. While it impacts performance, it is not a primary variable for firewall sizing as it is a specific use case.

This is not a key variable for sizing.

Option D: App-ID firewall throughput

App-ID throughput measures the firewall's ability to inspect traffic and apply policies based on application signatures. It directly impacts the performance of traffic inspection under real-world conditions.

This is an important sizing variable.

Option E: Telemetry enabled

While telemetry provides data for monitoring and analysis, enabling it does not significantly impact the sizing of the firewall. It is not a core variable for determining firewall performance or capacity.

This is not a key variable for sizing.

A . Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.

PAN-OS includes the Policy Optimizer tool, which helps migrate legacy port-based rules to application-based policies incrementally and safely. This tool identifies unused, redundant, or overly permissive rules and suggests optimized policies based on actual traffic patterns.

Why Other Options Are Incorrect

B: The migration wizard does not automatically convert port-based rules to application-based rules. Migration must be carefully planned and executed using tools like the Policy Optimizer.

C: Running two firewalls in parallel adds unnecessary complexity and is not a best practice for migration.

D: While port-based rules are supported, relying on them defeats the purpose of transitioning to application-based security.
