When investigatinglogs for upload attempts that were recently blocked due to sensitive information leaks, the appropriateSecurity Profileto query isData Filtering.

Why Data Filtering?Data Filtering is acontent inspection security profilewithin Palo Alto NetworksNext-Generation Firewalls (NGFWs)that detects and prevents the unauthorized transmission ofsensitive or confidential data. This security profile is designed to inspectfiles, text, and patternsin network traffic and block uploads that matchpredefined data patternssuch as:

Personally Identifiable Information (PII)– e.g., Social Security Numbers, Credit Card Numbers, Passport Numbers

Financial Data– e.g., Bank Account Numbers, SWIFT Codes

Health Information (HIPAA Compliance)– e.g., Patient Medical Records

Custom Data Patterns– Organizations can define proprietary data patterns for detection

Firewall Policy Application– The Data Filtering profile is attached to Security Policies that inspect file transfers (HTTP, FTP, SMB, SMTP, etc.).

Traffic Inspection– The firewall scans the payload forsensitive data patternsbefore allowing or blocking the transfer.

Alert and Block Actions– If sensitive data is detected in an upload, the firewall canalert,block, orquarantinethe file transfer.

Log Investigation– Security Administrators can analyzeThreat Logs (Monitor > Logs > Data Filtering Logs)to review:

File Name

Destination IP

Source User

Matched Data Pattern

Action Taken (Allowed/Blocked)

Firewall Deployment– Data Filtering is enforced at the firewall level to preventsensitive data exfiltration.

Security Policies– Configured to enforce Data Filtering rules based onbusiness-critical data classifications.

VPN Configurations– Ensures encrypted VPN traffic is also subject to data inspection to prevent insider data leaks.

Threat Prevention– Helps mitigate the risk ofdata theft, insider threats, and accidental exposureof sensitive information.

WildFire Integration– Data Filtering can work alongsideWildFireto inspect files foradvanced threats and malware.

Panorama– Providescentralized visibility and managementof Data Filtering logs across multiple firewalls.

Zero Trust Architectures– Aligns withZero Trustprinciples by enforcing strictcontent inspection and access control policiesto prevent unauthorized data transfers.

Panoramais Palo Alto Networks’centralized management platformforNext-Generation Firewalls (NGFWs). One of its key functions is toaggregate and analyze logs from multiple firewalls, which significantly enhancesreporting and visibilityacross an organization's security infrastructure.

Centralized Log Collection– Panorama collectslogs from multiple firewalls, allowing administrators to analyze security events holistically.

Advanced Data Analytics– It providesrich visual reports, dashboards, and event correlationfor security trends, network traffic, and threat intelligence.

Automated Log Forwarding– Logs can beforwarded to SIEM solutionsor stored forlong-term compliance auditing.

Enhanced Threat Intelligence– Integrated withThreat Prevention and WildFire, Panorama correlates logs to detectmalware, intrusions, and suspicious activityacross multiple locations.

B. By automating all Security policy creations for multiple firewalls.❌

Incorrect, becausewhile Panorama enables centralized policy management, it doesnot fully automate policy creation—administrators must still define and configure policies.

C. By pushing out all firewall policies from a single physical appliance.❌

Incorrect, becausePanorama is available as a virtual appliance as well, not just a physical one.

While itpushes security policies, its primary enhancement to reporting islog aggregation and analysis.

D. By replacing the need for individual firewall deployment.❌

Incorrect, becausefirewalls are still requiredfor traffic enforcement and threat prevention.

Panorama does not replace firewalls; itcentralizes their management and reporting.

Firewall Deployment– Panorama providescentralized log analysisfor distributed NGFWs.

Security Policies– Supportspolicy-based logging and compliance reporting.

VPN Configurations– Provides visibility intoIPsec and GlobalProtect VPN logs.

Threat Prevention– Enhances reporting formalware, intrusion attempts, and exploit detection.

WildFire Integration– StoresWildFire malware detection logsfor forensic analysis.

Zero Trust Architectures– Supports log-basedrisk assessment for Zero Trust implementations.

To monitor traffic for Internet of Things (IoT) devices that may not otherwise be visible, the network design should place the firewalloutside the DHCP pathand use traffic mirroring from the switch to a TAP (Test Access Point) interface on the firewall.

Traffic Mirroring: Switches mirror the traffic to the firewall's TAP interface, enabling the firewall to inspect the traffic without directly interfering with the device communication.

IoT Monitoring: Many IoT devices use lightweight communication protocols or non-standard methods, making direct interception difficult. Traffic mirroring allows passive monitoring for behavioral analysis, anomaly detection, and threat prevention.

Firewall Placement: Keeping the firewall outside the DHCP path ensures that monitoring does not disrupt IoT device communications while still providing visibility into their network activity.

When adding a new sanctioned cloud application toSaaS Data Security, the tool establishes API access by receiving anOAuth tokenor a similar type of token from the cloud application.

API Integration: The token allows the SaaS Data Security solution to authenticate itself with the cloud application, enabling secure monitoring and management of user activity, data flow, and security events.

Token Usage: The token maintains the connection between the SaaS application and the security tool, ensuring seamless communication while enforcing access policies and monitoring for anomalies.

Security: This method ensures that API access is secure and prevents unauthorized access to the cloud application.

OAuth Authentication and API Access

InStrata Cloud Manager (SCM), policies need to balanceprivacywhile ensuringsecure decryption for mobile users in Prisma Access. The correct approach involves:

SSL Forward Proxy (C)– Enablesdecryption of outbound SSL traffic, allowing security inspection while ensuring unauthorized data does not leave the network.

No Decryption (D)–Excludes personal data from being decrypted, ensuring compliance withprivacy regulations(e.g., GDPR, HIPAA) and protecting sensitive employee information.

SSL Forward Proxy (C)

Decrypts outbound SSL trafficfrom mobile users.

Inspects traffic for malware, data exfiltration, and compliance violations.

Ensurescorporate security policiesare enforced on user traffic.

No Decryption (D)

Ensuresprivacy-sensitive traffic(e.g., online banking, healthcare portals) remainsuntouched.

Exclusionscan be defined based oncategories, user groups, or destinations.

Helps maintainregulatory compliancewhile still securing other traffic.

(A) SSH Decryption– Not relevant in this context, as SSH traffic is typically used for administrative access rather than mobile user web browsing.

(B) SSL Inbound Inspection– Used forinbound traffic to company-hosted servers, not for securing outbound traffic from mobile users.

Firewall Deployment– SSL Forward Proxy enables traffic visibility, No Decryption protects privacy.

Security Policies– Defines what traffic should or should not be decrypted.

Threat Prevention & WildFire– Decryption helps detect hidden threats while excluding sensitive personal data.

Zero Trust Architectures– Ensuresleast-privilege access while maintaining privacy compliance.

Why These Two Policies?Other Answer Choices AnalysisReferences and Justification:Thus,SSL Forward Proxy (C) and No Decryption (D) are the correct answers, as they balance security and privacy for mobile users in Prisma Access.

To generate authorization codes for Software Next-Generation Firewalls (NGFWs), it is necessary to create a deployment profile within the Palo Alto Networks Customer Support Portal (CSP). This process involves defining the specifics of your deployment, such as the desired firewall model, associated subscriptions, and other relevant configurations.

Once the deployment profile is established, the CSP generates an authorization code corresponding to the specified configuration. This code is then used during the firewall's activation process to license the software and enable the associated subscriptions.

It's important to note that authorization codes are not typically obtained directly from public cloud marketplaces or through Enterprise Support Agreement (ESA) codes. Additionally, while registering the device with the cloud service provider is a necessary step, it does not, by itself, generate the required authorization codes.
