Question 34: 

Which authentication method does Prisma Access support for user identity?

A) Only local user database

B) SAML, RADIUS, certificates, and Active Directory integration

C) Only username and password

D) Only multi-factor authentication

Answer: B

Explanation:

Prisma Access supports comprehensive authentication methods including SAML for single sign-on integration, RADIUS for network access control, certificate-based authentication for strong cryptographic identity verification, and Active Directory integration for enterprise directory services. This multi-method support enables organizations to leverage existing identity infrastructure while implementing security controls appropriate for different access scenarios and risk profiles.

SAML integration enables single sign-on experiences where users authenticate through existing identity providers like Okta, Azure AD, Ping Identity, or other SAML 2.0 compliant systems. Users log in once to their identity provider and receive seamless access to resources protected by Prisma Access without repeated authentication prompts. SAML assertions carry user identity and group membership information that Prisma Access uses for policy enforcement. This integration centralizes identity management and supports modern authentication workflows including conditional access and adaptive authentication.

RADIUS authentication supports network access control scenarios where users authenticate against RADIUS servers that may front-end Active Directory, LDAP directories, or other authentication databases. RADIUS integration is common in environments with existing network access infrastructure or requiring integration with multi-factor authentication systems that present RADIUS interfaces. The protocol supports challenge-response mechanisms enabling complex authentication workflows including one-time passwords and hardware token validation.

Certificate-based authentication provides strong cryptographic identity verification without password transmission. Users or devices present digital certificates issued by trusted certificate authorities during connection establishment. Prisma Access validates certificates against configured trust chains and extracts identity information from certificate fields for policy enforcement. Certificate authentication is particularly valuable for automated systems, service accounts, or high-security environments requiring non-repudiation and strong identity assurance.

Active Directory integration retrieves user and group information for policy enforcement. Prisma Access queries Active Directory servers to retrieve group memberships and user attributes enabling policies based on organizational units, security groups, or user properties. This integration ensures policies align with existing organizational structure and access control models. The integration supports multiple Active Directory domains and forests accommodating complex enterprise directory architectures.

Local databases (option A) exist but aren’t the only method, passwords alone (option C) are insufficient, and MFA (option D) is one component. Prisma Access provides comprehensive multi-method authentication support.

Question 35: 

What is the purpose of Prisma Access Explicit Proxy deployment mode?

A) To provide DNS resolution

B) To enable proxy-aware applications to send traffic directly to Prisma Access without agents

C) To manage firewalls

D) To monitor network bandwidth

Answer: B

Explanation:

Explicit Proxy deployment mode enables proxy-aware applications and systems to send traffic directly to Prisma Access security services without requiring GlobalProtect agents or network-level redirections. This deployment approach is particularly valuable for environments with applications that natively support proxy configurations, unmanaged devices where agent installation is prohibited, or scenarios requiring simplified deployment without endpoint software.

The explicit proxy architecture operates through standard proxy protocols where applications are configured with proxy server addresses pointing to Prisma Access infrastructure. When applications make web requests, they send them to the configured proxy address rather than directly to destination servers. Prisma Access receives these proxy requests, applies security policies including threat prevention, URL filtering, and data loss prevention, and forwards permitted requests to destinations. Responses flow back through Prisma Access to originating applications.

Explicit proxy supports both HTTP and HTTPS traffic with SSL forward proxy inspection capabilities enabling decryption and inspection of encrypted traffic. Applications present CONNECT requests for HTTPS destinations which Prisma Access intercepts, establishing separate encrypted sessions to both the application and destination server. This man-in-the-middle inspection requires distributing Prisma Access certificate authority certificates to client systems for trust chain validation.

Common use cases include securing unmanaged BYOD devices where corporate agents cannot be installed but users can configure proxy settings, supporting Linux servers or containers where GlobalProtect agents are unavailable or undesirable, enabling legacy applications with built-in proxy support, and implementing security for guest users or contractors requiring temporary access without full agent deployment. Explicit proxy provides flexibility for heterogeneous environments with diverse device types and management approaches.

The deployment mode supports authentication through various methods including transparent authentication using SAML or certificates, and basic authentication using usernames and passwords. User identity information enables applying identity-aware security policies even without agents. PAC files can automate proxy configuration distribution simplifying client setup. Integration with endpoint discovery tools identifies devices using explicit proxy for inventory and compliance tracking.

DNS resolution (option A) is separate service, firewall management (option C) is administrative function, and bandwidth monitoring (option D) is a feature component. Explicit Proxy specifically enables agentless proxy-based security delivery.

Question 36: 

Which layer does Prisma Access operate at to provide security services?

A) Layer 2 only

B) Layer 3 only

C) Layers 3-7 providing network and application-layer security

D) Layer 7 only

Answer: C

Explanation:

Prisma Access operates at layers 3 through 7 of the OSI model, providing comprehensive security services spanning network-layer packet filtering through application-layer content inspection and threat prevention. This multi-layer approach enables protection against diverse threats ranging from network-based attacks to sophisticated application-layer exploits, delivering defense-in-depth security architecture through cloud-delivered services.

Layer 3 and 4 capabilities include traditional firewall functionality with stateful packet inspection examining IP addresses, protocols, and ports to enforce network segmentation and access control policies. NAT services translate private addresses to public addresses enabling internet access while hiding internal network topology. Routing capabilities direct traffic between networks and through security inspection points. These foundational network security functions establish baseline protection preventing unauthorized network access.

Layer 7 application identification uses App-ID technology to identify applications regardless of port, protocol, or encryption. This deep packet inspection examines application signatures, protocol decoders, and behavioral characteristics to accurately classify traffic as specific applications like Office 365, Salesforce, or custom business applications. Application visibility enables creating security policies based on what applications users access rather than just network ports, providing granular control aligned with business needs.

Content inspection at layer 7 includes URL filtering examining requested URLs against categorized databases to block access to malicious or inappropriate sites, file type identification controlling which file types can transfer through the network, and data pattern matching detecting sensitive information in transit. Threat prevention inspects application payloads for exploits, malware, and command-and-control traffic using signatures, behavioral analysis, and machine learning. SSL decryption enables inspecting encrypted traffic that would otherwise bypass content inspection.

Advanced threat protection extends beyond signature-based detection through WildFire cloud-based analysis that executes suspicious files in sandbox environments to detect zero-day threats, machine learning models identifying malicious behavior patterns, DNS security preventing connections to malicious domains, and IoT security discovering and profiling connected devices. This comprehensive multi-layer protection addresses the full threat landscape from network reconnaissance through advanced persistent threats.

Layer 2 only (option A) and layer 3 only (option B) are insufficient for modern threats, layer 7 only (option D) misses network-layer attacks. Layers 3-7 provide comprehensive multi-layer security.

Question 37: 

What is the purpose of Prisma Access GlobalProtect client?

A) To manage cloud infrastructure

B) To provide secure connectivity and enforce security policies on endpoint devices

C) To backup data

D) To monitor server performance

Answer: B

Explanation:

GlobalProtect client provides secure connectivity between endpoint devices and Prisma Access infrastructure while enforcing security policies, device posture checks, and user authentication directly on endpoints. This software agent is fundamental to Prisma Access Mobile Users deployment, creating encrypted tunnels that protect traffic from endpoint devices to cloud security services regardless of user location or network.

The client operates across multiple platforms including Windows, macOS, Linux, iOS, and Android, ensuring consistent security coverage across the diverse device ecosystem modern enterprises support. After installation, the client establishes IPsec or SSL VPN tunnels to Prisma Access gateways, automatically selecting optimal gateway locations based on user geographic position. This transparent connectivity ensures low-latency access to corporate resources and internet applications while routing traffic through security inspection.

Security policy enforcement occurs before tunnel establishment through Host Information Profile checks that assess device security posture. The client verifies antivirus software is installed and current, disk encryption is enabled, operating system patches meet requirements, and other security controls are present before allowing network access. Devices failing these checks can be denied access or granted limited connectivity to remediation resources. This posture-based access control prevents compromised or non-compliant devices from accessing corporate resources.

Split tunneling configuration provides flexibility in how traffic is routed. Organizations can configure all traffic to route through Prisma Access tunnels for maximum visibility and security, or implement policy-based split tunneling where specific applications or destinations route through tunnels while others access directly. This capability balances security requirements with performance optimization and bandwidth conservation. Application-based split tunneling uses App-ID to make per-application routing decisions without requiring destination IP knowledge.

The GlobalProtect client provides additional capabilities including always-on VPN ensuring connectivity establishes automatically without user intervention, pre-logon connectivity enabling authentication to domain controllers before user login, portal and gateway separation where users connect to portals for authentication and configuration retrieval before tunneling to gateways, and clientless VPN for browser-based access when client installation is not possible.

Infrastructure management (option A) requires different tools, backup (option C) is separate function, and server monitoring (option D) is unrelated. GlobalProtect specifically provides endpoint connectivity and security enforcement.

Question 38: 

Which feature in Prisma Access provides visibility into unmanaged SaaS applications?

A) Firewall policies

B) SaaS Security Inline and API-based discovery

C) URL filtering

D) Threat prevention

Answer: B

Explanation:

SaaS Security provides comprehensive visibility into unmanaged SaaS applications through both inline traffic inspection and API-based discovery, enabling organizations to identify shadow IT, assess security risks, and implement appropriate controls for cloud application usage. This dual-approach visibility addresses the challenge of unsanctioned cloud application proliferation where employees adopt cloud services without IT approval or oversight.

Inline SaaS discovery operates through Prisma Access traffic inspection where advanced application identification techniques analyze user web traffic to detect access to thousands of SaaS applications. The system identifies not just major platforms like Office 365 or Salesforce, but also niche and emerging cloud services that users might adopt independently. Classification extends beyond simple URL categorization to understand specific cloud services within multi-tenant platforms, distinguishing between storage, collaboration, and productivity services.

API-based discovery complements inline inspection by connecting directly to sanctioned SaaS platforms through their APIs to discover additional unauthorized applications. For example, connecting to Office 365 APIs reveals third-party applications that users have authorized to access corporate data through OAuth grants. Similarly, Google Workspace API connections identify apps accessing Gmail or Drive. This API visibility exposes application integrations that wouldn’t appear in network traffic inspection.

Risk assessment capabilities evaluate discovered SaaS applications across multiple dimensions including security posture examining encryption, authentication methods, and compliance certifications, vendor reputation assessing the application provider’s security history and business stability, data handling practices understanding where data is stored and how it’s protected, and compliance alignment checking whether applications meet industry regulatory requirements. Automated risk scoring helps prioritize remediation efforts.

The visibility enables informed decision-making about SaaS adoption through reports showing application usage patterns, users accessing risky applications, data volumes uploaded to cloud services, and trends in cloud application proliferation. Administrators can create policies allowing approved applications, blocking high-risk applications, warning users about medium-risk applications, or requiring additional authentication for sensitive cloud services. Integration with CASB capabilities extends visibility into application activity and data sharing.

Firewall policies (option A) control traffic, URL filtering (option C) blocks sites, and threat prevention (option D) stops exploits. SaaS Security specifically provides cloud application visibility and risk assessment.

Question 39: 

What is the purpose of Prisma Access bandwidth management?

A) To increase internet speed

B) To control and allocate bandwidth for different traffic types based on policies

C) To reduce hardware costs

D) To encrypt all traffic

Answer: B

Explanation:

Bandwidth management in Prisma Access enables controlling and allocating network bandwidth for different traffic types based on business policies, ensuring critical applications receive necessary bandwidth while preventing less important traffic from consuming excessive capacity. This QoS capability is essential for maintaining application performance and user experience in environments where multiple traffic types compete for limited bandwidth resources.

The bandwidth management architecture operates through QoS policies that classify traffic into priority classes based on application identification, user identity, or traffic characteristics. Administrators define bandwidth guarantees ensuring minimum bandwidth allocation for critical applications like voice and video conferencing, bandwidth limits capping maximum bandwidth for less critical applications like software updates or personal streaming, and priority levels determining which traffic receives preference during congestion. These policies apply at tunnel level controlling bandwidth usage by remote networks or mobile user connections.

Traffic classification leverages Prisma Access App-ID capabilities to identify applications accurately regardless of port or protocol. Policies can prioritize business-critical applications like Salesforce or SAP over recreational applications like gaming or personal streaming. User-based policies enable allocating more bandwidth to executives or specific departments while limiting general users. DSCP marking preserves QoS through upstream networks enabling end-to-end traffic prioritization.

Implementation supports various bandwidth management scenarios including prioritizing real-time communications ensuring voice and video calls receive low latency and adequate bandwidth, guaranteeing minimum bandwidth for cloud applications preventing performance degradation, limiting bandwidth for software updates preventing disruption to interactive applications, and managing personal internet usage preventing excessive consumption of corporate bandwidth. Bandwidth pools enable sharing capacity across multiple tunnels while enforcing aggregate limits.

Monitoring and reporting provide visibility into bandwidth utilization showing which applications consume bandwidth, which users or locations exceed allocations, and how effective policies are at maintaining application performance. Analytics identify opportunities for policy optimization such as adding capacity for consistently congested links or adjusting application priorities based on business impact. Integration with application performance monitoring correlates bandwidth availability with user experience metrics.

Increasing internet speed (option A) requires infrastructure changes, reducing costs (option C) is a benefit not purpose, and encryption (option D) is separate security function. Bandwidth management specifically controls bandwidth allocation through policies.

Question 40:

 Which protocol does Prisma Access use for connecting GlobalProtect clients?

A) HTTP only

B) IPsec and SSL VPN protocols

C) FTP

D) Telnet

Answer: B

Explanation:

Prisma Access uses both IPsec and SSL VPN protocols for connecting GlobalProtect clients to cloud infrastructure, providing flexibility to accommodate different network environments, security requirements, and device capabilities. This dual-protocol support ensures reliable connectivity across diverse scenarios including restrictive networks that block certain protocols, devices with varying VPN capabilities, and organizations with different security preferences.

IPsec protocol provides robust, standardized VPN connectivity with strong cryptographic protection and efficient performance. GlobalProtect implements IPsec using industry-standard algorithms including AES encryption for confidentiality, SHA for integrity verification, and protocols like IKEv2 for key exchange and tunnel establishment. IPsec operates at network layer enabling efficient packet processing with minimal overhead, making it ideal for high-throughput scenarios or devices with hardware acceleration capabilities. The protocol supports both tunnel and transport modes with tunnel mode being standard for remote access scenarios.

SSL VPN protocol encapsulates VPN traffic within TLS sessions, enabling connectivity through networks that restrict IPsec traffic such as guest wireless networks, public hotspots, or corporate networks with strict firewall policies. SSL VPN operates at higher layers using TCP port 443 which is typically permitted through firewalls since it’s the standard HTTPS port. This protocol is particularly valuable for accessing corporate resources from restricted networks where IPsec connections would be blocked.

Protocol selection occurs automatically through GlobalProtect client configuration where administrators define preferred protocols and fallback options. The client attempts IPsec connection first for optimal performance, automatically falling back to SSL VPN if IPsec is unavailable or blocked. Manual protocol selection enables users or administrators to choose specific protocols based on network conditions or requirements. Both protocols support similar security features including multi-factor authentication, certificate validation, and policy enforcement.

Performance characteristics differ between protocols with IPsec generally providing better throughput and lower latency due to network-layer operation and hardware acceleration support, while SSL VPN offers superior firewall traversal but potentially higher overhead due to TLS encapsulation and TCP-based transport. Organizations often deploy both protocols enabling automatic selection based on network conditions, ensuring optimal user experience across varying connectivity scenarios.

HTTP (option A) is application protocol, FTP (option C) is file transfer protocol, and Telnet (option D) is terminal emulation. IPsec and SSL VPN specifically provide secure remote access connectivity.

Question 41: 

What is the purpose of App-ID in Prisma Access?

A) To assign IP addresses

B) To identify applications regardless of port, protocol, or encryption for policy enforcement

C) To manage user accounts

D) To configure network routes

Answer: B

Explanation:

App-ID is Palo Alto Networks’ patented application identification technology that accurately identifies applications regardless of port, protocol, evasive techniques, or encryption enabling security policies based on application identity rather than just network ports. This foundational capability transforms security from port-based allow/deny rules to application-aware policies aligned with business requirements, dramatically improving security effectiveness while enabling appropriate application access.

The identification process uses multiple techniques applied in sequence to classify traffic with high accuracy. The process begins with signature matching examining known application patterns in packet payloads, protocols follow examining protocol characteristics and transactions to identify applications, behavioral analysis observing application communication patterns and heuristics, and SSL decryption enabling inspection of encrypted traffic. This multi-faceted approach enables identifying applications that evade simple port-based detection.

App-ID recognizes thousands of applications across categories including business applications like Office 365, Salesforce, and collaboration tools, personal applications like social media and streaming services, infrastructure services like DNS and NTP, and potentially risky applications like peer-to-peer file sharing and anonymizers. The application database receives continuous updates as new applications emerge and existing applications evolve, ensuring identification accuracy remains current.

Policy creation based on App-ID enables granular control aligned with business requirements. Organizations can allow business-critical applications while blocking personal applications, permit collaboration tools but prevent file transfer capabilities within them, allow application access but block risky features like file uploads, and apply different security profiles to applications based on risk assessment. This application-centric approach provides security that adapts to application usage rather than forcing applications into port-based restrictions.

Integration with other security services enhances protection where threat prevention applies application-specific threat signatures, URL filtering blocks command-and-control domains applications might contact, data loss prevention inspects application payloads for sensitive data, and WildFire analyzes files applications transfer. App-ID also enables application usage visibility showing which applications consume bandwidth, which users access specific applications, and trends in application adoption.

IP assignment (option A) is DHCP function, account management (option C) is identity function, and routing (option D) is network function. App-ID specifically provides application identification for security policy enforcement.

Question 42: 

Which deployment model does Prisma Access use to deliver security services?

A) On-premises hardware appliances only

B) Cloud-delivered security as a service from global points of presence

C) Virtual machines in customer data centers

D) Physical security devices at each branch

Answer: B

Explanation:

Prisma Access delivers security services through a cloud-delivered security-as-a-service model from global points of presence distributed across major geographic regions worldwide. This cloud-native architecture eliminates the need for organizations to procure, deploy, and maintain security infrastructure at each location, instead providing elastic, on-demand security services that scale automatically to meet changing requirements.

The global infrastructure consists of security processing nodes deployed in major metropolitan areas across continents including North America, South America, Europe, Middle East, Africa, and Asia Pacific regions. These nodes provide local security services to nearby users and sites, minimizing latency by processing traffic close to its source. The distributed architecture ensures high availability where regional failures don’t impact global service, and optimal performance through geographic proximity reducing round-trip times.

Cloud delivery provides numerous operational advantages including elastic scaling where capacity increases automatically to handle growing user counts or traffic volumes without hardware procurement delays, automatic updates ensuring all security services receive latest threat intelligence and capabilities without maintenance windows, high availability through redundant infrastructure eliminating single points of failure, and simplified operations eliminating hardware lifecycle management including installation, configuration, patching, and replacement.

The service model operates on subscription basis where organizations pay for security services based on usage metrics like user counts, site counts, or bandwidth consumption rather than capital expenditure on hardware. This operational expenditure model aligns costs with actual usage, provides predictable monthly costs, eliminates hardware refresh cycles, and enables rapid scaling up or down based on business changes. Financial flexibility makes security accessible to organizations of all sizes.

Architecture flexibility accommodates hybrid deployments where some locations connect through Prisma Access cloud services while others maintain on-premises security appliances during migration periods or for specific requirements. Integration with on-premises Panorama enables unified management across cloud and on-premises deployments. The cloud-first approach represents modern security architecture aligned with digital transformation and cloud adoption trends.

On-premises appliances (option A) represent traditional model, customer data center VMs (option C) require infrastructure management, and physical branch devices (option D) involve hardware deployment. Cloud-delivered service specifically characterizes Prisma Access SASE architecture.

Question 43: 

What is the purpose of Prisma Access Security Processing Nodes?

A) To store user data permanently

B) To provide distributed security inspection and policy enforcement close to users

C) To manage financial transactions

D) To host email servers

Answer: B

Explanation:

Security Processing Nodes are the distributed compute infrastructure within Prisma Access that perform security inspection and policy enforcement for user traffic, deployed strategically in global locations to provide low-latency security services close to users regardless of geographic distribution. These nodes form the core of Prisma Access cloud security architecture, processing billions of security events daily while maintaining high performance and availability.

Each security processing node contains comprehensive security capabilities including next-generation firewall inspection with stateful packet filtering and application control, threat prevention with intrusion prevention and anti-malware, URL filtering blocking access to malicious or inappropriate sites, DNS security preventing connections to malicious domains, WildFire integration for zero-day threat protection, and SSL decryption enabling inspection of encrypted traffic. This full-stack security ensures consistent protection regardless of which node processes traffic.

Geographic distribution optimizes performance by routing users to nearest nodes reducing latency that would occur if all traffic processed at distant locations. The Prisma Access infrastructure includes dozens of nodes worldwide enabling most users to connect to nodes within their geographic region or country. Intelligent routing selects optimal nodes based on user location, node capacity, and network conditions, automatically adapting to changes. This distribution also provides resilience where regional issues don’t impact global service.

Nodes operate in shared multi-tenant infrastructure where security processing for multiple customers occurs on common hardware with strict isolation between customers. Dedicated compute resources can be allocated for customers requiring performance guarantees or regulatory isolation. The shared model enables efficient resource utilization and cost optimization while maintaining security separation. Automatic scaling provisions additional capacity within nodes or deploys additional nodes as customer traffic grows.

Security policy synchronization ensures all nodes enforce identical policies regardless of which node users connect to. Policy updates propagate globally within seconds enabling centralized policy management while maintaining distributed enforcement. Logs and events from all nodes aggregate to centralized management providing unified visibility across global infrastructure. This combination of distributed enforcement with centralized management delivers both performance and operational simplicity.

Data storage (option A) is separate service, financial transactions (option C) are unrelated, and email hosting (option D) is different function. Security Processing Nodes specifically provide distributed security inspection infrastructure.

Question 44: 

Which feature allows Prisma Access to decrypt and inspect SSL/TLS encrypted traffic?

A) SSL Forward Proxy

B) Port forwarding

C) NAT translation

D) DNS caching

Answer: A

Explanation:

SSL Forward Proxy is the feature that enables Prisma Access to decrypt and inspect SSL/TLS encrypted traffic, allowing security services to examine encrypted application traffic for threats, data exfiltration attempts, and policy violations that would otherwise be invisible within encrypted sessions. This capability is critical as the majority of internet traffic is now encrypted, rendering traditional security that only inspects unencrypted traffic largely ineffective against modern threats.

The SSL forward proxy operates by intercepting SSL/TLS connections from clients and establishing two separate encrypted sessions: one between the client and Prisma Access, and another between Prisma Access and the destination server. This man-in-the-middle approach allows Prisma Access to decrypt traffic, inspect plaintext content for threats and policy violations, and re-encrypt traffic before forwarding. The technique is transparent to applications while enabling comprehensive security inspection.

Implementation requires distributing Prisma Access certificate authority certificates to client devices so encrypted sessions between clients and Prisma Access are trusted. Certificate pinning validation ensures Prisma Access can validate destination server certificates before establishing proxy sessions. The process maintains end-to-end security while enabling inspection by Prisma Access as trusted intermediary. Modern certificate validation including extended validation and certificate transparency checking ensures proxy doesn’t weaken overall security.

Decryption policies provide granular control over which traffic is decrypted based on categories, URLs, users, or applications. Organizations can exclude sensitive traffic like healthcare portals or financial sites from decryption respecting privacy and compliance requirements, decrypt enterprise applications and general internet traffic to detect threats, and implement different policies for different user groups based on risk profiles. Logging records decryption decisions enabling compliance auditing and troubleshooting.

Inspection of decrypted traffic applies the full security stack including threat prevention signatures detecting exploits in encrypted sessions, anti-malware scanning files transferred over HTTPS, data loss prevention examining encrypted uploads for sensitive information, URL filtering blocking malicious sites even when accessed over HTTPS, and WildFire analysis of suspicious files regardless of encryption. Without decryption, these security services would be blind to encrypted threat activity.

Port forwarding (option B) redirects traffic, NAT (option C) translates addresses, and DNS caching (option D) stores DNS records. SSL Forward Proxy specifically enables encrypted traffic inspection.

Question 45: 

What is the purpose of Prisma Access DNS Security service?

A) To provide faster DNS resolution

B) To prevent connections to malicious domains using DNS-based threat intelligence

C) To configure DNS servers

D) To cache DNS queries

Answer: B

Explanation:

DNS Security service prevents connections to malicious domains by analyzing DNS queries in real-time and blocking resolution of domains associated with malware, phishing, command-and-control infrastructure, and other threats. This preventive security approach stops threats at the earliest possible stage by preventing devices from establishing network connections to malicious infrastructure before any data exchange occurs.

The service operates inline in the DNS resolution path where Prisma Access intercepts DNS queries from users and evaluates them against comprehensive threat intelligence before allowing or blocking resolution. The threat intelligence combines multiple sources including domain generation algorithm detection identifying algorithmically created domains used by malware, newly registered domain analysis flagging recently created domains often used in attacks, passive DNS analysis tracking domain resolution patterns and infrastructure changes, and machine learning models identifying suspicious domain characteristics like unusual character patterns or hosting providers.

DNS Security provides protection against multiple threat categories including malware distribution sites preventing users from accessing domains hosting malicious files, phishing sites blocking domains impersonating legitimate organizations to steal credentials, command-and-control domains preventing malware from communicating with attacker infrastructure, cryptomining domains blocking unauthorized cryptocurrency mining scripts, and grayware domains preventing connections to potentially unwanted programs or adware.

Real-time threat intelligence updates ensure protection remains current as new threats emerge and attackers register new domains. The DNS Security cloud continuously analyzes billions of DNS queries globally identifying new threats through collective intelligence and behavioral analysis. Updates propagate to all Prisma Access nodes automatically without requiring manual intervention or maintenance windows. This continuous improvement provides protection against zero-day DNS-based threats.

Visibility and analytics provide insights into DNS security events including which users attempted to access malicious domains indicating potential infections, which threat categories are most prevalent showing attack trends, geographic sources of threats revealing targeted attack campaigns, and blocked domain lists enabling threat hunting and incident response. DNS tunneling detection identifies attempts to exfiltrate data or establish covert channels through DNS, a technique increasingly used by advanced attackers.

Faster resolution (option A) is performance benefit, server configuration (option C) is administration task, and caching (option D) is optimization technique. DNS Security specifically prevents malicious domain connections through threat intelligence.
