PCCP Questions and Answers

Detection of threats using data analysis – SIEM platforms analyze collected data to identify suspicious patterns and detect threats.

Ingestion of log data – SIEM systems collect and centralize log data from various sources, which is essential for analysis, correlation, and alerting.

Automation and prevention are more aligned with SOAR and firewall/EDR functionalities, not the core operations of SIEM.

SOAR (Security Orchestration, Automation, and Response) differs from SIEM by adding automated incident response and workflow orchestration to the detection and alerting capabilities found in SIEM. This enables faster and more efficient handling of security incidents.

Endpoint Detection and Response (EDR) technologies provide comprehensive visibility and real-time threat prevention directly on endpoint devices. EDR continuously monitors process activities, file executions, and system calls to detect malware, suspicious behaviors, and zero-day threats at the source. Palo Alto Networks’ Cortex XDR platform exemplifies this by correlating endpoint telemetry with network and cloud data to provide a holistic defense against attacks. Operating locally on endpoints allows EDR to prevent lateral movement and respond to threats quickly, filling security gaps that network-centric tools alone cannot address. This endpoint-level insight is critical to identifying sophisticated threats that initiate or manifest on user devices.

Managed Detection and Response (MDR) services combine incident impact analysis and proactive threat hunting to enhance organizational security posture. Incident impact analysis assesses the severity, scope, and potential damage of identified threats, helping prioritize responses. Proactive threat hunting involves skilled analysts searching for hidden threats that automated detection may miss, leveraging threat intelligence and behavioral analytics. Palo Alto Networks’ MDR integrates Cortex XDR and human expertise to detect, investigate, and remediate sophisticated threats early. Unlike routine firewall updates or development processes, MDR is focused on active threat discovery and comprehensive incident management.

The Privilege Escalation tactic in the MITRE ATT&CK framework involves techniques used by attackers to gain higher-level permissions on a system or network, allowing greater access to internal servers and sensitive data.

An Advanced Persistent Threat (APT) is a long-term, targeted cyberattack where data exfiltration is often the primary objective. Attackers maintain a covert presence in the network to steal sensitive information over time.

A container-based NGFW is specifically designed to integrate with Kubernetes environments, providing full application visibility and control within containerized workloads. It operates at the pod level, making it ideal for securing dynamic microservices architectures.

Authorization is the component of the AAA (Authentication, Authorization, and Accounting) framework that regulates user access and permissions to resources after identity has been verified. It determines what actions or resources a user is allowed to access.

SOAR platforms are unique in their ability to automate incident response through the use of predefined workflows. These workflows allow repetitive security tasks to be executed automatically, improving response speed and efficiency.

An effective Attack Surface Management (ASM) process requires a real-time, data-rich inventory of all internet-facing assets. This enables continuous visibility, timely detection of vulnerabilities, and identification of exposures that attackers could exploit.

A physical firewall is ideal for environments like a company headquarters that require redundant power, high throughput, and dedicated hardware for maximum reliability and performance. It supports more robust failover and scalability compared to virtual or containerized options.

Heap spray attacks exploit memory management vulnerabilities by injecting malicious code into a program’s heap to manipulate execution flow. Endpoint Detection and Response (EDR) platforms monitor memory and process behavior on endpoints, enabling the detection of such memory-based exploits through anomaly and behavior analysis. Palo Alto Networks’ Cortex XDR equips SOC teams with the tools to detect, analyze, and respond to heap spray and other in-memory attacks on company laptops in real time. EDR’s endpoint-centric visibility is crucial since heap spray attacks operate below network layers and often bypass traditional perimeter defenses.

Attack Surface Management (ASM) platforms focus on continuous discovery and monitoring of all internet-facing assets, both internal and external, to identify attack vectors, vulnerabilities, and exposures that could be exploited by threat actors.

A Cloud Access Security Broker (CASB) secures SaaS applications and network data by providing visibility, data security, threat protection, and compliance enforcement. It acts as a control point between users and cloud service providers to enforce security policies.

DNS tunneling is an attack technique where data packets are disguised as DNS queries and sent to a remote server. That server, often under the attacker's control, responds with additional data or instructions, effectively creating a covert command-and-control (C2) channel over DNS.

A containerized architecture packages software along with its dependencies, libraries, and configuration into an isolated unit called a container. This ensures consistent behavior across environments and simplifies deployment and scaling.
