Question 1: 

What is the primary function of the CrowdStrike Falcon sensor?

A) To provide antivirus scanning only

B) To collect endpoint telemetry and enforce prevention policies

C) To manage network firewall rules

D) To perform vulnerability scanning

Answer: B

Explanation:

The primary function of the CrowdStrike Falcon sensor is to collect endpoint telemetry data and enforce prevention policies on protected systems. The sensor is a lightweight agent installed on endpoints that continuously monitors system activity, captures security events, and sends this telemetry to the CrowdStrike cloud for analysis. The sensor also enforces prevention policies configured by administrators to block malicious activities in real-time based on indicators of attack and behavioral analytics.

The Falcon sensor operates using a combination of cloud-delivered threat intelligence and on-sensor prevention capabilities. It monitors processes, file system activity, network connections, registry changes, and other system behaviors to detect suspicious activities. When threats are identified, the sensor can take immediate action according to configured policies, including blocking malicious processes, quarantining files, and preventing network connections to malicious destinations.

The sensor’s architecture is designed for minimal performance impact while providing comprehensive visibility. It uses event-driven data collection rather than continuous scanning, which reduces resource consumption compared to traditional antivirus solutions. The sensor communicates with the CrowdStrike cloud infrastructure over encrypted channels, sending collected telemetry for correlation with global threat intelligence and advanced analytics powered by machine learning models.

While the Falcon platform includes prevention capabilities that go beyond traditional antivirus, the sensor itself is not limited to antivirus scanning. It does not manage network firewall rules, which are typically handled by separate network security devices or host-based firewalls. Vulnerability scanning is a separate function provided by different CrowdStrike modules or external tools. The sensor’s core purpose is comprehensive endpoint detection and response through telemetry collection and policy enforcement.

Question 2: 

Which CrowdStrike cloud region should be selected during sensor deployment?

A) The region closest to the administrator’s location

B) The region where the organization’s Falcon instance is hosted

C) Any region, as they are all interconnected

D) The region with the lowest latency

Answer: B

Explanation:

During sensor deployment, you must select the cloud region where your organization’s Falcon instance is hosted. CrowdStrike operates multiple independent cloud instances across different geographic regions including US-1, US-2, EU-1, and GovCloud. Each customer’s Falcon tenant exists in one specific region, and sensors must be configured to communicate with the correct regional cloud instance. Using the wrong region will prevent sensors from connecting to your Falcon console and registering properly.

The cloud region is determined when your CrowdStrike Falcon tenant is initially provisioned and cannot be changed after deployment. The region selection typically considers data residency requirements, compliance regulations, and geographic proximity to your primary operations. For example, European organizations often choose EU-1 to comply with GDPR data residency requirements, while US government entities use the GovCloud region for FedRAMP compliance.

When downloading sensor installers from the Falcon console, the installers are automatically configured with the correct Customer ID (CID) and cloud region information for your tenant. However, administrators must ensure they are using the correct sensor package for their region, especially in organizations with complex deployments or when managing multiple Falcon tenants. The sensor installer includes region-specific connection information that directs the sensor to communicate with the appropriate cloud infrastructure.

While latency and proximity are considerations in overall performance, they are not the primary factors for region selection during deployment. The sensor must connect to the specific region where your tenant exists, regardless of physical distance. Regions are not interconnected for customer data, as each operates as an independent instance to ensure data isolation and compliance. Selecting any region arbitrarily or choosing based solely on administrator location will result in deployment failures.

Question 3: 

What is a Host Group in CrowdStrike Falcon?

A) A physical collection of servers in a data center

B) A logical grouping of hosts for applying policies and managing endpoints

C) A network segment defined by IP addresses

D) A group of users with similar permissions

Answer: B

Explanation:

A Host Group in CrowdStrike Falcon is a logical grouping of hosts used for applying policies and managing endpoints collectively. Host Groups allow administrators to organize endpoints based on business requirements, security posture, or operational characteristics, enabling efficient policy management at scale. Rather than configuring policies for individual hosts, administrators assign policies to Host Groups, and all members of that group inherit the assigned policies automatically.

Host Groups provide flexibility in endpoint management by allowing multiple organizational schemes. Common approaches include grouping by function such as servers, workstations, or point-of-sale systems, by environment like production, staging, or development, by geographic location, by business unit or department, or by sensitivity level requiring different security controls. Hosts can be assigned to Host Groups manually by administrators or automatically through assignment rules based on host properties.

The Host Group assignment is a critical component of the Falcon policy hierarchy. Each host must belong to at least one Host Group, with new hosts typically assigned to a default group until administrators reassign them. When a host belongs to multiple groups through nested structures or multiple assignments, policy precedence rules determine which policies apply. Prevention policies, response policies, sensor update policies, and other configuration elements are all associated with Host Groups.

Host Groups are not physical collections of hardware or network segments defined by IP addressing, which are infrastructure concepts rather than policy management constructs. They are not related to user groups or role-based access control, though user permissions may determine which Host Groups an administrator can manage. Host Groups are specifically logical constructs within the Falcon platform designed for endpoint policy management and operational organization.

Question 4: 

Which protocol does the Falcon sensor use to communicate with the CrowdStrike cloud?

A) FTP

B) HTTPS

C) SSH

D) Telnet

Answer: B

Explanation:

The Falcon sensor uses HTTPS (HTTP over TLS/SSL) to communicate with the CrowdStrike cloud infrastructure. All sensor-to-cloud communications are encrypted using industry-standard TLS encryption, ensuring that telemetry data, policy updates, and commands are transmitted securely. The use of HTTPS provides both encryption for data confidentiality and authentication to verify that sensors are communicating with legitimate CrowdStrike cloud services rather than malicious infrastructure.

The sensor initiates outbound HTTPS connections to CrowdStrike cloud services on port 443, which is the standard port for HTTPS traffic. This design choice offers significant deployment advantages because port 443 is typically allowed through corporate firewalls for normal web browsing, minimizing the need for special firewall rules. The sensor does not require inbound connections, reducing attack surface and simplifying network security configurations.

Communication occurs over multiple HTTPS channels for different purposes including sensor check-in and heartbeat, telemetry data upload, policy and configuration updates, threat intelligence synchronization, and real-time query responses. The sensor maintains persistent connections when possible to minimize latency and enable rapid response to threats. If connectivity is temporarily lost, the sensor queues data locally and automatically reconnects when network access is restored.

FTP is an unencrypted file transfer protocol that does not provide adequate security for endpoint telemetry. SSH is typically used for remote shell access rather than endpoint agent communications. Telnet is a legacy protocol without encryption, making it completely unsuitable for secure endpoint management. Only HTTPS provides the combination of encryption, authentication, and firewall compatibility needed for secure and reliable sensor-to-cloud communication in enterprise environments.

Question 5: 

What is the purpose of the Customer ID (CID) in CrowdStrike Falcon?

A) To identify individual users within an organization

B) To uniquely identify a customer’s Falcon instance

C) To track billing information

D) To define network segments

Answer: B

Explanation:

The Customer ID (CID) uniquely identifies a customer’s Falcon instance within the CrowdStrike cloud infrastructure. Each CrowdStrike customer receives a unique CID when their Falcon tenant is provisioned, and this identifier is embedded in sensor installers to ensure sensors register with the correct customer tenant. The CID acts as a critical security mechanism to prevent sensors from accidentally or maliciously registering to incorrect Falcon instances, ensuring complete tenant isolation and data segregation.

The CID is a hexadecimal string that includes both the unique identifier and a checksum for validation. When a sensor is installed, it uses the embedded CID to authenticate with the CrowdStrike cloud and register the endpoint to the correct customer account. The CID is visible in the Falcon console and can be found in sensor installer properties, host management pages, and API documentation. Administrators need the CID when downloading sensor installers, configuring deployment tools, and integrating with APIs.

CID security is critical because it controls which tenant receives endpoint data. Organizations should treat the CID as sensitive information and implement appropriate controls to prevent unauthorized access. If a CID is compromised, malicious actors could potentially register rogue sensors to an organization’s Falcon instance. CrowdStrike provides CID rotation capabilities for situations where CID exposure is suspected, allowing organizations to generate new CIDs while maintaining continuity of protection.

The CID does not identify individual users, as user management uses separate authentication systems. While billing is associated with customer accounts, the CID’s primary purpose is technical identification rather than financial tracking. Network segmentation is handled through separate networking and policy configurations, not through the CID. The CID’s singular purpose is uniquely identifying and isolating customer Falcon instances in the multi-tenant cloud environment.

Question 6: 

Which prevention policy setting controls whether the sensor blocks malicious activity automatically?

A) Detection Mode

B) Prevention Mode

C) Monitor Mode

D) Audit Mode

Answer: B

Explanation:

Prevention Mode is the prevention policy setting that controls whether the Falcon sensor automatically blocks malicious activity when detected. When Prevention Mode is enabled, the sensor actively prevents malicious behaviors, processes, and files from executing based on the configured prevention policies and threat intelligence. This mode provides real-time protection by stopping attacks as they occur, preventing malware execution, blocking exploit techniques, and interrupting malicious network connections before damage can occur.

Prevention policies in Falcon include multiple categories of protections including malware prevention, exploit mitigation, behavior-based prevention, machine learning detection, and indicator of attack blocking. Each category can be configured independently with different action settings. Within each category, administrators can choose between prevention modes where detections trigger automatic blocking, or detection-only modes where events are logged but not blocked, allowing organizations to tune policies before enforcing them.

The transition from detection to prevention is a critical consideration in deployment strategies. Many organizations start with detection-only settings to establish baselines, tune policies, and identify false positives before enabling full prevention. This phased approach allows security teams to understand the impact of prevention policies on business operations and adjust configurations to balance security and operational requirements. Falcon’s detailed detection data helps inform these tuning decisions.

Detection Mode typically refers to operation where activity is identified and logged without prevention. Monitor or Audit Mode similarly implies observation without blocking. While these terms are used in various security products, within CrowdStrike Falcon, Prevention Mode specifically indicates the active blocking posture. The distinction between detection and prevention is fundamental to endpoint security strategy, allowing organizations to progressively increase protection levels as confidence and tuning mature.

Question 7: 

What does IOA stand for in the context of CrowdStrike Falcon?

A) Indicator of Attack

B) Index of Applications

C) Internet Outbound Access

D) Internal Operations Analysis

Answer: A

Explanation:

IOA stands for Indicator of Attack in the context of CrowdStrike Falcon. IOAs represent behavioral patterns and techniques that indicate an attack is in progress, focusing on adversary tactics, techniques, and procedures rather than specific file signatures. This approach aligns with the MITRE ATT&CK framework and enables detection of novel attacks that have never been seen before, including zero-day exploits and fileless malware, by identifying malicious behavior rather than relying solely on known malware signatures.

IOAs differ fundamentally from traditional Indicators of Compromise (IOCs). While IOCs identify artifacts left after a compromise such as malicious file hashes, IP addresses, or domains, IOAs detect the attack techniques being used in real-time. For example, an IOC might identify a specific malware file hash, but an IOA detects the behavior of credential dumping or lateral movement regardless of which tool is used. This behavioral approach provides more robust and enduring protection against evolving threats.

CrowdStrike’s threat intelligence team continuously develops and refines IOAs based on real-world attack observations, adversary research, and emerging threat patterns. IOAs are delivered to sensors through cloud updates, ensuring endpoints have current protection against the latest attack techniques without requiring sensor upgrades. The Falcon platform includes thousands of IOAs covering the full attack lifecycle from initial access through execution, persistence, privilege escalation, defense evasion, credential access, discovery, lateral movement, collection, and exfiltration.

Index of Applications, Internet Outbound Access, and Internal Operations Analysis are not standard security terms in the CrowdStrike context. The concept of Indicators of Attack is central to Falcon’s prevention and detection philosophy, representing a paradigm shift from signature-based detection to behavior-based threat identification. Understanding IOAs is essential for effectively configuring and managing the Falcon platform.

Question 8: 

Which feature allows administrators to search for threats across all endpoints in the environment?

A) Host Management

B) Real Time Response

C) Falcon Discover

D) Investigate / Event Search

Answer: D

Explanation:

The Investigate or Event Search feature allows administrators to search for threats across all endpoints in the environment by querying the centralized repository of endpoint telemetry data. This powerful search capability enables security analysts to hunt for indicators of compromise, investigate suspicious activities, identify patterns across multiple hosts, and conduct proactive threat hunting. Event Search provides access to vast amounts of endpoint data collected by Falcon sensors, making it possible to answer complex security questions at enterprise scale.

Event Search uses a query language that allows filtering and searching across multiple data dimensions including process executions, network connections, file operations, registry modifications, authentication events, and detection alerts. Administrators can search by various criteria such as file names, hashes, IP addresses, domains, user names, command lines, and timestamps. Queries can span all endpoints or be limited to specific hosts, Host Groups, or time ranges, providing flexibility for different investigation scenarios.

The search capability is powered by CrowdStrike’s cloud infrastructure, which indexes and stores endpoint telemetry data for rapid retrieval. Search results are presented in a timeline view showing the sequence of events, which helps analysts understand attack progression and causality. Analysts can pivot from search results to related events, examine full process trees, and access detailed event metadata. This investigative capability is essential for incident response, threat hunting, and forensic analysis.

Host Management provides tools for viewing and managing individual endpoints but does not offer comprehensive threat searching across all hosts. Real Time Response enables interactive access to individual endpoints for investigation and remediation but is not a platform-wide search tool. Falcon Discover focuses on asset inventory and application visibility rather than threat searching. Only the Investigate or Event Search feature provides the cross-endpoint threat hunting and investigation capabilities described.

Question 9: 

What is the minimum operating system requirement for installing the Falcon sensor on Windows?

A) Windows XP

B) Windows 7 SP1

C) Windows 10 only

D) Windows Server 2019 only

Answer: B

Explanation:

The minimum operating system requirement for installing the Falcon sensor on Windows is Windows 7 SP1 for workstations and Windows Server 2008 R2 SP1 for servers. CrowdStrike maintains support for these older operating systems to accommodate enterprise environments that may still have legacy systems in operation, though the company encourages migration to supported operating systems. The sensor is compatible with both 32-bit and 64-bit Windows architectures on supported platforms.

Supported Windows versions include Windows 7 SP1 and later workstation operating systems including Windows 8.1, Windows 10, and Windows 11, as well as Windows Server 2008 R2 SP1 and later server operating systems including Windows Server 2012, 2016, 2019, and 2022. The sensor receives regular updates to support new Windows versions as they are released. CrowdStrike provides a detailed compatibility matrix documenting supported versions, with recommendations to use currently supported Microsoft operating systems for best security posture.

System requirements beyond the operating system version include processor architecture with x86 or x64 CPU, minimum RAM typically 2GB though more is recommended for optimal performance, disk space for sensor installation typically under 500MB, and network connectivity for cloud communication. The sensor is designed to have minimal performance impact, typically consuming less than 1 percent CPU and under 100MB RAM during normal operations.

Windows XP is not supported as it is long past Microsoft’s end-of-life date and lacks security features present in modern Windows versions. While Windows 7 SP1 is the minimum, Windows 10 is not the minimum requirement, as older supported versions can run the sensor. Similarly, Windows Server 2019 is not required, as the sensor supports much older server versions. Understanding operating system compatibility is important for deployment planning and ensuring complete endpoint coverage.

Question 10: 

Which Falcon module provides vulnerability assessment capabilities?

A) Falcon Prevent

B) Falcon Insight

C) Falcon Spotlight

D) Falcon OverWatch

Answer: C

Explanation:

Falcon Spotlight provides vulnerability assessment capabilities within the CrowdStrike Falcon platform. Spotlight continuously evaluates endpoints for software vulnerabilities without requiring traditional scanning agents or scheduled scan windows. It leverages the existing Falcon sensor to identify installed applications, match them against vulnerability databases, and prioritize vulnerabilities based on actual exploit risk rather than just theoretical severity scores. This approach provides always-current vulnerability visibility without performance impact from scanning.

Spotlight vulnerability assessment is powered by the telemetry already collected by Falcon sensors, which track installed applications, versions, and configurations. This data is correlated with vulnerability intelligence databases including CVE information, vendor security advisories, and exploit availability data. Spotlight provides risk-based prioritization using CrowdStrike’s ExPRT.AI engine, which evaluates whether vulnerabilities are actually being exploited in the wild, helping security teams focus on the most critical risks first.

The vulnerability data is presented in the Falcon console with detailed reporting showing vulnerable applications, affected hosts, vulnerability severity and exploitability, and remediation recommendations. Spotlight integrates with patch management workflows by identifying which systems need updates and tracking remediation progress. The continuous assessment model means vulnerability data is always current, updating automatically as new vulnerabilities are disclosed or as endpoint software changes through updates or new installations.

Falcon Prevent is the malware and threat prevention module that blocks attacks in real-time. Falcon Insight provides endpoint detection and response capabilities for investigating threats. Falcon OverWatch is the managed threat hunting service where CrowdStrike experts proactively hunt for threats. While these modules are critical for threat prevention and detection, only Falcon Spotlight specifically addresses vulnerability assessment and management within the Falcon platform.

Question 11: 

What is Real Time Response (RTR) used for in CrowdStrike Falcon?

A) Automated threat prevention

B) Interactive remote access to endpoints for investigation and remediation

C) Network traffic monitoring

D) Email security scanning

Answer: B

Explanation:

Real Time Response (RTR) provides interactive remote access to endpoints for investigation and remediation activities. RTR enables security analysts to establish command-line sessions to individual hosts through the Falcon cloud infrastructure, allowing them to collect additional forensic data, analyze suspicious activities, remediate threats, and restore normal operations without needing separate remote access tools. This capability is essential for incident response when automated actions are insufficient and human judgment is required.

RTR operates through the existing Falcon sensor and cloud infrastructure, eliminating the need for direct network connectivity to endpoints. Analysts initiate RTR sessions from the Falcon console, and commands are relayed through the CrowdStrike cloud to the sensor on the target host. This architecture works across network boundaries, enabling analysts to reach endpoints on remote networks, behind NAT, or on mobile devices regardless of their location. All RTR activity is logged and auditable for security and compliance purposes.

RTR provides multiple command sets with different privilege levels. Read-only commands allow analysts to gather information without modifying the system, including file browsing, process listing, and registry inspection. Active responder commands enable more invasive actions such as file quarantine, process termination, and evidence collection. Administrative commands provide full system control for remediation actions. Role-based access control determines which analysts can execute which command levels on which hosts.

Common RTR use cases include collecting memory dumps or file samples for analysis, terminating malicious processes, identifying persistence mechanisms, extracting forensic artifacts like logs or registry keys, and remediating infections through file deletion or registry modification. While automated threat prevention handles most threats, RTR provides the flexibility for complex incidents requiring human expertise. RTR is not used for network monitoring or email security, which are separate security domains.

Question 12: 

How often does the Falcon sensor check in with the CrowdStrike cloud by default?

A) Every 5 minutes

B) Every 15 minutes

C) Every hour

D) Continuously maintains a persistent connection

Answer: D

Explanation:

The Falcon sensor continuously maintains persistent connections with the CrowdStrike cloud rather than checking in at fixed intervals. This always-on connectivity model enables real-time threat prevention, immediate policy updates, and rapid response capabilities. The persistent connection architecture allows the cloud to push updates, queries, and commands to sensors instantly rather than waiting for scheduled check-ins, significantly reducing response time to emerging threats and enabling interactive features like Real Time Response.

The persistent connection model provides several operational advantages including immediate detection and alerting with minimal delay between threat identification and security team notification, real-time policy enforcement where configuration changes take effect within seconds across all connected endpoints, instant threat intelligence updates ensuring sensors have current protection against emerging threats, and bidirectional communication enabling cloud-initiated queries and commands for investigation and response.

The sensor manages these connections efficiently to minimize bandwidth consumption and performance impact. While the connection is persistent, not all data is transmitted continuously. The sensor intelligently batches telemetry data, compresses transmissions, and prioritizes critical events for immediate upload while queuing lower-priority data. If connectivity is temporarily lost due to network issues, the sensor queues data locally and automatically reconnects when possible, ensuring no security data is lost.

Fixed interval check-ins like every 5, 15, or 60 minutes represent legacy endpoint security architectures where agents poll management servers periodically. This polling model creates detection and response gaps during intervals between check-ins. The CrowdStrike architecture specifically moved away from this model to provide continuous protection and enable rapid response. Understanding this architectural difference is important for comparing Falcon with legacy security solutions.

Question 13: 

Which user role has full administrative access to all Falcon features?

A) Analyst

B) Responder

C) Falcon Administrator

D) User Administrator

Answer: C

Explanation:

The Falcon Administrator role has full administrative access to all features and capabilities within the CrowdStrike Falcon platform. This role can perform all configuration changes, manage all policies, access all detection data, control user accounts and roles, modify Host Groups and assignments, and configure integrations with external systems. The Falcon Administrator role should be assigned carefully and limited to personnel who require complete platform control, following the principle of least privilege.

CrowdStrike Falcon implements role-based access control (RBAC) with multiple predefined roles designed for different job functions and responsibility levels. Each role grants specific permissions aligned with common security team responsibilities. The role hierarchy typically includes read-only analyst roles for viewing detections and investigating incidents, responder roles for taking action on threats and conducting investigations, administrator roles for configuration management, and specialized roles for specific functions like managing Real Time Response or Falcon Discover.

The Falcon Administrator can delegate responsibilities by assigning appropriate roles to other users. For example, security analysts might receive permissions to investigate detections and search events but not modify prevention policies. Incident responders might have authority to quarantine files and execute RTR commands but not change Host Group assignments. This granular permission model allows organizations to implement proper separation of duties while ensuring each team member has the access needed for their responsibilities.

The Analyst role typically provides read-only access for investigation without action capabilities. The Responder role adds incident response permissions but not administrative configuration control. User Administrator is not a standard Falcon role name, though some organizations create custom roles for delegated user management. Only the Falcon Administrator role provides complete platform control across all features, making it the highest privilege level in the system.

Question 14:

What is the primary purpose of the Sensor Update Policy?

A) To update the operating system

B) To control when and how Falcon sensors receive updates

C) To update application software

D) To configure Windows Update settings

Answer: B

Explanation:

The primary purpose of the Sensor Update Policy is to control when and how Falcon sensors receive updates from CrowdStrike. This policy allows administrators to manage the sensor update process according to organizational requirements, balancing the need for current protection with change management processes and stability requirements. Organizations can choose between different update strategies including automatic updates where sensors receive the latest version immediately, scheduled updates that occur during maintenance windows, or staged rollouts that test updates on pilot groups before broader deployment.

Sensor updates include improvements to detection capabilities, performance optimizations, bug fixes, and new features. CrowdStrike regularly releases sensor updates through multiple update channels or stages including Early Adopter for testing new functionality, Production for general deployment with proven stability, Long Term Support for conservative update strategies, and Legacy versions for compatibility with specific environments. Organizations select which update stage their Host Groups follow based on their risk tolerance and operational requirements.

The Sensor Update Policy can be applied to different Host Groups, enabling organizations to implement phased deployment strategies. A common approach is to assign test or development hosts to Early Adopter builds for initial validation, production systems to Production builds for stability, and critical systems to LTS builds for maximum stability. This staged approach allows organizations to identify potential issues before they impact critical operations while maintaining current protection on the majority of endpoints.

Sensor Update Policies do not manage operating system updates, which are handled by native OS update mechanisms or third-party patch management tools. They do not update general application software, which requires separate software deployment processes. They also do not configure Windows Update settings, which are managed through Group Policy or configuration management tools. The Sensor Update Policy specifically and exclusively controls Falcon sensor version management and deployment.

Question 15: 

Which detection severity level indicates the most critical threats in Falcon?

A) Low

B) Medium

C) High

D) Critical

Answer: D

Explanation:

Critical is the detection severity level that indicates the most severe threats in CrowdStrike Falcon. Critical severity detections represent confirmed malicious activity with high confidence, significant impact potential, and immediate risk to the organization. These detections typically involve known malware execution, active command and control communication, data exfiltration attempts, or successful privilege escalation. Critical detections should trigger immediate investigation and response to prevent or minimize damage from active attacks.

Falcon uses a four-tier severity classification system: Critical for confirmed high-impact threats requiring immediate attention, High for serious threats with strong malicious indicators, Medium for suspicious activities that may indicate compromise but require additional investigation, and Low for potentially unwanted programs or behaviors that may be undesirable but are not clearly malicious. The severity rating helps security teams prioritize investigations and allocate resources effectively based on threat urgency.

Severity ratings are assigned through a combination of automated analysis and expert curation. Machine learning models evaluate behaviors against known attack patterns, threat intelligence correlates detections with observed adversary techniques, and confidence scoring assesses the likelihood of true malicious intent versus benign activity. CrowdStrike threat researchers continuously refine severity assignments based on emerging threats and attack evolution, ensuring the rating system remains accurate and useful for prioritization.

Security operations teams typically establish response workflows based on severity levels, with Critical detections triggering immediate 24/7 response, High severity requiring same-day investigation, Medium severity reviewed during business hours, and Low severity handled through routine processes. This tiered approach ensures critical threats receive immediate attention while preventing alert fatigue from lower-priority detections. Understanding severity levels is essential for effective security operations and incident response planning.
