CrowdStrike IDP Exam With Confidence Using Practice Dumps

Authentication Traffic Inspection (ATI) is a foundational capability of Falcon Identity Protection that enables the platform to analyze authentication traffic from domain controllers. According to the CCIS documentation, ATI is enabled throughIdentity configuration policies.

Identity configuration policies define how the Falcon sensor captures and inspects authentication-related traffic, including Kerberos, NTLM, LDAP, and other identity protocols. Enabling ATI at this level ensures that domain controllers provide the necessary telemetry for identity risk analysis, detections, and behavioral profiling.

The other options are incorrect because:

Identity management settings focus on identity governance and administration.

Identity detection configuration controls detection logic, not traffic inspection.

Identity protection settings manage high-level configuration but do not directly enable ATI.

Because ATI must be explicitly enabled viaIdentity configuration policies,Option Ais the correct and verified answer.

Falcon Identity Protection identifiesstale endpointsas systems that have not authenticated or shown activity for an extended period and then suddenly become active. According to the CCIS curriculum, an endpoint that has been inactive for90 daysand then resumes activity will trigger aUse of Stale Endpointdetection.

This detection is important because attackers frequently exploit dormant or forgotten systems to re-enter environments, evade monitoring, or move laterally. A long period of inactivity followed by sudden authentication activity is considered a strong identity risk signal.

The 90-day threshold is used to establish a reliable inactivity baseline while minimizing false positives. Shorter timeframes could incorrectly flag normal usage patterns, while longer timeframes could delay detection of genuine threats.

Because Falcon explicitly defines stale endpoint activity using a90-day inactivity window,Option Bis the correct answer.

The CCIS curriculum highlights a critical identity-security concept: when attackers usecompromised credentials, they often bypass traditional malware-based attack phases, including theExecutionphase of the MITRE ATT&CK framework. Because no malicious code needs to be executed, attackers can immediately begin interacting with the environment as a legitimate user.

As a result, threat actors move directly into theDiscoveryphase. During Discovery, attackers enumerate users, groups, privileges, systems, domain relationships, and trust paths to understand the environment and plan further actions. This behavior is commonly observed in identity-based attacks and living-off-the-land techniques.

Falcon Identity Protection is specifically designed to detect this behavior by monitoring authentication traffic, privilege usage, and anomalous identity activity—areas where traditional EDR tools may have limited visibility.

The other options are incorrect:

Initial Access has already occurred via credential compromise.

Weaponization and Execution are not required.

Lateral Movement typically follows Discovery.

Because compromised credentials allow attackers to jump straight intoDiscovery,Option Cis the correct and verified answer.
