300-220 Exam Dumps : Conducting Threat Hunting and Defending using Cisco Technologies for Cybersecurity

The correct answer isanalyzing abnormal behavior patterns across identity, endpoint, and network telemetry. This approach represents the foundation of modern threat hunting and directly addresses adversaries who deliberately avoid traditional detections.

Advanced attackers increasingly rely onliving-off-the-land techniques, stolen credentials, and legitimate administrative tools such as PowerShell, WMI, RDP, and cloud APIs. These activities rarely generate malware signatures or known IOCs, making alert-driven and signature-based defenses insufficient. As a result, mature threat hunting programs shift focus towardbehavioral analysis and anomaly detection.

Option A and D rely on static indicators such as IPs, domains, and hashes. These sit at thelowest levels of the Pyramid of Painand are trivial for attackers to change. Option B is purely reactive and limited to known malware, offering little value against stealthy intrusions.

By correlating identity logs (authentication patterns, geolocation anomalies), endpoint telemetry (process execution, parent-child relationships), and network activity (unusual connections, lateral movement patterns), hunters can detectIndicators of Attack (IOAs)rather than waiting for confirmed compromise. This enables identification of credential misuse, privilege abuse, and lateral movement even when no malware is present.

This methodology aligns withMITRE ATT&CK TTP-based hunting, which focuses on tactics and techniques instead of tools or infrastructure. It also reflects a higher tier in theThreat Hunting Maturity Model, where organizations proactively search for unknown threats rather than responding to alerts.

In professional SOC environments, this shift dramatically increases detection coverage against advanced adversaries and reduces dwell time. Therefore, optionCis the most accurate and strategically sound answer.

The correct answer isendpoint memory access telemetry. Credential dumping often involves accessing sensitive memory regions, such as LSASS, rather than deploying obvious malware.

Modern attackers frequently use:

Legitimate tools

In-memory techniques

Living-off-the-land binaries

These methods bypass file-based detection entirely. Email, DNS, and firewall logs provide limited visibility into memory-level abuse.

Endpoint memory telemetry enables detection of:

Unauthorized LSASS access

Suspicious handle requests

Abnormal process injection

This telemetry is foundational for detectingcredential access techniquesin modern environments. Therefore, optionBis correct.

The correct answer isreduction in attacker dwell time. Dwell time measures how long an attacker remains undetected in the environment.

As threat hunting maturity increases:

Detection becomes faster

Behavioral coverage improves

Attackers are identified earlier in the kill chain

Metrics such as alert volume or blocked IPs (Options A and D) do not reflect effectiveness and may even indicate excessive noise. Option B measures inputs, not outcomes.

Cisco’sCBRTHD blueprintfocuses onoutcomes, not activity. Reduced dwell time demonstrates:

Effective hunting

Better visibility

Stronger detection engineering

This metric directly correlates with reduced breach impact and improved resilience.

Therefore,Option Cis the correct and Cisco-aligned answer.
