質問 # 132
A security operations team is transitioning from alert-driven investigations to a mature threat hunting program. The team wants to focus on detecting adversaries who intentionally evade signature-based tools and traditional SIEM alerts by using legitimate credentials and native system utilities. Which hunting focus best supports this objective?
正解：B
解説：
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.
質問 # 133
Which of the following statements best describes the concept of threat hunting?
正解：C
質問 # 134
A SOC team using Cisco security technologies wants to improve its ability to detect threats that bypass traditional security controls by abusing valid user credentials. Which hunting focus MOST effectively addresses this challenge?
正解：B
解説：
The correct answer isanalyzing authentication behavior anomalies across users and devices. Credential abuse is one of the most common and effective techniques used by modern attackers because it allows them to blend in with legitimate activity and bypass malware-based defenses.
Options A and B rely on malware indicators, which are often absent in credential-based attacks. Option D addresses only one potential delivery or command-and-control vector and does not detect misuse of valid credentials.
By analyzing authentication behavior, threat hunters can detect:
* Impossible travel scenarios
* Abnormal login times
* Excessive failed logins followed by success
* Logins from unusual devices or locations
Cisco tools such asCisco Secure Network Analytics, VPN telemetry, and identity logs provide rich data sources for this type of hunting. This approach focuses onIndicators of Attack (IOAs)rather than Indicators of Compromise (IOCs), pushing detection higher on thePyramid of Pain.
Within theCBRTHD blueprint, hunting for credential misuse is a core competency, especially in cloud and remote-access environments. Detecting these behaviors early significantly reduces attacker dwell time and limits the blast radius of compromise.
Therefore,Option Cis the most effective and Cisco-aligned answer.
質問 # 135
Which step in threat modeling involves analyzing the impact of potential threats on system assets?
正解：D
質問 # 136
While investigating multiple incidents, analysts notice that attackers consistently use SMB for lateral movement and avoid PowerShell execution. Why is this observation valuable for attribution?
正解：D
解説：
The correct answer isit highlights consistent attacker tradecraft. Attribution depends on recognizing behavioral patternsthat persist across campaigns.
Attackers frequently change malware, infrastructure, and exploits, but they are far less likely to changehow they prefer to operate. Consistent use of SMB for lateral movement and deliberate avoidance of PowerShell reflect conscious operational choices.
Option A is unrelated to lateral movement behavior. Option B assumes malware development, which may not exist. Option D addresses impact, not attribution.
Cisco-aligned threat hunting usesMITRE ATT&CK technique mappingto correlate observed behaviors with known threat actor profiles. These behavioral fingerprints provide far stronger attribution confidence than low-level indicators.
Therefore,Option Cis the correct answer.
