Correct answer: Exploitation & privilege escalation phase of the cyber kill chain
Explanation:
After reconnaissance and delivery/phishing, the exploitation phase involves gaining initial access. Privilege escalation and lateral movement allow the attacker to deepen access and maintain persistence. Understanding these phases helps analysts anticipate attacker behavior and intervene effectively — a key concept in incident response frameworks covered by CySA+.

Correct answer: Document root cause, update policies/controls, share findings with stakeholders, improve detection controls
Explanation:
Lessons Learned is about strengthening the security posture: analyzing what went wrong, documenting findings, updating policies or controls (patching, segmentation, detection rules), sharing insights to prevent recurrence, and improving monitoring. This step closes the incident response loop, makes future response smoother, and helps meet compliance/reporting requirements per the Reporting & Communication domain.

Correct answer: To support root-cause analysis, legal/ compliance evidence, and avoid destroying critical clues
Detailed Explanation:
Logs, memory dumps, network captures, and disk images provide forensic evidence of attacker behavior, initial access, lateral movement, and data exfiltration. If remediation proceeds without preservation, crucial data could be overwritten or lost, hindering investigation, compliance reporting, or litigation support. This practice is a fundamental part of incident response lifecycle as defined in CySA+ objectives.

Correct answer: Mean Time To Detect (MTTD) and Mean Time To Respond (MTTR)
Explanation:
MTTD indicates how quickly a team identifies threats; MTTR shows how fast they contain and remediate. These metrics are critical KPIs for SOC performance. The CySA+ Reporting & Communication and Incident Response objectives include metrics and KPIs as part of incident management evaluation.

Correct answer: Security awareness training + email filtering + endpoint protection + timely patching
Explanation:
Defense in depth is key: user training reduces risk of phishing clicks; email filtering helps block malicious payloads; endpoint protection detects and quarantines malware; patching fixes vulnerabilities exploited by malware. Combined, these controls strengthen resilience against social-engineering + malware incidents — consistent with best practices in both Vulnerability Management and Incident Response domains.

Correct answer: MITRE ATT&CK
Detailed Explanation:
The MITRE ATT&CK framework provides a comprehensive matrix of known attacker techniques, procedures, and behaviors. By mapping detected activity (e.g. anomalous processes, lateral movement, privilege escalation) to ATT&CK entries, analysts can more accurately understand the adversary’s tactics, predict potential next steps, and apply appropriate mitigations. The CS0-003 exam explicitly references MITRE ATT&CK as part of incident methodology frameworks.

Correct answer: Incident declaration and communication phase
Explanation:
Proper incident response includes not just technical remediation, but also stakeholder communication, regulatory reporting (if needed), and documentation. Declaring an incident formally triggers process workflows, ensures compliance, and aligns response with organizational policies — covered under Reporting & Communication domain.

Correct answer: Perform root cause analysis and implement lessons learned (e.g. patching, improved controls)
Explanation:
A post-incident review identifies how the breach occurred — whether due to unpatched software, misconfiguration, weak access controls, or human error — and allows applying corrective actions, updating policies, and strengthening defenses. CS0-003 includes post-incident activity and lessons-learned as part of incident management lifecycle.

Correct answer: Contain the incident by isolating affected systems
Explanation:
Containment limits the attacker’s movement and damage spread, preserving evidence while minimizing impact. This can involve network segmentation, disabling compromised accounts, or disconnecting from internet. It is a foundational step in incident response process under CS0-003.

Correct answer: Cyber Kill Chain
Explanation:
The Cyber Kill Chain outlines stages attackers follow—from reconnaissance to actions on objectives. Understanding this helps analysts map detection, containment, and response actions to each attack phase. CySA+ lists attack methodology frameworks (including Kill Chain, MITRE ATT&CK) under its objectives.
