Port 445 is used by the SMB protocol on Windows systems. Large volumes of unexpected traffic on TCP 445 are commonly associated with worms that exploit SMB vulnerabilities (such as WannaCry or NotPetya). Worms are self-replicating malware that spread rapidly across a network, consuming bandwidth, causing high latency, and often resulting in network outages. This matches the scenario given, where network unavailability and abnormal port 445 traffic are observed.

Aconflict of interest (B)arises when personal relationships or interests could potentially influence professional decisions. In this case, the CFO's friendship with the vendor could improperly affect the procurement decision-making process.

This scenario falls underDomain 5.3: Explain the importance of frameworks, policies, procedures, and controls—specifically under“Personnel policies (e.g., conflict of interest, mandatory vacations, job rotation).”

Validating the code signature is the best way to verify software authenticity, as it ensures that the software has not been tampered with and that it comes from a verified source. Code signatures are digital signatures applied by the software vendor, and validating them confirms the software's integrity and origin.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

A Statement of Work (SOW) is a formal document detailing the scope, deliverables, timeline, and estimated hours for services such as penetration testing engagements.

BPA (Blanket Purchase Agreement) covers recurring purchases, SLA (Service Level Agreement) defines service quality expectations, and NDA (Non-Disclosure Agreement) protects confidentiality, none of which specify hours or detailed scope.

SOWs are fundamental in managing third-party risk and engagements, covered under Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】.

Detailed Explanation:

Daily vulnerability scans help identify missing patches or updates across endpoints, allowing security teams to ensure compliance with patch management policies. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Vulnerability Management"​​.

Passive reconnaissance involves gathering publicly available information about a target without directly interacting with the target systems. Checking OSINT (Open Source Intelligence) sources is a typical passive technique used to collect data without alerting the target.

Active reconnaissance (A) involves direct interaction with the target. Offensive (C) and defensive (D) refer to broader security postures and are not specific reconnaissance types.

Passive reconnaissance is a foundational step in penetration testing and covered in the Threats and Vulnerabilities domain of SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】
