Detailed Explanation:This scenario highlights the need for training on the secure use of removable media.
Users should learn to avoid using untrusted external storage devices to prevent malware infections. Reference:
CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Removable Media Controls and User Awareness Training".

To reduce risky behaviors such as clicking suspicious emails, the first and most effective step is to implement a phishing awareness campaign that educates users about recognizing phishing attempts, the risks involved, and safe practices. Awareness training can significantly reduce successful phishing attacks by changing user behavior.
Updating policies (A) is important but does not directly affect user behavior immediately. Password management solutions (B) help with credential security but do not reduce phishing click rates. Issuing warning letters (C) is punitive and less effective than proactive education.
This approach aligns with Security Program Management principles emphasizing training and awareness as primary controls against phishing risks#6:Chapter 16 CompTIA Security+ Study Guide#.

An Intrusion Prevention System (IPS) uses packet inspection (either signature-based, anomaly-based, or both) to analyze network traffic and detect malicious patterns. Configuring packet inspection is the first step to ensure the IPS can identify and respond to specific attack signatures.
Reference:
CompTIA Security+ SY0-701 Official Study Guide, Domain 3.2: "IPS devices must be configured to inspect network packets for attack patterns." Exam Objectives 3.2: "Summarize security implications of embedded and specialized systems."

A Virtual Private Network (VPN) is the best solution to allow remote employees secure access to company resources without interception concerns. A VPN establishes an encrypted tunnel over the internet, ensuring that data transferred between remote employees and the company is secure from eavesdropping.
Proxy server helps with web content filtering and anonymization but does not provide encrypted access.
NGFW (Next-Generation Firewall) enhances security but is not the primary tool for enabling remote access.
Security zone is a network segmentation technique but does not provide remote access capabilities.
