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​​​.

Comprehensive and Detailed Explanation From Exact Extract:

A playbook is a step-by-step, just-in-time reference used by Security Operations Center (SOC) analysts when responding to security alerts, incidents, and suspicious activities. Playbooks provide documented procedures for common scenarios such as malware detection, phishing investigations, ransomware response, and account compromise.

According to the CompTIA Security+ SY0-701 exam framework, playbooks support incident response by reducing analyst guesswork and ensuring consistency. They include details such as triage steps, required tools, escalation paths, log sources, and containment actions. This makes playbooks the most suitable document for immediate reference during live investigations.

Change management policies (A) govern system or configuration changes, not SOC operations. Risk profiles (B) provide organizational risk overviews, not incident-response steps. SIEM profiles (D) define correlation rules or dashboards but are not procedural guides.

Therefore, the correct answer is playbooks, which enable efficient, standardized, and repeatable responses to operational security events.

A warm site offers a compromise between cost and recovery speed. It includes hardware and network infrastructure partially configured, allowing quicker recovery than a cold site but at lower cost than a hot site.

Hot sites (A) enable rapid recovery but at high cost. Cold sites (B) are low cost but slow to recover. Manual (C) refers to manual processes, typically slower.

Warm sites balance recovery time and cost in disaster recovery planning【6:Chapter 9†CompTIA Security+ Study Guide】.
