Answer
Correct Answer: The use of Internet protocols with limited access to company data by the company's customers and suppliers.
Explanation
Introduction / Context:Organizations extend selected systems to trusted external parties (customers, vendors, partners) using secure, Internet-based technologies. This controlled extension is known as an extranet.
Given Data / Assumptions:
- Audience includes external stakeholders needing limited, role-based access.
- Security and segregation of duties are essential.
- Technologies include VPN, SSO, and web portals.
Concept / Approach:An extranet exposes specific services or data using Internet protocols while enforcing strict access controls and auditing. It differs from an intranet (internal users) and the public Internet (open access).
Step-by-Step Solution:
Identify whether users are external or internal.Check access scope: limited vs. unlimited.Select the definition that mentions external parties with limited access.Verification / Alternative check:Standards-based network architectures and security policies define extranets as partner-access portals with least-privilege access.
Why Other Options Are Wrong:Unlimited access violates least privilege. Internal users refer to an intranet, not an extranet.
Common Pitfalls:Confusing extranet with VPN-only access; VPN may be one mechanism but the concept is broader and policy-driven.
Final Answer:The use of Internet protocols with limited access to company data by the company's customers and suppliers.
