Definition
External refers to elements, systems, or entities that exist outside the immediate control or boundary of an organization's internal network or core operations. It encompasses anything that interacts with the organization from the outside, such as third-party vendors, public networks, customer interfaces, or cloud services. In practice, managing external connections involves establishing secure protocols and access controls to ensure data integrity and system availability. Understanding external dependencies is crucial for robust risk management and maintaining operational resilience. For instance, a company's reliance on a cloud-based customer relationship management system represents an external dependency. This differs from internal resources which are managed directly within the organization's infrastructure. Concepts related to external access and security are frequently tested in domains like CompTIA Security+ and AWS Certified Solutions Architect Associate.
