What type of technologies do boundary control devices include?

Boundary control devices primarily encompass networking technologies that manage and filter data traffic entering and exiting a network. Firewalls and routers, as examples of this category, are critical in establishing a security perimeter by controlling and monitoring incoming and outgoing network traffic based on predetermined security rules.

Firewalls serve as the first line of defense in a network, effectively blocking unwanted and potentially harmful traffic while allowing authorized communications. Routers also contribute to network security by directing data packets and safeguarding networks from external threats through various security protocols.

This focus on networking technologies is essential in boundary control as they help protect sensitive information and a network's integrity. Unlike other options, which may deal with specific aspects of security or data protection, boundary control devices are fundamentally designed for managing the flow of data across network boundaries. An understanding of these devices is crucial for maintaining effective cybersecurity measures in any organization.
