Description: The ‘Boundary Defense’ refers to a set of security measures designed to protect the boundary between trusted and untrusted networks. This concept is fundamental in the field of cybersecurity, where organizations seek to establish effective barriers to prevent unauthorized access and protect their digital assets. In an environment where threats are becoming increasingly sophisticated, boundary defense becomes an essential strategy for safeguarding information integrity. The main characteristics of this defense include network segmentation, the use of firewalls, intrusion detection and prevention systems, and the implementation of access policies that regulate who can interact with which resources. The relevance of boundary defense lies in its ability to create a security perimeter that, while not infallible, acts as the first line of defense against external attacks. As organizations adopt more flexible and distributed work models, boundary defense adapts to new realities, integrating cloud technologies and security approaches such as Zero Trust, which challenge the traditional notion of trust in networks.
