Which of the following statements regarding border security optimization are true?

The statement regarding border security optimization being aimed at preventing or reducing external network attacks and harm is indeed true. This aligns with the fundamental purpose of implementing security measures at the network border, which is to protect the internal network from unauthorized access and various forms of external attacks such as malware, Distributed Denial of Service (DDoS), and intrusion attempts. By focusing on these preventive measures, organizations can create a more resilient network perimeter that safeguards sensitive information and ensures the continuity of services.

In addition to the correct statement, other choices present relevant aspects of border security optimization, but they expand upon different facets rather than focusing solely on the primary objective of preventing external threats. The position of optimization at the network edge is essential for effective defense, as this location allows for monitoring and controlling data traffic before it enters the protected internal network. Measures that include attack defense technologies, packet filtering, and hardware firewalls are also integral parts of a holistic security strategy, contributing to the overall effectiveness of border security. Lastly, secure user access control is crucial for ensuring that only authorized users can access network resources, which further complements the aim of border security.

Thus, the selected statement accurately reflects the core objective of border security optimization in a network security context.
