Optimization of Computer Network Security Strategies in Port Operations

This research focuses on optimizing the security protection strategy of computer systems in port operations. The purpose is to deal with the increasing network security risks. The team has thoroughly understood the global port computer security environment and pointed out the key points in the current security strategy. Defects, especially in the face of high-end hacker attacks (commonly known as APT) and shortcomings in controlling potential risks within the enterprise. This document in-depth develops a set of mathematical model systems, covering attack graph models, risk assessment models, and models for dynamically adjusting security policies, thereby enabling accurate assessment and efficient response to various security threats, with the help of improved calculation methods And specific case analysis confirms that these architectures are feasible for adjusting and executing security measures in actual application scenarios. The new research results have brought the port's computer defense system to a higher level, and also given the port managers a great gift - a complete set of security policy adjustment tools. In addition, this method is suitable for other key infrastructures. Safety Management is also a valuable reference.
