Methodology for selecting information security tools for an airline based on the branch-and-bound method

Modern requirements for the rational use of aircraft enterprise networks and their information security determine the choice of relevant information security tools. Currently, the market offers a wide range of certified information security tools, making it difficult to choose the optimal option. To address this issue, the article proposes a methodology based on the branch-and-bound method for selecting information security tools for processing personal data in aircraft enterprise information systems. This methodology allows for finding the optimal solution within the framework of a deterministic linear model of discrete optimization, eliminating inefficient options in the initial stages.
