RF (radio frequency) and microwave systems use electromagnetic signals to transmit, receive, or process information, typically through components such as antennas, amplifiers, filters, and receivers. Microwave engineering focuses on higher-frequency portions of the radio spectrum, where design and testing require specialized techniques.
In cyber security, engineering firms working with these technologies may handle sensitive design files, prototypes, test results, and customer specifications. Attackers who access such data could expose intellectual property or disrupt development and manufacturing. Defenders should protect engineering workstations and repositories with strong access controls, multifactor authentication, network segmentation, and tested backups. The term describes a technical field; by itself, it does not indicate that a company has been compromised.
