An Op Amp, short for operational amplifier, is a high-gain electronic device used to amplify weak electrical signals. While primarily an electronic component, Op Amps can be found in various security hardware, such as intrusion detection systems, where they amplify sensor signals for processing. In cybersecurity, understanding Op Amps is important for hardware security professionals, as vulnerabilities in analog circuits can be exploited for attacks like signal injection or eavesdropping. Proper shielding and secure circuit design help mitigate such risks, ensuring the integrity of security devices that rely on analog signal processing.
