broad tuning range is vital in cybersecurity, where threats can come from various sources operating at
different frequencies.

The Role of SDRs in Cybersecurity

High-performance SDRs play multiple roles in cybersecurity. Their ability to monitor, analyze, and
respond to a wide array of signals makes them invaluable in areas like network security, threat detection,
and counterintelligence.

Network Security and Monitoring

One key application of SDRs in cybersecurity is network security and monitoring. Traditional security
tools typically focus on data packets and higher-layer protocols, but many sophisticated threats operate
at the physical and link layers, where conventional tools may lack visibility.

SDRs bridge this gap by monitoring the electromagnetic spectrum for unusual signals. They can detect
unauthorized wireless devices, rogue access points, and other malicious entities attempting to breach
network security. By analyzing signal characteristics and behaviors, SDRs can identify and neutralize
potential threats before they cause damage.

Moreover, SDRs are essential for securing wireless communication channels. In environments where
wireless communication is prevalent, such as corporate offices, military bases, and critical infrastructure,
SDRs can detect and mitigate attempts to intercept or disrupt communications. This is crucial for
protecting sensitive information and maintaining the integrity of wireless networks.

Threat Detection and Analysis

The ever-changing nature of cyber threats demands equally dynamic detection and analysis tools. High-
performance SDRs excel here due to their ability to capture and analyze a wide range of signals in real
