It restricts the availability of network resources to endpoint devices and users that comply with a defined security policy. The NAC can also provide endpoint security protection such as antivirus software, firewall, and vulnerability assessment with security enforcement policies and system authentication methods.
A software-defined radio (SDR) is a wireless device that typically consists of a configurable RF front end with an FPGA or programmable system-on-chip (SoC) to perform digital functions. Commercially available SDR hardware can transmit and receive signals at different frequencies to implement wireless standards from FM radio to 5G, LTE, and Wi-Fi.
