A security analyst is reviewing network vulnerabilities for a new office deployment. Which type of network is inherently most vulnerable to eavesdropping attacks due to its broadcast nature, making strong encryption a critical security control?
Bluetooth
Wired
Wireless
Near Field Communication (NFC)
Wireless networks are particularly susceptible to eavesdropping because they transmit data over radio waves, which can be intercepted by any unauthorized individual with the proper equipment within signal range. Encryption is essential to ensure that even if data is intercepted, it cannot be understood without the correct decryption key. Wired networks can be tapped, but this requires physical access to the cabling, making it less susceptible to passive eavesdropping than wireless. Bluetooth also uses radio waves but is designed for short-range communication, limiting its exposure compared to a typical wireless local area network (WLAN). Near Field Communication (NFC) operates at an extremely short range (a few centimeters), making eavesdropping very difficult.
