In a wireless security assessment, what is the primary legal requirement before performing active SDR attacks such as jamming or injection?

Using only open-source SDR software

Ensuring the attack is performed on a frequency above 1 GHz

Obtaining explicit written authorization from the system owner

Registering the SDR device with the local telecommunications authority

What is the primary goal of protocol reverse engineering in the context of wireless security assessments?

To increase the transmission range of the wireless device

To improve the signal-to-noise ratio of the captured signal

To understand the protocol's structure and identify potential vulnerabilities

To convert the signal to a different frequency band

You are analyzing a signal that uses differential encoding. You have demodulated the signal and obtained a sequence of bits. To decode the original data, what must you do?

Apply a forward error correction algorithm.

Compare each bit with the previous bit to determine the original data.

Remove the preamble and sync word from the sequence.

Reverse the bit order of the entire sequence.

In a software-defined radio (SDR) receiver, which component is responsible for converting the analog radio frequency signal into a digital format that can be processed by software?

Analog-to-digital converter (ADC)

Digital-to-analog converter (DAC)

What is the primary role of the software component in a software-defined radio (SDR) system?

To perform signal processing tasks such as demodulation and filtering

To amplify the received signal to a level suitable for the ADC

To physically tune the antenna to the desired frequency

To convert the digital signal back to an analog waveform

Practical SDR Attacks GAWN Practice Questions (Page 1)

Part of the Advanced Wireless Attacks domain, which makes up ~19% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–15 in this domain), expect 3–5 from this objective — we provide 35 practice questions to prepare you well beyond it.
