What is one primary use of the Aircrack-ng utility suite?

1. Password cracking

2. File transfer

3. Data encryption

4. Web filtering

The correct answer is: Password cracking

The Aircrack-ng utility suite is primarily used for password cracking, specifically for wireless networks. It is a robust toolset designed to assess the security of Wi-Fi networks by capturing packets and analyzing their content to recover encryption keys. The suite can utilize various attack methods, such as dictionary attacks and brute-force attacks, to test the strength of the security keys used in wireless protocols like WEP and WPA/WPA2. By breaking these keys, security professionals can determine the vulnerabilities in wireless network configurations and assess how susceptible the network is to unauthorized access. This function is critical for network security assessments and penetration testing, where verifying and strengthening network security is crucial for protecting sensitive data and maintaining overall network integrity. Other choices like file transfer, data encryption, and web filtering do not align with the primary capabilities of the Aircrack-ng suite; these functions are typically fulfilled by different types of software or utilities designed specifically for those purposes.
