How can SonicWall devices be protected from DDoS attacks?

SonicWall devices can be effectively protected from Distributed Denial of Service (DDoS) attacks through a combination of security measures such as bandwidth management and attack detection algorithms. These measures are designed to identify and mitigate incoming threats by analyzing traffic patterns and limiting the impact of malicious activities on network resources.

Bandwidth management allows SonicWall devices to allocate and optimize available bandwidth, ensuring that legitimate traffic is prioritized over potential attack traffic. This helps maintain service availability even during an attempted DDoS attack. Attack detection algorithms play a critical role in recognizing the signs of unusual activity that typically characterize DDoS attempts. By detecting these patterns early, the system can take appropriate countermeasures, such as blocking or throttling suspicious traffic.

In contrast, simply installing additional hardware appliances may provide some enhanced capabilities but does not inherently prevent DDoS attacks unless those devices have the specific functions and configurations to counter such threats. Increasing the network speed could potentially alleviate some symptoms of a DDoS attack but doesn't address the core issue of the attack itself. Additionally, reducing the number of active users might decrease some network traffic but does not provide a strategy for resilience against attacks targeting the infrastructure. Therefore, option B describes a comprehensive approach that integrates multiple layers of defense to safeguard against
