Solution

Protecting against Distributed Denial of Service (DDoS) attacks is a critical concern for securing critical infrastructure. DDoS attacks aim to overwhelm systems with a flood of traffic, causing service disruptions and potentially compromising the availability of essential services. Ensuring robust defenses against such attacks is crucial for maintaining the functionality and reliability of critical infrastructure systems. Why Other Options are Wrong: a) GDPR compliance is related to data protection and privacy rather than specifically securing critical infrastructure. b) Securing endpoints from malware is important but not specifically focused on the unique challenges of critical infrastructure. d) Managing software development lifecycles is relevant to software development processes rather than critical infrastructure security. e) Encrypting database queries is important for data security but does not address the broader concerns of securing critical infrastructure.
