Ethical Hacking Essentials Practice Test

Which practice can enhance the resilience of systems against DDoS attacks?

1. Implementing multi-layered security protocols

2. Reducing server access

3. Disabling firewall log analysis

4. Increasing connection timeout duration

The correct answer is: Implementing multi-layered security protocols

Implementing multi-layered security protocols significantly enhances the resilience of systems against DDoS attacks by adding various defensive layers that can detect, mitigate, and absorb harmful traffic. These protocols work in tandem to create a more robust security architecture. Multi-layered security can include techniques such as load balancing, traffic filtering, and rate limiting. By distributing incoming traffic across multiple servers, a system can better withstand high volumes of requests during an attack. Additionally, using intrusion detection systems (IDS) and web application firewalls (WAF) as part of this layered approach allows for real-time monitoring and filtering of malicious traffic, reducing the impact of DDoS attempts. In contrast, reducing server access may limit user experience without providing adequate defense against the overwhelming nature of DDoS attacks. Disabling firewall log analysis can actually hinder the ability to monitor and respond to attacks effectively. Increasing connection timeout duration might offer temporary relief during an attack but does not address the root cause or the volume of malicious traffic attempting to overwhelm the system. Hence, multi-layered security protocols present a comprehensive solution that systematically mitigates various types of DDoS threats.
